Now, for the first time, a new analysis of nationwide dietary data has found an association between consumption of added sugar and higher risk of death from cardiovascular disease.

Contrary to long-standing concerns about the stimulant effect of caffeine sparking atrial fibrillation, a new analysis concludes that its unlikely habitual caffeine intake from coffee and other dietary sources increases risk.

Its not just the recession thats led to improvements in the US diet, according to a new analysis in the American Journal of Clinical Nutrition. Beyond merely cutting back for pocketbook reasons, Americans are choosing to consume fewer calories and obesity rates are leveling off.

Already a concern for older adults who lack adequate stomach acid to extract natural vitamin B12 from food, B12 deficiency may be more widespread than previously thought. The largest study to date of the effects of popular heartburn and ulcer medications on the risk of vitamin B12 deficiency reports a potentially serious problem.

Eating a daily handful of nuts-about one ounce or three tablespoons-could reduce your risk of dying from the most common causes of death. Results from the largest study of its kind, following nearly 119,000 men and women for up to 24 years, show that regular consumers of any type of nuts were less likely to die from heart disease, cancer and lung disease or from all causes than non-nut eaters. As frequency of nut consumption went up, mortality risk dropped.

The US Food and Drug Administration (FDA) finds itself in the middle of the tussle over whether foods labeled as natural can contain genetically modified (GMO) ingredients. The Grocery Manufacturers Association is petitioning the agency to specifically authorize natural labeling on GMO products, such as those containing bioengineered corn, soy, canola or sugar. The trade association cited the proliferation of lawsuits challenging natural labeling, with 65 pending class-action cases across the country. At the same time, three federal judges presiding over such cases have asked the FDA to rule on whether GMO ingredients belong in natural foods.
