Treatment of Food Intolerance
The treatment of food intolerance focuses on symptom management through dietary modification. Unlike food allergies, which require complete avoidance of the allergen, food intolerance may allow for small or occasional consumption of the trigger food, depending on individual sensitivity.
Avoiding or Reducing Trigger Foods
Identify the problematic food to take appropriate action:
Avoid or limit intake based on tolerance threshold
Choose low-lactose, low-fructose, or additive-free alternatives
Prepare more meals at home to control ingredients and reduce exposure
Use food apps or online databases to identify safe products
For example, those with lactose intolerance may tolerate hard cheeses or lactose-free milk, while individuals with sulphite sensitivity should avoid processed meats and wine.
Dietary Planning and Substitutions
A registered dietitian can help:
Identify safe food substitutes to maintain a balanced diet
Ensure you don’t miss out on essential nutrients (e.g., calcium, fibre, B-vitamins)
Introduce elimination diets safely without excessive restriction
Plan FODMAP-friendly meals if following a low-FODMAP approach for IBS-like symptoms
The goal is to support digestive health without unnecessary food anxiety or nutritional compromise.
Enzyme Supplements
Manage some intolerances with dietary adjustments, enzyme supplements, or medical guidance:
Lactase tablets to help digest lactose
Alpha-galactosidase enzymes for legumes and cruciferous vegetables
Take these supplements with meals to reduce symptoms when completely avoiding the food isn’t practical
You can buy them over the counter, but use them only under medical advice.
Symptom Relief
To manage discomfort:
Use antispasmodics for cramps or bloating (under a doctor’s guidance)
Peppermint oil capsules may relieve digestive discomfort in some individuals
Probiotics might improve gut health over time, although results vary
These remedies are supportive but do not replace dietary changes.
Gradual Reintroduction
Some people can reintroduce small portions of the trigger food after a period of avoidance:
This should be done slowly and methodically
Tolerance levels differ—while one person may tolerate a slice of bread, another may react to a few crumbs
Monitor symptoms carefully and keep your healthcare provider informed
Diagnosis of Food Intolerance
The treatment of food intolerance is personalised and adaptable. With professional guidance and a clear understanding of trigger foods, most people can manage symptoms and maintain a full, satisfying diet.
