Syndrome X: medical nutrition therapy

A significant number of Americans are at risk for developing a condition of insulin resistance termed Syndrome X. Dyslipidemia, resistance to insulin, obesity, and blood pressure elevation--the deadly quartet--describe Syndrome X, which increases atherogenic risk and contributes to coronary artery disease. Lifestyle factors such as overeating and physical inactivity play a pivotal role in Syndrome X. This deadly duet has been aptly coined "hyperactive fork" and "hypoactive foot," respectively. In addition, emerging evidence suggests that certain nutrients may help protect against Syndrome X. This review provides a brief discussion of diet and lifestyle factors related to Syndrome X.
