hi, does anyone know how to prevent celeac disease? i was told to take some vitamin D in winter time, anyone knows how much should take for a 4 year old?
Celiac is an autoimmune disease. I don't know that you can prevent it - you either have it or you don't, like Type I diabetes, except instead of carbs/sugars being the item to watch for, it's gluten. http://www.celiac.org/ is the Celiac Disease Foundation, where you can learn more.
there are researches were done for the linkage between Celiac, diabetes, and all other allegeries and VD (vitamin D). they seem to related althought there are no strong evidence was drawn but there is no hurt to give some VD in the winter to compensate that as long as it is in the right range.
