10 Common Food Intolerances That Many People Experience

Millions of people around the world suffer from a common problem called food intolerance. Bloating, diarrhea, and other unpleasant symptoms can result from the body being unable to properly digest some types of food. Others might need to completely avoid certain foods, while some people might be able to tolerate them in small amounts. We will examine the ten most prevalent food intolerances in this article, which many people experience. We will explore the science behind these intolerances—from dairy to gluten—as well as the signs they produce and effective management strategies. This article will give you insightful tips on how to improve your digestive health and lead a happier, healthier life, whether you've been dealing with food intolerances for a long time or are simply interested in the subject. So let's start now!


What causes food intolerances?

The body's inability to digest particular food types is what leads to food intolerances or food sensitives. Numerous factors, including a deficiency in digestive enzymes, an immune system reaction, or an abnormality in the gut microbiome, may contribute to this. Lactose, gluten, and fructose intolerances are the most prevalent types of food intolerances. Histamine sensitivity, FODMAP sensitivity, soy sensitivity, corn sensitivity, egg sensitivity, nut sensitivity, and wheat sensitivity are additional types of food intolerances. Although the root causes of these intolerances can differ, they can all result in a similar set of symptoms.

Understanding the difference between food intolerances and allergies

Contrary to popular belief, food allergies and intolerances are two distinct medical conditions. Food allergies are brought on by an immune system response to specific food proteins, as opposed to food intolerances, which are brought on by an inability to digest certain types of food. Food allergies are potentially fatal, and even a tiny amount of the allergen can cause a serious reaction. Food allergies can cause hives, swelling of the lips and tongue, and breathing issues. Contrarily, the signs of food intolerances can include bloating, diarrhea, and abdominal pain but they are typically less severe.

Common symptoms of food intolerances

Depending on the type and severity of the food intolerance, an individual's symptoms can differ from one person to the next. A few typical signs are:

  • Bloating
  • Diarrhea
  • Abdominal pain
  • Gas
  • Nausea
  • Vomiting
  • Headaches
  • Skin rashes
  • Fatigue

These symptoms may appear right away after eating the problematic food or may take several hours to manifest. It can be challenging to pinpoint the problematic food in some situations because symptoms might not appear for a few days.

Top 10 Common Food Intolerances

1. Lactose intolerance

Up to 75% of people worldwide suffer from lactose intolerance, a common food intolerance. It happens when the body has trouble metabolizing lactose, a type of sugar present in milk and other dairy products. This might be as a result of a deficiency in the enzyme lactase, which is required to break down lactose. Bloating, gas, discomfort in the abdomen, diarrhea, and nausea are all signs of lactose intolerance. People with lactose intolerance can try lactose-free dairy options or supplement their diet with lactase before consuming dairy products to manage their condition.

2. Gluten intolerance

Up to 13% of the population experiences gluten intolerance, another typical food intolerance. It happens when the body can't handle gluten, a kind of protein present in wheat, barley, and rye. Bloating, gas, constipation, diarrhea, and stomach pain are some signs of gluten intolerance. Celiac disease, an autoimmune condition that harms the small intestine, can develop from severe cases of gluten intolerance. People with gluten intolerance can try a gluten-free diet, which entails avoiding foods that contain gluten, to manage their condition.

3. Fructose intolerance

When the body has trouble absorbing fructose, a type of sugar present in fruits, vegetables, and honey, it develops a food intolerance known as fructose intolerance. This might be because there isn't enough of the enzyme that breaks down fructose. Bloating, gas, pain in the abdomen, and diarrhea are some signs of fructose intolerance. A low-fructose diet, which involves avoiding foods that are high in fructose, can help people manage their fructose intolerance.

4. Histamine intolerance

Histamine intolerance is a type of food intolerance that develops when the body cannot process histamine, a chemical produced by the body and present in some foods. Aged cheese, fermented foods, and cured meats are examples of foods high in histamine. Headaches, skin rashes, itching, flushing, and diarrhea are some histamine intolerance signs and symptoms. People with histamine intolerance can try a low-histamine diet, which entails avoiding foods that are high in histamine, to manage their condition.

5. FODMAP intolerance

When the body is unable to absorb particular kinds of carbohydrates, it develops a type of food intolerance known as FODMAP intolerance. Wheat, onions, garlic, and beans are just a few examples of the foods that contain FODMAPs, which are short-chain carbohydrates. Bloating, gas, pain in the abdomen, and diarrhea are all possible signs of FODMAP intolerance. People with FODMAP intolerance can try a low-FODMAP diet, which involves avoiding foods that are high in FODMAPs, to manage their condition.

6. Soy intolerance

When the body cannot tolerate soy, a type of legume that is frequently used in many processed foods, it develops into soy intolerance, a type of food intolerance. Bloating, gas, abdominal pain, and diarrhea are some soy intolerance symptoms. People with soy intolerance can try to avoid soy-containing foods or use soy-free substitutes to manage their condition.

7. Corn intolerance

When the body cannot tolerate corn or corn-based products, it results in corn intolerance, a type of food intolerance. Bloating, gas, pain in the abdomen, and diarrhea are all possible signs of corn intolerance. People with corn intolerance can try avoiding foods that contain corn or trying corn-free substitutes as a management strategy.

8. Egg intolerance

When the body cannot tolerate eggs or products containing eggs, it manifests as an egg intolerance, a type of food intolerance. Bloating, gas, pain in the abdomen, and diarrhea are all signs of egg intolerance. People with egg intolerance can try to avoid foods that contain eggs or try egg-free substitutes to manage their condition.

9. Nut intolerance

The inability of the body to tolerate nuts or products made from nuts is known as nut intolerance. Bloating, gas, pain in the abdomen, and diarrhea are all signs of nut intolerance. People with nut intolerance can try avoiding foods that contain nuts or trying nut-free substitutes as a management strategy.

10. Wheat intolerance

When the body cannot tolerate wheat or products made from wheat, it is said to have a wheat intolerance. Bloating, gas, pain in the abdomen, and diarrhea are all possible signs of wheat intolerance. People can try avoiding foods that contain wheat or trying wheat-free alternatives to manage their wheat intolerance.

How to identify your food intolerances

Since the symptoms of food intolerances can be hazy and may not appear right away after eating, diagnosing them can be difficult. Maintaining a food diary is among the best ways to spot food intolerances. This entails keeping a journal of everything you consume, including any symptoms you experience. You might discover a pattern of symptoms over time that appear after eating particular foods. By removing particular foods from your diet and monitoring whether your symptoms get better, you can also determine if you have food intolerances. Although it may take some time, this method can help you identify the foods that are contributing to your symptoms.

Managing food intolerances - diet and lifestyle changes

Although there are a number of approaches that can help, managing food intolerances can be difficult. Eliminating the problematic foods from your diet is one of the most crucial steps. This may entail completely avoiding certain foods or limiting your intake to an amount that your body can handle. Eating a nutritious, balanced diet that is high in fiber and other essential nutrients is also crucial. This may aid in reducing gut inflammation and improving digestion. Digestion problems can also be influenced by dietary changes and lifestyle choices like stress and sleep deprivation. Taking steps to control these issues can help you feel healthier overall and lower your risk of developing food intolerances.
