Indulging in yummy treats such as ice cream and soda to cool you down can cause undigested carbs to travel through the intestines, where they fuel the growth of gas-producing bacteria. The fix? Organic apple cider vinegar. Mix one tablespoon of the vinegar to a cup of water and sip it before meals; it will reduce gas flare ups significantly. The credit goes to its malic and tartaric acids, which jump-start digestion so carbs break down before they reach the intestines.
