Face it: a bad diet can have ugly consequences. Scientists at NYU report that high-glycaemic foods, such as rice,

For a healthy face (and body), limit your carb intake to no more than 40% of your total daily kilojoules and eliminate high-glycaemic foods, says Valerie Berkowitz, director of nutrition at the Center for Balanced Health.
