New research shows women with a higher iron intake are less prone to PMS symptoms.

A study conducted by researchers at the University of Massachusetts at Amherst of 3,000 women found those who consumed at least 20 milligrams of iron per day were 30 to 40 percent less likely to be diagnosed with PMS.

Research also saw a link between higher zinc intake and a reduced risk of PMS. Experts say although avoiding unpleasant bloating and irritability sounds great, women should not take more than 45 milligrams of iron a day unless recommended by a doctor.

An unexpected result of the study was that higher levels of potassium appeared to raise the risk of PMS.
