Vitamin D - October 2017

Winter Blues, Winter Flus: A simple explanation

By Dr. Tamara Browne, Penticton, BC

Vitimin D is know as the winter sunshine supplement - floers by a blind with sun peeping in

In northern climates vitamin D deficiency is common due to the fact that the sun’s rays are angled to such an extent that the UVB portion of these rays is filtered out. The UVB rays stimulate the biological production of active Vitamin D, D3. Although, in the summer a person produces about 20 000 IU of vitamin D in just 20 minutes, in the Canadian winter we produce virtually none, even if we do expose our skin to the sun (not likely!).

So how does this affect us?

Seemingly the effect is significant according to some recent research. Vitamin D deficiency has been linked to a myriad of health problems which occur more routinely in the winter than any other season or which occur more readily in Northern climates in general.

For instance, viral and bacterial infections including the Flu occur more in the winter. It has been discovered that Vitamin D turns on genes that boost production of antimicrobial peptides called cathelicidins which destroy viruses, bacteria, and other germs.

Low vitamin D levels are also associated with an increased risk of cancer, seasonal affective disorder (SAD), osteoporosis, rickets, multiple sclerosis, high blood pressure, metabolic syndrome, diabetes, and obesity. In elderly people this deficiency is linked with weakness, an increased chance of developing macular degeneration, and a 2.5 times increased risk of death.

Testing is available to determine your Vitamin D status. Recommended supplemental intake during fall and winter is 1000-2000iu per day of vitamin D3. Dietary sources of active vitamin D are scarce and include some fatty fish (herring, salmon, sardines), fish liver oils, eggs from hens that have been fed vitamin D, and fortified milk and infant formulas. Other dairy products such as cheese and yogurt are not usually fortified with vitamin D.

Wellness Tip
Running Shoes
Research indicates that all running shoes lose about 30% - 50% of their shock absorbency after 250 to 500 miles of use. Type of shoe, brand or price doesn't seem to make much difference. Remember, the real investment you make is in your health. The shoes are a means to your ends. Protect feet, knees and back by periodically replacing older shoes based on your mileage and overall use.
