Nearly half of deaths due to heart disease, stroke and type 2 diabetes in the U.S. in 2012 were associated with suboptimal intake of certain foods and nutrients, according to a study published yesterday in the Journal of the American Medical Association. The largest numbers were related to high sodium, low nuts and seeds, high processed meats, low seafood omega-3 fats, low vegetables, low fruits and high sugar-sweetened beverages. “These results should help identify priorities, guide public health planning, and inform strategies to alter dietary habits and improve health,” the authors said.
