A proposal issued today by the U.S. Food and Drug Administration, if finalized, would effectively make trans fat in the food supply a thing of the past. The Gazette asked Professor Walter Willett, chair of the Department of Nutrition at the School of Public Health, to discuss the potential impact of the ruling, in policy…

Skip the juice, go for whole fruit

‘Whole grain’ not always healthy
U.S. Department of Agriculture’s 2010 Dietary Guidelines recommend that Americans consume at least three servings of whole-grain products daily, and the new U.S. national school lunch standards require that at least half of all grains be whole-grain rich. However, no single standard exists for defining any product as a “whole grain,” according to a Harvard…

Study shows benefits of eating fish greatly outweigh risks
Many studies have shown the nutritional benefits of eating fish (finfish or shellfish). Fish is high in protein and omega-3 fatty acids. But concerns have been raised in recent years about chemicals found in fish from environmental pollution, including mercury, PCBs and dioxins. That has led to confusion among the public – do the risks…

High intake of vitamin D linked to reduced risk of multiple sclerosis
More than 185,000 women from the Brigham and Women’s-based Nurses’ Health Study and Nurses’ Health Study II, who were free of multiple sclerosis (MS), were selected for a research study. The participants filled out dietary questionnaires every four years between 1980 and 1999 that assessed their vitamin D intake along with other dietary information. During…

Low-carb more effective than low-fat
A study put three groups of dieters on different regimens. They included a low-fat group, a low-carbohydrate group that ate the same number of calories, and a third group on a similar low-carbohydrate plan that included 300 extra calories a day. The low-carbohydrate dieters lost more weight than low-fat dieters despite eating 25,000 extra calories…

More than 44,000 men and nearly 99,000…

Medical student engineers protein to dissolve blood clots
Heart attacks and strokes are caused by blood clots called thrombi that block blood flow in the arteries of the heart and of the brain.
