3. Vitamin D can protect against chronic diseases.
Studies suggest that vitamin D is not only an excellent immune system booster. It can also prevent a lot of autoimmune diseases. These include lupus (various inflammations of the skin), rheumatoid arthritis and even multiple sclerosis. It is now known that people who live closer to the equator tend to suffer from these health issues less frequently. The reason is the abundance of sunshine in those parts of the world. Another fact is that by taking plenty of vitamin D you reduce the risk of developing colorectal cancer. It is still to be estimated how much of the vitamin you need to receive to prevent cancer, but research is now being carried out in order to find out the nutrient’s effect on this issue.
4. Vitamin D strengthens bones and teeth.
Calcium that you receive through food is absorbed due to the presence of vitamin D in your body. The deficiency of the nutrient is one of the reasons why the ageing population suffers from osteoporosis. Kids that do not receive enough vitamin D develop rickets – that’s another condition that makes children’s bones soft and brittle.
