Symptoms can range from minor, such as cold symptoms, hives, rashes, dizziness, and bathroom issues. To be more serious and life threatening, which includes asphyxiation, fainting, throat tightening, and vomiting.

A Food Intolerance is when the body's digestive system has trouble digesting a food, and exhibits symptoms later on. These are more likely to go away with age.

Symptoms here are more minor, and are more similar to that of a virus. Such as abdominal pain, nausea, diarrhea, migraines/headaches, etc.

These are why food labels are crucial, and required by law to list common allergens and ingredients.

Keep common allergen foods away from each other and the dish you're making, (if it is not required.) Wash dishes and hands the most you can.

It is helpful to be aware and careful with friends or families allergies, inform them if there is any risk involved.

While I or anyone around me doesn't have a food allergy, when I was younger. I went to a school that had to outright ban peanuts and peanut butter in the building.

I am curious of whether or not there are "cures" for food allergies, though I am aware that there are ways to build an immunity.

While I do not know anyone with food allergies, I plan to ask about it with anyone I meet in the future.
