Recently I had a question about the difference between lactose intolerance and dairy food allergies. In both cases our bodies have an adverse response to dairy products such as milk, yogurt, cheese.
Some people are so sensitive to dairy that they will respond to any foods that contain these products. I thought I would be helpful to explain the differences between these two conditions.
I will start with lactose intolerance. Lactose intolerance is the inability to break down milk or milk products because the body is no longer producing an enzyme called lactase.
Since all mammals only require milk at the beginning of life, as we age our bodies stop producing lactase as we get older. If we continue to eat dairy after our body has stopped producing lactase, we will start having symptoms when we consume dairy.
Have you noticed that in your twenties or thirties, that you and your friends started to notice difficulty with dairy? Without the lactase enzyme, you may experience gas and bloating, diarrhea, and pain in the abdominal region after eating dairy products.
It has been estimated that at least 10 percent of the population may be affected.
Dairy food allergies cause a completely different reaction in the body. With a dairy food allergy, the immune system responds to any dairy products as substances that could potentially do harm to the body.
The immune system responds to dairy products by mounting an immune response against them similar to the way it would mount a response to a bacteria or virus.
Dairy food allergy reactions can be mild or severe. The mild immune response causes a variety symptoms, including sinus congestion and dark circles under the eyes.
There can be other symptoms including itching in the mouth or diarrhea, or abdominal symptoms. This response is what is sometimes confused with lactose intolerance.
I want to note that some milk allergies can sometimes be very severe, causing an anaphylactic reaction.
This reaction begins within minutes or even seconds of exposure to a dairy product. It can rapidly progress to cause airway constriction, skin and intestinal irritation, and altered heart rhythms.
This reaction can be so quick and severe it can completely close the airways and cause death to the individual. Emergency medical attention is needed.
Whether you or your children are experiencing dairy food allergy or lactose intolerance, the best treatment is to avoid consuming dairy products or food containing dairy products.
If you are lactose intolerant and you decide to continue eating dairy, then it would be beneficial to take lactase enzymes while eating dairy. This can reduce the symptoms you experience.
