Foods that help prevent stomach gas include raw honey, pineapple and cabbage. Additionally, herbs such as fennel, flaxseed, cinnamon and peppermint are effective at reducing and preventing stomach gas. Drinking green juices and lots of water are also suggested to prevent stomach gas from forming, according to HuffPost Living Canada.
While cabbage is notorious as a cause of gas, it can actually help reduce it by aiding the digestive process. Eating peppermint leaves or adding them to tea calms the digestive system in the same way as raw honey and ginger. Cinnamon helps the body metabolize fats in the digestive tract, helping the body avoid producing too much gas, according to Huffpost Living Canada.
Avoiding or reducing certain foods from the diet is also helpful in preventing gas from forming. Vegetables such as cauliflower, broccoli and Brussels sprouts produce more gas when being digested. Fruits such as apples, pears and peaches as well as whole grains and bran can aggravate stomach gas problems. These foods are healthy and should not be totally avoided, but reducing their intake helps prevent stomach gas, as explained by WebMD.
Consuming fewer fatty foods, eating slowly, avoiding sodas and getting more exercise are all ways to prevent stomach gas. Adding Beano to foods high in fiber is also a way to prevent them from producing excess stomach gas during their digestion. Over-the-counter medications containing simethicone haven't been proven very helpful, but they can help break up bubbles in gas, as suggested by Mayo Clinic.
