Food allergy and food intolerance are two different conditions, but both can affect your lungs. Food allergies involve your immune system and can cause serious lung reactions, like asthma or even trouble breathing. On the other hand, food intolerance usually does not involve the immune system, but sometimes it can still cause mild respiratory symptoms. Understanding the difference between food allergy and food intolerance in lungs is important for your health. In this blog, we will explore lung reactions to food allergy, respiratory symptoms of food intolerance, and how to manage these issues.
What is a Food Allergy?
A food allergy happens when your immune system reacts to a certain food. Even a small amount of the food can trigger symptoms. Common triggers include peanuts, tree nuts, milk, eggs, fish, shellfish, soy, and wheat. When you eat a food you are allergic to, your body sees it as a threat. As a result, your immune system releases chemicals like histamine. These chemicals can cause symptoms in many parts of your body, including your lungs. According to the CDC, food allergies affect about 8% of children and up to 4% of adults in the US.
What is Food Intolerance?
Food intolerance is different from a food allergy. It does not involve your immune system. Instead, your body has trouble digesting certain foods. Common triggers include lactose (found in milk), gluten (found in wheat), and some food additives. Usually, food intolerance causes stomach problems, like bloating or cramps. However, in rare cases, it can also cause mild respiratory symptoms. For example, some people may cough or have a runny nose after eating certain foods. But these symptoms are usually not severe.
How Food Allergies Affect the Lungs
Food allergies can cause strong reactions in your lungs. For some people, eating an allergen can trigger asthma symptoms. These may include:
In severe cases, a food allergy can cause anaphylaxis. This is a life-threatening reaction that can make it very hard to breathe. The airway can swell, and you may need emergency care right away. According to the World Health Organization (WHO), anaphylaxis can happen within minutes after eating the allergen. Therefore, it is important to know the signs and act quickly.
How Food Intolerance Affects the Lungs
Food intolerance rarely causes lung problems. Most symptoms are related to the stomach or gut. However, some people may notice mild respiratory symptoms, such as:
These symptoms are usually not dangerous. They do not cause swelling of the airway or severe breathing problems. Still, if you notice any new symptoms after eating, it is wise to talk to your doctor.
Key Differences in Lung Reactions
