Just because vegetables, lentils or nuts contain protein it doesn't mean it's the same/equivalent to the protein in an animal product.
Meat is actually super easy for humans to digest and it has no downsides to it. All vegetables on the other side contain plenty of anti-nutrients such as folate and oxalates.
Everything in human body, skin, connective tissues, tendons, hair, nails, muscles is essentially built out of protein and collagen. Fats are essential for hormone function.
Ruminant meat is absolutely one of the best bioavailable forms of a mostly complete amino acid profile, though eggs and dairy is more complete with differing ratios depending on form/feed.
As to lentils, tofu, chickpeas etc. They're fine for most people in moderation, but they are also relatively inflammatory and plenty of people have digestive issues and allergies to legumes (I do), soy is one of the top 10 allergens that people face. While almost nobody is allergic to ruminant meat.
Similarly, it's a "complete" protein, whereas most vegetables and legumes are missing necessary amino acids.
The downside of beef isn't the "density" of nutrients: the downside is high saturated fat. Chicken breast, though, is similarly high in protein without the saturated fat downside.
I guess I'd challenge the 'no downsides' claim. Few people stick to super lean grass-fed cuts, and the picture on the site is even a ribeye steak :P
The protein density (g/kcal) of a ribeye steak is basically the same as tofu (I think like 14g/100kcal vs 11g/100kcal in tofu)
I know I'm moving the goal posts slightly (I admit I didn't know about bio availability, and see now that I have more to read up on e.g. Broccoli), but am learning as I discuss rather than arguing a fixed point.
I usually suggest around 0.5g fat to 1g protein as a minimal, higher if keto/carnivore.
There are other downsides to beef .. such as the batshit crazy use of ecosystems and resources required to produce it at industrial scale.
Got a (beef) cow roaming in your yard, somehow getting by on whatever grows out of the ground? Enjoy your steak! Generating 6x the calories via a water-intensive cover crop to feed the cow so you can eat it later? Just say no.
So the problem with steak isn't the steak itself it's the "steak dinner" where the meat comes with sides such as french fries and drinks such as beer.
The sound you are hearing is vegan heads exploding.
It was definitely eye opening on the sort of ancient benefit of meat. It's really hard to reach your muscular potential without it.
Red meat has been linked to cardiovascular disease https://academic.oup.com/eurheartj/article/44/28/2626/718873... https://www.tandfonline.com/doi/full/10.1080/10408398.2021.1... etc
In moderate amounts, sure. But frequently eating red meat (more than two or three servings a week) is terrible for you. There's "a clear link between high intake of red and processed meats and a higher risk for heart disease, cancer, diabetes, and premature death": https://www.health.harvard.edu/staying-healthy/whats-the-bee...
- Canned, drained and rinsed: 7g protein / 100g [1]
- Boiled: 9g protein / 100g [2]
Not sure what explains the discrepancy (though the second number is much older), but both are considerably higher than what your can says. Sure you aren't reading a per-serving amount?

To quote famed businessman and philosopher Eugene Krabs: "Money."
I can see why you would expect something like that from this administration, but surprisingly the linked webpage seems to be based in fact.
Broccoli are not an excellent protein source from a dietary perspective.
The question is if I'm preparing a meal that I want to be filling, healthy, and energizing, how should I do it. Broccoli isn't a good answer to the protein part of that question.
And of course broccoli and legumes doesn't have a lobby group, do they?
I guess one way to solve the elderly entitlement crisis is if we all just start dropping dead from heart attacks.
So funny to see people reflexively defend those things being left off because it confirms their own beliefs. A deeper inspection of the actual guidelines has them being very fair to plant proteins:
> Consume a variety of protein foods from animal sources, including eggs, poultry, seafood, and red meat, as well as a variety of plant-sourced protein foods, including beans, peas, lentils, legumes, nuts, seeds, and soy.
The thing is... the pyramid is just a graphic, the actual words give more context.
Are you abusing "dense" to mean calories over calories, rather than the expected calories over weight measure? Even a cursory search shows the latter to be untrue. The former is disingenuous, because despite "density", people do not eat kilograms of broccoli daily to hit minimum-viable protein targets.
In terms of value meat is far more important than vegetables unless I am missing something?
In practice, there's no evidence of amino acid deficiency in vegans/vegetarians except ones that restrict even further (potato diet, fruitarians, etc) https://pmc.ncbi.nlm.nih.gov/articles/PMC6893534/
Besides the ever-popular soybean being a complete protein, if you have normal variety in your diet, it's just not something you have to worry about.
Since we're talking about the actual wording of the report, it admitted the significance of previous reports deciding to order plant foods before animal products. That is reversed in this most recent report, and very intentionally, which they make clear. They also pretend that the health effects of saturated fat intake are still fuzzy, as if the evidence doesn't heavily point towards it being detrimental.
If anyone is holding to unshakeable beliefs and unwilling to consider evidence, it's the shoddy scientists (many with meat-industry related conflicting interests) that wrote the report.
People just don't want to actually put in the effort to prepare it.
You can challenge beliefs and do a modicum of research, which would easily disprove this false and frankly ridiculous notion, which defies even a rudimentary understanding of plant biology.
This is just blatantly and hilariously false.
They are literally called "essential amino acids".
A plant would not survive if it lacked amino acids which are essential.
It it shocking anyone would deny this obvious and extremely basic fact about biology.
Per calorie beef and broccoli are actually surprisingly similar, but broccoli comes with fiber, calcium and vitamin C, while beef comes with saturated fat.
Of course, broccoli is not very calorie dense, so you would need to eat a lot.
More realistically, tofu, which has about as much protein per calorie (and almost as much per gram) as middling lean beef. But has half the saturated fat, more iron, more calcium, and fibre.
You just get more good stuff, and less bad stuff with veg.
There are plenty of lactose intolerant people. These people can meet their nutritional needs without dairy. (For Calcium: via Sardines, leafy greens, Tofu, etc.)
AGEs are also present in vegetables and legumes, but certain meats like bacon contain unbelievable amounts relative to other foods. (Interestingly: Rice contains almost no AGE's.)

Milk can help in regions with dietary low calories, but is mediocre or bad for fat US citizens.
I also found the food shown very misleading.
they're called essential because humans cannot produce them internally, so we have to consume them (though you could in principle make the same assessment for other animal species, but that's less relevant, unless you're, I don't know, raising cows?)
plants don't eat, but produce organic molecules from raw ingredients (or almost raw, in case of nitrogen), and can produce all amino acids - but in different quantities, so maybe the (parts of) plants you eat don't have all the necessary amino acids.
Unprocessed meat is what humans what have been eating for hundreds of thousand of years.
Meat products are commercial new inventions and contain stuff like preservatives, volume expanders, flavor enhancers and coloring agents. They also typically contain added sugars, sodium, malto dextrin, corn syrup.
One can't seriously put these together and call them the same, make a study where participants might be eating SPAM and then conclude that "red meat is bad".
Given the choice between "Domino's vegetarian pizza", "IKEAs meatballs" and "steak that is fried,salted and peppered" which one do you think will be the healthiest option?
"We put a bunch of meat derived products with high amounts of artificial additives together with actual meat and then concluded that meat is the problem"
Agree that g/kcal isn't perfect but g/g has its own corner cases like water content skewing things badly (e.g. dried spirulina is 57% protein by weight but you'd never eat more than like a gram in a serving). I never meant to suggest that people should be eating broccoli _in place of_ turkey, only that by _de-emphasising_ the protein content of many vegetables in favor of animal proteins, the graphic encourages meal planning that must always contain an animal protein. More insidiously, in my experience at least, it blurs the line between the nutrition content of different animal proteins ("I have my veg I just need 'a protein' now") which leads to more consumption of red meat regardless of quality.
The graphic that I wish someone would make is the 'periodic table of macro nutrients' that positions foods along multiple dimensions at once but I don't know how you would actually do it in just two dimensions.
Possibly because those foods are culturally un-American or something silly like that
> The DGAs recommend a variety of animal source protein foods (ASPFs) and plant source protein foods (PSPFs) to provide enough total protein to satisfy the minimum requirements set at the Recommended Dietary Allowance (RDA) of 0.8 g/kg body weight for adults and to ensure the dietary patterns meet most nutrient needs [3, 4]. However, over the past 20 years, an extensive body of research has underscored the unique and diverse metabolic roles of protein, and now there is compelling evidence that consuming additional foods that provide protein at quantities above the RDA may be a key dietary strategy to combat obesity in the U.S (while staying within calorie limits by reducing nutrient-poor carbohydrate foods). Instead of incorporating this approach, the past iterations of the DGAs have eroded daily protein quantity by shifting protein recommendations to PSPFs, including beans, peas, and lentils, while reducing and/or de-emphasizing intakes of ASPFs, including meats, poultry, and eggs. The shift towards PSPFs was intended to reduce adiposity and risks of chronic diseases but was primarily informed by epidemiological evidence on The Scientific Foundation for the Dietary Guidelines for Americans, 2025–2030: Appendices | 350 dietary patterns, even in some cases when experimental evidence from randomized controlled trials (RCTs) was available to more specifically inform this recommendation. Another key aspect that DGA committees have inadequately considered are the nutrient consequences when shifting from ASPFs to PSPFs. ASPFs not only provide EAAs, they also provide a substantial amount of highly bioavailable essential micronutrients that are under-consumed. Encouraging Americans to move away from these foods may further compromise the nutrient inadequacies already impacting many in the U.S., especially our young people. Compounding this is the recent evidence highlighting the fallacies of using the unsubstantiated concept of protein ounce equivalents within food pattern (substitution) modeling, leading to recommended reductions in daily protein intakes and protein quality since ASPFs and PSPFs are not equivalent in terms of total protein or EAA density. Given that 1) there is no Tolerable Upper Intake Level (UL) for dietary protein established by the Dietary Reference Intakes (DRIs) and 2) consuming high quality ASPFs above current recommendations has shown no negative health risks in high quality RCTs, it’s unclear as to why previous DGAs encouraged shifts in protein intake towards limiting high quality, nutrient dense ASPFs. It's essential to evaluate the evidence to establish a healthy range of protein intake and to substantiate whether or not limiting ASPFs is warranted and/or has unintended consequences. An alternative approach that may be more strongly supported by the totality of evidence is the replacement of refined grains with PSPFs like beans, peas, and lentils. Given their nutrient dense profile (e.g., excellent source of fiber, complex carbohydrates, & folate, etc.; good source of protein) nutrient dense PSPFs complement but do not replace the nutrients provided in ASPFs (i.e., excellent source of protein, vit B12, zinc, good source of heme iron, etc.). By including high quality, nutrient dense ASPFs as the primary source of protein, followed by nutrient dense PSPFs as a replacement for nutrient-poor refined grains, a higher-protein, lower-carbohydrate dietary pattern can be achieved which likely improves nutrient adequacy, weight management, and overall health. -- https://cdn.realfood.gov/Scientific%20Report%20Appendices.pd... Appendix 4.9
At 23g/100g, lean beef has a very high protein/weight ratio. Similar to chicken and turkey breast and exceeded only by canned tuna and processed protein isolates like soy protein isolate, whey protein isolate, and wheat gluten. For comparison, protein content of firm tofu, lentils, and chickpeas is much lower, at 14g/100g, 9g/100g, and 8.5g/100g, respectively. They all contain a lot more carbs per 100g than lean beef.
Further, lean beef contains a full and balanced amino acid profile, which lentils, tofu, chickpeas, soy protein isolate, and wheat gluten does not. It's an excellent food. However there is evidence that charred red meat and red meat containing nitrites is associated with a slight increase in colorectal cancer, so people should be consuming minimally processed red meat where possible, as per the guidance.
The original commenter is simply misinformed about them excluding plant based protein. That is what his comment was shows.
That is not what your linked article says. It says there is not evidence of protein deficiency, and the deficiency of amino acids is overstated. Not that there is no deficiency.
And vegan/vegetarian health is really a 2nd order variable here. Vegans and vegetarians could have massive amino acid surpluses and it remains a fact that vegetable proteins lack useful amino acids that meat has. Maybe the vegetarians are eating lots of eggs. Maybe they are taking lots of supplements. Maybe they are actually eating meat despite calling themselves vegans and vegetarians. It doesn't matter. There really is no disputing the fact about the composition of meat/vegetable protein.
The quality of a protein is measured using PDCAAS (Protein digestibility corrected amino acid score). It's a score between 0 and 1 that measures the quality of a protein as a function of digestibility and how well it meets the human amino acid requirements.
It is indeed correct that both lentils and chickpeas (which the original comment you replied to was talking about) have a much lower PDCAAS value of around 0.70. Data on beef varies, but it is generally considered to be a complete protein with a PDCAAS score above 0.90.
Instead of accusing "people who insist on eating animals" of lacking scientific knowledge, it would have been much more helpful to point out that the highest quality proteins on the PDCAAS scale are almost universally vegetarian or vegan: eggs, milk, soy, and mycoprotein all have higher scores than beef, chicken, or pork.
This isn't a problem since you only need nine essential amino acids and they are present in adequate quantity in various vegetables and shrooms. The others are synthesized by ones body.
- Chicken: 27/100g
- Beef: 31g/100g
- Hemp: 32g/100g
- Pumpkin: 33g/100g
- Soy: 36g/100g
- Seitan: 75g/100g
Eating only one type of food is not good for your health, whether it is a plant or animal product.
It's not a problem for saucy dishes like a curry, but even experimenting with friends and borderline "molecular cuisine" techniques I have never once managed to flavour tofu itself :(
Not in the quantities we eat of unprocessed meat these days.
The buffoonery continues. These irrational statements are straight out of the meat industry playbook - of course again lacking in any credible citations. And all you had to do was spend even 5 seconds reading a public encyclopedia to avoid this embarassment https://en.wikipedia.org/wiki/Phytoestrogen#Effects_on_human...
