Vitamin D is part of a group of fat-soluble steroid molecules (secosteroid) having the biological function of increasing intestinal absorption of minerals such as calcium, magnesium, and phosphorus and of regulating the immune and bone metabolism. Let’s discover what are vitamin D foods, their benefits, and what vitamin D deficiency entails.

What is vitamin D?

Vitamin D is a fat-soluble vitamin that is released into our body when it serves and it accumulates in the liver. There are two types:

  • Vitamin D2 (ergocalciferol) which we find in small quantities in vegetables and in greater quantity in mushrooms;
  • Vitamin D3 (cholecalciferol) is, instead, synthesized by the skin through sun exposure.

Vitamin D foods

It is not easy to find vitamin D foods, but there are some foods that should never be missing in our diet.

In summer, sun exposure helps us to receive the right dose of vitamin D naturally but, in winter, it is very complicated.

Foods rich in vitamin D are:

  • Oily fish (salmon, herring, mackerel, and sardines),
  • full-fat yogurt and cheese,
  • cod liver oil,
  • eggs,
  • mushrooms, the only vegetable source of vitamin D.

Vitamin D deficiency

Vitamin D deficiency negatively affects the calcification of bones with effects ranging from rickets for children to bone deformities of various kinds and osteomalacia, which occurs when the bone structure is externally intact but there is insufficient mineral content within the bones.

The lack of vitamin D also makes the teeth weaker and vulnerable to caries.

Vitamin D deficiency may be due to:

  • Inadequate exposure to sunlight
  • Insufficient intake
  • Reduced absorption
  • Abnormal metabolism

Our tips

Spending time outdoors, in the sun, is the best way to get the daily dose of vitamin D you need. Adequate exposure during the summer season allows you to stock up for the winter.
