It's not a troll. I genuinely don't care what other people eat. I'm going to talk about it, and I want a place to talk about it.
The study you link to, is comically, linking all of the metabolic syndromes to the consumption of meat.
Let's consider diabetes, type 2 diabetes is defined as the inability for the body to regulate blood glucose. Blood glucose is introduced from the consumption of sugar, or carbohydrates, or fructose.
A type 2 diabetic can bring their blood sugar down, just by not eating glucose, or sugar, or fructose, or carbohydrates.
Fat, and protein, which is what most animal food is, does not introduce glucose into the blood.
Carbohydrates are converted to glucose in the liver. Someone who needs to maintain very strict glycemic control needs to be careful with grains and fruit.
