1. Green beansFilling up on green beans, and other high-fiber foods, can help you prevent weight gain or even promote weight loss—without dieting—suggests new research in The Journal of Nutrition. Researchers found that women who increased their fiber intake generally lost weight while women who decreased the fiber in their diets gained.
2. SalmonThe omega-3 fatty acids in oily fish—such as salmon and tuna—can boost your skin’s defenses against UV damage. In a study published earlier this year in the American Journal of Clinical Nutrition, researchers found that those who ate a little more than 5 ounces of omega-3-rich fish each week decreased the development of precancerous skin lesions by almost 30 percent. Scientists think the omega-3s act as a shield, protecting cell walls from free-radical damage.
3. BlueberriesEating just under a cup of mixed berries (such as red raspberries, strawberries, blueberries) daily for 8 weeks was associated with increased levels of “good” HDL cholesterol and lowered blood pressure—two positives when it comes to heart health—according to a recent study in the American Journal of Clinical Nutrition.
4. WatermelonResearch shows that eating foods that are full of water, such as watermelon, helps keep you satisfied on fewer calories. (Interestingly enough, drinking water alongside foods doesn’t have the safe effect.) At 92 percent water, watermelon is a good source of vitamin C. When it’s the red variety (some are orange or yellow), it also has lycopene, an antioxidant that may help protect against heart disease and some types of cancer.
5. TomatoesEating more vitamin-C rich foods, such as oranges, tomatoes, strawberries and broccoli, may be a secret to smoother skin. A igher intake of vitamin C from foods is associated with a lower risk of having wrinkled skin and age-related skin dryness in middle-age women. Vitamin C’s youthful effects on skin may be due to its antioxidant properties, which help protect against ultraviolet rays, and its role in keeping skin firm via collagen synthesis, say the researchers.
