Food Allergies Q & A

Optimal Health Spectrums

What causes a food allergy?

Food allergies begin when your immune system mistakenly identifies a protein found in food as a threat to your health. Then an antibody is created that recognizes the protein and sends out an alert every time it enters the bloodstream. As a result, histamines are released to help fight the allergen. These histamines subsequently cause the symptoms associated with food allergies.

What are the symptoms of food allergies?

Symptoms occur within minutes to several hours after eating the offending food. Though everyone may have the same symptoms, the severity of each person’s reaction is different, ranging from mild to severe.

Mild symptoms:

  • Itchy mouth or ears
  • Nausea, vomiting, or diarrhea
  • Stomach pain
  • Nasal congestion or a runny nose
  • Sneezing
  • Coughing or wheezing
  • Skin symptoms -- red, swollen rash or dry, itchy patches

Severe symptoms:

  • Swelling of lips, tongue, and/or throat
  • Trouble swallowing
  • Shortness of breath
  • Turning blue
  • Feeling faint or weak
  • Loss of consciousness
  • Chest pain

What are the most common types of food allergies?

Allergies commonly develop during childhood, although they may not appear until you’re an adult. You can develop an allergy to any type of food, but peanuts are the most common cause and only eight types of food are responsible for 90% of all allergies. The eight types of food are: peanuts, tree nuts, eggs, milk, wheat, fish, shellfish, and soy.

What is a food intolerance?

A food intolerance is a delayed inflammatory immune response to common foods. An intolerance can cause a few symptoms that are similar to a food allergy -- nausea, stomach pain, cramps, and diarrhea -- otherwise, the two are different.

Food allergies can cause a life-threatening allergic reaction. Food intolerances can make you miserable and affect the quality of life, but they’re not fatal.

Food intolerances cause systemic problems such as joint pain, fatigue, irritability, and brain fog. They may also show up as behavior problems in children.

Intolerance reactions are often delayed, appearing hours or days after eating the offending food, making them difficult to identify. However, a simple blood test determines your intolerances, helping to guide you in what foods to avoid.
