Refined oils, fat, and animal protien cause arterial hardening immediately, lasting for several hours. Keep ingesting and you end up with heart disease....arteries filled with plaque restricting blood flow, raspiration, mental function. Ingesting refined sugar and flour causes an insulin spike (make fat out of carbs!) that lasts for hours causing a crash and repeated cravings for...more carbs. This leads to diabetes. Cancer needs sugar and animal protien to live.

Check out China study.

Fat is slept on macronutrient because of the misguided idea that increased fat = increased cholesterol in arteries. Vitamin K2 is an important vitamin that isn't metabolized well from foods containing K1 (vegetables). Animal sources and natto (fermented soy beans) are the best sources of it. It has been shown to help with heart disease, cancer and bone health.

The interesting thing with animal protein is that no study has shown a dose dependent increase in cancer when consuming more of it. Chronic inflammation from gluten, processed foods, pesticides, refined carbs, and refined sugars are the biggest culprits in dietary endorsed cancer.

So you are denying that endothelial dysfunction and it's triggers exist? Interesting.

Its triggers are high insulin, high fasting blood sugar, high triglycerides and low ldl. These are all caused by the food types I listed. High fat low carb diets have been shown to reduce all of these symptoms.

Citation for proof that arterial hardening happens immediately, and that animal protein specifically causes this (vs plant protein)? I've not seen this specific claim before.

I've seen the claim about animal protein many times before, never the sources.

It seems to be part of some pseudo-vegan zeitgeist. The denaturation process in cooking and digestion makes animal protein practically indistinguishable from plant protein. If there is any measurable dietary effect, it would be in the nutritional factors closely associated with those protein sources--for instance, the heme iron in animal meats, and the porphyric magnesium in green vegetable chlorophyll.

The proteins themselves are unlikely to have an effect beyond the ratios of their specific amino acid components, and the potential for indigestible misfolded prions. Animals are loaded with pepsins in their guts and proteases in the rest. By the time an amino acid reaches your arteries, if has already been broken down and built back up into something else.

A simple web search turns up pseudoscience and broscience everywhere. If there ever was a real dietary health study, it's now buried in the noise.
