Eating lots of saturated fat doesn't always lead to heart disease—it depends on what you eat instead. If you swap it with healthy foods, you might be fine, but if you swap it with junk food, it could be worse.
Eating foods with saturated fat, like butter or meat, doesn't seem to raise your risk of heart disease or dying from it, based on the studies reviewed.
Historical human populations consuming diets high in saturated fat from animal sources likely had higher circulating LDL cholesterol levels than contemporary populations, yet exhibited negligible rates of atherosclerotic cardiovascular disease.
