Some protein is obviously desirable, but the ratios, like anything else in chemistry/biology, are paramount.
I don't think the USA has a problem with under consumption of meat and dairy. If anything, it has a long standing overconsumption problem.
You're right that ratios matter enormously, but optimal ratios vary significantly by individual - genetics, activity level, metabolic health, and existing conditions all play roles. The overconsumption concern is valid for processed meats and in the context of sedentary lifestyles with excess calories, but the picture is less clear for whole-food animal proteins in balanced diets.
The real issue might be less about meat/dairy per se and more about displacement of other beneficial foods (fiber, polyphenols, etc) and overall dietary patterns. Many Americans do overconsume calories generally, but some subpopulations (elderly, athletes, those on restricted diets) may actually benefit from more protein.
because we have teeth specifically designed to get meat off bones and animals that don't eat meat and weren't "designed to" don't have teeth designed to clean meat off bones. and that's just one i came up with, off the cuff.
if it's current farming practices that make the meat/dairy bad for us, then fix that. But i don't currently believe there's a greater health benefit to taking a ton of supplements to replace the missing nutrients that meat and dairy give us that you absolutely cannot get from vegan diets without it becoming a monotonous pain in the neck.
Not all meats are inflammatory. Processed and high temp cooked meats especially red are.
And I don't think we have the answer fully to why, but we know the lesser processed it is the better, and I believe I've seen some things about grass fed and all these more organically/traditional made meats seem to not be as inflammatory.
Also, we evolved during a period where we hunted, so even the idea of farmed meet maybe isn't really part of our evolution. But also, during our hunting evolution, we likely didn't have meat at every meals. Plus if you ever had game meat, it tastes really different and often isn't as good as what we farmed. So we kind of came to farm what tasted the best and was easy to farm, so it might be those meats aren't as good for us.
Also, you can't always assume that the environment we evolved in and the "natural" state is good for us. It wasn't bad enough for us to dwindle in numbers, but our population count was kept much lower than now and our life expectancies were shorter. As long as we made it to a healthy reproduction state evolution doesn't care. So all these inflammatory issues appear starting in your 30s and really become a problem much later in life. It's possible this didn't matter in evolutionary terms.
Lastly, you also have to take into context what else we'd do/eat. If our diets were more balanced than other things we would eat could neutralize some of that inflammation and meat has other vitamins and nutrients that are benefitial, but if someone cuts those other things out of their diet now the inflammation could become a problem.
So it's all more nuanced and complex.
Also, human ‘canines’ are pretty pathetic. They’ll do the job in getting meat off bones, sure, but are nothing compared with my dog’s teeth – he has proper canines. (He also doesn’t have to prepare and cook meat before tucking in. Humans are actually pretty lame meat eaters even in comparison to other omnivores like dogs, let alone carnivores like lions.)
But also, I've seen people often assume vegetarian or vegan diets are "healthy". But many people in India for example will still eat a lot of refined carbs, added sugars, fat heavy deep fried foods, large volumes of ghee or seed oils, etc. And total avoidance of animal products can also mean you have some deficiencies in nutrients that can be hard to obtain otherwise.
A plant-forward diet is more specific, like the Mediterranean diet, which itself isn't at all how your average Mediterranean person eats haha. But it involves no processed foods, no added sugar or excessive sugar, diverse set of nutrients by eating a balance of veggies, legumes, nuts, seeds, meats, dairy, fish, and so on all in appropriate proportions, as well as keeping overall caloric intake relatively low.
It's quite hard to eat that way to be honest haha.
The saturated fat → LDL-C → heart disease relationship has a lot of evidence and history behind it. A very interesting research project if you needed one. I call this advisory a "downgrade" because heart attack and stroke (among other conditions) are both: 1) downstream of saturated fat consumption, and 2) the most prevalent causes of death among people in the developed world.
fish > poultry > red meat. (Fish and poultry can be swapped, mercury is a real problem).
But really if you are looking for the healthiest proteins then you really can't do much better than nuts and beans.
Red meat beyond having a lot of links to heart disease is also linked to cancer. It should be seen as a treat, not the main thing you should be consuming.
Ever look at Mongolian cuisine? That's the bulk of what they eat. Most of those guys seem pretty healthy to me.
Meat (non-processed, no sugary sauce or gravy), and dairy (plain, fermented, no added sugar). Those are kind of "neutral" foods. If that's all you eat, meaning you don't eat any crap, you're much better off health wise than if you eat crap and try to also eat a bunch of veggies, fish, fruits, legumes, etc.
There's nothing absurd about this at all, this is my diet and my LDL numbers are great.
