Vitamin D

This post will be the start of a new series of blog posts about vitamins and minerals, about their function in the body, sources and benefits. Due to the time of the year and some articles I came across in newspapers and other media, I would like to start this series of posts with Vitamin D.

But why do we need vitamin D and what are the health benefits?

Vitamin D has several important functions within the body, but mostly promotes the absorption of calcium and phosphate and therefore has a direct impact on bone and tooth health. Additionally, together with Calcium vitamin D can prevent osteoporosis. Furthermore, according to leading scientists, vitamin D shows breast, colon and immune health.

What are sources of vitamin D?

According to the NHS, most of the vitamin D is produced under the skin when exposed to sunlight. However, this is not the only source. According to the Office of Dietary Supplements (ODS) in the US, vitamin D can be also found in the following foods:

  • oily fish, such as tuna, salmon, mackerel and sardines
  • eggs
  • milk
  • fortified cereals

Sardines at Amanzimtoti in June 2007

However, with a balanced diet and enough sun exposure it is possible to maintain a healthy amount of vitamin D in our bodies.

Who might be at risk not having enough vitamin D?

According to the ODS, they are certain groups of people who are more likely to have a vitamin D deficiency.

  • breastfed infants
  • elderly people
  • people with dark skin
  • people with a lack of sun exposure
  • obese people

Looking at all the above facts that I have obtained from various reliable sources, it seems like that people living in Britain might be one of the risk groups to have a vitamin D deficiency, because I am sure that there are not many people who eat the above mentioned foods regularly and get enough sun exposure during the autumn and winter month. Therefore, why not give it a try with supplements…
