What are Food Intolerances? 

Food intolerances affect millions of people worldwide, and chances are, you or someone you know has experienced the discomfort they can bring. Picture this: you indulge in a delicious meal, only to find yourself feeling bloated, gassy, or experiencing some unpleasant digestive issues afterward. It’s frustrating, right? Food intolerances occur when your body struggles to digest or process certain foods, leaving you with those pesky symptoms.

Food allergies and food intolerances are completely different problems. A food allergy sends your immune system into high alert. The reactions can range from mild itching and hives to more severe symptoms that make it hard to breathe or can even be life-threatening.

If you suspect you have either condition, it’s important to seek guidance from a healthcare professional or allergist who can provide an accurate diagnosis, offer personalized advice, and help you navigate the world of dietary adjustments. Your comfort and well-being are worth it!


There are ten major symptoms you could experience with food intolerance:

  1. Bloating
  2. Gas and Flatulence
  3. Stomach Cramps
  4. Diarrhea or Loose Stools
  5. Constipation
  6. Nausea and Vomiting
  7. Fatigue and Lethargy
  8. Headaches or Migraines
  9. Skin Issues
  10. Mood Changes

Remember, these symptoms can vary in severity and duration depending on the individual and specific food intolerance. If you recognize these symptoms in yourself, it’s essential to consult with a healthcare professional for proper evaluation, diagnosis, and guidance on managing your food intolerances.

Common Types of Food Intolerances

You might’ve heard of lactose intolerance, but there are a lot of other common types of food intolerances lurking in the culinary world.

  1. Lactose Intolerance: Lactose intolerance is one of the most prevalent food intolerances worldwide. It occurs when your body lacks the enzyme lactase, needed to break down lactose, the sugar found in dairy products. Symptoms may include bloating, gas, abdominal pain, and diarrhea after consuming lactose-containing foods like milk, cheese, or ice cream.
  2. Gluten Intolerance (Non-Celiac Gluten Sensitivity): This condition involves an adverse reaction to gluten, a protein found in wheat, barley, and rye. While not as severe as celiac disease, it can cause digestive issues, bloating, diarrhea, fatigue, and brain fog. Avoiding gluten-containing foods like bread, pasta, and baked goods is the primary treatment.
  3. Fructose Malabsorption: Fructose malabsorption occurs when your body has difficulty absorbing fructose, a type of sugar found in fruits, honey, and some sweeteners. Symptoms may include bloating, gas, abdominal pain, and diarrhea after consuming fructose-rich foods or high-fructose corn syrup commonly found in processed foods and beverages.
  4. Histamine Intolerance: Histamine intolerance is characterized by an inability to properly break down histamine, a compound found in various foods and involved in the body’s immune response. Consuming histamine-rich foods like aged cheese, fermented products, or certain seafood can lead to symptoms such as headaches, skin rashes, nasal congestion, and digestive issues.
  5. FODMAP Intolerance: FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) are a group of carbohydrates that some individuals have difficulty digesting. FODMAP intolerance can cause bloating, gas, abdominal pain, and changes in bowel movements. Common high-FODMAP foods include certain fruits, vegetables, grains, and sweeteners.

Remember, this is not an exhaustive list, and other food intolerances may exist. Identifying your specific food intolerances requires careful observation, elimination diets, or consultation with a healthcare professional or registered dietitian. By identifying and managing your food intolerances, you can make informed dietary choices and promote your overall well-being.

Getting Diagnosed 

While it may seem challenging to pinpoint food intolerances, there are several methods and tests available to help you uncover the foods causing your discomfort.

  1. Keep a Food Diary: Start by keeping a detailed food diary, documenting everything you eat and any symptoms you experience afterward. This can provide valuable insights and patterns to discuss with a healthcare professional.
  2. Elimination Diet: An elimination diet involves temporarily removing suspected trigger foods from your diet and then systematically reintroducing them to observe any reactions. Working closely with a healthcare professional or registered dietitian during this process can help ensure accuracy and safety.
  3. Medical Evaluation: Consult with a healthcare professional who specializes in food intolerances, such as an allergist, gastroenterologist or registered dietitian. They will review your symptoms, medical history, and food diary and may recommend additional tests or procedures.
  4. Food Allergy Tests: While food allergies and intolerances are different, some tests used for allergies can also be helpful in diagnosing intolerances. These may include skin prick tests, blood tests measuring specific antibodies, or oral food challenges conducted under medical supervision.
  5. Breath Tests: For certain types of food intolerances breath tests can be performed to measure the gases produced during digestion. These tests can help identify whether you have difficulty breaking down specific sugars or carbohydrates.

Self-diagnosis is not recommended, as it can lead to unnecessary dietary restrictions or overlook other underlying conditions. Seeking professional guidance is crucial for an accurate diagnosis and developing a personalized management plan tailored to your needs. With the right diagnosis, you can take control of your diet, find relief from symptoms, and improve your overall well-being.

Tips to Manage Food Intolerances

Living with food intolerances doesn’t have to be a daunting task. With the right strategies and mindset, you can navigate your dietary journey and reclaim your well-being. Here are some practical tips to help you manage your food intolerances and enjoy a fulfilling and satisfying lifestyle:

  1. Read Food Labels: Become a professional at identifying potential trigger ingredients. Look out for hidden sources of common allergens or intolerant substances, and familiarize yourself with ingredient names or terms that may indicate their presence.
  2. Plan and Prepare Meals: This gives you control over the ingredients and allows you to tailor your meals to your specific needs. Experiment with new recipes, explore alternative ingredients and get creative in the kitchen.
  3. Seek Support and Community: Connect with others who share similar experiences. Online support groups, forums, and social media communities can provide valuable advice, recipes, and emotional support.
  4. Communicate Effectively: When dining out or attending social events, communicate your dietary needs clearly and confidently. Speak with waitstaff or hosts about your food intolerances, ask about ingredient options or consider bringing a dish you know is safe to share at gatherings.
  5. Keep Emergency Supplies: Prepare for unexpected situations by keeping emergency supplies with you, especially if you have severe food intolerances. Carry allergen-free snacks, medication (if prescribed), and allergy alert bracelets or cards to communicate your condition in case of emergencies.
  6. Maintain a Balanced Diet: Ensure you’re meeting your nutritional needs despite dietary restrictions. Work with a registered dietitian to develop a well-balanced meal plan that provides essential nutrients, vitamins, and minerals. Consider supplementation if necessary.

Managing food intolerances can require some adjustments, but it’s worth it for the improved quality of life it can bring. Remember, you are not alone in this journey. Reach out for support, stay informed, and embrace the opportunity to explore new foods and flavors that nourish your body.

By taking control of your diet, making informed choices, and prioritizing self-care, you can thrive with food intolerances and live a fulfilling life. Empower yourself with knowledge, be proactive, and never let your dietary restrictions define you.
