New studies show that taking more vitamin D than recommended may reduce the risk of Covid-19, especially in people of color.
According to a new study published in the Journal JAMA Open Network Reportedly, taking more vitamin D than recommended may reduce the risk of Covid-19 disease, especially in black people.
Researchers at the University of Chicago found data from 4,314 people who took the corona test between March and April 2020. Checked And measured their vitamin D levels.
The researchers found that black people who took the recommended amount (or slightly more) of vitamin D were more than twice as likely to test positive for coronavirus as blacks who took more than the recommended amount of vitamin D.
People with lower than recommended levels of vitamin D were more likely to develop coronary heart disease. No association was found between vitamin D levels and the rate of Quid-19 in white people.
Late 2020 Another study by the University of Chicago on the effect of vitamin D deficiency on coronary heart disease Done Which completes the new research.
The researchers sought to answer the question of whether an increase in vitamin D beyond what is considered “sufficient” for the body’s health could protect a person against coronary heart disease.
People of color are more prone to vitamin D deficiency, and this is one of the possible reasons why they become more ill. The human body naturally produces vitamin D when exposed to sunlight. In colored people, the process of producing vitamin D takes longer because their skin has more melanin. This pigment blocks the sun’s ultraviolet rays.
However, the report cites systematic racism, from less access to health care to social and economic resources, as another reason for the high incidence of coronary heart disease among Americans of color, and that supplements alone cannot make up for deficiencies.
Numerous studies have been conducted on the possible effect of vitamin D in preventing Quid-19 and other diseases that have had conflicting results. For example, a small study in October 2020 Done, Showed that administration of the fortified form and metabolite (Vitamin D Metabolite) to patients with coronary artery disease can significantly reduce the need for intensive care and the risk of death.
Some experts recommend taking vitamin D supplements for the elderly, people with underlying diseases, and people of color. Recommended. According to them, all adults should take 4,000 international units (IU) of vitamin D daily, which is 10 times more than the current dose recommended by health officials. Some research has found no link between vitamin D and improving the condition of Covid-19 patients Have not found.
Of course, vitamin D plays an important role in the health of the immune system and can protect the body against some respiratory viruses. Further research could help experts find a clearer answer to the relationship of this vitamin with Covid-19.
