Difference between Garlic allergy and intolerance:
Allergy is the reaction of your immune system to mistakenly identified allergens, while tolerance is just the digestive malfunctioning. Garlic leads to an allergy that can lead to heart and respiratory disorders, which may be fatal in some cases. While intolerance may not be as harmful as an allergy, yet it can severely damage the digestive tract if not treated.
In both the cases, whatever you have an intolerance or allergy to garlic, you must stop eating garlic immediately. It is essential to discontinue the use of a particular food item if your body has even the slightest malfunction with it. So a person can distinguish between allergy and intolerance by noting that; allergy leads to anaphylactic spasm or shock, while intolerance leads to digestive disorders.
