Rickets News and Research RSS Feed - Rickets News and Research

Rickets is a condition that causes children to have soft, weak bones. It usually occurs when children do not get enough vitamin D, which helps growing bones absorb important nutrients. Vitamin D comes from sunlight and food. Skin produces vitamin D in response to the sun's rays. Some foods also contain vitamin D, including fortified dairy products and cereals, and some kinds of fish.

Study links vitamin D deficiency to accelerated aging of bones

Everyone knows that as we grow older our bones become more fragile.

Maternal vitamin D levels not found to affect children’s bone health

A study of nearly 4000 pairs of mothers and their children in the Children of the 90s study at the University of Bristol has shown that maternal vitamin D levels during pregnancy are not associated with the child’s bone health in later life. The research, published Online First in The Lancet, is the largest ever observational study of the effects of mothers’ vitamin D levels in pregnancy on their children’s bone health, and suggests that UK health guidelines may be overstating the importance of vitamin D supplementation in pregnancy.
