Individuals with a genetic predisposition for elevated low-density lipoprotein (the “bad” cholesterol) levels have traditionally been instructed to reduce their consumption of saturated fats to lower their risk for heart disease. However, a team of heart disease and diet experts reviewed dietary guidelines for those with familial hypercholesterolemia and failed to find any evidence supporting a low saturated fat diet. They concluded that following a low-carbohydrate diet is a more effective dietary strategy for this group of patients. BMJ Evidence-Based Medicine, July 2020
