Dairy

Milk and other dairy products contain a sugar called lactose. In order for lactose to be effectively digested and absorbed, it must be broken down by an enzyme called lactase in the body. Lack of lactase enzymes results in lactose intolerance, which impairs the ability to digest lactose and leads to digestive symptoms. Lactose intolerance symptoms include: abdominal pain, bloating. diarrhea, gas, nausea,...

The intolerance to lactose is quite common. In fact, lactose digesting problems are thought to affect 65% of the world's population. There are numerous methods for diagnosing intolerance, such as a lactose-tolerance test, lactose breath test, or stool PH test. Avoid dairy products that contain lactose, such as milk and ice cream, if you think you may be lactose intolerant. As they contain less lactose than other dairy products, aged cheeses and fermented foods like kefir may be easier for those with lactose intolerance to tolerate.
