I would only add to be careful when talking to doctors. There are still doctors that talk in terms of good and bad cholesterol rather than taking a lipid panel and getting a graph of small dense to large buoyant particles within the cholesterol. To make matters worse many of them in the USA have been corrupted by financial incentives to push statins and that is another deep and endless topic all in and of itself.

another point worth mentioning is some substances the body cannot synthesize: vitamins, amino acids.

cholesterol.. cholesterol is not one of them. the body happily synthesizes as much cholesterol as it likes. so diet this and diet that associate with high cholesterol, sure. but also genetic. if the body synthesizes cholesterol, there will be population variation in how much cholesterol or how little cholesterol a person makes. And yes, some people do have super duper high cholesterol and go on statins automatically. so if someone says me "this person had high cholesterol, this one low, what's with that, we have not disproven a genetic contribution in the first place not to mention a gorillion other confounders

He's right to point out the difference. Human metabolic pathways for processing carbs and fats are capable of functioning independently and lab animals used as human analogs can live happy healthy lives exercising either. But they seem to interfere with each other when both are operating simultaneously, even in the lab animals, and that results in obesity and decreased quality of life outcomes.

Not referring to simply the hosted site, only to the existence of NYP. They are an awful sensationalized, rage bait website that has a long history of making stories up. You really shouldn’t be paying any attention or traffic to them.
