Those studies were all ideological driven and would never pass replication.
Mongols vs China, diet was a defining factor in the Mongols victories.
Meat and dairy, the dairy gave them tons go vitamin D as well.
Source?
Iirc it was that the figting forces of the various northern chinese states were comprised of conscript peasants whose diet consisted of grain and not much else, which stunted their growth among other things, meaning the mongols were significantly larger and stronger than them leading to certain mythologizing in the centuries afterwards. It probably also didn't help that the conscripted peasants were, well, conscript foot soldiers, wheras the mongols were willing participants on horseback
Bang on, same thing with the Dutch and the Brits when the empire flourished.
Dietary changes drive a lot of these things, more than I think is generally understood and credited.
The Mongols are a very famous example and extreme as you stated the Chinese peasant and soliders mostly had a grain based diet and poor health that came with it.
From just 2 minutes with your paper: "Higher heme iron intake appeared to be significantly associated with a 31 % (95 % CI 4–67 %) elevated risk of developing CHD" --- lmao, loving that 95% confidence interval between 4 and 67%.
Passing those out as proof of real science keeps the disinformation and terrible practice alive. If I had a dime every time a random commenter gave me a link to an epidemiologic nutritional study, I could fund a double blind randomized one myself.
1: https://www.theguardian.com/science/2022/nov/29/plant-based-... — have fun reading the actual numbers in Tables 2, 3 and 4 of the linked paper.
if normally distributed, two thirds would have elevated risk between 14% and 48%
that is to say, almost everyone has an elevated risk - so I have no idea why you are complaining about confidence intervals
Yet white fish is one of the most recommended heart healthy foods.
You have to be careful when talking about specific mechanisms in terms of Whole Foods. Nutrition can't be reduced down to single mechanisms to provide confident recommendations, and often times results are the opposite of what we would expect mechanistically.
also, it's still lower than red meat, it's on the order of white meat
if you want an iron-rich fish you'd have to go up to bluefin tuna, which does have a red tint to its meat
But some people do not support their habits to be changed and are ready to believe anything that confort their opinions. Even if their habits destroy the planet.
I think you mean we have studies of dubious quality blaming red meat. And scores of people repeating the same trite arguments.
It's the same people that brought to you salt causes high blood pressure and saturated fat causes atherosclerosis, pushing the low fat craze and the obesity epidemic.
Sure, meat is bad, go eat hyper processed fake meat.
