I completely agree, and it also appears to change every other decade.
Suddenly, drinking coffee became healthy, eggs stopped being unhealthy and drinking a glass of wine a day became a major risk for CVD.
Engineers are spoiled when it comes disentangeling relationships between causes and effects because our systems are relatively simple compared to the huge and complicated mess that is human (or, indeed, any) biology.
Luckily, fasting does. Whatever your metabolic and inflammation markers are, they will all trend worse after energy input.
If your waking day is 16 hours long, reducing your "feeding window" by even four hours increases your time spent in "low inflammation mode" by 50%.
Looking for a drug or a novel intervention is silly when you haven't picked even the lowest hanging fruit. It's like installing a fancy air filter in your car but neglecting to even change the oil.
unfortunately if you're asthmatic there is a decent chance you are allergic to aspirin

So, Veganism is "established wisdom". More like unproven dogma...
A paleo diet is far more supportive of overall health. What that looks like for the individual is really down to them discovering what their body prefers, in terms of nutrients, carbs, fats and protein.
A paleo diet can be mostly veges, mostly meat, and anywhere in between.
"Paleo diet," as a concept, is uh... not based in reality. I honestly don't mean to be mean when I say that, there just isn't any other way to put it.
First, to recreate a "Paleolithic diet" we'd have to know exactly what Paleolithic humans ate, in which proportions, and we really don't. The evidence we have is incomplete. It's extremely doubtful humans in different groups in different geographic locations all ate the same thing - it's more likely humans adapted to their environment as that is exactly what humans tend to do.
It's not possible to eat a Paleo diet today, as the plants and animals that existed in paleolithic times no longer exist today. Natural and artificial selection has changed our food supply so drastically that the foods available today are almost completely unrecognizable compared to their Paleolithic ancestors.
(Ignoring for a second that humans have evolved since Paleolithic times as well. Also ignoring for a second the diseases of aging might not have appeared much in Paleolithic humans, to our knowledge, because there wasn't a whole lot of aging going on during that time...)
If you feel better following a fad diet, that's perfectly fine, just don't pretend it's any less "unproven dogma" than any other diet. The "Paleo diet" is based on a bad understanding of science, history, and anthropology.
A modern day Paleo diet is merely about eating as closely to natural foods as possible, eating those foods optimal for our individual health, and cutting out all processed junk foods.
Simple. It is certainly based in reality, much more so than the dogma of Veganism.
I swear some people just downvote without even trying to understand what I'm trying to convey... then again, maybe I could have explained a little better.
The modern "paleo" diet loaded with animal fat and protein is a modern invention that serves mostly to help people rationalize their taste preferences.
Paleo man definitely had access to multiple giant portions of meat a day -- just not every day.
After you kill the auroch, all that meat has to go somewhere.
Paleo man also ate the whole thing, not just the muscle meat. Some days, you might just have a giant bowlful of fat. Other days, you're eating paste made from acorns that have been leaching out their bitter compounds under a waterfall for a week.
Depending on where you lived, your tribe might have had access to many portions of meat every day for weeks, and then nothing but low-nutrition or semi-poisonous plants for months. It was a great incentive to develop either food preservation technology, agriculture, or a nomadic lifestyle. Which is to say: follow the meat, keep the meat from rotting until the herd passes through again, or eat more nutritious plants.
So there wasn't any one archetypal paleo diet. Paleo man had to adapt to his environment or die. The "paleo" idea is to reject foods that did not exist 10000 years ago, because supposedly human physiology hasn't evolved to deal with them yet. You invent a caricature of a cave man in your head and let him tell you what's food and what isn't.
~I don't recommend it. When I tried it, my cave man slipped on a wet rock while hunting, got a bad compound fracture, and died from an infection a week later, because antibiotics hadn't been discovered yet. My cave woman was out collecting sour berries and army worms, fell into a creek, and drowned. Then my cave baby was raised by wolves. I couldn't find the wolf milk and regurgitated caribou section in the supermarket, so I had to abandon the diet.~
It's difficult to know what the diet in the Paleolithic was but there is, I think, a component of the diet that we can be pretty sure about: occasional hungry. How we use that knowledge it's a different issue.
Not true ~ there is no "true" paleo diet ~ it varies vastly from culture to culture. Look at the Eskimos ~ their traditional diet was mostly animal, high in nutrients, protein, fat, and sugar in the form of glycogen, and very little in the way of plants. Then in other tribal cultures, they may subsist mostly on plant foods.
There's no One, True Diet. Veganism is actually rather unhealthy, because it excludes foods which contain highly bioavailable forms of nutrients not found in plant foods ~ Omega 3s, iron, etc.
An animal-based diet isn't unhealthy ~ it can be the most nutritious of all. Organ meats are extremely nutritious.
An animal-based diet isn't the problem ~ modern human societies run by greedy corporations and governments are, because they have created and supported the problems of animal abuse, because it is profitable.
> The modern "paleo" diet loaded with animal fat and protein is a modern invention that serves mostly to help people rationalize their taste preferences.
Bullshit. Paleo isn't all about fat and protein. That's keto. Paleo can be full of healthy carbs.
And the "paleo" diet most people eat is really just a rebranding of what people used to call the Atkins diet.
I feel the root cause of much of these issues is the practice of corporate farms to wall things off into atomic monocultures, and to separate animal husbandry from farming. I believe this is easier, for many reasons, but not more productive. It may be more economical, based on externalized pollution costs, and subsidized energy costs. I.E it has more to do with our arrangement of politics, rather than underlying fundamentals.
All one has to do is lookup bioavailable sources of iron.
I'll bet if you look at foods in a supermarket the main changes in ingredients will be more processed sugars and oils. This seems to happen in the UK when companies are taken over by USAmerican companies.
Processed meat is since a few years on the carcinogens lists (next to asbestos and smoking). But strange enough still on the hospital menus (also consumed by cancer patients)!
It takes a while I guess... Sadly.
The quality of the evidence that processed red meat causes cancer is now as good as the evidence that smoking causes cancer.
The strength of the effect is very very different. Smoking causes a lot of cancer. Red meat causes very little cancer.
It's completely incorrect to suggest red meat is equivalent to smoking for cancer.
Did I? Please read again. Just saying it's on the same list.

> Red meat causes very little cancer.
Could you please quantify how little cancer? Prolly not. This is difficult stuff. We do not know dosages, etc.
BTW, I was talking about "processed meat" (like hotdogs, bacon and nuggets), you now talk about red meat. Red meat is not on the cancer list (yet).
If you down voted me, please reconsider. Because I'm right.
You should be able to experiment with this by taking a CAC test every year or two.
The above is overly cynical and not completely true, but it is a good guide to the types of science that can be done in nutrition.
Which fats are pro- or anti-inflammatory also seems to be an area of active research: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4424767/
Nutrition is pretty terrible. It seems to me that laymen have zero chance of getting useful advice out of the research, other than "Eat a varied diet, move regularly".
