Vitamin See

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.

Fighting Florets

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. Sulforaphane, as it’s called, inhibits enzymes that allow cancerous cells to grow. Clinical trials are planned to see if the effect is similar in humans.

Caffeine Fix

Your daily tea or coffee might do more than just energise you. Caffeine may act as an antioxidant, a Mexican study reveals. Antioxidants help prevent the damaging effects of free radicals, which have been linked to heart disease and Alzheimer’s. But don’t use this as an excuse to down more fizzy drinks. Brewed coffee has more than double the caffeine, without all the artificial sweeteners.
