Apolipoprotein B, or ApoB for short, is a protein involved in lipid metabolism and is a robust predictor of cardiovascular disease risk. Healthy lifestyle behaviors, such as following a Mediterranean diet, exercising, and taking supplements like zinc and omega-3 fatty acids, may reduce ApoB levels. Individual responses to diet can be influenced by a person's genetic makeup, however. Knowing a person's genetic factors influencing their response to diet may be beneficial component of a multi-part strategy developed in coordination with professional care for keeping ApoB in check.
