Vitamin D may prevent Type 1 diabetes
A new analysis of current research provides “the strongest evidence to date” that giving small children supplemental vitamin D will help prevent them from developing type 1 diabetes later on, according to the review’s co-author. Vitamin D is produced in the skin with sun exposure. Deficiency in the nutrient can lead to a host of health problems. Because breast milk typically contains little vitamin D, the American Academy of Pediatrics recommends vitamin D supplements for nursing infants and UK public health authorities say that all children should receive the supplements for at least the first two years of life. Overall, they found, infants who were supplemented with Vitamin D were 29 per cent less likely to develop type 1 diabetes than children who had not received supplements. 

Fish diet may protect against clogged arteries
A diet rich in oily fish, which contains omega-3 fatty acids, may be why middle-aged men in Japan have fewer problems with clogged arteries than White men and men of Japanese descent in the United States, a study has found. The research, published in the Journal of the American College of Cardiology, found that Japanese men living in Japan had twice the blood levels of omega-3 fatty acids and lower levels of atherosclerosis compared to middle-aged White men or Japanese-American men living in the United States.
