Dementia is more common in people who live within 50 metres of a major road than those who live further away, according to a study looking at 6.6 million people published in The Lancet. However, the study found no link between traffic exposure and Parkinson's disease or multiple sclerosis.
The observational study estimated that up to one in 10 (7-11%) cases of dementia could be attributed to living near a major road  and that the link is strongest for those living closest to heavy traffic.
Research results present a new strategy for measuring the impact of zinc on health
A new study by researchers from the UCSF Benioff Children’s Hospital Research Institute (CHORI) shows that a modest 4 milligrams of extra zinc a day in the diet can have a profound, positive impact on cellular health that helps fight infections and diseases. This amount of zinc is equivalent to what biofortified crops like zinc rice and zinc wheat can add to the diet of vulnerable, nutrient deficient populations.
