BONE BUILDERS

1. 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.

2. Dried Plums 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.

3. Bok Choy This crunchy cruciferous vegetable is more than the filler that goes with shrimp in brown sauce. "Bok choy is rich in bone-building calcium, as well as vitamins A and C, folic acid, iron, beta-carotene, and potassium," says celebrity trainer Teddy Bass. Potassium keeps your muscles and nerves in check while lowering your blood pressure, and research suggests that beta-carotene can reduce the risk of both lung and bladder cancers, as well as macular degeneration. Shoot for a cup a day.

4. Oysters 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."

5. Bananas 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."

6. Kiwis Like bananas, this fuzzy fruit is high in bone-protecting potassium. "They're also rich in vitamin C and lutein, a carotenoid that can help reduce the risk of heart disease," says Bowerman. "I try to eat at least one or two a week after exercising." Freeze them for a refreshing energy kick, but don't peel the skin: It's edible and packed with nutrients.
