The Effects of a Multivitamin/Mineral Supplement on Micronutrient Status, Antioxidant Capacity and Cytokine Production in Healthy Older Adults Consuming a Fortified Diet

Background: Inadequate micronutrient intake among older adults is common despite the increased prevalence of fortified/enriched foods in the American diet. Although many older adults take multivitamin supplements in an effort to compensate, studies examining the benefits of this behavior are absent.
Objective: To determine whether a daily multivitamin/mineral supplement can improve micronutrient status, plasma antioxidant capacity and cytokine production in healthy, free-living older adults already consuming a fortified diet. Continue reading
Homocysteine Elevation in Sickle Cell Disease

Objective: Ischemic complications are common in patients with sickle cell disease. Hyperhomocysteinemia is a risk factor for arteriosclerosis and venous thrombosis, and given the propensity of patients with sickle cell disease to develop ischemic complications, we hypothesized that they might have elevated plasma homocysteine concentrations.

Comparative Cholesterol Lowering Properties of Vegetable Oils: Beyond Fatty Acids

Objective: Our laboratory has previously reported that the hypolipidemic effect of rice bran oil (RBO) is not entirely explained by its fatty acid composition. Although RBO has up to three times more serum cholesterol-raising saturated fatty acids (SATS) than some unsaturated vegetable oils, we hypothesized that its greater content of the unsaponifiables would compensate for its high SATS and yield comparable cholesterol-lowering properties to other vegetable oils with less SATS.
