Now salt is good for you?

Many studies have shown that cutting sodium consumption lowers blood pressure. But it may not necessarily be good for overall health, according to an analysis released last week.

The research was conducted by Niels Graudal of Copenhagen University Hospital in Denmark for the Cochrane Collaboration, a highly respected international group that assesses scientific evidence about health issues. Graudal and his colleagues analyzed 167 studies conducted between 1950 and 2011 that compared people who consumed low-sodium vs. high-sodium diets.

Low-sodium diets did cut blood pressure levels in people with high and normal blood pressure, the researchers found. But it also significantly increased other risk factors for heart disease, such as cholesterol levels, triglycerides, adrenaline and renin, the researchers reported in the American Journal of Hypertension.

Soda in schools

Restricting the sale of soda and other sugar-sweetened beverages in schools doesn’t make a dent in students’ overall consumption of those high-calorie drinks, research published last week finds.

A study in the Archives of Pediatrics & Adolescent Medicine surveyed 6,900 students at 40 public schools across the nation.

Whether kids went to school in states where sales of sodas but not other sugar-sweetened beverages were prohibited, in states where all sugar-sweetened beverages were prohibited or in states where no policy was in place, 85 percent reported having consumed a sugar-sweetened beverage during the seven days preceding the survey.

And between a quarter and a third of students said they drank soda daily, no matter what their state’s policy.
