An orange a day keeps wrinkles away!

An orange a day may actually keep your wrinkles away. An interesting study has revealed that regular intake of foods rich in Vitamin C helps prevent ageing of skin.

Vitamin C, also know as ascorbic acid, is found in a wide variety of fruit and vegetables. Good sources include peppers, broccoli, brussels sprouts, oranges, kiwi fruit, strawberries, tomatoes, leafy greens, papaya, mango, watermelon, cauliflower, cabbage, raspberries and pineapples.

British scientists examined links between nutrient intake and skin ageing in 4,025 women aged 40-74 years using data from the first National Health and Nutrition Examination Survey. All the women had extensive dermatologic examinations designed to evaluate skin wrinkling and other aspects of skin ageing and also completed a survey listing all the foods they ate in a particular day.

Ageing of the skin was defined as having a wrinkled appearance, senile dryness and skin atrophy.

The study by nutritional epidemiologist Maeve C Cosgrove and other researchers found that those who ate plenty of Vitamin C-rich foods had fewer wrinkles than people whose diets contained little of the vitamin. "Vitamin C is an antioxidant that has been shown to play a role in the synthesis of collagen, the protein that helps keep skin elastic. Our findings add evidence to a predominately supplement and topical application-based hypothesis that what we eat affects our skin-ageing appearance," according to Cosgrove.

"This is one of the first studies to examine the impact of nutrients from foods rather than supplements on skin ageing. Diets rich in Omega-6 fatty acid were found to be associated with less skin ageing from dryness and thinning while higher fat diets and those higher in carbohydrates were found to be linked to more wrinkling," Cosgrove added. Vitamin C, a water-soluble vitamin, is important in forming collagen, a protein that gives structure to bones, cartilage, muscle, and blood vessels.
