Dear listener
Your question about 'Nutrition' got me thinking. I know people
personally who have suffered due to this but I guess not everyone would
understand the challenges till faced with similar circumstances.
Anyways, I did a bit of research and found an article which says
Nutrition Overview. Nutritional information for you and your family
including lots of heart healthy recipes and nutritional foods, special
dietary concerns like celiac sprue, along with guidelines for prenatal
and children
I found this article at
http://medical-health-care-information.com/Health-living/nutrition/index.asp
Maybe you would want to read more about it there. I hope it's helpful
in some way to you.

NEW YORK (Reuters Health) - A large new study suggests vitamin E may help
prevent death from cancer and heart disease in middle-aged men who smoke,
contradicting the findings of some previous studies on the subject.
In a study of 29,092 Finnish men in their 50s and 60s who were smokers,
those with the highest concentrations of the vitamin E in their blood at
the study's outset were the least likely to die during the follow-up
period, which lasted up to 19 years, Dr. Margaret E. Wright of the
National Cancer Institute in Bethesda, Maryland and colleagues report.
There are a number of mechanisms by which vitamin E, also known as alpha-
tocopherol, might promote health, Wright and her team note in the current
issue of the American Journal of Clinical Nutrition. For example, vitamin
E is a powerful antioxidant, while it also boosts immune system function
and prevents tumor blood vessel growth.
But studies investigating blood levels of vitamin E and mortality, as
well as the effects of taking supplements of the vitamin, have had
conflicting results.
In the current study, Wright and her colleagues compared men's levels of
alpha tocopherol at the beginning of the study, before they had begun
taking the supplements, with their mortality over the course of the
study's follow-up period.
Men with the highest levels of vitamin E in their blood were 18 percent
less likely to die than those with the lowest levels, the researchers
found. They also had a 21-percent lower risk of death from cancer, a 19-
percent lower risk of dying from heart disease, and a 30-percent lower
risk of death from other causes.
The optimum concentration appeared to be 13 to 14 milligrams vitamin E
per liter of blood, with higher concentrations offering no additional
benefit.
Because trials of vitamin E supplements have shown no effect on
mortality, the findings don't suggest that they would be beneficial, but
do suggest that people can benefit from getting more vitamin E in their
diet through foods such as "nuts, seeds, whole grains, and dark-green
leafy vegetables," the researchers conclude.
