Do certain foods make you feel sick? You’re not alone. Many people experience discomfort after eating, but the cause can be very different. Some reactions are food allergies, while others are food intolerances, and understanding the difference is important for proper treatment, especially if you’re looking for expert guidance at the top allergy & asthma clinic in Kolkata.
What Is a Food Allergy?
A food allergy happens when your immune system mistakenly thinks a food is dangerous. Even a tiny bite can trigger a reaction. This can be serious or even life-threatening.
Food allergy vs food intolerance is a big difference because allergies can affect the whole body and may require emergency care.
What Is Food Intolerance?
A food intolerance is not caused by the immune system. Instead, your digestive system struggles to break down certain foods. It can make you uncomfortable, but it is rarely dangerous. Many people can even tolerate a small amount without major issues.
Food Allergy vs Food Intolerance – Key Differences
Understanding the difference between food allergy and food intolerance helps you take the right steps:
| Aspect | Food Allergy | Food Intolerance |
| System involved | Immune system | Digestive system |
| Reaction time | Within minutes | Often after hours |
| Severity | Can be life-threatening | Mostly uncomfortable |
| Amount needed | Even tiny amounts trigger symptoms | Small amounts may be tolerated |
This is why getting the right diagnosis matters.
Food Allergy Symptoms
If you’re having a food allergy, symptoms often appear quickly. Signs include:
- Hives or itching
- Swelling of lips, tongue, face, or throat
- Difficulty breathing or wheezing
- Severe stomach pain, nausea, or dizziness
- Anaphylaxis – a dangerous emergency
At our allergy & asthma clinic in Kolkata, we see these symptoms regularly and provide immediate guidance and support.
Food Intolerance Symptoms
Food intolerance symptoms come more slowly and are usually related to digestion:
- Bloating and gas
- Stomach cramps
- Frequent bowel movements
- Tiredness, dull headaches
- Mild or occasional skin discomfort
These symptoms can affect daily life but are not usually dangerous.
Types of Food Allergies
Common foods that trigger food allergies include:
- Milk
- Eggs
- Peanuts
- Tree nuts
- Soy
- Wheat

These make up most diagnosed allergy cases.
Types of Food Intolerances
Common causes of intolerance include:
- Lactose in milk

Your body may struggle to digest these ingredients.
