Of course paleo is absolute BS, so why does it matter?

I don't get why paleo diet is not congruent. So our DNA is build upon iterations(generations), and the aliments that were eaten in the majority of those are better suited for our current generation. Any argument?

The "vast majority" of our ancestors were single cell beings.

This article opens with, "[New science] is also showing us that advocates of trendy paleo and vegan diets are missing the big picture of how our omnivorous digestive system works." But it concludes with, "Pick a modest-sized plate and make meals using vegetables, legumes, leafy greens, beans, fruits, and unmilled whole grains as the main ingredients. Add some meat if you want and dollops of healthy fats on the side o…

Well, the author points out that meat is beneficial, but eat just a small amount with meals so it largely gets absorbed in the small intestine (and he explains why this is important).

The other valuable information is why whole grains are OK to eat (I favor them in small portions only) and processed grains are so bad for us.

Right, so including how close in time were those generations happening(compared to the actual one), then that diet would be still valid?

It's nice to see an article that explains that too much animal protein can be bad for your health, without advocating a 100% plant-based/vegan diet. We humans are apes, and when you look at other apes, they eat mostly plants, but not always only plants. For example, chimpanzees eat small amounts of meat. I'm a bit skeptical to the claim that whole grains is a nearly perfect food, though. Think about it - we apes have…

What? Looking at other apes is a poor indicator. What an animal eats has to do with it's environment and it's digestion mechanisms. Some apes largely ate grasses. Nutrients matters, but largely is solved by eating a varied diet. You might have noticed that we do something other species don't. Cooking! It's a pre-digestion mechanism that saves a lot of work. Combined with our omnivorous digestive system we can probabl…

So, I googled for grass eating apes and found this: https://www.nsf.gov/news/news_summ.jsp?cntn_id=128106

Is this what you were thinking about?

The evidence seems rather sketchy, though. From the article:

"If early humans ate grass-eating insects or large grazing animals like zebras, wildebeest and buffalo, it also would appear they ate C4 grasses.

If they ate fish that ate algae, it would give a false appearance of grass-eating because of the way algae takes up carbonate from water, Cerling says.

If they ate small antelope and rhinos that browsed on C3 leaves, it would appear they ate C3 trees-shrubs."

Seems more likely that they ate the animals, though. I mean, otherwise, shouldn't our teeth have been different by now?

Valid for what? You have no obligation to eat what your ancestors ate. Our ancestors certainly didn't, which is why they didn't eat like single-celled organisms. If what you are thinking were true, it would be true for them as well.

Not to mention the fact that your food has evolved as well.

If anyone else wants a quick summary of what you can find on Google Scholar for this: There is currently no strong evidence in support of the idea that A2 milk has better digestive or other health properties than A1 milk. Most of the stuff I found out there concluded that there was no significant difference, and the few that I found on the rest of the Internet were contradicted elsewhere.

This is correct and does not contradict anything I said. It is quite easy to try it for yourself and see if it does anything. Of course you will want to avoid consuming large amounts of other dairy sources while you are trying it.

In order to build confidence in the results of a personal experiment like this one, it's best to (double-)blind it as much as possible and log lots of concrete data every day (e.g. keep track of your bowel movements, sleep quality, alertness levels, blood pressure, etc). This should help limit the impact of any (conscious or subconscious) preconceptions or other psychosomatic effects.

Also, change as little else in your life as possible while you're performing the experiment to control for confounding variables.

Maybe, but remember that the process of review is removed. Even the most brilliant people quite happily believe dumb things.

Sure. But brilliant people generally don't believe dumb things that in their core area of expertise....

Sure, but a PhD's area of expertise is increasingly narrow.

Sorry for not finding a name, but there's an early hominid (divergent from us, but not an ancestor) that ate C4 grasses and had the jaw shape for it. They are now extinct. Point being that we can't extrapolate from other species (apes) even if we share an ancestor.

Early humans were probably mostly scavengers anyway until fairly close to the agricultural period. Its unlikely they ate much meat.

I didn't say obligation. After reading here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4091895/

My question was an oversimplification.
