How to Identify and Manage Food Intolerances - A Comprehensive Guide

Food intolerance is becoming an increasingly serious health concern in India. According to the World Health Organisation, India has the most cases of food allergies and intolerances in high and middle-income countries. Though an allergic reaction can be life-threatening, food intolerance is a relatively mild, primarily digestive, reaction to certain foods and ingredients. But that doesn’t mean it can’t be uncomfortable and disruptive. Understanding food intolerance is essential to managing your health.

What is Food Intolerance?

Food intolerance is the inability to adequately digest, absorb, or metabolize certain food ingredients. While food allergy is a response from the immune system, food intolerance does not involve the immune system and is more typically associated with the digestive system. Symptoms of food intolerance can be similar to those of food allergies but are often less severe. Common symptoms and side effects of food intolerance include abdominal bloating, stomach cramps, nausea, vomiting, headaches, and fatigue.

What Causes Food Intolerance?

The most common causes of food intolerance are the inability to break down certain substances in food, such as lactose in dairy products, gluten in wheat, fructose in some fruits and vegetables, and histamine contained in some fermented foods. In addition, food intolerances may be related to the presence of certain food additives, such as sulfites and monosodium glutamate (MSG). Other potential causes of food intolerance include inadequate production of digestive enzymes, food poisoning, and sensitivities to chemicals contained in food.

How Do You Diagnose Food Intolerance?

It is important to recognize that food intolerance is a diagnosis of exclusion. In other words, it is diagnosed after other food allergies and other possible causes have been eliminated. Diagnosis can be done through a food sensitivity test, which will identify specific foods that are causing an intolerance. Blood tests and skin prick tests, which are used for food allergies, are not effective in cases of food intolerance. Diagnosis of food intolerances is best done through an elimination/provocation test, whereby a suspect food is temporarily eliminated from the diet and then reintroduced to monitor for reactions.

What Can You Do To Manage Food Intolerance?

The first step in managing food intolerance is to identify and eliminate the offending food. This can be done through the elimination/provocation test described earlier. Once the food has been identified, it should be eliminated from the diet or minimized. This can be done through diet modification, such as avoiding certain food groups or by taking supplements or medications to aid digestion. Additionally, some foods can be tolerated in moderation and in combination with other foods.

What Other Factors Can Affect Food Intolerance?

In addition to diet, other factors can contribute to food intolerance. Stress and poor gut health can both increase the likelihood of food intolerances. Research suggests that stress can reduce digestive function and affect the way the body processes food. People with poor gut health, such as those with irritable bowel syndrome or small intestinal bacterial overgrowth, are also more likely to experience food intolerances.

Conclusion

As the prevalence of food intolerances in India continues to rise, a better understanding of the condition and availability of appropriate diagnosis and management are essential to ensure healthy lives. Food intolerance is a digestive disorder that is caused by the inability to break down certain food components. It is diagnosed through an elimination/provocation test and managed through diet modification and supplementation. Additionally, stress and poor gut health can contribute to the development of food intolerance and should be considered in its management.
