Strictly speaking, it is not a vitamin since human skin can manufacture it, but it is referred to as one for historical reasons. It is often known as calciferol. The major biologic function of vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. It promotes bone mineralisation in concert with a number of other vitamins, minerals and hormones. Without vitamin D, bones can become thin, brittle, soft or misshapen. Vitamin D prevents rickets in children and osteomalacia in adults -- skeletal diseases that result in defects that weaken bones. This book gathers international research on the leading-edge of the scientific front.

"NEW YORK (Reuters Health) - Women who eat greater amounts of plant-based foods and drinks with the naturally occurring flavonoid, apigenin, may have a decreased risk for ovarian cancer, study findings suggest. Apigenin, found in celery, parsley, red wine, tomato sauce, and other plant-based foods may be "particularly beneficial," said Dr. Margaret A. Gates, of Brigham and Women's Hospital and Harvard Medical School, in Boston, Massachusetts. Flavanoids are compounds with antioxidant properties that protect cells against damage by oxygen molecules. In a study that compared flavonoid intake among women with and without ovarian cancer, women reporting the highest apigenin intake had a "borderline significant decrease" in ovarian cancer risk over women reporting the lowest apigenin intake, Gates and her associates report in the International Journal of Cancer."

In an article published online on January 4, 2010 in the Journal of Agricultural and Food Chemistry, Robert Krikorian of the University of Cincinnati, along with his colleagues from the US and Canadian Departments of Agriculture, report that consuming blueberry juice was associated with improvements in learning and memory in individuals with age-related memory decline. The trial enrolled five men and four women over the age of 70 who reported forgetfulness and memory lapses characteristic of early memory decline. Participants were given the equivalent of 2 to 2 ½ cups of a commercially available blueberry juice daily for 12 weeks. Cognitive assessments were conducted at the beginning of the study and during the final week of the trial. At the study's conclusion, learning and recall were improved, and depressive symptoms and glucose levels tended to be reduced. When subjects who received blueberry juice were compared with a demographically matched sample who received a placebo beverage in a companion trial, test scores for learning ability were significantly better.

On an ordinary UK diet, iron is derived about one-third from animal foods, onethird from fortified breakfast cereals and one-third from the rest of the diet. The iron content of common foods is given in Table 40 and the daily iron needs in Table 41. On average, 10-15 mg are consumed each day and the efficiency of absorption is around 10 per cent
