The scientific world has long before acknowledged the beneficial effects of Vitamin D on bones. Its active compounds can dissolve themselves in fat, and they remain in fat storages throughout the body. From there, they can easily absorb substances that are strengthening the bone structure, such as magnesium, calcium, iron, zinc, and phosphate. However, as of recently, scientists discovered that this compound is also helping immunity system to protect against flu or colds.
On Wednesday, a team of scientists published their results in a paper focused on the advantages of taking supplements of Vitamin D. For their study, they collected and analyzed data from 25 research documents that together included a total of 10,000 participants. The main focus of their research was to find out if this compound can keep a number of respiratory infections at bay.
The lead author of the study, Dr. Adrian Martineau, a professor of respiratory infection and immunity at Queen Mary University, stated that his research didn’t discover any major protective effect. From their studies, the best vitamin D can do to strengthen immunity system against infections by a merely 10% rate. On the other hand, those participants enrolled in the study that showed a deficiency of vitamin D received the best of advantages from their supplement treatment. Their risk of infections decreased by 50%.
Thus, the study advises people to balance their vitamin intake. Any supplement of vitamin D that is lower than recommended can lead to health damage such as osteomalacia that causes muscle aches and bone pains. On the other hand, a surplus of this vitamin can create larger deposits of calcium in the blood which can trigger kidney or heart problems. This is why it is important for anyone who wants a healthy diet to talk to a doctor to find out their ideal intake of vitamins.
The report received negative feedback. Professor Louis Levy, the director of nutrition science at PHE, stated that the study brings no conclusive data that can link vitamin D intake to reduced risk of respiratory tract infections, such as flu, cold or pneumonia. However, other experts in this field took this paper as an important document. They became convinced that this compound is capable of more than taking care of the health of the bones. The lead author of the study wants to persuade authorities in countries with high vitamin D deficiency to promote the consumption of milk.
