Way Better Whey

1 Whey May Beat Soy for Weight Loss

Whey, or milk, protein might be a better choice than soy for weight loss help, find researchers from the U.S. Department of Agriculture's Human Nutrition Research Center. The study, published in Journal of Nutrition, shows that people who drank whey protein shakes lost body fat and inches around the waist, while those drinking soy shakes stayed at the same weight. People in the study who consumed carbohydrate shakes gained weight. Study participants weren't aware of which type of protein shake they were drinking, but researchers found that those who had the whey shakes had much lower blood levels of ghrelin, a hormone that helps regulate food intake. WebMD reports that the research was partially funded by the dairy industry.

Adding Life to a Lifesaver

2 Stored Blood’s Loss of Function Understood

Researchers at Duke University Medical Center have found that red blood cells (rbcs) lose nitric oxide and lower their release of adenosine-5'-triphosphate (ATP), decreasing its mobility through blood vessels and giving it a sticky quality, respectively. Nitric oxide makes blood vessels dilate and ATP prevents the blood from adhering to the lungs’ blood vessels. Both molecules are necessary to move rbcs through the body to carry oxygen to tissues. Sticky rbcs can result in problems such as heart attacks and respiratory failure. This is one of a few studies looking at how rbcs lose their ability to efficiently transport oxygen and this new understanding could lead to new storage techniques such as adding ATP or a compound that increases its release to donated blood.
