Study finds mismatch between kids and vitamins

NEW YORK (Reuters Health) - Vitamin supplements are meant to fill-in where diet may be lacking, but a new study finds that U.S. kids may not be getting some of the most needed nutrients from their vitamin pills and the kids taking vitamins may not be the ones who need them the most. Looking at the diets and supplement use of more than 7,000 kids, researchers found that between the ages of nine and 18 many had low levels of certain vitamins and minerals, and few took supplements, while younger kids had adequate levels of most nutrients and were possibly getting too much of some vitamins and minerals. Most children under eight, for instance, got the nutrition they needed from the food they ate, regardless of whether or not they took supplements, the study found. Even with the use of supplements, however, more than a third of children failed to get sufficient calcium and vitamin D. And users sometimes overloaded on essential nutrients such as iron and vitamin A. Zinc and folate were consu...

Smoking mothers' embryos 'grow more slowly

French academics in an IVF clinic took regular pictures of an egg from the moment it was fertilised until it was ready to be implanted into the mother. At all stages of development, embryos from smokers were consistently a couple of hours behind, a study showed.The lead researcher, from Nantes University Hospital, said: "You want a baby, quit smoking". Smoking is known to reduce the chances of having a child. It is why some hospitals in the UK ask couples to give up smoking before they are given fertility treatment. As eggs fertilised through IVF initially develop in the laboratory before being implanted, it gave doctors a unique opportunity to film the embryos as they divide into more and more cells. Researchers watched 868 embryos develop - 139 from smokers.In the clinic the embryos of non-smokers reached the five-cell stage after 49 hours. In the smokers it took 50 hours. The eight-cell stage took 62 hours in smokers' embryos, while non-smokers' embryos reached tha...
