10. Food Allergies and Intolerances
Food allergy occurs when there is an allergy to certain foods. It is caused by an abnormal reaction of the immune system that occurs after the ingestion of a certain food. Even a tiny amount can lead to hives, swollen airways, nausea, vomiting, diarrhea, and more.
Some food allergies can be so severe that it causes a life-threatening condition known as anaphylaxis. Food allergy is common and is estimated to affect 6% to 8% of children under the age of 3 years old and about 3% of adults. Some common food allergies and intolerances include soy protein, cow’s milk protein, methylxanthines (theobromine, caffeine, theophylline), nuts, olestra (fat substitute often used in foods such as potato chips), and more.
