Final answer:
immune system. Food allergies occur when the immune system reacts to certain proteins in food as though they were harmful. This can cause a physiological response. Food allergies occur when the immune system reacts to substances in food as though they were harmful 'foreign invaders.'
Step-by-step explanation:
In the case of food allergies, the immune system causes a physiological response to certain proteins present in tree nuts. Food allergies occur when the immune system reacts to substances in food as though they were harmful 'foreign invaders.' In the case of food allergies, the immune system causes a physiological response to certain proteins present in specific foods. The immune system perceives certain proteins as harmful, triggering an immune response. In the context of allergies, the body's immune system produces antibodies, particularly immunoglobulin E (IgE), in response to the allergenic proteins.
In Tyler's situation, where he has a food allergy, his immune system reacts to proteins found in tree nuts, leading to allergic symptoms. These symptoms can range from mild reactions such as itching or hives to severe and potentially life-threatening reactions known as anaphylaxis. On the other hand, food intolerances typically involve the digestive system rather than the immune system. In food intolerances, the body has difficulty digesting certain substances, often due to enzyme deficiencies or other digestive issues. Symptoms of food intolerances may include digestive discomfort, bloating, gas, and other gastrointestinal symptoms. Unlike allergies, food intolerances do not involve an immune system response.
