Salty foods cause water retention and can make your usual PMS bloat worse. To reduce overall distention, you’ll want to avoid the saltiest offenders in your diet, including deli and processed meats (like bacon, sausage, and hot dogs), canned soup, pickles, many frozen entrées, and salty condiments like soy sauce, ketchup, and bottled salad dressing. You should also lay off salty snacks like chips and pretzels. Instead opt for low–sodium foods like yogurt, fresh fruit, vegetables, and unsalted nuts and seeds.
