Pelvic inflammatory disease (PID) is a common gynecological infection that results in a considerable number of sick days and costs society a lot of money. In severe cases, the condition may lead to chronic pain and even sterility if it is not treated in time. There are different things that can cause the infection, and the diet plays key role in supporting the immune defense. Here, magnesium deficiency, which is quite common, appears to increase the risk, especially among older women, according to a study that is published in Frontiers in Nutrition.

Menstrual pain can be quite severe, especially among teenagers and young women, but supplementation with vitamin Dseems to reduce the pain, according to a new meta-analysis that is published in Nutrients. Earlier research has shown that fish oil supplements can do the same. Vitamin D and fish oil primarily work by lowering levels of hormone-like compounds called prostaglandins that cause inflammation and are responsible for the painful cramps in the uterus.
