The 40 Best Age-Erasing Superfoods - Part 2

5. Spinach

It may be green and leafy, but spinach—a renowned muscle builder—is also the ultimate man food. The heart-health equivalent of a firstballot Hall of Famer, spinach is replete with the essential minerals potassium and magnesium, and it’s one of the top sources of lutein, an antioxidant that may help prevent clogged arteries. Plus its vitamins and nutrients can bolster bone-mineral density, attack prostate cancer cells, reduce the risk of skin tumors, fight colon cancer, and, last but not least, increase blood flow to the penis. “Popeye was on to something,” says Susan Bowerman, assistant director of the Center for Human Nutrition at the University of California at Los Angeles.

6. Rosemary

The carnosic acid found in this spice has been shown to reduce stroke risk in mice by 40 percent, according to a study published in the Journal of Neurochemistry. Carnosic acid appears to set off a process that shields brain cells from free-radical damage, which can worsen the effects of a stroke. It can also protect against degenerative diseases like Alzheimer’s and the general effects of aging.

7. Wild Salmon

A 4-ounce serving of salmon has approximately 2,000 milligrams of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), omega-3 fatty acids that serve as oil for the brain’s hardware by helping nerve cells communicate with one another. Thirty-five percent of your brain consists of fatty acids like these, but they can decline as the years stack up. A 2008 University of Cincinnati study, for instance, found that the brain tissue of 65- to 80-year-olds contained 22 percent less DHA than the brain tissue of 29- to 35-year-olds. “If you want to keep your wits about you as you age, start consuming omega-3s now,” says William Harris, Ph.D., a nutrition researcher at the University of South Dakota. Why is wild so important? Because farmed fish, which are fattened with soy, can be as high in inflammatory omega-6 fats as a cheeseburger. If in doubt, opt for sockeye salmon, which can’t be farmed and is always wild. Aim for at least two servings a week, says dietitian Joan Salge Blake, author of Nutrition and You.

8. Blueberries

“This potent little fruit can help prevent a range of diseases from cancer to heart disease,” says Ryan Andrews, the director of research at Precision Nutrition, in Toronto, Canada. Think of blueberries as anti-rust for your gray matter, too. Besides being rich in fiber and vitamins A and C, they’re also packed with antioxidants—only açai, an Amazonian berry, contains more—that neutralize the free radicals that cause neuronal misfires. Eat a cup a day, and opt for wild blueberries whenever possible, as they contain 26 percent more antioxidants than cultivated varieties.
