100 thoughts on “The Great Protein Fiasco

  1. Protein is one of the reasons why humans are the sickest species on this planet. Protein is too hard on the kidneys and it stops their ability to filter lymphatic waste (acids) out through our urine. Combine weak kidney filtration along with the heavy acid forming diets most people eat nowadays, and you're left with "interstitial lymphatic constipation" or "systemic acidosis" (the cause of all humans' diseases). Check out Dr. Robert Morse's channel he's got the science down good.

  2. Breast milk wasn't created by a thinking nutritionist. It evolved the way it is – that doesn't mean that it is the best it could be.

  3. Thank you for this! I thin you will find that the protein madness peaked when it did because the US government decided that Olympic athletes in training were the ultimate in human health, so they scaled our protein needs to optimize us. Olympic athletes in training are the only humans who would need large amounts of daily protein, which is for storage against emergencies. What we need large amounts of daily is Vitamin C.

  4. The crazy part is that all the evidence has been here all along. But the best evidence? Look into an animal's eyes. There is no science that can touch that connection, a sacred bound between each other that we brutally break at our own peril.

  5. Holy schlitz! I remember having to study "Kwashiorkor" in my early college studies…..what a load of crap! They shoved that bull down our throats and we payed for it! I feel so stupid!

  6. One thing not addressed here is are they talking about that amount of protein for the typical lazy person who does no exercise or does that include people such as myself that lift weights 5 times a week and do cardio? I believe most protein requirements are overkill but 66 grams a day is very little…I have to look at the guy that did the video and he has absolutely a non muscular body so his protein requirements very well may lower than mine or anyone elses

  7. Oh ffs, all macro-nutrients have calorie values. If you eat more calories than you burn, you will get fat. It doesn't matter if they come from fat, protein, or carbohydrates.

  8. Thank you for the information, I've been wondering how I've been gaining weight and mass without even counting calories nor protein.

  9. to those paleontology diet nuts, I say "WE do not live in paleontology times and we do not have that body. we have evolved.

  10. I think that your breast milk argument is wrong.
    What you're saying is that humans experience the most growth when breastfeeding, therefore breast milk has the best macronutrient setup for your entire lifespan.
    I'm not saying you're wrong, just that the argument is wrong.

  11. Fabulous! When the world is becoming obsessed with protein shakes and supplements! Well we all know who's peddling it now.

  12. I'm curious if the protein source makes a difference. So, if you eat a high protein diet but you're vegan, do the differences disappear? Perhaps the difference is due to meat and not the high protein. I doubt this study could ever be done though. N too small. Any thoughts?

  13. keep in mind that fiber inhibits protein absorption. That's why vegan RD Jack Norris recommends 1 to 1.1 grams of protein per kg of healthy bodyweight for vegans. For vegetarian athletes it's 1.3 to 1.8. But even at those levels it's not the ridiculous amounts some recommend.

  14. Ha ha ha ha ha! After I watched this video this morning, I went for a routine physical and after my provider told me how great my blood work numbers are, I told her how I'm trying to live vegan as possible, and she said, "make sure you get enough protein"! Ha Ha-ha ha ha ha!!!!

  15. Worth remembering that we're being given an average goal from this (as explicitly stated in the video) – your needs may change, and it's worth experimenting with. I'm personally aiming for around 1.5g/kg, as someone who does at least 10 hours cycling a week, at least 3 hours of which are very high intensity. I think 0.6g/kg is too low given the amount of muscle regeneration I believe I need, and this amount I reach fairly naturally without explicitly searching for protein (vegetarian, not vegan diet) – occasionally needing to supplement with 20g at most if I haven't done a good job planning the days food.

  16. What about satiety and higher thermic effect aiding weight loss? A higher protein intake is positive in this sense right?

  17. "NutritionFacts.org" sounds like some kind of government agency site, but it's really just there to sell this doctor's books. He even has a book titled "How Not To Die". How can anyone take what he says seriously unless they're just using him as a source to forward the beliefs they already hold?

  18. Government agents wrong…. really…. again ? Note to self. * What ever the government agents recommends….DO EXACTLY THE OPPOSITE you will be just fine.
    Your welcome

  19. Proteins are made of amino acids. "Essential" amino acids for children and adults cannot be made by the body. So they must be found in food. The 9 essential amino acids in human diet are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Besides these breast milk also contains Taurine and cysteine, which are necessary for infants but not for older children and adults. Breast milk also contains nonessential amino acids alanine, arginine, aspartic acid, glutamic acid, glutamine, glycine, hydroxyproline, proline, serine and tyrosine. Besides all this breast milk composition can vary among women or vary in the same woman over time. Protein content is highest in breast milk right after birth and decreases over time.

    Cow's milk contains about 3x more protein than human breast milk. Human milk is the only mammalian milk with a methionine/cysteine ratio less than 1.0, a
    characteristic common in "vegetable proteins". Cow's milk (as well as formula milk) is also low in Taurine. There are other differences as well.

    Adult protein requirement depends on genetic makeup, age, sex, body composition, environmental or pathological stressors, physiological stressors. Obviously, a lactating woman needs greater amount of protein in the diet. The most important lifestyle influence that affects protein requirement is physical activity. But, things like smoking and alcohol consumption also affect protein requirement.

  20. Westerners are suffering from protein overdose.  A human only needs about 40-50 grams a day.  Unless you want to be a muscle bound freak and then you can enjoy your ill cardiovascular health.

  21. I can't really follow his argumentation here. If he's going to use the composition of breast milk as a model for our ideal food, then you could also argue that fat is very healthy for us and carbs are not, right?

  22. question your math on protein required seems off, my ideal weight is 80kg(176lbs) therefore 80*.9= 72g protein per day, love the series btw

  23. question your math on protein required seems off, my ideal weight is 80kg(176lbs) therefore 80*.9= 72g protein per day, love the series btw

  24. Exactly. The media in Finnish nutrition is all about protein. I hope people will wake up that fats and carbohydrates are more necessary.

  25. All of this vegan protein advice is from the POV of preventing deficiencies and getting the bare minimum. What about for strength athletes and bodybuilders? Common accepted industry advice seems to be 1g / lb of bodyweight, which is easy to get on an omnivorous diet.

    As a vegan, you would have to eat A LOT of food to get that amount of protein, even from the "high" protein vegan foods like nuts, beans, and quinoa. Tofu is a valid source but it is technically processed and not a "whole" food.

    At the end of the day, a person really has to log their protein intake and determine if they are putting on muscle or not.

  26. You should take a bite out of a green apple before recording. It will help with the sound of extra saliva while doing a voiceover. This is a legit trick we use in voice acting.

  27. I definitely get tired of the always-asked-first-question that vegans get: How do you get your protein?

  28. Many talk about bodybuilding as if it is a good thing. It isn't. Sure, getting as strong as possible and eating well to increase and maintain your top five biomarkers which REQUIRES progressive overload exercise mainly in the form of squats and dead lifts is absolutely necessary for basic life quality, but NOT when you add forced feeding, increased protein and excess food in order to substantially increase your body size. Popular and commercial bodybuilding, especially as espoused over YT is a very unhealthy endeavor.

  29. Human brain grows fastest during breast feeding first 2 years of life.

    If meat is essential part of our evolution and its high protein content is responsible for our brain's rapid growth then why does human breast milk have only 1% protein (even less than chimp, sheep, cow & gorilla's milk) ? This shows that we are herbivores and protein has only small (role) impact (<1%) on brain growth & development.

  30. Omnivore Theory: Animal Protein (in meat) is essential for human brain growth and development. Google it if you have any doubts.

    Fact#1. Human brain grows fastest the first year of life while breast feeding only on mother's milk. Google it if you have any doubts.

    Fact#2. Human milk has one of lowest % (1%) of protein of all animals. Even less than cow (3.4%), dog (7.5%), chimpanzee or gorilla. Google it if you have any doubts.

    Conclusion: Very little Protein (1%) is needed for human brain growth and development. Therefore Omnivore theory is proven false.

  31. Our bodies are very efficient at recycling amino acids. Even if you are a bodybuilder there is no reason to be chugging protein shake 2-3 times at day. All you are going to do is get bloating and gas. I have had great gains from a diet with plenty of beans and grilled chicken.

  32. "By going vegan and doing an 18:6 intermittent fast (dinner to next day lunch = 18 hrs) I up-regulate AMPK and down-regulate mTOR, the same thing that metformin does for diabetics who live longer than people who don't take. We now know that AMPK can be up-regulated by IF, exercise, and eating a whole food plant based diet. This is new science so Google: PubMed, AMPK, mTOR and Intermittent fasting and learn something new."

  33. Wrong. speaker needs to visit India and study how lack of protein causes multi billion dollar sickness among Indians. many are vegetarians and have no clue how to get some animal protein daily. i experimented on my own body. if i cut out animal protein i developed high BP skin became wrinkled so soon i added it and things were normal. it is a major problem for many other countries in Asia ,Africa and Latin America

  34. someone needs to send this information to dr. Now from houston tx. he recommends high protein, low carb to his weightloss patients and it drives me crazy. 🙁 even doctors really think thats the right diet, but its literally flipped. ive lost 160lbs high carb, low fat vegan!

  35. This doctor bases his claim for lower protein intake on the "science" that breast milk contains less than 1% of protein. Yes, breast milk contains about 1% of protein, because 100 g of breast milk contains about 4.4 g of fat, 1 g of protein, 7 g of carb, and 87.6 g of water. If you take the water out of the equation, the fat-protein-carb ratio of breast milk is 35:8:56. If you were to "scientifically" base your optimum protein intake on the protein ratio in breast milk, you should have said 8% instead of 1% (which is misleading).

    Moreover, why not base your optimum fat and carb intake on breast milk as well? Does that mean that you need to be on a relatively high fat-low protein-high carb diet by eating 35 g of fat, 8 g of protein, and 56 g of carb per 100 g of your macronutrients????

    Haven't this doctor been promoting high carb, low fat, low protein diet???

    What's going on?!?

  36. This is so wrong, it's not even funny. First off, infant's bodies are so different from adult bodies, they might as well be different species. For example, the tolerance for drugs. Even something as simple as Tylenol isn't dealt with the same way between adults and infants. one would assume the total dose for an adult would be much higher than an infant because of the increased weight, but mg/kg dosing already takes weight into account, and yet the maximum tolerable dose for an infant is 15mg/kg, while the adult dose is between 20-50 mg/kg. Infants can't eat honey, and they even have a completely different form of hemoglobin in their blood. Basing the adult diet on what a baby needs is a ridiculous endeavor.

    More specifically, with regards to protein, adults have three major differences when it comes to the amount of protein they need. 1. infants have very low muscle tone and weight, their bodies are weak and their metabolism is focused on cellular growth and building energy reserves(baby fat). However, upon reaching puberty, adult bodies vastly increase their skeletal muscle weight, irrespective of training or field of work. 2. Adults have more things to do, places to go, work, athletics, weight training etc. These things build up even greater muscle definition and weight. 3. The biggest difference is that ONLY ADULT bodies use protein as a major energy source (that's right). In order to ensure the proper body composition, adult bodies burn protein, keeping the protein metabolism in check in case of sudden famine, or wasting illnesses. This ensures that if you burn a large quantity of fat in a short time, the body can adapt quickly to return to a healthy composition ratio between fat and bone and muscle. Since infant metabolisms are set firmly towards growth, they don't have to be concerned with composition yet.

    To summarize, Adults need much greater amounts of protein than infants do. It is scientific fact.

  37. 2:56 Looks like Evolutionary Nutrition is about as sound a 'science' as Evolutionary Psychology (which is also a load of horse crap.) It's amazing how many 'scientists' can invent imaginary cavemen scenarios to support whatever modern cultural bias they have.

  38. So according to video (Gregor), 180 lb person needs 70 grams protein per day.  I've eaten vegan, and 70 grams protein from vegan food is not easy.  

    Plus he doesn't tell you that as people get older i.e. 60s+, they tend to lose muscle mass and a little more protein is helpful for this.

  39. So here I am on my sunny vacation, eating my oatmeal + berries + banana + nuts/seeds bowl on my balcony.

    And then: "fecal transplant studies suggested……"

  40. Most adults need between 45 and 55 grams of protein per day. That is it. I heard somebody talking in my dietician course that this one girl said her daily requirements were 85 gram of protein per day. I'm like "WTF?" That's insanity! Americans are so stupid. I'm ashamed to be American.

  41. .8 gram per kilogram is adequate IF and ONLY IF The PER of the protein is near one which it is for eggs, meat or soy. Most plant food has a PER of .77 and that doesn't even consider the lysine requirement. Your best bet is to calculate your lysine requirement and every other amino acid falls in place. If based on ideal weight you need 60 gram of protein (using .8 grams per kilogram) you'd need near 80 gram of plant protein other than soy to get the minimum required lysine as well as an effective 60 gram of protein if based on a PER of one.

  42. Question: Mainstream science seems to suggest that humans' brains grew in size and intelligence once we could cook meat, hence, making it easier to digest and release its nutrients more easily, allowing our bodies and brains to evolve to their present state. Without the protein in animal meat (and being able to cook that meat), how did we evolve to becoming such adroit, resilient, intelligent beings?

  43. People need to realize that pure sugar might not be best for you, but if they think thats bad, why don't they stay away from oil? how about protein powder? They are the same thing of a different macronutrient. unnecessary and not good for you! Whole foods is the best, most balanced natural way 😀

  44. I would rather go by the percentage of protein calories in my food. Human breast milk is about 2% of the total calories, sounds right for humans. If you go by the RDA then I would be consuming 100 grams of protein a day, forget that if I want to keep my kidneys and bones as I try to gracefully age, 100 grams would be crazy. The FDA's recommendations have been industry skewed from the beginning.

  45. a 3kg baby should eat 550gr of milk a day, about 5,5 gr of protein , which is about 2g of protein per kg of lean mass (maybe a little more) ….. thats a lot of protein of high quality .. we need to see things in prospective …

  46. Let's talk about the failures of veganism
      1st of all modern fruits are full of sugars, totally unlike their ancient ancestors which were small almost bitter and only ripened for about a month of the year vs modern fruit which available 24/7/365 which is not natural
      2. vegan diets are typically deficient in healthy ratios of fats/proteins/carbs
       3. Most vegans look like they never lifted anything heavier than a potato
       4. hormonal imbalances tend to occur in female bodies
      5. altough young, active growing bodies can tolerate high carbs older less active bodies do less well on high carbs
    6. Vegans seem to think that plants like to be eaten. No No No! All plants contain a variety of toxic substances to discourage their being eaten. DYK that caffeine is actually an insecticide? DYK most veggies, especially the leafy ones, contain oxalates which can contribute to kidney stones? DYK that juicing increases n concentrates these toxic substances? "Oh no whee-ohh we're saving the planet aren't we"😭
    7.There's too much more to mention here…

  47. If one is to accept the percentage of protein in human breast milk as the percentage of protein adults should consume, what about the percentage of fat in human breast milk? Is that also the suggested amount for adults? Probably not because it would go against low fat vegan beliefs. In other other words, just because specific percentages of protein and fat are adequate for a baby, one can't extrapolate that those same percentages are ideal for adults.

  48. This channel is obviously not for people that are very active in the gym as well as lead an active lifestyle. I subscribed last week and now unsubscribing. This is very bad advice for anyone that incorporates resistance training into their exercise routine. If you're a couch potato…maybe not. I would suggest Rhonda Patrick if you are a very active person.

  49. Using an human infant is not predictive for an adult human. If this were so and a basis for recommendations then adults should consume the majority of their calories from fat. I am sure Dr. Greger would say ..no whey.

  50. At what age does our brain grow fastest ? Before the Age of One while breast feeding on Mother's milk which has the least amount of PROTEIN of all mammals ! So if you want to have a big brain, don't eat protein. Eat Carbs (7% of milk is carb) and fat (3-5% is fat) and water (>90% is water).

  51. Taking in more than the RDA recommendations will NOT harm the kidneys or liver in people with normal functioning organs. Please anybody find me 1 Study that demonstrate this, that protein will be the sole cause. I bet nobody will be able to find it

  52. I tried a "low" protein diet (0.5 grams per lbs) while I was weightlifting for many hours per week and the effects on my body were horrifying. After increase the amount of protein I was consuming my body and my energy rapidly improved.I guess everyone is different.

  53. I hear lots of people making claims that they run out of energy if they don't eat enough protein, and they carry protein bars with them to avoid fatigue….that never really made sense to me, but the number of people who swear by that is large. As far as an athlete's need for protein, the claims made seem way too high. One thing to keep in mind with athletes is that even those who are doing extreme workouts for maximum gains in muscle, they can only add about a thimble full of muscle per day on their entire bodies. That is not very much protein, because most of that added muscle is water. The idea seems to be, that if you don't have very high levels of amino acids from food in your blood 24/7, then you will not be able to achieve maximum gains in the shortest time. Of course, performance enhancing drugs can dramatically increase the protein utilized for building tissue and that would increase the body's need for protein. In either case, it seems unhealthful, or even dangerous, long term.

  54. They need to recalculate again – and learn that humans, just like all plants and animals, and microbes – MAKE THEIR OWN PROTEINS AND AMINO ACIDS. We are no different as a species.

  55. Doc got the math off…"Ideal weight in pounds times 4 divide by 10" it should be "ideal weight in kilograms times 4 divide by 10"…Also, Ideal weight? How do I get my ideal weight, is that based on BMI non-overweight range of weights for my height?

  56. 3:30 that's why women are told to drink "milk" during pregnancy and later feed the babies "more milk" and meats…

    and they get upset if they can't afford to buy "milk" and meats to be smart and healthy?!

    amusing at best…

  57. Way to generalized –  a large body of new evidence, the International PROT-AGE Study Group [3] and European Society for Clinical Nutrition and Metabolism (ESPEN) [11] concluded that daily protein requirement of healthy individuals over 65 years is 1.0–1.2 g protein/kg/bw. A further increase is recommended for individuals with acute or chronic illnesses (1.2–1.5 g protein/kg/bw) and severe illnesses, injuries, or malnutrition (2.0 protein g/kg/bw) [3,11]. Although these new recommendations have been formulated for adults >65 years, this is only an agreed conceptual cut-off point. Since it has been estimated that 0.5–1% of muscle mass is lost annually from the age of 50 [36], an increased dietary protein intake may be required earlier in life in order to mitigate the muscle ageing process. One of the longest (14-week) interventional studies to date revealed that in adults aged 55–77, ingestion of 0.8 g protein/kg/bw was associated with decreased mid-thigh muscle area and decreased urinary nitrogen excretion (when compared to the second week of the intervention), suggesting that the current RDA might be below the actual requirements of an ageing adult [9]. The link between protein consumption at the RDA level and adverse health outcomes was also confirmed in longitudinal observational studies. As discovered by Houston and others [37], older adults (70–79 years) whose daily protein intake was 1.1 ± 0.4 g/kg/bw had lost 40% less lean body mass over the course of three years than those who consumed 0.8 ± 0.3 g/kg/bw. In summary, protein requirements vary on an individual basis and depend on various factors, such as age, health status and PAL. These factors are not reflected in current recommendations for the general population. Therefore, an increase in intake of dietary protein beginning around midlife merits further research

  58. It's stupid to think human breast milk is perfect food, its perfect only for babies up to 6 to 12 months. The amount of protein that people need is changing during their lives and their source as well. Only in vegan or keto you are ok with 0,8-1 g / kg FFM. And it also depends on whether you are sitting all day or actively doing sports.

  59. Human Brain grows fastest at birth to 1 years of age, fueled only by her mother's milk. How much protein does human milk have that fuels such growth ? LOWEST % of all land mammals including Herbivores. This is Proof that we are Herbivores.

  60. This is gold! Thanks for doing the research and posting!! Bottom line, there simply can be too much of a good thing.

  61. Here’s the facts:

    Animal foods are superior sources of protein. It’s not even close. No matter what metric you use (Net Protein Utilization (NPU), Protein Efficiency Ratio (PER), Protein Digestibility (PD). etc), animal protein is more complete and more bioavailable.
    Animal products have additional nutrients unique to animals that plants lack – but we really need to thrive. DHA, EPA, B12, D3, K2, Heme Iron, Retinol (true vitamin A) to name a few.
    Plant sources of protein often come with carbohydrates (beans, legumes). So you end up consuming a large amount of carbohydrate and fiber just to meet your basic needs. For most people this is too much fiber and carbohydrate. Conversely, nuts are so high in fat (calories) that you’d have to allocate your entire calorie budget to nuts to use them as a main protein source. Tofu is the only plant source of protein that kind of mimics the macro nutrient advantages of meat and eggs – mostly protein and fat, low carb.
    Plant sources of protein also contain anti nutrients such as oxalates, phytates and lectins. These are poisons created by plants to protect themselves. They’re designed to irritate the stomachs and guts of animals and insects that eat them. Plants don’t want to be eaten. This is their defense. So plants need to be prepared properly to reduce or remove those anti nutrients – but you can’t get them all no matter how well you prepare. People with IBS, SIBO, candida, leaky gut, Crohns, and other autoimmune diseases really need to be careful with plant foods and carbohydrates. Unfortunately, this is an ever growing segment of our population, especially among vegans.
    Animal products, such as meat are hypoallergenic. They contain no anti-nutrients or fiber to irritate the gut or block the absorption of minerals. They are easily and fully digestible.

    This is why plant matter is not considered a serious source of protein. It can help prevent overt signs of protein deficiency, but it’s not an optimal choice.

    Literally every culture in the world has always known this just from generations of trial and error. When you are recovering from injury or illness, when you are feeling ruin down, if you are pregnant – basically any condition that requires optimal nutrition – animal products (milk, meat, eggs, organs, etc) are always the most coveted and prized foods. And for good reason – they are superior across the board.

  62. I can feel protein deficiency for several days every time I exercise and don't take my protein shakes. It's called sore muscles and slow regeneration.

    How come almost everybody, who doesn't consider protein to be important, has either a low muscle mass (like Dr Greger? :)) or a high body fat percentage?

  63. Excellent ! The argument of human breast milk is such a blow to the protein centric culture that we have devloppedin the west and that is detrimental not only to us but to the environment as it encourages the consumption of meat .

  64. u know when u have a protein deficiency if u crave meat or cant get satiated from plants
    as well as ur arms will feel weak, ur movements become slower and ur eye lids look like u want to sleep
