Trans Fats Linked with Memory.
Consuming trans fats is associated with worsened memory in young and middle-aged males, according to a study of 1,000 healthy men. Researchers analyzed trans fat intake through questionnaires and assessed memory using 104 cards with words written on them. Participants consuming the most trans fats remembered 10 percent fewer words compared to those consuming the least amount.

Magnesium May Lower Risk of Metabolic Syndrome.
A meta-analysis examined six studies, which included 24,473 people and 6,311 cases of metabolic syndrome, a cluster of risk factors that raises the risks for heart disease and type 2 diabetes. The average magnesium intake was 117-423 milligrams (mg) per day. People with the highest magnesium intakes had a 31 percent lower risk of metabolic syndrome, compared to people with the lowest intakes. Every 100 mg per day increase in magnesium reduced the risk by 17 percent. The RDA for magnesium, found in green leafy vegetables, nuts, and whole grains, is 210-420 mg per day, depending on age and gender.

Soda Consumption May Cut Years Off Life.
Researchers from the University of California, San Francisco, conducted a study using data from the National Health and Nutrition Examination Surveys, including 5,309 adults 20-65 years of age. Using 24-hr diet recalls and DNA samples that measured telomere length (shortened telomeres indicate aging), they found that sugar-sweetened soda intake was associated with shorter telomeres. Drinking 20 ounces of soda daily was associated with 4.6 years of additional biological aging.
