Food intolerances are sneaky little things that can wreak havoc on our bodies without us even realizing it. One day, you’re enjoying your favourite meal, and the next, you’re bloated, uncomfortable, and wondering what on earth went wrong. If you’ve been struggling with digestive issues, fatigue, or skin problems, food intolerances might be to blame. But don’t worry! In this article, we’ll discuss everything you need to know about food intolerances—how to spot them, manage them, and ultimately take back control of your health.
What is a Food Intolerance?
It is important to note that food intolerances are not the same as food allergies. While a food allergy triggers an immediate immune system reaction (often quite severe), a food intolerance tends to have more subtle effects. It happens when your body struggles to break down certain foods due to a lack of specific enzymes or a sensitivity to certain chemicals. These reactions are delayed and can take hours or even days to appear, making them tricky to pin down.
Common Symptoms of Food Intolerance
The symptoms of food intolerance can be a bit of a puzzle. They often overlap with other health issues, making it difficult to pinpoint the root cause. However, if you frequently experience discomfort after eating certain foods, a food intolerance could be the culprit. While the symptoms can vary widely from person to person, there are several telltale signs that commonly point to a food intolerance.
Digestive problems
Digestive issues are the most common symptom of food intolerance. Bloating, gas, stomach pain, diarrhoea, or constipation are all signs that your body is struggling to process something you ate. These symptoms can appear a few hours after eating or may even be delayed by a day or two, which can make it hard to link them to specific foods. Many people mistake these signs for irritable bowel syndrome (IBS), but food intolerance could very well be the underlying issue. If you notice these symptoms regularly, especially after consuming specific food groups like dairy or gluten, it’s time to take a closer look at your diet.
Headaches or migraines
Do you find yourself reaching for painkillers after certain meals? Headaches and migraines can sometimes be triggered by food intolerances, particularly to substances like gluten, histamines (found in aged cheeses and wine), or certain additives and preservatives. Unlike other food-related symptoms, headaches often don’t seem immediately connected to what you’ve eaten, which can make this symptom particularly tricky to identify. But if you notice a pattern of headaches shortly after meals or later in the day, it could be worth exploring potential food intolerances.
Skin issues
Your skin is one of the first places where signs of food intolerance can show up. Skin reactions like eczema, hives, or acne flare-ups may be your body’s way of telling you that it doesn’t agree with something you’ve eaten. For instance, dairy and gluten intolerances are notorious for causing skin problems, as they can lead to inflammation that shows up as redness, itchiness, or rashes. If you’ve been battling unexplained breakouts or skin irritation, especially after certain meals, it might be time to evaluate what’s on your plate.
Fatigue and brain fog
Ever feel completely drained or mentally foggy after a meal? This isn’t just the typical post-lunch slump—it could be a sign of food intolerance. When your body has trouble digesting certain foods, it can affect your energy levels and mental clarity. Some people report feeling extremely tired, sluggish, or even struggling to concentrate after consuming specific trigger foods like gluten, sugar, or dairy. This fatigue can last for hours or even the entire day, making it hard to get things done and enjoy life. If you frequently feel like you’re dragging through the day after eating, food intolerance could be playing a role.
Joint pain
Joint pain is another symptom that’s often overlooked in connection with food intolerance. Inflammation is the key here—foods like gluten and dairy have been known to trigger inflammation in some individuals, leading to discomfort and stiffness in the joints. If you experience recurring joint pain without any clear cause, and especially if it seems to get worse after eating, food intolerances might be contributing to the inflammation. Over time, this constant irritation can affect mobility and overall well-being, making it crucial to identify and address any food-related triggers.
Other less common symptoms
In addition to these common signs, food intolerances can also cause less obvious symptoms like nasal congestion, heartburn, or mood swings. Some people might even experience symptoms such as dizziness, palpitations, or even a restless night’s sleep after consuming foods that don’t sit well with their bodies. Because food intolerances often show up in unexpected ways, it’s important to stay attuned to your body’s reactions and consider food as a potential trigger if symptoms occur repeatedly after meals.
Now, these symptoms can be caused by various health conditions, so don’t jump to conclusions. But if they tend to crop up after eating, it’s worth considering that food intolerances could be at play. Keeping track of what you eat and how you feel afterwards can help you uncover the foods that may be causing your discomfort.
Common Food Intolerances
Certain foods are notorious for causing intolerances, and if you’re trying to figure out which ones might be triggering your symptoms, it’s often helpful to start with the usual suspects. These are the foods that, for various reasons, our bodies may have trouble digesting or reacting to. Below, we’ll dive deeper into some of the most common food intolerances and how they affect the body.
Lactose
Lactose intolerance is one of the most widespread food intolerances, especially among adults. Lactose is a sugar found in dairy products like milk, cheese, and yoghurt. To properly digest lactose, your body needs an enzyme called lactase, which breaks it down in the small intestine. However, many people either don’t produce enough lactase or stop producing it as they age, leading to digestive problems. Symptoms like bloating, diarrhoea, stomach cramps, and gas can start anywhere from 30 minutes to a few hours after consuming dairy. While some people can handle small amounts of dairy, others may need to avoid it completely. Thankfully, lactose-free alternatives like almond milk, soy milk, and lactose-free dairy products are widely available.
Gluten
Gluten is a protein found in wheat, barley, and rye, and it can be a major problem for people with gluten intolerance or sensitivity. Gluten intolerance is especially serious for those with celiac disease, an autoimmune disorder where ingesting even tiny amounts of gluten can damage the small intestine. However, even people without celiac disease can experience digestive issues like bloating, diarrhoea, and stomach pain when consuming gluten. Some may also experience fatigue, brain fog, or headaches, which can make pinpointing gluten as the culprit tricky. A gluten-free diet is the best way to manage symptoms, and with the growing availability of gluten-free products, it’s easier than ever to avoid gluten in your everyday meals.

Histamines
Histamines are naturally occurring compounds found in various foods like aged cheeses, red wine, smoked meats, and fermented products like sauerkraut and kombucha. While histamines play a role in immune responses, some people have trouble breaking them down because of a deficiency in an enzyme called diamine oxidase (DAO). As a result, histamine levels can build up and lead to symptoms such as headaches or migraines, flushing, hives, nasal congestion, and digestive discomfort. If you notice these symptoms after eating certain foods, you might be sensitive to histamines. Reducing or eliminating histamine-rich foods from your diet can help, and in some cases, DAO supplements might be useful to aid digestion.
Fructose
Fructose is a type of sugar found naturally in fruits, honey, and some sweeteners like high-fructose corn syrup. People with fructose intolerance, also known as fructose malabsorption, have difficulty absorbing fructose in the small intestine, which leads to it being fermented by bacteria in the gut. This fermentation process produces gas, causing symptoms like bloating, gas, diarrhoea, and stomach pain. If you frequently experience digestive discomfort after eating fruit, juices, or sweetened products, fructose could be the trigger. A low-fructose diet, which limits certain fruits and sweeteners, can help reduce symptoms.
Food additives
In today’s world, processed foods often contain a variety of artificial ingredients like colours, preservatives, and sweeteners. While they’re added to improve shelf life, taste, or appearance, some people have trouble digesting these additives, which can lead to symptoms like headaches, skin rashes, digestive issues, and even mood changes. Aspartame, MSG (monosodium glutamate), and sulfites (found in wine and dried fruits) are common additives that can cause reactions in sensitive individuals. If you suspect food additives might be causing your symptoms, it’s important to read labels carefully and stick to whole, unprocessed foods whenever possible. By doing so, you can avoid unnecessary additives and keep your diet clean and symptom-free.
Other common intolerances
- Soy: Found in many processed foods, soy is another common culprit for food intolerances. It can cause digestive upset and, in some cases, skin reactions.
- Eggs: While egg allergies are well known, egg intolerance is more about digestive discomfort and may cause symptoms like bloating or cramps after consuming eggs.
- FODMAPs: These are a group of short-chain carbohydrates that are poorly absorbed in the small intestine. Foods high in FODMAPs (like onions, garlic, beans, and certain fruits) can cause symptoms like bloating, gas, and stomach pain in people with irritable bowel syndrome (IBS) or FODMAP intolerance.
Understanding these common food intolerances is the first step in taking control of your symptoms and improving your overall health. If you suspect one or more of these foods might be causing problems, consider working with a healthcare provider or nutritionist to identify your triggers and create a tailored diet plan.
How to Identify a Food Intolerance
Identifying a food intolerance can be a bit like solving a mystery. It requires patience, awareness, and sometimes a bit of trial and error. Here are some practical steps you can take:
1. Keep a Food Diary
Start by tracking everything you eat and drink, along with any symptoms you experience. Write down the time you ate and the type of reaction you had. Over time, patterns may start to emerge. Maybe you’ll notice that every time you have pizza, you feel bloated and sluggish the next day. Or perhaps you get a headache after having a glass of wine. This can help you pinpoint specific triggers.
2. Try an Elimination Diet
An elimination diet is one of the most effective ways to identify food intolerances. It involves removing common trigger foods from your diet for a period of time—usually about 2-4 weeks—then slowly reintroducing them one at a time. Start with the basics by cutting out foods like dairy, gluten, soy, and processed sugars. Gradually reintroduce each food and observe how your body reacts. If symptoms return, you’ve likely found your trigger.
3. Consider a Breath Test
For certain food intolerances, like lactose or fructose intolerance, there are medical tests available. A breath test measures the gases your body produces after consuming a specific sugar, which can indicate whether your body is properly digesting it.
4. Blood Tests
Although blood tests are more commonly used to detect food allergies, some healthcare providers might use them to assess your immune system’s reaction to certain foods. It’s not always the most reliable method for intolerance, but it can be useful in some cases.
How to Manage Food Intolerances
Once you’ve identified your food intolerance, it’s time to figure out how to manage it. The good news? With a few adjustments, you can enjoy a symptom-free life without feeling deprived.
1. Avoid Trigger Foods
The simplest way to manage food intolerances is to avoid the foods that cause your symptoms. This might sound obvious, but it’s often easier said than done—especially if your trigger foods are common in your diet. Start by learning how to read food labels and understanding where your triggers might be hiding (for example, gluten is often found in processed foods). Keep your kitchen stocked with safe alternatives, and plan ahead for meals when you’re dining out.
2. Opt for Substitutes
These days, there are plenty of substitutes for common intolerances, so you don’t have to feel like you’re missing out. Lactose-free milk, gluten-free bread, and low-histamine diets can allow you to enjoy meals without the unpleasant aftermath. Explore your local health food store or check out recipes online to find alternatives that work for you.
3. Take Enzyme Supplements
For some food intolerances, you can take enzyme supplements that help your body break down the problematic food. For example, if you’re lactose intolerant, you can take a lactase enzyme before eating dairy. These supplements can be helpful, but they’re not a complete solution, so they should be used with caution.
4. Manage Portion Sizes
Sometimes it’s not about completely avoiding the food, but managing how much of it you consume. People with fructose intolerance, for example, might be able to enjoy small portions of fruit without any issues but will experience symptoms if they overdo it. Pay attention to your body and experiment with portion sizes to see what works for you.
5. Stay Hydrated
Dehydration can exacerbate symptoms of food intolerances, especially digestive issues. Make sure you’re drinking enough water throughout the day to help your body process and eliminate any offending substances. Herbal teas can also soothe digestive discomfort.
