Even cheese and ice cream can be found with the enzyme included. Lactose intolerance can be treated fairly easily with enzyme pills (Lactaid) or milk products that have this enzyme added. There is a specific breath test that can be used to diagnose this condition. A patient with lactose intolerance may experience bloating, gas and flatus, and diarrhea after eating foods these foods. Lactose intolerance is an inability to properly digest milk and other lactose products such as cheese and ice cream. Examples of this are lactose intolerance and celiac disease. While true allergies to food are often difficult to define, there are a variety of conditions that can cause intolerance of certain foods. Patients with celiac disease may malabsorb macronutrients and become ill. Celiac disease involves an allergy or sensitivity to gluten, which is found in wheat. The eight most common food allergens are milk, wheat, soy, shellfish, fish, peanuts, tree nuts, and eggs. Common gastrointestinal reactions are abdominal pain, nausea, vomiting, and diarrhea. The gastrointestinal reaction is to rapidly get rid of or neutralize the irritant or the allergen. The digestive tract is the first line of contact to food, so it is where allergic reactions originate. Some people can have very severe reactions to those foods if they are allergic. Some of the most common food allergies are peanuts, milk, soy, shellfish, fish, nuts, and eggs. These people have low levels of the enzyme lactase, which prevents the lactose sugar from being broken down. An example of food intolerance is when someone has bloating and diarrhea after consuming lactose. More commonly, people have intolerances to foods, rather than allergies. Thus, celiac is classified as a disease of an autoimmune reaction to gluten. This causes damage to the small intestine, which does not allow for absorption of essential nutrients and minerals into the body. Gluten is the protein found in all forms of wheat, barley, rye, and some oats. It is a lifelong autoimmune disorder in which the body creates a toxic response to the ingestion of any type of gluten. Celiac disease is a common problem, affecting 1 in every 133 people in the United States. One of the most common food allergies is an intolerance to gluten, known as celiac disease. An allergy is defined by having an adverse immune response to a food protein. Although adverse food reactions are common, true food allergies are only present in 3 - 4 percent of adults. Many patients feel they are allergic to a food product because they had some sort of reaction after eating. In the digestive tract, symptoms include nausea, vomiting, abdominal pain, odynophagia (painful swallowing), diarrhea, or any combination of these symptoms. Symptoms are usually acute, but can be chronic and include the gamut of allergic responses in the entire body. Of note, those with peanut and tree nut allergies are unlikely to outgrow them, including the recently increasingly prevalent sesame allergy. In adults, shellfish, peanuts, tree nuts, fish, and egg are the most common. Many children who demonstrate allergy to milk protein outgrow them. What are the most common food allergies, and how do they affect digestion?įood allergies are estimated to affect 6 to 8 percent of children in the United States and 3 to 4 percent of adults. Everyday Health: The rates of food allergies continue to rise.
