We measured the in vitro effects of mercuric chloride (Hg2+) and selenite (Se4+) on hepatic 2-thiobarbituric acid-reactive substances (TBARS) and non-protein sulfhydryl (NPSH) levels of rats fed diets enriched with polyunsaturated or saturated fatty acids with and without cholesterol. ⋯ Together these results indicated that the protective effect of Se4+ against mercury-induced lipid peroxidation depends on dietary fat saturation.

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.

Randomized Controlled Trial Clinical Trial
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.
