London: A new study has found a possible link between vitamin D and improved cancer-fighting immunity.
A study conducted on mice found that this vitamin encouraged the growth of a type of gut bacteria that gave the mice better immunity against the disease.
The researchers found that the immune systems of mice that were fed diets rich in vitamin D had better resistance to cancer transplanted into the mice and responded better to immunotherapy treatment.
Scientists were surprised to learn that vitamin D acts on specific cells in the gut, leading to an increase in the number of bacteria called Bacteroides fragillus.
According to the results, the cancerous tumors did not grow much, indicating that this microbe gave the mice better immunity against cancer.
Study senior author Caitano Reyes E. Sousa, from the Francis Crick Institute in London, said that vitamin D can control a microbiome in the gut for a type of bacteria that gives mice better immunity against cancer.
