Certain seeds, including sesame and mustard seeds (the main ingredient in the condiment mustard), also are common food allergy triggers and considered a major allergen in some countries.
If your symptoms come on after having dairy products, it’s possible you may have lactose intolerance. This means your body can’t digest lactose, a sugar found in milk, yoghurts and soft cheeses. Your GP can usually diagnose lactose intolerance by looking at your symptoms and medical history. Some people have trouble digesting wheat and experience bloating, wind, diarrhoea, vomiting and stomach pain after eating bread. It is possible you are intolerant to wheat products.
Otherwise, the culprit may be a food additive, chemical or contaminant, such as:
- Monosodium glutamate (MSG)
- Artificial sweeteners
- Histamine (found in Quorn, mushrooms, pickled and cured foods, and alcoholic drinks)
- Toxins, viruses, bacteria or parasites that have contaminated food
- Artificial food colours, preservatives or flavour enhancers

Diagnosis of Food Intolerance
It is not easy to determine whether somebody has a food intolerance or allergy because the signs and symptoms often overlap. Certain patterns in the symptoms can help a doctor distinguish between the two. In the vast majority of cases, food intolerance symptoms take much longer to appear than food allergies.
Patients are advised to keep a diary and write down which foods are eaten, what the symptoms were like, and when they appeared. The data in the diary can help a dietician or doctor identify which foods are causing adverse reactions, and what steps to take.
Types of Food Intolerance
Some common Types of food intolerance are:
- Histamine, present in mushrooms, pickles, and cured food
- Additives such as artificial sweeteners, coloring, or other flavorings
Some people experience a reaction after eating bread, but this does not necessarily indicate a gluten intolerance. Anyone who suspects they may have a gluten intolerance should see a doctor before giving up gluten, as cereals can be an important source of various nutrients.
