Newswise — Tired of spinach, bored with broccoli? Experts say there's a new generation of superfoods that promise to do double or triple-duty when it comes to preventing illness.

At the top of the list—kiwi. "In a recent study, kiwi was found to be one of the most nutritionally dense fruits out of 27 fruits," says Stephanie Dean, R.D., dietitian with Baylor University Medical Center at Dallas.

Kiwis are full of antioxidants, vitamin E and lutein. They ward off vision problems, blood clots, and even lower cholesterol—almost as effectively as the second new superfood on the list—barley.

"The USDA found that barley specifically could lower your LDL or 'bad' cholesterol by 17.4 percent which is a phenomenal percentage," adds Dean.

Barley, a grain, can be added to soups or even eaten instead of oatmeal for breakfast.

Next on the list is a traditional Thanksgiving favorite—cranberries.

"The crimson color of cranberries signal that they are full of flavonoids," explains Dean.

Flavonoids—high in antioxidants—help prevent everything from infections to strokes and cancer.

A drink milks the next spot on the list—kefir.

"Kefir is a wonderful source of calcium. Every eight ounce glass has about 300 milligrams which is a little less than one-third of the recommended daily intake for adults," says Dean.

Kefir not only contains just as much calcium as milk, but also packs more beneficial bacteria than yogurt.

And finally—a close cousin to an old superfood—broccoli sprouts.

"Broccoli sprouts have been shown to actually contain 20 percent more anti-cancer agents than regular broccoli," says Dean.

Broccoli sprouts are sold by the package and can be thrown on top of salads or can be a great addition to sandwiches.

Are these considered specialty foods or can you find them in most grocery stores? You can find them in most grocery stores; however, some are usually seasonal.
