A day without sunshine is like a day without milk.
Your body converts Vitamin D into a hormone that regulates the amount of calcium your body uses. If you are not getting enough, this hormone begins leeching it out of your bones in order to keep your body functioning properly. About 10-15 minutes of direct sunshine exposure to your face and arms a few days a week should provide enough Vitamin D. However, there are factors that can inhibit this free solution to a very complex problem.
Geographic areas that lack sunshine
Always wearing sunscreen
Living/working environment that requires mostly indoor activity during daylight hours
Dark skin
Medical conditions such as Chrone’s disease, celiac disease and cystic fibrosis
Age – as we age, kidney function does not convert Vitamin D to the hormone as efficiently
Substituting Vitamin D rich foods with less healthy alternatives such as soft drinks instead of Vitamin D fortified milk
Obesity
Sunlight is not the only source of Vitamin D. Most cow’s milk is fortified with Vitamin D. It is also present in many foods such as fatty fish (salmon, catfish, mackerel, sardines, tuna) cod liver oil, broccoli, tofu and leafy green vegetables.
Vitamin D Deficiency
Although Vitamin D can be obtained by the abundant resource of sunlight, The American Academy of Pediatrics has shown a shocking increase in Vitamin D deficiency affecting the under 21 age group. Adults are also at risk for complications resulting from low Vitamin D levels.
Vitamin D deficiency is often associated with children and a bone softening disease called Rickets. However, adults are also susceptible to many health conditions such as high blood pressure, heart disease, diabetes and osteoporosis because of Vitamin D deficiency. It has been linked to breast cancer and prostate cancer as well as auto-immune diseases such as multiple sclerosis and inflammatory bowel disease. Some preliminary studies have linked Alheimer’s Disease and dementia to Vitamin D deficiency.
Osteoporosis (Vitamin D tests are linked to our Osteoporosis tests)
Vitamin D promotes bone formation and mineralization and is essential in the development of an intact and strong skeleton. At very high levels it will promote the re-absorption of bone. Vitamin D also inhibits parathyroid hormone secretion from the parathyroid gland.
