What is a food allergy?

Are you the type of person that always says “I’m allergic!” as soon as you hear something on the menu that doesn’t sound appetizing? Well, it’s time to stop crying wolf and learn what a real food allergy is all about.

Introduction

In simple terms, a food allergy is when your immune system overreacts to certain proteins found in some foods, causing symptoms ranging from mildly annoying (like an itchy mouth) to potentially deadly (like anaphylaxis). But there’s more to this condition than meets the eye. Let’s dive deeper.

The Science Behind It All

Food allergies are usually caused by one of eight common allergens: peanuts, tree nuts, milk, eggs, wheat, soybeans, fish or shellfish. When you consume these foods but have an allergy to them (imagine your body is like “hey this isn’t cool! I don’t like this! wahhh!”) , your immune system produces IgE antibodies and histamine in response. This combo can result in various reactions throughout different parts of your body including:

  • Mouth/throat itching
  • Swelling
  • Hives/rash
  • Vomiting/nausea
  • Difficulty breathing/coughing/wheezing

Symptoms typically show up within minutes to hours after eating the offending food(s).

IG who?

Antibodies might not be something you normally think about on a day-to-day basis but they play a very important role when it comes to allergies. The antibodies produced during an allergic reaction latch onto allergens triggering mast cells (which release histamines) leading us down our symtom path creating unwelome houseguests: inflammation and lots o’ mucus!

The Different Types of Food Allergies

Not all allergies are created equal – while most people with food allergies experience the symptoms listed above, the specific reactions can vary depending on which part of your immune system is responsible. For instance, if you have a food sensitivity (like lactose intolerance), it means your digestive system has trouble processing certain foods and may result in bloating or discomfort – but not necessarily serious health issues like anaphylaxis.

Quick Note

A food allergy differs from gluten sensity/ intolerance which is commonly confused with celiac disease. Celiacs who consume wheat products usually will experience inflammation throughout their small intestine leading to nasty side effects over time.

Who’s At Risk?

Essentially anyone could develop a food allergy at any point in their life- they’re pretty unpredictable! But there are generally some risk factors to watch for including:

  • Family history- there appears to be a genetic link
  • Being born in more developed regions
    (unrelated to modernization per se) whereby families regularly use antibiotic treatments, and other germ reducing strategies causing decreased exposure.
    -Giving birth via caesarean section
    -Marketing gimmicks advertising hypoallergenic infant formulas promising reduced allergen risks.
    -No prior exposure; training your body helps sometimes!
    -Pollution?

How Are They Diagnosed?

There’s no one definitive test doctors use when diagnosing food allergies; rather our dear medical staff rely on a combination of tools:

  1. Skin Prick Test
    • involves pricking the skin with tiny doses of potential allergens
    • A variety of ingridients are selected based under hunch that could cause suspectsd allergies,

2.Blood Test:
provides insight into how various antibodies react within the blood regarding reaction levels potentially caused by antigens

3.Oral Food Challenge :
Can take up weeks( oh boy!). During this period patients eat pre-determined amounts og offending item(s).
(As mentioned , its merely helpful for diagnosing food allergens, as in the end all results have to many other factors at play….)

Okay But What About Treatment?

Presently there are no “cures” for food allergies. However, treatment does exist to help manage symptoms and prevent serious reactions from occurring:

  • Avoidance: Seems obvious but avoiding problematic food(s) is THE #1 rule!
  • Epinephrine auto-injectors : Not a yummy treat ,but this bad boy with 2 doses of epinephrine is what doctors always recommend to those severely allergic inclined individuals
  • Medications: antihistamines / corticosteroids

At the end of the day, you might not be able to cure your allergy completely, BUT you can learn how best manage it so that you can still get out there in life an enjoy! So let us embrace our irritants! No more tears over expired epipens (not like we aren’t fully nonchalant about things anyways…)Live your Life – Eat Delicious noms Safely !
