Mixed Fiber Supplements and Cholesterol

Why was this study done? Water-soluble fiber can play an important role in the maintenance of blood lipids (cholesterol), but not all water-soluble fibers are useful for lipid-lowering. This series of small studies were designed to understand differing effects of water-soluble fibers, combination, and concentration of fibers on blood lipid levels. What did the study…

Uncovering the Ideal Formula for Rehydration

Why was this study done? Astronauts commonly experience dehydration during long flights. It is important to understand the role of rehydration formulas and their ability to prevent dehydration (maintenance of plasma volume). This study was designed to better understand the role of differing concentrations of rehydration formulas on dehydrated subjects. What did the study find?…

How to Best Rehydrate During Exercise

Why was this study done? Athletes who engage in long exercise bouts have an interest in sparing muscle glycogen (short-term storage of glucose) because of the dramatic reduction of energy output and fatigue that occurs when glycogen is depleted (known colloquially as “hitting the wall”). This study was designed to help understand how varying exercise…

Mixed Combination Fiber and Cholesterol Levels

Why was this study done? Water-soluble fibers are a well-recognized tool for lowering cholesterol levels. This study was designed to understand the effects of a combination of water-soluble fibers (psyllium, pectin, guar gum, and locust bean gum) when compared to acacia gum alone. What did the study find? The mixture of fibers (psyllium, pectin, guar…

Optimizing Post-Exercise Recovery

Why was this study done? The role of hormones (insulin, testosterone, growth hormone) in muscle building is fairly well established. What is less understood is the role of macronutrients (protein, carbohydrate, fats) and their impact on those hormones. This study was designed to help understand the importance of post-exercise supplementation for anabolic hormone production. Participants…

Alfalfa and Canavanine

Why was this article written? There had been a concern raised about L-canavanine (an amino acid present in alfalfa seeds and sprouts) and vitamin E and their relationship to autoimmune disorders. The basis for these concerns appeared in a case study published in a journal. Alfalfa supplements, which are manufactured using mature alfalfa (and not…
