Haven’t you wondered why osteoporosis is less in black than the Caucasians, it is simply because we have more sunshine. Now let’s see how it works!
Your skin has a lipid-based substance called 7-dehydrocholesterol. Ultraviolet rays in sunlight convert 7-dehydrocholesterol to vitamin D. This circulates in your blood and is used with calcium and phosphate in the formation and maintenance of bone. Calcium is needed by the body for formation of strong bone, but it cannot be utilized in the body if vitamin D is absent or lacking. People rarely consume food rich in vitamin D and this poses a big problem to the utilization of calcium in the body. Having known that sunlight gives vitamin D, why not go and let the sun hammer you wella! (Remember early morning sun is preferable).
