For those who just have to eat dairy, even though there are times that symptoms are almost unbearable, the choice is still yours. Sometimes symptoms are quite bearable depending on what type of dairy product is consumed and at what time. If the beloved cheese on the pizza is a must-have, and if the symptoms are just a tiny bit of nausea and a bloated feeling, then maybe the joy of eating the pizza, for some, is worth the discomfort. Just be aware that the discomfort is caused by something going wrong inside your body, and maybe the mild digestive symptoms are only the tip of the iceberg of what is really going on from the inside out. Sensitivities can manifest in seemingly unrelated disease processes such as eczema and asthma. There is also research to show that consumption of an offensive food over time causes trauma to the body that results in a variety of diseases and dysfunctions down the road.
