3.Barley and Rye
Barley is a grain which is commonly found in many cereals and is rich in fibers. It also contains a number of vitamins and minerals such as manganese, molybdenum and selenium. As they are rich in dietary fibers, they can cause bloating in individuals not accustomed to eating high fiber diet whereas gluten in barley is associated with bloating in patients of celiac disease as well as those suffering from gluten intolerance.
Similar to barley are Rye grains which are also rich in fibers and minerals such as copper, phosphorus as well as B complex vitamins. They are similar to barley in that they also cause bloating as are rich in fibers while gluten intolerance in susceptible individuals causes severe bloating and abdominal discomfort. Oats and brown rice are a good alternative source for those unable to tolerate bloating caused by barley and Rye grains.
