Just like other food intolerances, having a gluten or lactose intolerance can be a major reason for foul, smelly and painful gas. When someone has a sensitivity to food containing gluten, it means they cannot breakdown the protein gluten in certain types of food. When it’s a lactose intolerance, the body cannot breakdown the carbohydrate lactose found within certain foods. But both these intolerances create gas and irritating flatulence within the bowls and digestive system.
