5 Foods That Help Kick PMS to the Curb

While they might not be the most popular fish, sardines are a major superfood. These tiny fishes are virtually mercury-free, and they're very high in omega-3s, the fatty acids that have been shown to reduce menstrual cramping. Remarkably, sardines are also loaded with calcium; the calcium in about three ounces of sardines is equal to that of eight ounces of milk. If sardines are not your thing, opt for salmon instead.
