Omega-3 Fatty Acids and Vitamin D May Control Brain Serotonin, Affecting Behavior and Psychiatric Disorders

View | Comment

Although essential marine omega-3 fatty acids and vitamin D have been shown to improve cognitive function and behavior in the context of certain brain disorders, the underlying mechanism has been unclear. In a new paper published in FASEB Journal* by Rhonda Patrick, PhD and Bruce Ames, PhD of Children’s Hospital Oakland Research Institute (CHORI), serotonin is explained as the possible missing link tying together why vitamin D and marine omega-3 fatty acids might ameliorate the symptoms associated with a broad array of brain disorders.

Keeping the Heart's Engine in Sync: Study Shows Contractions Rely on Critical Protein for Efficient Function

Vermont researchers have identified a remarkable protein that helps choreograph the highly specific series of events that ensure the heart beats consistently and accurately. Called myosin-binding protein C (cMyBP-C), this protein performs its masterpiece inside the sarcomere, a part of the heart muscle tissue that is one-fiftieth the diameter of a human hair. Trillions or more sarcomeres must contract simultaneously in order for the heart to maintain its beat. Problems with this protein can cause sudden death via a condition called hypertrophic cardiomyopathy.

Popular Soda Ingredient Poses Cancer Risk to Consumers

View | Comment

Public health researchers have analyzed soda consumption data in order to characterize people’s exposure to a potentially carcinogenic byproduct of some types of caramel color. Caramel color is a common ingredient in colas and other dark soft drinks. The results show that between 44 and 58 percent of people over the age of six typically have at least one can of soda per day, possibly more, potentially exposing them to 4-methylimidazole (4-MEI), a possible human carcinogen formed during the manufacture of some kinds of caramel color.
