Hyperactivity, Additives & Vitamin D3 ~ Is there a link?
7 February 2008Study on Hyperactivity and Additives.
The January, 2008 issue of DISCOVER magazine features the 100 top science stories of 2007. One of the scientific events they selected is the 2007 study of food additives and hyperactivity, conducted at the University of Southampton in England. The children, who were drawn from the general population, were placed on a diet that eliminated food dyes and the preservative sodium benzoate. They were given either a fruit juice drink or a drink that contained the additives. Both drinks looked and tasted the same.
The children were observed and tested to determine their level of hyperactivity. When they consumed the drinks with the additives their hyperactivity scores were nearly double compared to when they drank the plain fruit juice. The test design was double blind, which means nobody was aware of when the children consumed the additives and when they did not until the study was completed. The research, published in the September 6 issues of THE LANCET, is considered to be the most well designed to date.

Several new studies on the value of Vitamin D3 continue to add to our knowledge of the many benefits of this vitamin, which was virtually ignored until recently. It appears that most tissues and cells in the body require it in order to function well; this may explain why low levels of D3 have been linked with such a broad range of health problems. The amount of vitamin D needed has been grossly underestimated, according to many researchers, and the Canadian Pediatric Society now recommends that pregnant and breast-feeding women supplement their diet with 2,000 IU of it each day.
MORE ON RECOMMENDED LEVELS OF VITAMIN D.
A new study, published in November, is titled “Molecular basis of the potential of Vitamin D to prevent cancer.” The authors write, “Currently, most experts in the field believe that intakes of between 2000 and 4000 IU will lead to a more healthy level of [the vitamin] that will offer significant protective effects against cancers of the breast, colon, prostate, ovary, lungs, and pancreas.

The November issue of SCIENTIFIC AMERICA carried a comprehensive article on vitamin D, repeating what many researchers are finding: the vitamin is essential for optimum health and the current recommendations are inadequate. The American Academy of Pediatrics recommends a minimum daily intake of only 200 IU for children.
Our bodies will create vitamin D through exposure to sunlight so geography plays a part in the amount of supplementation one would need. People living in Canada and Northern Europe receive insufficient sunlight for most of the year. Those living in Northern Africa, Southern Europe and in all of the United States (including the deep South) still do not receive sufficient sunlight to supply the amount of the vitamin that is needed for good health. John Taylor, PhD, Notes “Vitamin D3 affects the immune system, and anything that affects the immune system affects ADHD.”
