For more than 65 years, doctors have told their patients that they could lower blood cholesterol levels and prevent heart attacks by substituting polyunsaturated fats from plants for saturated fats from animals.
A 2016 review of research done more than 40 years ago showed that while this lowers blood cholesterol levels, it is associated with increased risk for heart attacks and premature death. Since the majority of the scientific literature has shown that polyunsaturated fats in vegetables are healthful and help to prevent heart attacks, we have to find an explanation for why adding large amounts of polyunsaturated fats extracted from plants could increase the rate of heart attacks.
You can get these most healthful oils by eating nuts, avocados, beans, sunflower seeds, and other plant matter that is high in fats.
