[@stevetiger73]

Great video. The only criticism I have or maybe it's my lack of understanding is that I have no idea why you state to increase protein requirements above .8 gm per kg. Maybe I've missed something here. It'd be great to help me out here. Is there any valid science to state this point ?

[@KennyPowers-cr5tc]

We all know you're a liar Simon... There isn't a single study on earth showing the more carbs you eat and the less animals the better, not one! But there is evidence that a vegan diet, which foods are inferior in protein, calcium, zinc, iron, B12, K2, vit D etc.. there is evidence vegan is harmful ESPECIALLY to children who end up smaller and have lower bone mineral content. Not to mention a super high carb diet leads to CVD. Meat is superior for human development of the brain, muscles, skeleton for performance, recovery and longevity. This is why vegans/vegetarians have to compare their diets to the average American diet.. because that's all they can because diets with a mix of beef, turkey, chicken, salmon, quails, eggs, kefir etc alongside low-moderate carbs is superior.

Here the title says it all. " Dietary protein intake in midlife in relation to healthy aging - results from the prospective Nurses’ Health Study cohort Andres V Ardisson Korat M Kyla Shea Paul F Jacques A Heather Eliassen Walter C Willett Qi Sun All together now what does that say..midlife. Plant chompers and all the rest will be applying this within the overall context of for all, not the elderly. Who do you think will watch plant chompers with great interest, some young buck or as the author of that is .elderly, who?. The young buck will be watching sports based nutritional content, typically if they are interested in nutrition at all. Oldsters will be watching plant chompers by demographic study. I have not done one but can say that with confidence, a older viewing group. Look at the guy...what do you see? The elderly have specific protein requitements above that of a mid life person if they resistance train or are very active. This specific has been addressed in study. It is as per example the study of longevity itself. What is the longevity expected af a american child at age one as opposed to the life expectancy of a average american 70 year old? The one year old will top out at below 80 the seventy years old will be found above 80. Longevity study is a function of what...age. So study groups in longevity are defined by what...age groupings. You must specify midlife if you are to verse on the topic. Not one diet is proven best for all, and not all protein requirements are best for all age groups.Protein requirements you and I both know, differ significantly as attributable to assimilation capacity in variance with age. I am not disputing your overall consideration plant verses animal, but this must be stated. Dairy some conditions of cancer it is theorized are protective by dairy. That suggested by seventh day study results. Women do better than men longevity considered, and vegan woman live longest of all, but not vegan men.. Vegan men do not live longest under study of men only in consideration. So it gets quite specific as to gender and also as mentioned age. One addition worth noting we suffer different cancer types by gender as life ending events.

[@SibolSensei]

@@TheProofWithSimonHill I wish the study separated out fish protein, considering Valter Longo seems to suggest mostly vegetables with occasional fish seems to be optimal. Maybe that's wrong or maybe that's right, but I don't understand why there's not a closer look at fish protein vs other proteins.

What do isn't clear to me is the level of exercise this cohort typically did and whether that would impact the results in any way. My wife is a nurse of 40+ years, my daughter is a nurse of 15 years and i worked in the NHS for 20 years. We know and have known so many nurses over the years and is there is one commonality amongst them all, especially that particular age group, is that exercise, particularly resistance exercise, was never prevalent amongst them. Indeed, the vast majority did zero "exercise" whatsoever. Would an "exercise-heavy" cohort have the same results with the same dietary intakes?

[@TheProofWithSimonHill]

Glad you’re doing better! I will say, many people following omnivore diets develop auto immune conditions too. Cause of these conditions is not really well understood. It’s difficult to pin down any diet or food as the culprit. Lastly, this video was not about a vegan diet and the msg wasn’t everyone should adopt a vegan diet.

[@cynthiabroze]

I’ve been a subject in the nurses study since 1989-Harvard’s second group. This was probably the first group that started in 1976. They collect a variety of information from us, every few years, because they think nurses are better at keeping records. I’m not sure we are a healthier group…lots of junk and fatty food in the break rooms. Long stressful work hours do not equal healthy eating for most.

@@TheProofWithSimonHill In 2023, Food and Agriculture Organization of the United Nations published a document named "Contribution of terrestrial animal source food to healthy diets for improved nutrition and health outcomes". Will it be possible for you to review it and make a video on it? There are many claims in that document: i. "A robust evidence base shows that milk and dairy consumption during pregnancy increases infant weight at birth and may also increase birth length and foetal head circumference" ii. "Evidence shows that consumption of milk and dairy products by school-age children and adolescents increases height and reduces overweight and obesity. Beef consumption in this life-course phase has been shown to improve cognitive outcomes." iii. "In adults, findings largely indicate that eating milk and dairy products, specifically yoghurt, has positive effects in terms of reducing risk of all-cause mortality, hypertension, stroke, type 2 diabetes, colorectal cancer, breast cancer, obesity, osteoporosis and fractures." iii. "A fairly strong evidence-base shows that lean red meat consumption has positive effects on muscle health. Other evidence suggests that milk and dairy products and other TASFs have a potential role in mitigating sarcopenia (muscle loss), fractures, frailty, dementia and Alzheimer’s disease."

Thank you, Simon, for this excellent analysis, and for not making this about personalities. As I have listened to you for some time now, it seems that you try to stay with the evidence, and not the perspective as a vegan. I have been vegan for years, yet I like to listen to folks like Layne who are not vegan. He is smart and focuses on science, yet he has a blind side. When I listened to his podcast on this, in my opinion, he kinda glossed over the results of the results of plant-based protein. I hope he watches your podcast and connects with you in the future. You have had some interesting conversations with him online, that have had considerable agreement. May that continue to be so. And may you continue to be an unbiased (as much as possible) source of honest plant-based and scientific wisdom.

Thanks for the review Simon, very thorough, always good to hear more positions on the protein question. Although, Nurses Health Study, prospective epidemiology using food frequency questionnaires... quite poor data no matter how much you control / adjust for confounders. Recent mendellian randomisations, RCTs and systematic reviews using GRACE method show no associated with animal foods / red meat with many diseases.

[@michael052]

Stipulating the results of the study are correct, how do we know if we have a positive effect "plant protein" vs a positive effect of "plants"? - the presence of the protein in the whole-food matrix of the plant. In other words: (a) If we supplement the animal protein with compounds from plants and healthy dairy such as fiber, polyphenols, fermentation pre/post-biotics, etc., do we see the same benefits as moving to more plant-forward protein sources? (b) If we supplement the plant group with additional leucine or saturated fat, do we see any reduction in benefits? We could also consider adding antinutrient compounds like neu5gc to the plant group, or lectins/oxalates to the animal group. If "replacing 3% energy from animal to plant protein increases odds of healthy aging by 38%" (which would only be a small total shift in amino acid profile of total energy), then ISTM that it less likely the protein composition itself, and more likely beneficial compounds in the plants or fermented dairy. [edit]: Although now that I'm catching up to "The main plant protein sources were bread, vegetables, fruits, pizza, cereal, baked items, mashed potatoes, nuts, beans, peanut butter, and pasta.", it seems like there were really not a lot of beneficial plant compounds consumed.

[@demonfedor3748]

When I saw the data on the screen I went right for p values and hazard ratios which immediately stuck out for plant protein. Knowing how to read studies and actually reading them makes a real difference compared to not knowing how and not properly reading them.

[@rahvastepaabel]

Plant protein is 30% antinutrients that won’t absorb and wont lete other minerals like zinc absorb as effectively. Plants proteins are deficiant in many amino acids, especially leucine which triggers anabolism.

[@demonfedor3748]

@@rahvastepaabel Plant protein has nothing to do with anti-nutrients. Certain plants may have some anti-nutrients same as certain animal products ( like eggs). And we have developed methods to almost eliminate them like soaking, boiling, germination and fermentation. Multiple studies have shown better health outcomes with plant protein compared to animal ones regardless of anti-nutrients. Also plant protein has all 9 essential amino acids,just maybe a bit smaller than in animal protein, same for leucine . Soy protein is highest quality plant protein both rich in leucine and safe for health with 80 percent overall quality compared to whey.

[@samanthabrown5180]

The assumption that nurses are more health conscious than general population is not true. The challenges they face from working shift patterns (interesting if they adjusted for the impact of shift patterns). When working with clients I collect diet diaries months apart to make sure the client is staying on track, what the client thinks they’re eating to what they’re are actually eating is vast. And finally when they say I’m eating chicken they mean the chicken in a pre packed sandwich together with a packet of crisps and a can of fizzy pop. So while the animal protein may not be classed a red or processed, it contains lots of sugar and additives for shelf life. While the study is the best we have at the moment it is far from looking at good quality animal proteins.

[@yvonne3903]

i don`t think this is the best study to look at whether Simon's recommendation of protein is health promoting or not. there is a plethora of data in the literature however. i'm sure that protein intake should differ based on everyone's goals and activity levels. also, the fiber that comes with all the plant protein is definitely the holy graal of the good outcomes achieved with plant protein?

This is definitely a great exploration - I am trying to grapple with the idea that we think it's ok to separate out the effect of e.g. animal protein from the increased fruit & vegetable consumption but we don't feel any need to separate out the effect of fiber inherent in many plant protein sources. Maybe I am missing something but it seems like you can conclude something like -- In isolation, plant protein is superior to other forms of protein because it guarantees an increase in fiber, however, people who are health conscious and eat animal protein + fruits and vegetables get the same benefit. It seems like in one scenario we are willing to take the "package" without pulling apart the constituents, ie plant protein, but in the other "animal protein + f&v" we feel compelled to try to separate it out. I think there have been other studies which stratify based on fiber intake and you see a lot of the "badness" of animal protein go away, often attributed to healthy user bias. EDIT - Was rewatching Layne's video and he actually makes this same point about not controlling for fiber so want to make sure I am not implying anything original here. Just seems like Layne does address this and curious for the response.

I'm in my 70s, and I was raised everything organic. My father would say go out and get our lunch so I'd go outside and pick all the vegetables for our lunch. And we had apple trees. Many other trees and they were never sprayed. We used a method that old farmers use, and that is smoking the trees. We had well water.And I used to work card shoveling the snow and cutting the grass with a pushmower. This wasn't just your front yard or your backyard.I would cut one acre of tall grass. I would say, "You say shovel and clear the snow from the house to the main highway?Which once one quarter of a venezer just wide enough for my dad to get the pickup truck out. I started young picking up large rocks and putting them in the wheelbarrow.As my dad was a carpenter.So at the age of ten, I was working very hard. At 15, I was already sewing my own clothing, doing my own Canning and making my own bread by hand, and my father never had cattle full of hormones. He wouldn't even allow anything in the house that indicated it was with chemicals.. We ate a lot of cheese.And I had a lot of milk. And tons of vegetables. We would go to mcdonald's maybe once a month if that just so I didn't feel left out from the city Kids. I would walk 6 miles almost every day after school to see my friend or on the weekends. When I was in my twenties and thirties, I used to do a lot of outdoor activities. I remember having a backpack.That was at least fifty pounds and walking through a narrow area that was ten miles into the bush to go fishing all day and walking ten miles back with carrying a canoe. My boyfriend would be carrying the carrying the front, and I would be carrying the back. We would always be out somewhere on the weekends. When I was 32 I walked into a gym.The very first time and this guy came up to me and he says boy.Are you ever strong looking?How much can you bench?? I had no idea what he was talking about. I didn't realize I was strong, but I thought maybe I should go to the gym and become stronger. I got over to the bench, and the first ti pushed two fifty. It was two hundred and fifty pounds. I started shaking a little bit, but I knew I could do 275. I really thought nothing about it because I didn't understand if two hundred and fifty pounds were all that great. Lol. Looking back now, at my time in life in my sewendy's.I wish I didn't leave home early. I wish I never ate any junk food in my life. Even though I tried to keep it all together the world seems to push fast foods on to you and a lifestyle that we should never even live and that city life. You can have all this protein and all this food.Sure.It's good and we need it, but we need a life away from the city.We need a life that is stress-free. Which is very hard to do nowadays.

Possible reasons for the negative results in the animal protein group: 1. Didn't eat their protein from lean animal sources. 2. A high percentage of people in this group, perhaps also frequently enjoyed barbecuing their meat sources. 3. The majority of the people in this group, was also less health conscious in their daily lives, when compared directly to the people in the vegan group. Just from the top of my head... That said, I personally have a feeling that plant based food, when eaten correctly, is likely to provide the most benefit if heart health is the primary goal.

Layne Norton. One of the last people I would ever listen to for health advice

[@ChessMasterNate]

I think the biggest problem with animal protein is Advanced Glycation End-products(AGEs) created in the dominant preparation/processing methods used in the US. People often cook meat in ways to bring out flavors produced via the Maillard browning reaction. This reaction creates AGEs. They are the result. However, there are cooking methods that minimize their creation. We can make stew, chili, soup, and other dishes where there is a high level of moisture throughout the cooking process that keeps the temperature reached by all parts of the meat low. If that is a little acidic (without also adding sugar), that's even better. Frying, flame broiling, BBQing, roasting and more, generate copious amounts of these harmful AGEs. They are also created through mechanical blending. Which is why most processed meats have high levels. But many other blended substances also have high AGEs like butter, cream cheese, mayonnaise, and margarine. AGEs are also created by fermentation, so I have to go against Simon's advocation of fermented foods. I know there are studies that show positive results from consuming natto and other stuff, I just suspect that you have beneficial substances along with harmful, but by more careful food selections you won't need those beneficial substances, and have to take the harmful ones with them. As such, I think it only makes sense to eat cheeses with very low fermentation or no fermentation: ricotta, cottage, mozzarella, string (it's just mozzarella). AGEs are strongly liked to heart disease and many other diseases of aging. One in particular you accumulate in your body because even healthy kidneys cannot remove it. This is glucosepane. These AGEs are easily measured in the body using a cuff that uses a frequency of light that causes them to fluoresce. But it is not approved in the US yet. For eggs, boiling is excellent, but scrambling is fine too. Frying an egg is not good. And vegetarians and vegans are not free of risk from AGEs. Roasted nuts and seeds, toasted nut and seed oils, and nut and seed butters are all high in AGEs. Raw pine nuts are still high. Raw cashew are also somewhat high. And you can easily make lots of AGEs using the blender. You want to avoid blending carbohydrates with either protein or fats. People often make the mistake of putting flaxseed in their mostly carb smoothie, or protein in their mostly carb smoothie. These can be in there, they just need to be blended separately and then just stirred together with a spoon. And any kind of frying makes loads of AGEs. AGEs lodge themselves in the proteins structures that the body uses for support. This stiffens these protein structures, increasing risk of ruptures, and hardens the arteries. AGEs are one of the causes of wrinkles on the skin. Crosslinking from radiation and damage to elastin from several causes, are the other main causes.

In all scenarios (total protein, animal protein, plant protein and dairy protein) it seems like reducing MUFA intake will give a benefit. Quite intersitng considering olive oil, avocados and most nuts are pretty high in MUFAs and rather positivley associated with health. Furthermore at 18:16 what is really strange is, that among all things one could swap for plant protein, SFA did still "best". Swapping out SFA for plant protein was associated with the smallest benefit for plant protein. Why are SFAs performing not way worse , but MUFAs did??

[@TheProofWithSimonHill]

Probably because MUFAs are also in a lot of animal foods. Read this paper “MUFAs from plant (P-MUFAs) were reported to be inversely associated with total mortality, whereas MUFAs from animal (A-MUFAs) were associated with higher mortalit” www.ncbi.nlm.nih.gov/pmc/articles/PMC8380819/#:~:text=MUFAs%20from%20plant%20(P%2DMUFAs,(TFAs)%20intake%20on%20mortality.

“ittle and conflicting evidence exists to associate monounsaturated fatty acid (MUFA) intake with risk of mortality. One possible reason is that dietary MUFAs come from both plant- and animal-derived food with divergent dietary components that may have different effects on health outcomes. MUFAs from plant (P-MUFAs) were reported to be inversely associated with total mortality, whereas MUFAs from animal (A-MUFAs) were associated with higher mortality (8). Few epidemiological studies have focused on the effect of trans-fatty acids (TFAs) intake on mortality.”

I am living with an elderly mother (93) who lived with undiagnosed FH for the first 9 decades of her life and did not have her first heart attack until 92. But she is now living an impaired quality of life because of plaques in her coronary arteries (making any exertion difficult) and plaques in her legs, called claudication, that causes "wake-up" pain every night as the muscles and nerves in her legs starve for oxygen.

Great video, Simon! I really appreciate your thorough analysis of the recent Harvard study on protein sources and longevity. I particularly agree with your emphasis on the benefits of plant-based proteins. The study's findings align well with existing research showing that plant-based proteins can reduce inflammation and improve cardiovascular health. Your breakdown of the optimal intake levels was spot on and crucial for those looking to balance their diet without overloading on animal-based sources. One area that I think warrants further exploration is the study's limited focus on the diversity of protein sources within plant-based diets. For example, the potential differences in health impacts between various legumes, nuts, and seeds weren't fully addressed. Additionally, the long-term effects of protein combinations and their impact on the gut microbiome would be an interesting angle to dive deeper into. The study's scope on exercise and its interaction with protein intake could also provide a richer understanding of how diet and physical activity together influence longevity. Another important point to consider is the connection between higher fiber intake and plant proteins versus animal proteins. The increased fiber from plant-based diets could be a significant factor contributing to the health benefits observed, impacting gut health, cholesterol levels, and more. Overall, your insights are incredibly valuable, and I look forward to more content like this! 💪

Glad you think so!

Newbie amateur studies reader: how do researchers take into account any other factor impacting longevity ? How to they separate the effect of let's say the lemon juice or olive oil used in a salad, that positively impact longevity as well ?

In this and most of the papers "Cox proportional hazards models" are used. Then it's up to the researcher and the data what you want and can model. You can separate dressing and vegetables from a salad if you have the data and if you want to. Or you can just assume the composition of an average salad. Or you just use "salad" as a quantity in your model. In general I find the interpretation of data not easy because you have to find out what things like "animal protein", "plant protein" and "MUFA" precisely mean in the model. And that's not reported in the main part of the paper most of the time. If you're lucky it's in the supplementary data. Multidimensional quantities like "plant protein" (i.e. increase plant protein can be archived by doing very different things) in Cox models means more like "typical plant protein". So all the possible plant protein is weighted by more or less how typical their consumption is in the population (it's more complicated). That gives you a one-dimensional quantity comprised of a weighted sum of individual plant protein sources.

Great info! Thank you for your clear and concise interpretation of the study.

Glad you enjoyed it!

So if I need at least 150 grams of protein per day, how can I do that consuming only plant proteins? My gut cannot handle a pound of lentils or broccoli or tofu daily. Theres just no way I can get enough protein via plant sources. Also, there’s more to life than a perfect diet. Genetics play a major role in our outcomes regardless. Just don’t be overweight and exercise a lot and you’ll be just fine even eating lots of animal protein.

"Just don’t be overweight and exercise a lot and you’ll be just fine even eating lots of animal protein." - The study says otherwise

"Maybe he can just tell me to f@#$ off" 😂 Love this video!

[@TheProofWithSimonHill]

Maybe he will! Haha

This is a really good study and your video does an excellent job breaking it down! Thanks for the work! As a next step I'd like to see data that goes into more detail with animal and dairy protein. The reason being that I get most of my protein from animal sources however it is largely from fatty fish like sardines and salmon, fermented dairy (i drink about half a cup almost every day) and some eggs, at most 6 per week. I might eat other types of meat maybe twice a week in a typical week. My impression of the scientific literature is fish and fermented dairy garner a lot of health benefits, so it quid be interesting to see the methods used in this study executed on them, as well as eggs. Maybe that will be done later? Hopefully!

Some great points!
