Most people would confuse food allergies and food intolerance due to its similar symptoms. Food intolerance may cause symptoms such as burping, indigestion, gas, loose stool, nervousness, headache and a feeling of being “flushed”. But food intolerance doesn’t involve the immune system and is unpleasant but is rarely dangerous such as the symptoms caused by food allergies.
the body reacts to food allergy as though the food that a person has taken is harmful to the body. it creates anti-bodies that reacts and fight the allergens or substance in the food that triggered the allergy. when the person comes in contact with food that he/she is allergic with, through by inhaling, eating, or skin contact, the body produces a chemical called histamine to protect itself. this chemical can affect the immune and the cardio-vascular system and cause symptoms such as runny nose, skin rash, tingling in tongue, lips and throat, swelling, abdominal pains and wheezing.
Food allergies are more common in children than in adults.
