Food Allergies

What is a Food Allergy?

A food allergy is an overreaction of your immune system to a particular molecule in food. Even the smallest traces can trigger potentially life-threatening symptoms such as anaphylaxis which can cause trouble breathing and extremely low blood pressure. However, not all reactions to foods are allergies, so it is important to understand the difference between food intolerances and food allergies. Food intolerance symptoms typically show up gradually and don’t involve an immune system reaction.

The majority of allergic reactions are caused by eight foods:

  • Cow’s milk
  • Eggs
  • Fish
  • Peanuts
  • Shellfish
  • Soy
  • Tree nuts
  • Wheat

Symptoms of a Food Allergy

Typically, an allergic reaction to food occurs immediately after coming in contact with the protein, but at times the reaction may manifest several hours later. Symptoms include hives or red, itchy skin, stuffy or itchy nose, sneezing, teary eyes, vomiting, diarrhea, stomach cramps, or swelling. Symptom of anaphylaxis include hoarseness, throat or chest tightness, lump in the throat, wheezing, trouble breathing, or tingling in the hands, feet, lips, or scalp. If any of these anaphylaxis symptoms occur, call 911 immediately.

Note from Dr. Langford

I’m not sure if it’s the active outdoor lifestyle of Middle Georgians, but we’re seeing frequent cases of alpha-gal sensitivity. Alpha-gal sensitivity is the delayed reaction to beef, pork, or other mammalian meat. These reactions can be life-threatening, but are inconsistent. This was first described in 2011 and is associated with tick bites of all things.
