Abstract
|
|
|
Purpose: The aim of this review is to comprehensively summarize the definition of vitamin D as a nutrient as well as a hormone-like molecule and its new function in prevention of various chronic diseases.
Methods: The review was written by the method for systematic reivew writing. Literatures from the various sources, including research articles, book chapters, proceedings and electronic materials as appropriate, were screened first and then reviewed and analyzed for the review.
Results: Vitamin D was originally considered as the essential nutrient as a vital carbon compound and was first discovered among children with osteomalacia, also known as ricket disease, characterized by poorly calcified bones which were easily bent rather than broken. Since that time, vitamin D has been known as the key nutrient to improve bone health. However, recently emerging study findings have shown that vitamin D acts as the hormone-like nutrient since it is synthesized like a hormone when our body needs and this particular vitamin also acts like a cell signaling ligand which regulates gene expression of various proteins. So far positive effects of vitamin D have been suggested for the action of anticancer, anti-immune function, and anti-cardiovascular disease, as well as antidiabetic function, etc. In this review, the definition for vitamin D as a nutrient vitamin as well as a hormone-like molecule, cell signaling mechanism of vitamin D, and finally the potential role for the prevention of chronic diseases are discussed.
Conclusion: Vitamin D is now being considered as a vital nutrient as a vitamin and as a potential substance for prevention of several chronic diseases.
