Food Allergy vs. Food Intolerance: What's the Difference?Updated 3 days ago
Food allergies involve an immune system reaction and can be life-threatening, while food intolerances are digestive issues that cause discomfort but are not immune-related. The symptoms, timing, and management of each are very different.
Food Allergies
Food allergies occur when the immune system mistakenly reacts to a specific food protein as a threat.
Key characteristics of food allergies:
- Trigger an immune response
- Symptoms appear quickly, often within minutes
- Can be severe or life-threatening
Common symptoms include:
- Hives or skin rashes
- Swelling of the lips, face, or throat
- Difficulty breathing
- Anaphylaxis
Food allergies require strict avoidance of the trigger food and medical management. Digestive enzymes do not treat food allergies.
Food Intolerances
Food intolerances do not involve the immune system. They occur when the body has difficulty digesting certain food components.
Key characteristics of food intolerances:
- Caused by digestive limitations, not immune reactions
- Symptoms often appear hours after eating
- Symptoms are uncomfortable but not life-threatening
Common symptoms include:
- Bloating and gas
- Abdominal pain or cramping
- Diarrhea or constipation
Unlike allergies, people with food intolerances can often tolerate small amounts of the trigger food without symptoms.
Key Differences at a Glance
Feature | Food Allergy | Food Intolerance |
|---|---|---|
| Immune system involved | Yes | No |
| Symptom timing | Minutes to 1 hour | Several hours later |
| Severity | Can be life-threatening | Uncomfortable but not dangerous |
| Small amounts tolerated | No | Often yes |
| Managed with enzymes | No | Sometimes |
Where FODMAP Intolerance Fits In
FODMAP intolerance is a type of food intolerance, not an allergy.
It occurs when certain carbohydrates are poorly digested and fermented in the gut, leading to symptoms like bloating, gas, and abdominal discomfort. In these cases, digestive enzymes can be helpful.
Enzyme products like FODZYME® work by breaking down specific carbohydrates responsible for FODMAP-related symptoms, helping reduce digestive discomfort without affecting the immune system.
