Put aside the wrinkle creams and eat an orange instead. Your diet can help your skin stay wrinkle-free and supple.
The participants who ate more vitamin C and linoleic acid (an unsaturated fatty acid) showed fewer signs of skin aging.
Specifically, eating more vitamin C was associated with fewer wrinkles and better skin hydration, while higher linoleic acid intake was associated with better hydration and less skin atrophy (where the skin becomes thinner as it loses collagen). On the flip side, eating more fats and carbohydrates increased signs of skin aging.
The study looked at regular diets (rather than supplements), which means that adding these nutrients to your daily diet really can make a difference. So pack your fridge with foods rich in vitamin C and linoleic acid to cook up some gorgeous grub.
