The Study
Animal-based and plant-based protein-rich foods and cardiovascular health: a complex conundrum.
This article is like a teacher giving their thoughts on a science topic using other people’s experiments. It doesn’t do any new experiments itself, so it can’t prove anything—it can only talk about what others found.
Analysis score
Maximum 0 for a editorial/opinion.
Where the score came from
Not all meat is the same — lean, unprocessed meat doesn’t raise heart risk as much as processed meat like sausages. What matters most is what else you eat, especially how much saturated fat is in your diet.
