Vitamins and minerals are an important part of what keeps our bodies healthy. Like many nutrients our bodies need, we aren’t exactly sure everything that vitamin D does for our bodies. We do know that it is essential for calcium absorption and bone growth, and protects children from rickets and adults from osteoporosis. It also has other functions that are less clear such as regulating neuromuscular and immune function and reducing inflammation. It may also regulate various gene cell activities.
People who live above the 42 parallel (about northern California) where the sun is less intense tend to have a greater vitamin D deficiency, which tells us there is a link between sun exposure and vitamin D. And with the benefits and necessity of vitamin D to our health, there are many recommendations floating around suggesting that a limited amount of sun exposure every day is good for you. Although the sun is a plentiful source of vitamin D, as a dermatologist I also see the many damaging aspects of sun exposure.
Even in Oregon, sun exposure is important to take seriously. The rate of sun-induced skin cancer is increasing, and patients between the ages of 20 and 40 with skin cancer have tripled in the last five years, leading to the assumption that we have become lax in protecting our skin.
We are fortunate to live in the U.S., an affluent society where vitamin D is a plentiful nutrient that can be fulfilled by the food we eat. Vitamin D is found naturally in fish, egg yolks and liver. Many foods such as milk, soy drinks, orange juice, margarine and breakfast cereals are fortified with vitamin D.
Our bones and our bodies are important to take care of. With vitamin D available in so many safe and healthy forms, there is no reason to risk sun exposure. A well balanced diet should take care of your nutrition needs, and inexpensive supplements can be added if needed.
