nuts

U.S. adults put on about a pound a year on average. But people who had a regular nut-snacking habit put on less weight and had a lower risk of becoming obese over time, a new study finds.

Men and women who were regularly munching on peanuts or tree nuts in their 30s and 40s were significantly more likely to reach their 70s, a study found. Researchers say they aren't sure why nuts promote longevity, but they think it has to do with how they affect metabolism and satiety.
