New study defies conventional wisdom, but experts not convinced

(NEWSER) - In a world with constantly changing nutritional guidelines (eggs are bad for you; no, they're good for you! ), one food has seemed to be consistently maligned: salt. But a new, and highly contested, study finds that low-salt diets do not prevent high blood pressure—and actually increase the risk of death from heart attack or stroke.

Supporters, however, claim that other studies have found adverse effects from low-sodium diets. More»

People who live near vegetation suffer fewer diseases

(NEWSER) - People who live close to parks or other “green spaces” are likely to be healthier, a new study suggests. Dutch researchers scoured the health records of 345,000 people, comparing their health status to the amount of green space in the surrounding area, from a half-mile to 2-mile radius. Of 24 health conditions—including cardiovascular, respiratory, and neurological diseases—people living in purely urban areas suffered higher instances of 15 of them, notes HealthDay. More»

(NEWSER) - Americans eat more than twice as much added sugar as doctors recommend, and they should cut back to battle obesity, hypertension, diabetes, and heart disease, researchers say. Added calories from processed sugar should total no more than 150 for men and 100 for women, the American Heart Association said today. Soft drinks are the top factor in added dietary sugar, and the recommendations are sure to rile their producers, Reuters reports. More»
