Let’s talk Food Allergies! You’ve heard the term and maybe even know someone with a food allergy, but what does having a food allergy mean?

What is a Food Allergy?

A food allergy is a potentially life threatening condition where the body’s immune system thinks certain foods are trying to harm it. The body’s immune system mistakenly targets normally, harmless proteins and treats these as a threat . Histamine and other chemicals are released to fight the “invader,” much like the body does with bacteria or viruses.

A food allergy is not a food sensitivity or intolerance. A food allergy does not mean the affected person is a picky or fussy eater.
