This study was designed to investigate the effects of a standard carbohydrate meal of approximately 58 grams, consumed along with varying amounts of protein 0, 15.8, 24.1, 33.6, and 49.9 grams to determine…

Which is the Best Type of Beta-Carotene?

Why was this study done? Differing shapes of identical chemicals (called isomers) can have differing effects on humans. The “cis” isomer of beta-carotene have shown in animal studies to have lower vitamin A activity, but humans have different physiology than animals. This study was designed to investigate how different isomers of beta-carotene act in humans.…

Water-Soluble Guar Gum and Cholesterol Lowering

Why was this study done? Cholesterol lowering can be accomplished through non-pharmacological means (diet, exercise, weight loss) and dietary fiber plays an important role in a cholesterol-lowering plan. This study was designed to investigate the effects of both solid and liquid guar gum on plasma lipid levels (cholesterol, HDL, LDL) in people with moderately high…

Effect of High Calcium Intake on Magnesium Excretion

Why was this study done? Supplementing with calcium is an effective tool for bone maintenance, but it has long been postulated that high calcium intake may negatively affect other minerals (especially magnesium). This study was designed to investigate the effects of a high calcium supplementation (1500 mg/day for 10 days) on magnesium excretion. What did…

Omega-3 Fish Oils and Blood Lipid Levels

Why was this study done? Population studies have long shown a lower incidence of heart disease in cultures who consume a large portion of their diet as cold-water fish. These observations have led to the hypothesis that omega-3 fatty acids (EPA, DHA) might be responsible for the cardiovascular effects of these diets. This study was…
