there are literally thousands of studies. there's no real scientific debate amongst people that know what they are talking about. Red meat, and any food high in saturated fats, are awful for your heart. full stop. that includes sausage, steak, ham, butter, etc.

the people eating "lean steaks" are fooling themselves. There's no such thing as "clean beef" it all has high amounts of bad fats. Are some worse than others? of course but let's not kid ourselves.

There is literally no proof for any of that. In fact, scientists recently seem to be walking back on the whole "saturated fat bad" stuff. Because nutritional science is less science, and more "monetary interests + blind faith".

There is very little science in nutrition, despite the existence of thousands of studies. There are huge gaps in even the basics of nutrition understanding, and we are constantly discovering new confounding variables. Some dietary fibers were being counted as carbs as late as the 2000s. The huge impacts of the gut microbiome on digestion of food has barely been recognized in the last 10 years, and we still basically know nothing about it. Inter-personal variations in base metabolic rates and/or absorption of nutrients from food is gigantic, with basically no known reasons for it (some of the difference is tied to muscle mass, but even if you eliminate differences in muscle mass, there are still large differences that remain), and no inclusion in common models and dietary recommendations.

I'm not trying to say that red meat is good for you. I'm just saying we have no real idea, and you really shouldn't trust a doctor about any of this stuff any more than you should trust the latest health influencer crackpot. Try things out, see if you can eat similarly to people you know who are in good health, and get blood work done regularly to see if you're ok. Probably avoid highly synthesized foods.

Says you? because that's not what cardiologists, nutritionists and doctors say. around the world. there's a ton of real, good science from many countries that show a very clear link between increased saturated fat intake, CVD and LDL-C levels. It's not really in question.

You are essentially hand waving away 80+ years of scientific studies and data because...you said so?

> you really shouldn't trust a doctor about any of this stuff any more than you should trust the latest health influencer crackpot.

This is an insane take and thoroughly discredits anything you have to say. Science has some basis in reality, even if it is somewhat flawed. The idea that we should throw out all science food guidelines because it's not perfect is completely crackpot.

I have no idea why nutrition brings out the crazy left field engineer types but it's a common pattern.
