Carrots aren’t the only orange food that may help your eyesight. According to a Journal of Neuroscience study, vitamin C may protect you from eye diseases such as glaucoma. The nutrient may help maintain normal activity of nerve-cell receptors on the retina, according to the study authors. If you’re 19 or older, the USDA recommends 90 milligrams of C a day, about the amount in one navel orange.
Broccoli’s a killer side dish. Here’s why: an Oregon State University test-tube study reveals that a phytochemical in broccoli may kill prostate-cancer cells.

Brewed coffee has more than double the caffeine, without all the artificial sweeteners.
