Hypercholesterolemia is a major risk factor for the development of coronary artery disease. Studies have shown that several vitamins and nutritional supplements may contribute to a reduction in total and low-density lipoprotein cholesterol. This goal of this study was to document the use of vitamins and nutritional supplements that may treat or prevent hypercholesterolemia. ⋯ The use of vitamins and nutritional supplements that may reduce total and low-density lipoprotein cholesterol levels is low in the United States. Future research is needed to confirm the effectiveness of these products, examine the quality and purity of currently available products, and explore whether using these supplements are an adequate low-cost alternative to pharmaceuticals now available.

A great deal of epidemiologic evidence has indicated that fruits and vegetables are protective against numerous forms of cancer. However, there are many gaps in our knowledge. ⋯ The inverse association between intake of fruits and vegetables and the risk of cancer of the colon, breast, and stomach has generally been much stronger in case-control than in cohort studies. We have no clear explanation for this.

Weight loss and total lipid profile changes in overweight women consuming beef or chicken as the primary protein source.
Conflicting recommendations are prevalent regarding the appropriateness of red meat versus white meat consumption for individuals aiming to reduce body weight and cardiovascular disease risk. ⋯ These findings demonstrated that weight loss and improved lipid profile can be accomplished through diet and exercise, whether the dietary protein source is lean beef or chicken.

To highlight the clinical and metabolic correlates of abdominal obesity and various abdominal adipose tissue depots. ⋯ Several physiological and metabolic parameters are site-specific in abdominal adipose tissue. The epidemiological, clinical, and prognostic significance and relative importance of the regional adipose tissue depots, however, remain to be ascertained.
