What are some fruits that contain vitamin D?
When the sun’s ultraviolet rays strike the skin, it triggers the body to synthesize vitamin D. Twenty to 25 minutes of sun exposure per day normally provide a person with sufficient levels of vitamin D, but many people find it difficult to obtain sufficient vitamin D this way. Those living in latitudes farther from the equator are unlikely to obtain enough vitamin D from sunlight during the winter months because the sun’s rays are not strong enough at that time of year. In addition, conscientious use of sunscreen blocks the skin’s absorption of vitamin D year round, and as skin ages, it is more difficult for it to absorb vitamin D.
