5. The Science Behind Vitamin D and Food

Understanding the scientific aspects of vitamin D and its interaction with food can help you make informed dietary choices. This section delves into the research and mechanisms behind vitamin D absorption and utilization.

5.1 Vitamin D Synthesis and Metabolism

Vitamin D synthesis begins in the skin when exposed to UVB radiation. This process converts 7-dehydrocholesterol to previtamin D3, which then isomerizes to vitamin D3 (cholecalciferol). Vitamin D3 is transported to the liver, where it is converted to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol. Calcidiol is the major circulating form of vitamin D and is used to assess vitamin D status.

In the kidneys, calcidiol is converted to 1,25-dihydroxyvitamin D [1,25(OH)2D], also known as calcitriol, which is the active form of vitamin D. Calcitriol binds to the vitamin D receptor (VDR) in various tissues, influencing gene expression and regulating calcium absorption, immune function, and cell growth.

5.2 Factors Affecting Vitamin D Absorption

Several factors can affect the absorption of vitamin D from food:
