Vitamin D in the diet and health benefits

Vitamin D is naturally present in some foods (e.g. oily fish such as herring, sardines, fish liver oils, eggs, butter) and in a few foods that are fortified with Vitamin D (e.g. .margarine, some cereals, some yoghurts). Vitamin D is fat soluble, therefore advice to eat lower fat diets may contribute to reduced intakes from foods and hence dietary supplementation may be needed. In the UK the background diet provides 3-4 ug /day of Vitamin D and only a little more if oily fish is consumed.
