10 Foods for a Longer Life

Grapefruit

Just call it the better-body fruit. In a study of 100 obese people at The Scripps Clinic in California, those who ate half a grapefruit with each meal lost an average of 3.6 pounds over the course of 12 weeks Some lost as much as 10 pounds. The study’s control group, in contrast, lost a paltry 1/2 pound. But here’s something even better: Those who ate the grapefruit also exhibited a decrease in insulin levels, indicating that their bodies had improved upon the ability to metabolize sugar. If you can't stomach a grapefruit-a-day regime, try to find as many ways possible to sneak grapefruit into your diet. Even a moderate increase in grapefruit intake should yield results, not to mention earn you a massive dose of lycopene—the cancer-preventing antioxidant found most commonly in tomatoes.
