Vitamin D is an important factor that helps the body absorb calcium and phosphorus, essential minerals to maintain bone density. When vitamin D is deficient, the ability to absorb calcium is reduced, leading to osteoporosis in adults and rickets in children.
According to the World Health Organization (WHO), vitamin D deficiency is one of the main causes of osteoporosis in the elderly, increasing the risk of bone fractures and seriously affecting the quality of life.
In addition, vitamin D plays an important role in regulating the immune system.A study published in The British Medical Journal, BMJ shows that vitamin D deficiency can increase the risk of acute respiratory infections.
In particular, vitamin D supplementation helps reduce the incidence of disease in people with low vitamin D levels. This shows that vitamin D not only supports immunity but can also contribute to protecting the body from infectious diseases.
Vitamin D deficiency is also associated with an increase in chronic inflammatory diseases, which have negative effects on long-term cardiovascular health.
In pregnant women, vitamin D deficiency can lead to many serious complications such as preeclampsia, gestational diabetes and low birth weight.According to a study in the American Journal of Obstetrics and Gynecology, adequate vitamin D levels during pregnancy help reduce the risk of these complications, ensuring healthy fetal development.
The negative effects of vitamin D deficiency are undeniable.To maintain overall health, people need to supplement vitamin D through exposure to sunlight, foods rich in vitamin D such as salmon, egg yolks, fortified milk, and use functional foods when necessary.
Maintaining optimal vitamin D levels not only helps protect the skeletal system but also contributes to improving immune health, cardiovascular health, mental health and cognition.
