PMS causes bloating and water retention — and so does salt. Ergo, salt can make those problems of PMS worse. It’s best to avoid the saltiest offenders like canned soups and vegetables, deli and processed meats, salty condiments (like soy sauce and bottled salad dressings),and snacks like chips, crackers and pretzels — and of course you’ll want to skip the salt shaker at meal time. Instead opt for foods rich in calcium (reduced–fat dairy products, fortified soy milk, broccoli, tofu, and almonds) which can help beat bloat during this time of the month.
