Reference Material:
The body also manufactures vitamin D from cholesterol, through a process triggered by the action of sunlight on skin, hence its nickname, “the sunshine vitamin.” Yet some people do not make enough vitamin D from the sun, among them, people who have a darker skin tone, who are overweight, who are older, and who cover up when they are in the sun. Correctly applied sunscreen reduces our ability to absorb vitamin D by more than 90 percent. And not all sunlight is created equal: The sun’s ultraviolet B (UVB) rays—the so-called “tanning” rays, and the rays that trigger the skin to produce vitamin D—are stronger near the equator and weaker at higher latitudes. So in the fall and winter, people who live at higher latitudes (in the northern U.S. and Europe, for example) can’t make much if any vitamin D from the sun.
Sample Answer:
The sunshine Vitamin D can also be manufactured through a process triggered by the action of sunlights on skin. However, some people don’t make enough amount because of their darker skin, overweight, older age or covering up. Moreover, sunscreen greatly reduces our ability to absorb Vitamin D. Finally, Tanning rays known as trigger in the sunlight aren’t globally equal and people living at higher latitudes can’t make much especially in the fall and winter. (74 words)
