In recent times there’s been a lot of promotion of the “super powers” of food in the health and wellness industry. From bone building, brain building, beauty, longevity, to cures for certain diseases, there are foods found (some through scientific research, some based on ancient beliefs) to standout as foods that boost the human body in some special way. Here’s a list of 15 foods with Superpowers.
Alaskan King Crab
High in protein and low in fat, the sweet flesh of the king crab is spiked with zinc—a whopping 7 milligrams per 3.5-ounce serving. “Zinc is an antioxidant, but more important, it helps support healthy bone mass and immune function,” says Susan Bowerman, assistant director of the Center for Human Nutrition at the University of California at Los Angeles. “Several studies have linked adequate zinc intake to increased immunity and decreased incidences of respiratory infection.” And you can reap all these benefits by swapping one of your weekly fish meals for a six-ounce serving of crab.
Also known as prunes, these dark shrivelers are rich in copper and boron, both of which can help prevent osteoporosis. “They also contain a fiber called inulin, which, when broken down by intestinal bacteria, makes for a more acidic environment in the digestive tract,” says Bowerman. “That, in turn, facilitates calcium absorption.” Enjoy four or five a day to strengthen your bones and boost your energy.

Shellfish, in general, is an excellent source of zinc, calcium, copper, iodine, iron, potassium, and selenium. “But the creamy flesh of oysters stands apart for its ability to elevate testosterone levels and protect against prostate cancer,” says Bass. “They aren’t a food most people will eat regularly, but getting five into your diet twice a week will make your weekends more fun.”
Athletes and performers are familiar with the calming effect of bananas—a result of the fruit’s high concentration of tryptophan, a building block of serotonin. But their real benefit comes from potassium, an electrolyte that helps prevent the loss of calcium from the body. “Bananas also bolster the nervous system, boost immune function, and help the body metabolize protein,” says Bass. “One banana packs a day’s worth of potassium, and its carbohydrate content speeds recovery after strenuous exercise.”
Our president’s dad may hate this cruciferous all-star, but one cup of broccoli contains a hearty dose of calcium, as well as manganese, potassium, phosphorus, magnesium, and iron. And that’s in addition to its high concentration of vitamins—including A, C, and K—and the phytonutrient sulforaphane, which studies at Johns Hopkins University suggest has powerful anticancer properties. “One cup a day will do the trick,” says Bowerman. Try cauliflower, kale, brussels sprouts, or cabbage for variation, as all possess many of the same nutritional qualities. “Broccoli may also help reduce excess estrogen levels in the body, thanks to its indole 3-carbinol content,” says celebrity trainer Gunnar Petersen.
A renowned muscle builder, spinach is also rich in vitamin K, which has been shown to bolster bone-mineral density (thus protecting against osteoporosis) and reduce fracture rates. Spinach is also high in calcium, phosphorus, potassium, zinc, and even selenium, which may help protect the liver and ward off Alzheimer’s. One more reason to add it to your diet: A study in the Journal of Nutrition suggests that the carotenoid neoxanthin in spinach can kill prostate cancer cells, while the beta-carotene fights colon cancer. “Popeye was on to something,” says Bowerman. “Eat one cup of cooked spinach, or two cups raw, four times a week.”
Lauded for centuries as an aphrodisiac, this fiber-rich plant contains more bone-building magnesium and potassium than any other vegetable. Its leaves are also rich in flavonoids and polyphenols—antioxidants that can cut the risk of stroke—and vitamin C, which helps maintain the immune system. “Eat them as often as you can,” says Bowerman. Ripe ones feel heavy for their size and squeak when squeezed.
Studies show that green tea—infused with the antioxidant EGCG—reduces the risk of most types of cancer. “The phytonutrients in tea also support the growth of intestinal bacteria,” says Bowerman. “Specifically, they inhibit the growth of bad bacteria—E. coli, Clostridium, Salmonella—and leave the beneficial bacteria untouched.” Why is this important? “Because up to 70 percent of your immune system is located in your digestive tract,” says Bowerman. “Four cups a day will keep it functioning at its peak.”
“Chilis stimulate the metabolism, act as a natural blood thinner, and help release endorphins,” says Petersen. Plus, they’re a great way to add flavor to food without increasing fat or calorie content. Chilis are also rich in beta-carotene, which turns into vitamin A in the blood and fights infections, as well as capsaicin, which inhibits neuropeptides (chemicals that cause inflammation). A recent study in the journal Cancer Research found that hot peppers even have anti-prostate-cancer properties. All this from half a chili pepper (or one tablespoon of chili flakes) every day.
Contrary to popular belief, ginger—a piquant addition to so many Asian dishes—isn’t a root, it’s a stem, which means it contains living compounds that improve your health. Chief among them is gingerol, a cancer suppressor that studies have shown to be particularly effective against that of the colon. Chop ginger or grind it fresh and add it to soy-marinated fish or chicken as often as you can. The more you can handle, the better.
“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. One serving (3.5 ounces) contains more antioxidants than any other fruit. Drizzle with lemon juice and mix with strawberries for a disease-fighting supersnack.
Often confused with yams, this tuber is one of the healthiest foods on the planet. In addition to countering the effects of secondhand smoke and preventing diabetes, sweet potatoes contain glutathione, an antioxidant that can enhance nutrient metabolism and immune-system health, as well as protect against Alzheimer’s, Parkinson’s, liver disease, cystic fibrosis, HIV, cancer, heart attack, and stroke. “One sweet potato a day is a great alternative to the traditional variety,” says Clark.
“I think of tomatoes as the ‘fighting herpes helper’ for the divorcé crowd,” says Petersen. Their lycopene content can also help protect against degenerative diseases. “Cooked tomatoes and tomato paste work best,” he says. Shoot for half a tomato, or 12 to 20 ounces of tomato juice, a day.
Packed with potassium, manganese, and antioxidants, this fruit also helps support proper pH levels in the body, making it more difficult for pathogens to invade, says Petersen. Plus, the fiber in figs can lower insulin and blood-sugar levels, reducing the risk of diabetes and metabolic syndrome. Select figs with dark skins (they contain more nutrients) and eat them alone or add them to trail mix. Newman’s Own fig newtons are also a quick and easy way to boost the immune system. Aim for four figs per week.
Delicious when added to brown rice or quinoa, these mushrooms are rich in the antioxidant ergothioneine, which protects cells from abnormal growth and replication. “In short, they reduce the risk of cancer,” says Bowerman, who recommends half a cup once or twice a week. “Cooking them in red wine, which contains the antioxidant resveratrol, magnifies their immunity-boosting power.”
