Vitamin D Metabolism
There are two forms of vitamin D – vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is produced in the skin by the action of ultravioiet B (UVB) light on skin cells. Vitamin D2 is plant derived. Both Vitamin D2 and D3 can be obtained from certain foods in the diet or as supplements.
On average, only about 20% of our daily vitamin D intake is obtained from the diet, due to the limited range of food that contains vitamin D. Thus sunlight is usually our major source of Read more
Roles of Vitamin D In The Prevention of Diseases
VITAMIN D is one of the fat-soluble vitamins well known for being essential for skeletal health. Osteoporosis and oste-oporotic fractures are the consequences of poor skeletal health.
Vitamin D affects fracture risk in two ways: by decreasing falls and increasing bone density.
Low vitamin D levels have been associated with lower bone density in adolescents and adults, as well as an increased risk of fracture. This increased risk of fracture may be linked with the fact that vitamin D has direct e Read more

Staying Trim in Youth Pays off in Old Age
Staying trim and healthy when young can lead to a healthier, more mobile old age, US researchers say.
Researchers analysed data on more than 2,800 people aged 70 to 79. They found that women and men who were obese at ages 25 and 50, as well as at the time of the study, scored significantly lower in physical performance tests than those who were normal weight at those ages.
The study also found that men and women who were overweight or obese in early- to mid-adulthood had lower scores than those Read more
Sleep Apnea Increases Accident Risk
People with sleep apnea – a night-time breathing disorder that disrupts sleep – double the risk of being in a serious car crash, a Canadian study finds.
“We were surprised, not only about how many sleep apnea patients’ crashes involved personal injury, but that some patients had fairly mild sleep apnea and were still having serious crashes,” said study author Dr. Alan Mulgrew, of the University of British Columbia Sleep Disorders Programme.
