Although dietary changes may not stop a period entirely, premenstrual syndrome, or PMS, symptoms may be alleviated by eating plenty of calcium, vitamin D, whole grains and lean proteins, explains WebMD. Fruits, vegetables and foods rich in vitamin B may help to relieve PMS symptoms.
Studies suggest that women who eat foods rich in calcium and vitamin D are less likely to experience PMS, according to WebMD. Calcium sources such as fortified orange juice, low-fat milk, cheese and yogurt are more effective than calcium supplements. As of 2015, it is believed that calcium helps to alleviate anxiety and depression, and vitamin D can have an effect on emotions.
To keep blood sugar levels regulated and prevent irritability, WebMD recommends eating consistent snacks and meals throughout the day. Whole grains and fortified breads and cereals are ideal because they contain plenty of fiber and vitamin B. Because sugar may trigger PMS symptoms, it is a good idea to avoid added sugars whenever possible. Reducing salt intake may help to prevent bloating and uncomfortable water retention.
In addition to dietary changes, reducing stress, exercising and taking supplements may help to reduce PMS symptoms, notes WebMD. Quitting smoking may also help to reduce PMS symptoms, and evidence suggests that women with a healthy body weight are less likely to experience PMS symptoms.
