Food intolerances are increasingly recognized as a major factor in digestive discomfort, inflammation, and long-term health issues. Unlike food allergies, which involve an immune system reaction, food intolerances occur when the body has difficulty digesting certain foods, often due to enzyme deficiencies, chemical sensitivities, or gut imbalances.
As a private chef in London specializing in nutrition-focused cuisine, I have worked with many clients who require tailored meals due to dietary restrictions. Understanding the most common food intolerances can help you make informed choices about your diet or better accommodate guests with dietary needs.
1. Lactose Intolerance
Lactose intolerance is one of the most widespread food intolerances, affecting millions worldwide. It occurs when the body lacks lactase, the enzyme needed to break down lactose (the sugar in dairy products). Symptoms include bloating, gas, diarrhea, and stomach cramps.
Alternatives:
– Lactose-free dairy products
– Plant-based milks (almond, oat, coconut, soy)
– Hard cheeses and yogurt (often lower in lactose)
2. Gluten Intolerance (Non-Celiac Gluten Sensitivity)
While celiac disease is an autoimmune disorder, gluten intolerance is a separate condition where individuals experience bloating, fatigue, headaches, and digestive discomfort after consuming gluten-containing foods like wheat, barley, and rye.
Alternatives:
– Gluten-free grains (quinoa, rice, buckwheat, millet)
– Gluten-free bread and pasta options
– Naturally gluten-free whole foods like vegetables, meat, and dairy
3. Fructose Intolerance
Fructose is a sugar found in fruits, honey, and some processed foods. Fructose malabsorption happens when the body has difficulty absorbing it, leading to bloating, gas and diarrhea.
Alternatives:
– Low-fructose fruits (berries, citrus, bananas)
– Avoidance of high-fructose corn syrup in processed foods
4. Histamine Intolerance
Histamine is found in aged cheeses, fermented foods, and alcoholic beverages. People with histamine intolerance lack the enzyme diamine oxidase (DAO), leading to symptoms such as headaches, skin rashes, hives and digestive issues.
Alternatives:
– Fresh meats and vegetables (avoid aged, fermented or cured foods)
– Herbal teas and fresh herbs instead of wine and vinegar
5. Caffeine Sensitivity
Caffeine intolerance results in symptoms like rapid heartbeat, anxiety, insomnia and digestive upset. Some people metabolize caffeine slowly due to genetic factors.
Alternatives:
– Herbal teas like chamomile and rooibos
– Decaffeinated coffee or chicory root coffee
6. FODMAP Intolerance
FODMAPs are short-chain carbohydrates found in foods like onions, garlic, beans, and some dairy products. Those with IBS (Irritable Bowel Syndrome) often experience bloating, cramping and diarrhea after consuming FODMAP-rich foods.
Alternatives:
– Low-FODMAP foods like carrots, zucchini, spinach and potatoes
– Lactose-free dairy
– FODMAP-friendly meal plans
7. Sulfite Sensitivity
Sulfites are preservatives found in wine, dried fruits and some processed foods. Sulfite-sensitive individuals may experience asthma-like symptoms, headaches and skin reactions.
Alternatives:
– Fresh, unprocessed foods
– Organic wine or sulfite-free wine options
8. Egg Intolerance
Egg intolerance can cause digestive discomfort, nausea and bloating. Unlike an egg allergy, it does not involve the immune system but rather difficulty digesting proteins in eggs.
Alternatives:
– Plant-based egg substitutes (flax eggs, chia eggs, aquafaba)
– Dairy-free baked goods without eggs
9. Soy Intolerance
Soy intolerance results in bloating, nausea and digestive distress. Soy is widely used in processed foods, making it a difficult ingredient to avoid.
Alternatives:
– Coconut aminos instead of soy sauce
– Almond or oat milk instead of soy milk
– Legume-free plant proteins
10. MSG Sensitivity (Monosodium Glutamate)
MSG is a flavor enhancer used in many processed and restaurant foods. Some people experience headaches, sweating, nausea and chest pain after consuming foods high in MSG.
Alternatives:
– Cooking with natural umami-rich foods (mushrooms, tomatoes, seaweed)
– Avoiding processed foods and fast food containing MSG
11. Nut Intolerance
Nut intolerances can cause digestive issues, while nut allergies can be severe or life-threatening. Some individuals react to certain nuts while tolerating others.
Alternatives:
– Seeds like sunflower or pumpkin seeds
– Coconut-based products
– Nut-free spreads like tahini
12. Dairy Protein Intolerance (Casein and Whey)
Unlike lactose intolerance, casein and whey intolerance occurs when the body has difficulty digesting dairy proteins. This can lead to inflammation, digestive discomfort and mucus build-up.
Alternatives:
– Dairy-free cheeses made from coconut, cashews or almonds
– Plant-based protein sources like pea protein and hemp protein
