Sorry, you're wrong.

FICTION: "Feed a cold, starve a fever".

If you get the flu, do not deliberately starve yourself. You should actually try and eat something nutritious if you can to help give you energy to fight the virus. It is particularly important to up your intake of foods containing Vitamin C and zinc, both of which have been shown to help maintain the body's defences. If you want to try taking supplements, your pharmacist can advise you. Foods rich in vitamin C include the citrus fruits (oranges, lemons and limes), kiwi fruit, blackcurrants and red peppers. Foods containing zinc include oysters and red meat.
