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.Our Paleolithic ancestors ate a more vitamin C-rich diet than modern humans do. Since vitamin is non-toxic and cheap, taking supplements is probably beneficial or at worst, a waste of a little money.
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. Read more
