Children with autism have lower levels of HDL
|
Scientists looked at blood levels of lipids and fatty acids in two groups of South Korean children – one group of typically developing boys and another group of boys with an autism diagnosis. Even though there were no major differences in what these children ate, those with autism had a lower omega-3 to omega-6 fatty acid ratio and lower levels of high density lipoprotein, more commonly known as HDL. For both levels, it’s often believed, the higher the better.

Diet rich in slowly digested carbs reduces markers of inflammation in overweight and obese adults

Among overweight and obese adults, a diet rich in slowly digested carbohydrates, such as whole grains, legumes and other high-fiber foods, significantly reduces markers of inflammation associated with chronic disease, according to a new study. Such a "low-glycemic-load" diet, which does not cause blood-glucose levels to spike, also increases a hormone that helps regulate the metabolism of fat and sugar.

A certain omega-3 fatty acid is necessary to construct the arch that turns a round, immature sperm cell into a pointy-headed super swimmer with an extra long tail, according to new research. The study shows that docosahexaenoic acid is essential in fusing the building blocks of the acrosome together. The acrosome is critical in fertilization because it houses, organizes, and concentrates a variety of enzymes that sperm use to penetrate an egg.

A new study showed no evidence to support this "perinatal programming" theory.
