Salt and Your Weight
Most Americans eat too much salt every day, mostly in processed foods and restaurant meals. Now, two linked studies suggest that an abundance of salt may lead to weight gain. In the first study, 10 Russian cosmonauts in training followed three diets—each for at least several weeks—that varied only in their salt content. After several months, researchers discovered that the saltiest diet made the cosmonauts hungry; surprisingly, they also drank less water than with the less-salty food. Based on a follow-up study of mice, the researchers theorize that the cosmonauts’ bodies burned many calories in order to produce that missing water, which may explain their hunger. And that hunger could lead to overeating. It’s another reason to curb how much salt you swallow.
