Many people enjoy eating beans, but they also know that they will more than likely cause them some discomfort due to gas. So why do beans give you gas? There are very real reasons why this happens and it can mainly be contributed to the amount of sugars that can not be digested. Once the beans hit the colon through the digestion process, the sugars that are contained in the beans are not broken down and cause the uncomfortable feeling of gas. Did you know that if you eat beans on a regular basis, you can actually stop this process over time? If you want to avoid gas from beans all together, eat them daily so you build up an immunity to this embarrassing little fact.
