Low Levels of Vitamin A Increase TB Risk
People with low vitamin A levels who are living with someone infected with tuberculosis (TB) are 10 times more likely to develop the disease than those with high levels of the vitamin. That’s according to Harvard Medical School researchers who conducted a study in Lima, Peru, , results of which were published in Clinical Infectious Diseases.
The study involved 6,000 household members of people diagnosed with TB. While it didn’t find a cause-and-effect relationship between vitamin D deficiency and TB, it suggests that vitamin A supplements could play an big role in reducing the spread of the disease, which is a leading cause of death worldwide.
