A complete protein is a food that contains all nine of the essential amino acids in high enough amounts for our bodily functions. Typically, complete proteins are animal-based foods, such as meats, poultry, fish, milk, eggs and cheese. The only plant-based source of complete protein is soybeans. Complete protein sources contain all nine essential amino acids; these amino acids are considered essential because our bodies need them to function optimally and cannot produce them on their own. Complete proteins are most often found in animal-based foods (meats and dairy), as well as in some plant-based sources like quinoa and soy.

It’s the total amount of protein you eat over a day, not the specific type of protein you eat, that matters. Research has repeatedly shown that consuming about 30 grams of protein at mealtime. What matters is the quality of the protein, and how much of it is complete. Only complete proteins are used to rebuild your muscles. Another reason to care about the completeness of protein in your sports drink is that the nitrogen fraction of any incomplete protein must be.

Your muscles are made of protein. For your muscles to grow stronger, they need protein. If you are causing micro-injuries to your muscles by working out, protein is necessary to heal them.

Whether you have an intense workout plan or an active lifestyle, protein equips your body with what it needs to build the muscles to do what you want to do. Protein exists throughout the human body and is found in muscles, bones, skin, hair, organs, and tissues. It makes up the building blocks of enzymes, which are necessary for distributing oxygen to body parts through the bloodstream. Every human. The complete protein A complete protein is a protein that contains all of the essential amino acids, in an adequate proportion.

Not all of the proteins containing all essential amino acids may be called “the complete proteins”. Correct proportion, sufficient to support the biological functions of the body, is what makes one protein complete. Some proteins, mainly from animal sources, are called complete proteins. They contain all the essential amino acids needed for the body to use.

The incomplete proteins lack all the essential amino acids, therefore, requiring additional proteins to make them complete. A food is considered a complete protein when it contains the nine essential amino acids that our body cannot produce on its own. Let’s back up for a second and talk about amino acids. They’re organic compounds that are considered to be the “building blocks” of protein. A quick refresher from science class: Protein is comprised of 20 amino acids; 11 of these amino acids are produced by the human body.

For good health, we must get the other nine amino acids (called “essential amino acids”) from the foods we eat. When a food contains all nine of these amino acids, it is called a “complete protein.”.

List of related literature:

Complete proteins are those that contain all the essential amino acids in the quantity and proportions necessary to maintain healthy tissue repair and growth; incomplete proteins, on the other hand, lack one or more essential amino acid.

The composition and amount of amino acids is important because an excess intake of protein results in the overload of urea-related metabolic waste in the liver and kidneys.

Proteins are essential in the body not only as structural components but also because all enzymes are proteins; many of the hormones that integrate metabolism are proteins, and so are large macromolecules such as haemoglobin.

This was because their previous energy intake was inadequate; increasing their energy intake both spared dietary protein for the synthesis of tissue proteins and provided an adequate energy source to meet the high energy cost of protein synthesis (Section 9.2.3.3).

This is because three-dimensional protein structures are much more strongly conserved in evolutionary terms than primary amino acid sequences, and it is the threedimensional protein structure (rather than the primary sequence) which actually carries out the biochemical function of the molecule.

Because the body breaks proteins down into amino acids and redistributes them, food combinations with incomplete proteins have the same effect as a complete protein.

After the limiting amino acid is used up, the body uses the remaining amino acids to produce energy instead of making proteins, because dietary protein cannot be stored for later use in the way that carbohydrates and lipids can.

  • Actually except for processed food, all vegetables have complete proteins. Would be weird for anything living not to contain them all if you think about it.
    Composition is another thing though

  • I don’t know if it was answered but you cannot consume 2000kal of veggies mentioned per day, lettuce for example. You body can’t digest that amount in 24h. 2000kal of lettuce is 13.3kg. It’s about cubic meter of lettuce. That why animal do eat grass most of the day. Coz it’s not very calories efficient

  • I am 73 and have not used supplements.
    Been on plant based diet for 41.
    Don’t eat meat at home and no dairy.
    I never heard of B12 untill resent years.
    I have been very healthy without B12 for 41 years!

  • OK, Very informative video with lots of good info in short time-frame nice, howeverwhat about Dr Gundry with vids currently showing interviews with him on you tube channels saying we need to cut out Lectins [ whatever they are although I’m still not clear on exactly what they are apparently harmful to our gut health ] out of our diets and beans [apparently all types] was one of those he referred to.

  • Problem is eating too many plant products you could reach a limit due to anti-nutrients which you can only process so many of. We only make so much phytase, etc.

  • Alright, look at this out of interest:
    Gorillas are primarily PLANT eaters. They weigh on average 400 pounds (180Kg). They eat on average 20Kg of plant foods per day. That means they eat on average about 100g food per/Kilogram Body Weight.
    Now If I was to eat a Gorilla diet according to my Body mass which is 64KG, I’d have to eat about 6.4 Kg of RAW plant foods per day.
    This means, 6Kg of a ‘Green apple diet’ would give me: (Low Fat, Low protein)
    Calories
    3120
    % Daily Value *
    Total Fat 10g 13 %
    Saturated Fat 1.7g 8 %
    Sodium 60mg 3 %
    Total Carbohydrate 829g 301 %
    Dietary Fiber 144g 514 %
    Sugar 623g
    Protein 16g 32 %
    Vitamin D 0.00mcg 0 %
    Calcium 360.00mg 28 %
    Iron 7.20mg 40 %
    Potassium 6420mg 137 %
    However, if it was let’s say a ‘Mustard Greens diet’, it would give me a shocking Surprise! See below…
    Calories
    1620
    % Daily Value *
    Total Fat 25g 32 %
    Saturated Fat 0.6g 3 %

    Calcium 6900.00mg 531 %
    Iron 98.40mg 547 %
    Potassium 23040mg 490 % (Again we see a low fat fat diet, but with plenty of Proteins, And sufficient Carbohydrates)
    But humans arn’t Gorillas, and there’s no way that I can eat 6Kg of Raw greens. However, an Adult Male Gorilla DNA allows him to grow to 180kg. The human DNA allows him to grow to about Half of that, i.e. 90kg. So, If I’m Following a Strictly Gorilla Diet, according to my HUMAN DNA, Id have to eat about 3kg of greens per day. This would STILL give me All the Calcium, Magnesium, Iron that’s reccommended.

    My hypothesis is that if vegans dont get enough proteins from their diet, it’s because they Dont Eat ENOUGH. And also because they dont eat ORGANIC. Inorganic plant foods are literally on par with Junk foods void of minerals and vitamins. Studies show nutritional differences of 3-20 times.

  • You forgot to mention bio availability of plant proteins. DIAAS is a measure of the bio availability of various protein sources. Most meat and dairy products have 100% bio availability. Chickpeas have 72% bioavailability, black beans 65% tofu(non gmo without roundup pesticide residues) 54%, pea isolate 82% etc.

  • You can get all the B12 you need from nutritional yeast and yeast extracts like Marmite and Vegemite tiny amounts is all you need!

  • He didn’t talk about seafood. I’m a vegan who eats small types of seafood because it’s a great source of protein. I eat it once a week. Seafood really shouldn’t be grouped with other animal products because it’s very different.

  • Oh wow. I have been vegan for a year and I didn’t know up until now that the protein combining was a myth. So many misinformed vegan advocates out there that don’t even give the right advice. Thank you dr Greger!!!!!

  • I have a family member who really wants to build muscle and follows body builders, and tries to eat like them. I’m vegan and trying to show them that they really don’t need animal protein. These body builders talk about how animal protein is more easily absorbed into the body than plant protein. I’m trying to find some evidence of this. Does anyone know if this is true or have any resources on this in particular?

  • Alhamdulillah someone finally being non-biased or triggered whilst talking about plant based vs omnivore proteins. So sick of all the arguing man. Stop stressing about pushing opinions on people because at the end of the day it’s that stress that’s going to kill you quicker than either of these dietary regimes.

  • Always highlight non vegans have high numbers of B12 deficiency. Everyone should supplement. It’s not about meat it’s about sanitation. Also let’s be clear about vitamins and minerals. Standard American diet is inherently deficient.

  • If you want to prove your point, help a vegan cyclist race at the Tour de France. Then we can discuss whether complete protein is a myth.

  • So could i be healthy on a variety of fruits and vegetables without eating grains and legumes or seeds? Just strictly vegetables and fruits??

  • Great information. Dr Barnard is very knowledgeable. Gorillas and horses are jacked but so are lions and Tigers. It would be great to hear a respectful debate between Dr Barnard and Dr Paul Saladino. Thanks for the interview.

  • Wait…he said the body strips and recycles protein from itself. Isn’t it bad when the body strips off protein? When it does this with calcium with pregnant mothers it causes bone loss and bad teeth, How is the protein thing different?

  • It’s unbelievable how much influence industry has on people. They basically lied to public with their sh***y ads and “studies”. Thanks for doing this!

  • love this video except that you said that meat is the only source of complete protein, but this is not true, because soy and quinoa.

  • No, disgraceful misinformation about children. Children should not be vegan during the most important developmental stage of their life. Stop deleting comments.

  • It’s strange but there is only 2 g of protein in 100 g of brocoli…I don’t know about you but I am not able to eat more than 2 kg of brocoli per day…. ��

  • Hi, I’m trying to construct/understand, fully, the argument to refute/debunk the food combining myth. Directly and with scientific sources. However, many materials, even the video above, use slightly roundabout ways to present the case, and oftern do not directly address it. I have a friend who recently did a training where they were specifically taught this theory and her being straight out of training, my unresearched arguments are weaker. “This is not true” is not an argument, that is a claim. An argument would contain proof and sources. The video above, which I found whilst searching for material, both scientific and popular, does not present the full argument. The articles flashed on the screen look scientific but the titles do not direclty address the quesion (I will nevertheless try and look them up, to see, if their bodies do). It can be seen as using roundabout pointers. In myth debunking this leaves too much room for potential other fallacies. So can someone help me with either constructing the argument or at least point out scientific evidence to counter the claims of food combining? I’m confortable with dwelling into scientific papers, but one needs to dive in from the right end of the pool, with right keywords to avoid wasting time. And by looking at both sides, independently of what one believes or wants to believe. I might end up with the construction of convincing opposite arguments as well. Whatever the data.

  • So lets be realistic here shall we. 50 grams of protien a day.
    To get 20g of protein, you need to eat a whopping 500g of steamed broccoli. Thats over 8 serves of broccoli!! Definitely one way to hit your 5 a day or 7 a day, but that’s a heck of a lot of broccoli to eat for one meal. Alternatively you can get 20g of protein from just 70g of grilled steak.
    I live an active life surfing, motoXcycle riding, skate boarding, mountain bike riding and many more individual sports and I am in my late 50’s. What a load of BS have a cow man.

  • Is Michael Greger s resaerch valid?
    Like there are some paid studdys, some studys that support a movement like the vegan 1.
    I mean thear is also the lchf experts and nutritionist an people claiming that they are healthyer and more energetic on it have way better blood work and stuff like that.
    I want some proff that he has valid information.

  • Methionine is found in sufficient levels in rice alone.

    Same with legumes and lysine.

    Anyone consuming, say, ONLY white rice plus a vitamin c, a, and b12 supplement would not become deficient in any amino acid (or anyhing else so long as rhey got sunlight) no matter how long they ate like that.

    Same with legumes.

  • The vegan diet is only half true. Yes the biggest animals are “vegan”, but they always leave out the fact they are RAW vegans. Those animals don’t eat cooked protein. That’s why they are so big. They literally graze all day and have the stomach acids to do it. We would have to juice that amount of greens. We need to get our protein that is already bioavailable, but cooking destroys the protein. Our bodies want amino acids, NOT protein. So, for TRUE protein, juice your greens and soak raw nuts and seeds. Done

  • He answers the same questions all the time with fake ADA data. If you are taking a supplement it’s because your diet lacks it. You eat a high oxolate diet over time you will get Primary Hypooxaluria. Vegans Drs know any diet needs 3 generations for an effect to be present. He’s a quack.

  • I’m not a vegan nor do I promote any specific diet. I believe a vegan diet can be healthy as long as vegans get all their nutrients as naturally as possible.

    Here is one nutrient that vegans must be aware of and make sure they are getting in their diet:

    Vitamin A. Naturally through foods only. The conversion rate from beta-carotene to retinal is only 20-1. And half of the population has a genetic mutation that would make the conversion rate even worse, somewhere around 40-1. The conversion rate from animal based retinol to retinal is about 1-1. Retinal finally gets converted to retinoic acid, which is also extremely vital to our bodies needs, such as the function of iron.

    This is only one nutrient. I have more that I can talk about but I’m not sure if anyone will even take my first recommendation seriously. I’m not here to start any debates. I’m just trying to help.

  • 100% OF FOODS IN THEIR NATURAL STATE (WHOLE RAW) ARE “COMPLETE PROTEIN”. IF YOU THINK I AM WRONG, LOOK UP US GOVERNMENT WEBSITE “NUTRITION FACTS”. SEARCH EVERY HEIRLOOM/SEEDED/NATIVE FRUIT AND VEGETABLE FOR “AMINO ACIDS”. “INCOMPLETE PROTEINS” ARE 1.INVENTED (GRAIN, SOY, ETC) 2. COVER CROPS (LEGUME) 3. REFINED (GRANULATED, LIQUEFIED, COOKED, POWDERED, DEHYDRATED, EXTRACTED, FERMENTED). EVERY SINGLE “FOOD” IN THE AMERICAN DIET IS REFINED OUT OF ENZYMES, HOW “PROTEINS” COMPLETE IN THE BODY. THIS CAN BE PROVED UNDER THE DEFINITION OF “DENATURED PROTEIN” UNDER WIKI, FOR EXAMPLE. BELOVED

  • It’s interesting the way he says ‘cows don’t make calcium’. Of course they don’t. It’s an element. No one can make it. But they absorb and deliver it. To use that to say that milk is useless is I think a questionable method

  • The cows get protein from grass, so just eat grass; simple. Where does the grass get the protein from? Just eat what the grass eats; water thats traveling through dirt. Drink dirt water, its simple.

  • The sad thing is that even Vegans seems to still be as obsessed with “proteins” as the average carnist.
    In reality we don’t need to be thinking about trying to get enough protein.
    You can completely throw out the beans, lentils, nuts and seeds and still be perfectly fine.
    Eating fruits and greens exclusively will give about the same amount of proteins/aminos per calorie as mothers milk.
    Plenty enough to build strength and perfect health.

  • Portien thoery came from USSR and Nazis. Starving Dogs, humans are dogs or fucking monkeys idiots… just like the Food Pyramid is made by Dairy Farmer Corps! America is a Corp not a nation and gives no fucks like any corp.. wake the fuck up… its almost to late for yall

  • The physiques of the elite bodybuilders are not achievable with just pure plants or pure meat alone, they require exogenous drugs. Wish you would have mentioned this.

  • Jesus, i was in nutrition class and hearing my teacher telling all the jokes i mean jocks about protein combining just made me wanna flip a table, i have many regrets

  • Can you suggest what would be the best diet for a person who wishes to build a substantial amount of muscle but also wishes to live into their 80s? It seems like the most muscle-promoting protein/amino acid profiles are also the ones associated with heart disease and cancer.

  • This is good evidence that plants can offer sufficient protein with no meat. But this is poor evidence that a single-source plant can offer sufficient protein.

    The very quote you cite says that plant proteins are sufficient “as long as sources of dietary protein are varied.” Of course meat isn’t needed. But varied plants evidently are.

    The gelatin study only looked at 15 different protein sources, it was on RATS, and it is from 1964.

    Good job herding the sheeple.

  • If ye love me, keep my commandments.
    John 14:15 KJV
    Remember the sabbath day, to keep it holy.  Six days shalt thou labour, and do all thy work:
    Exodus 20:8‭-‬9 KJV

    Saturday is the day of the Lord

    The claim that Christ by his death abolished his Father’s law, is without foundation. Had it been possible for the law to be changed or set aside, then Christ need not have died to save man from the penalty of sin. The death of Christ, so far from abolishing the law, proves that it is immutable. The Son of God came to “magnify the law, and make it honorable.” [Isaiah 42:21.] He said, “Think not that I am come to destroy the law;” “till heaven and earth pass, one jot or one tittle shall in nowise pass from the law.” [Matthew 5:17, 18.] And concerning himself he declares, “I delight to do thy will, O my God; yea, thy law is within my heart.” [Psalm 40:8.] GC88 466.3

    Ecclesiastes 12:13 KJV
    Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.

  • He didn’t really talk about how much plant protein we absorb vs meat protein. He talked about calcium but not meat. I was really curious about that stats on that. I’ve heard that we have to consume much more plant protein than we think we need because the body can only absorb a small percentage. Where as a chicken breast is almost completely absorbable.

  • I would drink rat milk, who cares, its just your mind getting in the way to eat this but not that. the fact of the matter is most vegans went vegan then learned how to defend it as yhe superior way of eating, not the other way around. its all a superiority complex, they like to look down at others who arent vegan as less than and gonna die a miserable death while vegans fart rainblows and pee pure mango juice.

  • But I’m not a giraffe or a horse, I can’t be a carnivore and Except to be healthy like a Lion. Also can all the protein absorb?

  • But here is the twist, plant protein is not equal to meat protein, the meat protein has higher quality and with even greater quantities, so animal protein is better

  • Started watching your videos and subscribed to your YouTube and Twitter feeds after watching The Game Changers last night on Netflix. Have been vegetarian for the past 8 years. Have cut out dairy cheese and diary youghurts this year and aim to finally remove eggs from my preferred diet over the next 2 months too. VEGAN-in-process. LOVE your energy and information! I’m thrilled to be on this healthy journey. Thank you ♥

  • Hello!

    Thanks for all the great quality of information accross these videos. Especially proud as I’m also a Portuguese living abroad.

    I have read different opinions that the absortion of plant-based proteins is significantely lower than of animal-based.

    You mention that you will cover this on a future video, but I haven’t seen a part III. Did I miss this reference in one of your other videos?

    My curiosity comes from having had two serious tendon injuries in the past year after following a plant-based for two years now.. wonder if there is a relation given the importance for proper protein absortion in order to heal tendons after exercise.
    There was no obvious movement that led to the injuries, just came up slowly (medial epicondylitis and supraspinatus). These are normal injuries in climbers, but I have climbed for 10 years and have never had a non-trauma related injury before.

    Thank you in advance

  • LIKE IM SO FRUSTRATED OF THIS, SOYA CHUNKS, A COMPLETE PROTEIN, 53 GRAMS OF PROTEIN IN 100 GRAMS, NATURALLY MADE ON COSTS JUST 20 RUPEES(0.25$) AT MY PLACE A KG, THATS ABOUT 553 GRAMS OF PROTEIN PER 2.5$ NO WHERE IN ANY LIST??? LIKE WHAT??!!!!

  • Key concept is “typical american diet”. Which produces an overweight to obese population. But why? A look at the “requirement index” shows that milk and eggs are both in the high 90 % range and are called complete foods because of this. Whole grains are in the 76 to 82% range and peanuts are 67%. Meats, not listed, are higher than grains but lower then say, eggs. Now what does this mean? To me, if you only eat uncombined foods, you need 50% more peanuts(67% plus 50 % of 67%, or 33% equal 100%, no?) to get enough essential amino acids to supply enough for the body to have the the100% complete protein needed to live. Where does the remainder protein go? Some can be used by the body as energy, but some is also stored until the body gets the missing amino acids needed to make it useful for the body. This is called by normal language, fat. That is one reason why the “typical american diet” is so high in calories. Look at nations where excessive calories in the diet are either not available or too expensive and see what they eat. Cuba for example. There is a Cuban joke the goes:In Cuba we eat beans and rice for breakfast, rice and beans for lunch and Moros and Chritianos for dinner (read:beans and rice). There are not many fat Cubans but there are many healthy ones! India and African, same thing. No, you do not have to combein foods to get a better protein complex, unless you do not want the typical american diet.

  • In terms of protein, animal products (egg whites, chicken breast) have higher bioavailability compared to plant products. Does this matter?

  • Those animals he mentioned either have a rumen or a caecum with the correct bacteria that produce the amino acids, My caecum is called an appendix. Another interesting note is that those plant eating animals end up with 70+% of the plant material converted into short chain fatty acids-there are eating a HIGH FAT diet

  • Hello, I like the way you explain all these here. Thank you. I wanted to say that eating animal products may be a choice for the person that purchase them, but it is actually not a choice for the killed or exploided animal.

  • My RD from KP told me “you cannot eat only plant protein” you must eat animals to get all your nutrition….she sat there with all her fake meat for display>barf and I had to pay 20.00 for that consult. Ohhh and only 2 fruits a day because it has carbs and natural sugar.

  • Hi! How about methionine and cysteine, the two sulfur-containing aminoacids? Vegetable proteins have lower levels of these two, if compared to animal proteins. Isn’t that a problem when talking about protein quality and digestibility?

  • If plant proteins are complete then why do my muscles take longer to recover then?

    Wait a minute… so if the body has an amino acid pool… the pool needs to be filled doesn’t it? With essential amino acids which the body can not produce on its own. So yeah at some point you will need to eat to complete the incomplete protein…

  • Thank you so much, that is such a great information for me…. I´ve spent hours of searching for “good” combinations from vegan sources.

  • Nutrition made simple….what is your take on the China study by T. Colin Campbell? Would appreciate your view on its opinion on animal protein.

  • Its been one year since I started doing protein powder. First, it was all fun, and I felt great. I was drinking it after every workout, every night before I went to bed… it was a great experience. But my obsession grew. I started incorporating it into every aspect of my life. Used it on my toothbrush when I brushed in the morning… gargled with it. Put it in my coffee. Then it turned detrimental. I would snort lines of it before I went to school. Put it in my pipe and smoked it before work. The next thing I knew, was that I was heating it up in a spoon, and putting a syringe into my biceps. Man was that a great pump.

  • The other day somebody asked me to show the evidence, since Harvard “proved” this and no science has proven otherwise.
    I feel like that seagull at the very end when I hear the word “protein” ��
    /plantbased for 15 yrs and counting

  • Just pick any random 6 whole plant food and it will have all of the essential amino acids in it.

    So which plant food is a complete protein?

    All of them.

  • Thank you. I’m looking at going plant based. 45 yo disabled vet with a two year old. I’ve struggled with mental health stuff, now I’m trying to live to see him grow.

  • Nice to see that there is someone out there that understand amino acids.
    The key is a variety of whole foods.
    A vegan diet does not cause any deficiencies!

  • b12 is made by bacteria…. SO THEN, DOC, EAT BACTERIA?.. no.. b12 vitamin pills? so this is now manufactured right? its no longer then natural… its processed….

  • 中文(繁體) time 1:14. The translation is wrong. (average about twice the average daily requirement for protein. 應該是:平均攝取到的蛋白質的量,是身體需求的兩倍。因為在另一篇 Do vegetarians get enough protein 提到 :The average requirement is 42 grams of protein a day. Non-vegetarians get way more than they need, and so does everyone else. On average, vegetarians and vegans get 70% more protein than they need every day。)

  • Thanks for making these videos. Recently changed to plant based. Feel fantastic and now its comforting to know for sure i’m getting enough protein and Aminos. Kudos��

  • Love your videos! Keep up the work and you’ll get your deserved amount of subs!
    One question though, what is the reason you don’t consume fish? The healthy fats they contain is a reason to go pescatarian imo

  • That bodybuilder/powerlifter section is kinda bullshit. Most of them, if not all, are taking PED’S, plant based doesn’t count then.
    But amazing video nevertheless!

  • Once again thank you Dr Greger for sharing this amazing knowledge with us all, I feel honoured to receive it. I must tell you I just received “How Not To Die” in the post last week. I’m pretty sure I ordered one copy, but Amazon sent me two!

    Either way if I did pay for two it is no worry, I can’t wait to start reading it and I will give the other away as a gift to someone who deserves it:-)

  • I love the fact that bodybuilders are vegan and use a vegan diet but realistically the one you showed on here is very debatable, almost a bit of a joke that he denies being on steroids. I’d wish they’d just come out and say, as there is nothing wrong with that, but there is in folk thinking they can get those gains from either meat or a plant based diet and nothing else its misleading. Even if your a meat eater of vegan, there is allot of untruths told in how they got the body they have. The truth is if your gonna do steroids its better to do it on a plant based diet such as a vegan diet as its allot less harsh on your organs especially the kidneys due to all the creatine in cooked meet causing high levels of creatinine. BTW I lift weights and love this channel so I love the advice on here. Keep up the good work. Subscribed and watching your videos:-)

  • Isn’t lysine typically hard to get enough of if you don’t eat beans? So, then, minus beans, it seems fairly easy to design a diet that is deficient. I mean, if you eat less lysine than is needed every day, the “pools” of amino acids that the body has access to is going to be deficient in lysine. Isn’t this true? If the RDAs are correct that is?

  • Watched both your protein videos, they were very informative. One suggestion is that the music was a nuisance. Can’t hear your voice clearly.

  • Yes! Tons of protein, but are those protein foods species specific to humans and bioavailable in the right quality and proportions? NOPE!! The vegan diet is a starvation diet!

  • 4:17 Vitamin B12 is made by gut bacteria.
    Vitamin D <= Sun Light 20 minute, to absorb Calcium.
    Dark Green, Leafy Vegetables.
    अंजीर, सफेद तिल

  • The info was good but the background music was a bit annoying. Could you experiment with something different? Perhaps not blasting it all the time, specially when you’re talking. Duno, have a look some YouTube channel that you particularly like (and/or that has been successful) and check what they’re doing with the musical effects.
    PS: A grammar error: “algae” is the plural form of “alga”, therefore “is an algae” is grammatically incorrect.

  • 1:30 “The concept that plant protein was inferior to animal protein arose from studies performed on rodents more than a century ago. Scientists found that infant rats don’t grow as well on plants. But infant rats don’t grow as well on human breast milk either…”

  • Nor is a plant-based diet the equivalent of grazing on grass.
    Just because both species eat plants does not at all mean that a cow’s diet is good for us and vice versa.
    Our physiology does not resemble a cow’s and, therefore, we don’t gain nutrition in the same way.

    In fact it is important to point out that every animal is different; we simply can’t compare ourselves to other animals—especially true herbivores.

    At the end of the day, comparing human’s nutritional requirements to the needs of a true herbivore may well be counterproductive to a constructive dialogue and thorough understanding of a plant-based diet.

    Step down from your moral-authoritarian highground and educate yourself.

    No, you can not get “150 grams” from the broccoli that you eat. The bioavailability of plants is not comparable to meat!

  • Holy shit man, Plants are packed with protein, where do you think animals get their protein to begin with? Also, you really don’t need much protein anyway. Just B-12 (not only vegans but meat-eaters as well) and Omega-3

  • As soon as the man compared a cow diet basically to a human diet I stop listening. For people who live animals that was arguably the most stupid thing I heard from a doctor

  • Not a bad video, however just to clarify that their are complete plant proteins with all mobile me essential onp acids. Soy products are the most well known and widely used, though their are many others.

  • Thanks for the breakdown! I was using the Cronometer app for a year, and I always got enough protein as you say, but I often didn’t reach the goals for every amino acid everyday. Are you familiar with the app, and do you think they set the thresholds too high?

  • This is the one video you have I think every single human on the planet should watch. How can such stupidity still be the main argument against veganism?

  • I knew about the fact that it is not necessary to combine food at each meal.

    But still i’m confused about something, according to the video i don’t need to worry about combining my food like… AT ALL? Like let’s say that for a week, i don’t feel like eating any whole grain food… It’s okay to just eat lentils, beans, vegetables without worrying about that ‘combine whole grain and beans’ argument?

    Hope i’m clear enough, i’m not english native, it is not even my second language.

  • All you need is a variety of whole foods. THIS SUPPLIES MORE PROTEIN THAN THE BODY CAN USE!!!
    No need for any complete proteins in the diet.!!

  • good video but its a big myth that only animal proteins are complete protein sources. Actually almost all foods are, except if they are processed they might lack in some amino acids.

  • I’m currently finishing my bachelors in Food Science and Human Nutrition and this myth is still perpetuated throughout my classes. I’ve had at least three separate professors teach this as fact and it’s so frustrating.

  • Im reAlly interested in the vit d3 and vit D2…I had read that the vit d3 is actually what is most important for the body but any plant based supplement or fortified food actually used vit d2 so does this mean that we are still missing out?

  • This video is a complete joke. You know people can READ right? Especially at 2:50 and 3:07 The bullshit you’re saying doesn’t match the science papers you’re showing. Especially at 3:07 you say with condescension “no need to combine”.. when the fucking statement clearly reads “as long as sources are VARIED”

    The response from AHA is NOT that any single plant has complete protein, as it doesn’t, but infact that IF you’re eating rich DIET of varied vegan based foods, then you’ll end up with enough protein.

    That CONFIRMS protein combining.

  • At 3:07 the pop-up includes ONE PHRASE that NutritionFacts.org leaves out. When talking about combining proteins, the recommendation in the pop-up says there is no need to worry about combining proteins WITHIN A GIVEN MEAL. It is still a good idea to know your protein sources and to make sure that you include a variety of protein-rich food in your diet (so you’ll get all your amino acids). So, don’t forget to add a handful of nuts, or to have beans, grains, etc. every day. You can’t just eat one source of most proteins (such as processed faux-meats) and hope to be okay.

    Also just a pet-peeve, but we are lucky to live in a time when we have research data. In the past, we didn’t know a lot about a lot of things (we hadn’t invented the instruments of measure that would allow for the precise sorts of information that we have now). In the past, we were ignorant. That is different from being intentionally misleading. Now that we know better… we can do better.

  • Phenylalanine was found exclusively in animal products prior to the agricultural era. Had it not been for thousands of years of cultivation and trade allowing people from all over the world to eat man-made nutritional ‘powerhouses’, most of humanity would have died eradicating meat from their diet.

    You can live off of plants NOW, but even then you run into problems sourcing your amino acids from specific foods (estrogenic properties, raw veganism being a myth (soy is poisonous raw), consumption of phytic acid, and still tons of vitamin deficiencies). We didn’t get our B12 from water; Veganism is still bullshit.

  • You might not want to be giving nutrition advice if you consider broccoli, bananas, rice and cherries protein sources. All those have less than 2 grams of protein per serving. Also don’t trick people by saying per 100 calories because of course plants have less calories but it doesn’t change the fact that the protein in them is very small. Study the macronutrient breakdown and serving size so you don’t get tricked by people like this guy.

  • Me encanta la forma en la que presentas la información ��. Das posibilidades a todos, mostrando la verdad sobre la ciencia de la nutrición y rompiendo mitos que hacen más daño que beneficio a las personas.

  • Then, could you make a video explaining which are the health issues a 100% plan based protein could bring, such as SiBO and so? please. Love your videos

  • Science without common sense has always resulted in dietary fallacy. You can even question NutritionFacts.org for recommending the direct consumption of plant reproductive material. Not only are beans, seeds, whole grains,,rice etc protected by Anti-nutrients and damage the gut. The benefits they are touting are bio-unavailable until sprouting and germination takes place. Remember if you can’t consume something raw without some form of process like cooking, chances are nature never intended it to be a dietary staple.

  • But the question is can we absorb them all from plants? And for example, Carl Lewis failed PED test on that same Olympics, Kyrie’s stats dropped since he switched to plat based and he got injured later. o not good pics. Harris made his top lifts when he was an omnivore, check when he switched and then look at his career. I am not saying it is not possible, but they are not so good examples.

  • Why can’t one person just give samples of a healthy day of vegan eating with all the needed protein. We just get a lengthy lecture. Just show me where you got your protein yesterday. Let me see it. Not what my ancestors did. What did YOU do yesteday. We want an answer; not a lecture.

  • Just giving up all animal products will not make you slender or healthy. You have to give up unhealthy plant based foods, and pigging out on sweets.

  • I love these videos! Am I correct that a part III covering absorption has not been made up to this point? I can’t find it and I would really like to watch it

  • Isn’t the idea behind incomplete proteins the ratio of certain amino acids to others or even absence of some amino acids? (like essentials vs non-essential)
    So saying they are incomplete may technically be wrong, but if you take incomplete to mean not optimal human use or not containing all of our essential and semi-essential amino acids, would that also be a myth, or does that interpretation actually have some validity?
    It could very well be the case that proteins from meat are more optimized for say muscle growth, because it’s already a muscle, whereas plant-bodies are very different from our bodies in terms of structure. I haven’t looked into the research on this, but if anyone who has cares to comment on this, I would be very interested to know if what I just said holds any truth.

  • Wow. I was believing that eating a lot of animal foods was the healthier way. I’ve changed my mind. Now only a small percentage of my calories comes from animals. I think that’s a reasonable balance.

  • Real gotcha moment when you caught AHA saying “you need to eat multiple plant protein sources” and then correcting it with “you need to eat multiple plant protein sources”

    If you’re going to misrepresent what sources actually say, don’t quote them.

  • where can i find more info about plants producing amoni acids while humans and animals just recycle them.
    all i find is info about humans and animals producing non essential amino acids themselves

  • Sun, cholesterol and a series of skin interactions that can be easily interrupted by washing / water / sun-blocker provides vitamin D to the body. Let’s hear it for cholesterol, which if we have too little actually shortens our lives or even kills us. Our body actually produces a lot of cholesterol, unlike vitamin C (which almost every other creature out there does make). We can survive without much vitamin C, but apparently we cannot survive without cholesterol. Perhaps we can fix the gene that is supposed to make vitamin C, but I have not heard anyone propose that.

  • What foods should you eat to cure nocturia/frequent urination? I want to eat plant-based and am under the impression that amino acids can heal the bladder/these problems. I remember drinking bone broth with plenty of gelatin and was able to sleep without waking up at all that night. I haven’t been able to do that for years.

  • He doesn’t quickly answer the question…..seems to be a slippery answer as he doesn’t really define protein…..the problem isn’t getting protein which is a common cell type…but getting proteins of the right type in the right forms that can be absorbed by the body….not very clear

  • I just took an online course, allegedly supported by Stanford university, and it had that protein myth about combining proteins in it! I guess I knew the course was a low quality one when they preached healthy eating and then proceeded to promote recipes full of eggs, diary and oils….
    Thanks Dr. Greger and Team

  • why do these vegans always compare elephants and rhinos and horses to humans? the fact that humans are NOT huge like an elephant suggests we ARE NOT herbivores and are not meant to eat like one. one bunch of broccoli is about 20 grams. so you’d have to eat three of them to get enough protein in a day. but he doesnt tell you that 60 grams is meant for a “sedentary” man, so basically just enough protein to keep you alive, and not for optimal health. and he doesnt tell you that plant proteins are not as easily digested compared to animal protein. so how much of that broccoli protein are you actually getting? you’re not getting the full 20 grams. and also, vegetable proteins are missing amino acids, so they are not “PURE” protein. he lies by omission.

  • To have a really good comparison of the muscle building properties of meat vs plants you would have to do an experiment with the same athlete. No doubt they have great genetics and can thrive on a plant based diet but that doesn’t automatically mean it’s optimal.

  • You can but the of food is a lot and tofu is boring peanuts boring legumes boring in a vegan diet if you don’t just love veggies and fake tasting substitute products it sucks. Being a vegan is serious work it becomes the center of the universe. Just too much work. I was a vegan for several years. Yes I’m selfish yes I eat animals no I dont gaf about your feelings

  • Another question. If animals obtain their protein from plants too, then why does we obtain more protein from cows than from other animals?

  • Excellent Podcast! Very Cooperative talk and important details mentioned for each question! Well done, please keep making such gems!

  • Dr Neal Bernard very true by change food diet 96%)
    can solve lot of problems in body health within 3 day I can feel change’s thank you Dr. Neal Bernard

  • Agreed, there is protein in plants and animals do have to eat a lot of plants to get their protein, but I thought we had different length intestinal tracts to process the plants? Our intestines look more like that of a dog than a gorilla.

  • So i don’t have to combine meats? Any meat will give me all the proteins my body needs?
    Great, because eating meat has been a tradition in my family for millions of years.

  • According on alot of people i met, I should be dead 100 times from proteine deficiency if they were right… I love being a living example of their wrongness about that saying ”Hi” every morning with a smile. That’s my reward. xD

  • hi doctor can u make a video about PDCAAS.

    I am a vegan powerlifter since 2 months and I don’t feel like I am recovering after my workout like before. I am eating the same amount of protein but they are from plants. so bioavailability of them is not as high as meat or animal protein.

  • Refreshing and inspiring ��. Thankyou. As you are focussing on protein, here is one question (set of questions on protein) I have yet to answer is how much protein do I really need when working out each day? Does muscle repair/rebuild primarily occur during sleep (and naps)? When is best time to eat in relation to workout and amino acid absorption? How much protein can my body store assuming that repair/rebuild takes hours and days? How much can I absorb? They are all interrelated questions, e.g. one thing I do know is that after training to failure I do need a couple of days and nights of sleep to recover �� no study evidence required there.

  • While you don’t need to combine your proteins in your meal, but you do need to make sure you are getting a variety of amino acids at sometime for your body to consume them. If you are deficit from eating them, your body can’t store and allocate them.

  • Wow the people who follow this channel and don’t do any fact checking are fucking brain dead. You are so self absorbed in your vegan bullshit lifestyle you have no idea this guy is full of shit.

  • Can you do a video on strength resistance training with weights. This video suggests that protein isn’t as necessary for that as well.

  • 1600 kcals for you?! I eat 3100, although I’m 25 and workout daily. It is still seems very low for you!:D Or am I sick or something?

  • 1:11 Broccoli + Lentils + Corn for Essential Amino Acid.
    Athlete need Oxygen.
    [ We need 0.8 0.9 gm protein/kg body weight = 30-40 gm protein
    https://nutritionfacts.org/video/do-vegetarians-get-enough-protein/ ]

  • A good protein source I have found are sprouted lintel beans. Cheap, easy and fills you up!   Lintels are made up of over 25% protein, which makes them an excellent meat alternative.

  • Where does he get this nonsense-147 grams of protein in broccoli is 60 cups of the stuff AND 360 carbs. Lentils by his numbers require 9 cups and that is 340 grams of carbs. 360 carbs is the same ad 90 teaspoons of sugar and that folks is why the vegan diet is a diet of malnutrition and in the end game poor health

  • Great video! One omission though…in regards to health chosing animal protein increases cancer risk, cardiovascular risk and all-cause mortality. May be an individual choice for source of protein, but be sure you understand the health consequences: https://www.ncbi.nlm.nih.gov/m/pubmed/27479196/

  • It’s a disgrace that most doctors lack the level of knowledge on nutrition to adequately prevent disease formation and any further metastasis. But, again, the industry of pharmaceuticals won’t flourish on competent citizens.

  • I agree with the basic idea that vegans overthink protein. For instance, I just tallied up what I ate today, which I don’t usually do. I got about 44% of my protein from legumes, 32% from vegetables, 12% from nuts and seeds, 10% from grains, with the remaining points being fruit and me being lazy with rounding. Despite getting about 75% of my protein from food with the same limiting acid, I’m still definitely fine. And so are most vegans.

    That said, you DO need to have a varied diet. If you get a lot of vegetable protein at dinner, and have some grains or nuts in the evening, you’re groovy. It doesn’t have to be the same meal. Or even every day, our body can compensate for shortfalls by recycling protein. But if you CHRONICALLY get all your protein from a single source like grain, you’ll eventually have protein problems. But eating such a stupidly one-dimensional diet is inherently unhealthy, whether you’re vegan or a traditional omnivore, and protein is just one facet of the unhealthiness.

    So basically, yes, limiting amino acids are real, and most plant proteins are “incomplete”. But a vegan with a healthy and varied diet doesn’t need to consciously think about it at all. Which is really the take-away.

  • +Nutritionfacts.org But i dont understand. So if a person eats just broccoli for example, then does that mean that our essential amino acid requirements are met? Which foods contain which amino acids and in what proportions? Too many loose ends in this video for me.
