Your Genes and Fat: Why Some People’s Cholesterol Rises More Than Others
Reducing saturated fat intake is known to lower “bad” cholesterol (LDL-C) and reduce heart disease risk, but responses vary widely between individuals. Research shows that genetics strongly influence how much LDL rises when people eat foods like butter, cheese, or fatty meats compared with unsaturated fats such as olive oil, nuts, and oily fish. Even on the same diet, LDL responses can differ by up to 1 mmol/L, reflecting genetic differences in intestinal cholesterol absorption and how efficiently LDL is cleared from the bloodstream.
