We all get vitamin D in two ways – from our diet and from exposure to the sun.A lack of this vitamin puts young children at risk of bone diseases like rickets and older children and adults at risk of bone softening. Some European countries experience so-called ‘vitamin D winters,’ with inadequate sunlight for two to six months per year during which vitamin D cannot be made in the skin. Not many foods are rich in vitamin D. So it can be difficult to make up the shortfall through diet.Food-based solutions are being devised to counter the ‘vitamin D winters'.
