Extra C Gets an “F”

>> DRUG RUNNER Don’t bother dosing uo on Vitamin C before exercising. Researchers at Colorado State University who tested mega-doses of vitamin C in hopes of proving that it could improve exercise performance discovered that the vitamin had no effect at all. The study, pulished in the Journal of Applied Physiology, aimed to link huge doses of Vitamin C – 500 milligrams daily plus intravenous infusion – with inceased breathing capacity and heart output. But neither older nor younger participants benefited as hoped, though the vitamin did reduce chemical damage to cells from oxidative stress. The researchers speculate that taking supplements may benefit only people lacking in normal levels of vitamin C. If you’re already getting enough C, megadoses won’t help you at the gym.

Herbal KnowHow

>> SPICE IT UP Garlic contains allylic sulfides, compounds shown in lab studies, to block the growth of cancer cells and kill them outright. While eating the herb raw ensures the full power of these compounds, few people find it appealing. Cooked garlic is less pungent and therefore easier to consume. But take not: Unless the herb is chopped or crushed and allowed to stand for at least 10 minutes before cooking, heat will destory much of the enzyme that unlocks its cancer-fighting compounds. The verdict: It’s your preference. If you cook it, crush it and let it sit while you prep other food.
