Tortilla chips are not the healthiest snack, but choosing ones made with blue corn may provide some advantages. Researchers in Mexico found that blue corn chips have 20 percent more protein and 9 percent less starch than those made with white corn.

Compared with yellow or white corn chips, blue corn chips are lower on the glycemic index, the measure of a food’s effect on the body’s blood-sugar level. Some studies indicate that a low-glycemic diet is linked with weight loss and improves insulin sensitivity.

Blue corn chips are also richer in anthocyanins, antioxidants that trap free radicals to prevent cell damage. Researcher Luis A. Bello-Perez says the lower glycemic index of blue corn chips may benefit dieters and diabetics. [source: Allure]

Britney Spears has lost 20 pounds. Actually, a source claims that Britney has lost anywhere from 10 to 20 pounds. How has she lost all that weight? Simple, no questionable diet pills this time, it is all about a food-delivery service called Sunfare.

Every year, ovarian cancer takes the lives of 15,000 women. Here is what you need to know about ovarian cancer warning signs and prevention.

Because there are not any telltale symptoms, most cases are not detected until they are at an advanced stage, making prevention all the more essential. Here, three things you can do to reduce your risk.

Ovarian cancer prevention: get your greens A Harvard study found that women who consumed at least 10 milligrams a day of the antioxidant kaempferol were 40 percent less likely to develop the disease. Good sources of kaempferol: broccoli, spinach, kale, and green and black tea.

Ovarian Cancer warning signs: recognize red flags Although none stand out on their own, a combination of symptoms has been identified by top cancer experts. If you experience bloating, pelvic or abdominal pain, a feeling of fullness, and frequent or sudden urges to urinate for two weeks, see your gynecologist, who may perform a pelvic exam or recommend an ultrasound or blood test.

Should you consider the pill? This is a bit controversial, but a study in the Lancet found the longer you take oral contraceptives, the greater your protection against the disease. Using them for 15 years may cut your risk in half. [source: Shape]

There is no doubt that tea is one of the best drinks on the planet. After all, it has almost no calories and lots of potentially healthful antioxidants. So drink up. But also realize that plenty of research is still to be done. Here is the scientific scoop on five of the most popular brews.

Green Population studies have found a link between green tea consumption and lower rates of heart disease. Next up: Clinical trials are needed to determine if it is truly a cause and effect.

Mate One human study found that a pill containing concentrated yerba mate, guarana, and rosemary reduced appetite, but there is no evidence yet that drinking mate can replicate the effect.

Black There is conflicting evidence as to whether drinking black tea truly wards off heart disease and cancer, but test-tube studies suggest that it contains compounds that help fight both maladies.

Chamomile The American Academy of Sleep Medicine found little evidence that chamomile helps you fall asleep, as is often claimed. But one study found that its extract may have anticancer properties.

Rooibos Some animal research suggests that this South African tea may provide many health benefits, such as boosting immunity. Large human studies have yet to be conducted. [source: Mens Health]
