Hello everyone, I hope that I will help you out.
Well, gas is produced in intestines and in a human's stomach when food is made into energy for body. It is normal to have gases, all people have them, but there are two types of gases: gas formed after eating vegetables and fruits and gas formed after eating eggs and meat. Usually gas derived from fruits and vegetables do not have an odor, but those formed after eating eggs and meat... well I guess everyone knows. Why is that? Because the bad odor is caused by small traces of gases such as hydrogen sulfide, methane and ammonia which eggs and meat contains. Causes of gas can be a medical condition (bowel disease), foods and beverage and the amount of gas produced varies from person to person, nutritional supplements or medicines also can be a gas cause as a side effect of it, changes in hormones levels are common for women to have bloating (usually before their period), and finally can be even swallowed air which is not burped, swallowed air is going thru digestive tract and it's causing gas.
How can you treat or prevent gas? I strongly recommend you to change your drinking and eating habits. Sometimes gas can be a medical condition and it requires a professional treatment. Well, there are dietary supplements called "beano" it may prevent you from having gases. Also there are people saying that a product which contains simethicone is helping them with gas problems. Simethicone is a medication that dissolves gas bubbles. I don't want to make commercial advertisement here but I've read on the internet people's feedback about medications with simethicone that helped them called Mylicon and Gas X.
Products that you might exclude from your diet due to their classification of "gas-producing foods" are: eggs, wheat, fried or fatty foods, sugar, milk and any other dairy product, packaged foods that contain lactose, beans and even some fruits and vegetables such as (fruits) bananas, melons, prunes, pears, apricots (vegetables) broccoli, onions, peas, cucumbers, asparagus, cabbage. Drinks: beer, red wine and carbonated drinks (and drinks made of fruits mentioned above).
I sincerely hope that at least something here is going to help everyone with the gas problems. Good luck everyone and be healthy!
