Previously, a number of studies have reported that high levels of homocysteine relate to an increased risk of cognitive decline, and that B vitamins may serve as cofactors for enzymes involved in the metabolism of homocysteine. Aron M. Troen, from Tufts University (Massachusetts, USA), and colleagues analyzed data from 2000 study subjects who participated in The Boston Puerto Rican Health Study and the Nutrition, Aging, and Memory in Elders study. The researchers found that low levels of vitamin B-6 and B-12 are associated with an increased risk of impaired cognition. Further, the team found that low levels of B-12 were associated with an increased risk of depression.

15. Delaying Diabetes
New data models derived from the Diabetes Prevention Project by the University of Michigan Health System (USA) show that men and women who walked briskly for 30 minutes five days a week, lowered their fat and calorie intake, and achieved a weight-reduction goal of 7% of body weight over a three-year period were able to cut their risk of developing type 2 diabetes by 58%.
