Vitamin D is a vitamin that sometimes goes unmentioned when discussing essential dietary needs. Good sources of vitamin D are found in fish, milk, and eggs. There are not many foods with an abundance of vitamin D; the body produces it mostly as a result of exposure to sunlight, and in our society, because mant people do not spend a great amount of time outside, they do not receive an adequate supply of the vitamin. If this is the case, you might want to take a supplement. Here are three benefits of having a good amount of vitamin D in your diet:
1. Improved Mood
Exposure to sun naturally stimulates the production of vitamin D in our bodies. Many people suffer from seasonal-affective-disorder in the winter months. This is because their body is not receiving proper amounts of vitamin D. If you walk or run on a treadmill during the summer, try your workout in the great outdoors instead. You will probably find your increased level of vitamin D improving your mood.
2. Increased Calcium
Our muscles, heart, and nerves all need calcium in order to function effectively and to aid blood clotting. Additionally, lower amounts of calcium often lead to low bone mass and osteoporosis. Without vitamin D, you cannot build calcium. It is through this vitamin that the body absorbs calcium and is able to attain longevity.
3. Better Immunity
While many people point to vitamin C as the best supplement to fight sickness, vitamin D just may be the better one. Last year, researchers at the University of Copenhagen found that vitamin D "triggers and arms" the body's T cells. T cells act as agents that find and destroy harmful bacteria and viruses. These T cells are activated by vitamin D, and a deficieny in the vitamin will cause a deficiency in the immune system.
