As the national conversation about healthcare reform continues, there should be a paradigm shift in healthcare practice - working to improve health through prevention rather than mainly managing symptoms.

Physicians long have known the importance of this vitamin in building strong bones. However, research is emerging that suggests vitamin D plays a much broader role in maintaining optimal health. Vitamin D may help in preventing and treating a growing number of health problems -- including diabetes, high blood pressure, osteoporosis, depression, chronic pain, migraines, multiple sclerosis, epilepsy and certain types of cancers.

Nutrition is coming to the fore as a major modifiable determinant of chronic disease, with scientific evidence increasingly supporting the view that alterations in diet have strong effects, both positive and negative, on health throughout life (World Health Org 2003). Dietary adjustments may not only influence present health, but may determine whether or not an individual will develop such diseases as cancer, cardiovascular disease and diabetes much later in life.
