Then why was heart disease relatively uncommon up until 90+ years ago? Even though meat / animal fat consumption was at It's highest? Why do every Indigenous native culture around the planet who've lived off the land for thousands of years have no Instances of heart disease? or any modern illnesses for that matter( Prior to the introduction to western foods like flour and sugar) These were people who lived as hunter gatherers. They subsisted off animal fats. Care to explain that? Since you're so certain that cholesterol and saturated fat contributes to heart disease. I'm sorry but the science has completely disproven many of these Ideas. They are outdated and there was never adequate proof for them to begin with.
