Table of Contents


Food sensitivities affect a considerable number of people globally. The symptoms of food sensitivity range from mild discomfort to severe digestive issues, skin reactions, and respiratory problems. For some individuals, certain foods trigger their sensitivity, while for others, it can be a broad range of foods. Managing food sensitivities requires identifying these trigger foods and avoiding them. 

This article will discuss the most common foods that trigger food sensitivities and provide practical tips on avoiding them. Understanding these foods and how to avoid them can significantly improve the quality of life for people living with food sensitivities.

Common Foods That Trigger Food Sensitivities

Food sensitivities can be challenging to identify and manage, as certain foods can trigger adverse reactions in sensitive individuals. Common trigger foods include:

Gluten-containing grains

Gluten is a protein found in grains such as wheat, barley, and rye. For people with celiac disease, consuming gluten triggers an autoimmune response that damages the lining of the small intestine. Additionally, some people without celiac disease may experience non-celiac gluten sensitivity, which can cause symptoms such as bloating, diarrhea, and fatigue.

Dairy products

Dairy products

Lactose, a form of sugar present in dairy products like milk, cheese, and yogurt, can be difficult to digest for some individuals leading to lactose intolerance. It is characterized by symptoms such as bloating, gas, and diarrhea. Moreover, proteins present in milk can cause allergic reactions in certain people, resulting in symptoms such as hives, wheezing, and, in severe cases, anaphylaxis.

Soy products

Proteins present in soybeans and soy products like tofu and soy milk have the potential to provoke an allergic response in some individuals. The symptoms of soy allergy can vary from mild to severe and may include itching, hives, and difficulty in breathing.

Nuts and seeds

Nuts and seeds, such as peanuts, almonds, and sesame seeds, have the potential to cause an allergic response in some individuals. Symptoms of the allergy can range from mild to severe and may include swelling, hives, and even anaphylaxis.


Shellfish like shrimp, crab, and lobster are capable of causing an allergic reaction. The symptoms of shellfish allergy can vary from mild to severe and may involve hives, swelling, and breathing difficulties.

Nightshade vegetables

Solanine is a compound present in nightshade vegetables such as tomatoes, peppers, and eggplants. It can incite an immune response in certain individuals. This immune response may lead to symptoms like joint pain, skin rashes, and digestive problems.


Eggs are a frequently encountered allergen that has the potential to provoke an allergic reaction in certain individuals. Symptoms of egg allergy can vary from mild to severe and may include hives, wheezing, and anaphylaxis. Apart from this, some individuals may experience egg intolerance, which can cause digestive issues such as bloating and diarrhea.

In conclusion, it is necessary to avoid trigger foods by individuals with food sensitivities. This can ensure that they are getting all the necessary nutrients and lead a healthy and fulfilling life.

How to Identify Trigger Foods

Food sensitivities can be difficult to identify, as symptoms may not always be immediate or obvious. However, there are several methods to help identify trigger foods that may be causing adverse reactions. Here are four ways to identify trigger foods:

Keeping a food diary

To identify foods that trigger symptoms, it's recommended to maintain a comprehensive food diary. This involves documenting all food and beverages consumed, along with any symptoms experienced such as headaches, bloating, or gas. Over time, by keeping track of food intake and associated symptoms, one can potentially identify patterns and pinpoint trigger foods.

Elimination diet

Another method to identify trigger foods is to follow an elimination diet. This involves removing suspected trigger foods from your diet for a period of time, typically two to four weeks, and then reintroducing them one at a time to see if any symptoms occur. This method can be effective but should be done under the guidance of a healthcare professional.

Food sensitivity tests

Food sensitivity tests, such as IgG antibody testing or ALCAT testing, can also help identify trigger foods. These tests analyze your blood or saliva for immune system responses to various foods. While these tests are not always accurate, they can provide useful information to guide an elimination diet or to identify possible triggers. 

Advanced food intolerance lab (AFIL) test kits can be an effective tool for identifying the specific foods that may be causing sensitivity reactions. These tests use a combination of IgG and IgA antibodies to detect food sensitivities, providing a more comprehensive understanding of a person's food sensitivities than traditional tests.

Working with a healthcare professional

Working with a healthcare professional

Seeking assistance from a registered dietitian or allergist is another option to identify trigger foods. These healthcare professionals can offer advice on how to maintain a food diary, carry out elimination diets, and conduct food sensitivity testing. Moreover, they may administer supplementary tests like skin prick testing to detect allergens.

In conclusion, identifying trigger foods is an important step in managing food sensitivities. Keeping a food diary, eliminating suspected trigger foods, and reintroducing them one at a time can help identify problematic foods. Working with a healthcare professional, such as a doctor or registered dietitian, can also be beneficial in identifying trigger foods and developing a safe and balanced meal plan. 

Tips for Avoiding Trigger Foods

Avoiding trigger foods is an essential part of managing food sensitivities. Here are some tips for avoiding trigger foods:

Reading food labels

To identify ingredients that could trigger your food sensitivities, one helpful tip is to read food labels carefully. Be on the lookout for common allergens like gluten, dairy, soy, nuts, and shellfish. Additionally, take note of any hidden ingredients or derivatives of these allergens, such as whey protein or soy lecithin.

Cooking at home

Cooking at home

By cooking at home, you can have a greater influence on the ingredients used in your meals, enabling you to steer clear of trigger foods and use substitutes that are safe for you. Planning ahead and preparing meals in advance can help you avoid the temptation of eating out or relying on packaged foods that may contain your trigger foods.

Researching restaurant menus

It is crucial to research restaurant menus before dining out to find safe options if you have food sensitivities. Many restaurants now provide allergen menus or can prepare meals according to specific dietary needs. It is also important to communicate your food sensitivities to your server or restaurant staff, so they can take the necessary precautions when preparing your meal.

Finding alternative foods

It is important to find substitute foods that are safe for consumption to maintain a healthy diet while avoiding trigger foods. Trying new recipes, experimenting with new foods, and finding alternatives for your favorite trigger foods can be helpful. There are various options available, including non-dairy milk, gluten-free bread, and nut-free snacks.

To sum up, preventing food sensitivities necessitates being diligent and paying close attention to the foods you consume. By examining food labels, cooking meals at home, investigating restaurant menus, and locating alternative foods, you can effectively handle your food sensitivities and adhere to a nutritious diet.

Importance Of A Balanced Diet In Patients With Food Sensitivities

Maintaining a balanced diet is essential for overall health and well-being, especially for those who have food sensitivities. A balanced diet provides the necessary nutrients for the body to function properly and helps avoid triggers that can cause adverse reactions. Here are some reasons why a balanced diet is important for those with food sensitivities:

Ensuring adequate nutrient intake

Individuals with food sensitivities may face difficulties in obtaining all essential nutrients as their sensitivity may limit certain food groups. However, by maintaining a balanced diet that includes a variety of safe and nutritious foods, they can ensure adequate nutrient intake. For instance, if someone is unable to consume dairy products due to lactose intolerance, they can substitute it with other calcium sources like leafy greens, fortified non-dairy milk, and fish.

Incorporating a variety of foods

Incorporating a variety of foods

A diverse diet is crucial to prevent nutrient deficiencies and enhance overall health. For individuals with food sensitivities, it can be tempting to entirely eliminate certain food groups, which can result in a limited diet lacking essential nutrients. However, including a variety of safe and nutritious foods in their diet can help maintain a balanced and healthy diet.

Working with a nutritionist

A registered dietitian or nutritionist can offer valuable support to individuals with food sensitivities in creating a well-balanced meal plan that incorporates a wide range of safe and nutritious foods. They can also assist in identifying trigger foods and providing guidance on avoiding them while still ensuring adequate nutrient intake. Additionally, a nutritionist can educate individuals on reading food labels, cooking techniques, and healthy substitutions to maintain a balanced and wholesome diet.

To summarize, A balanced diet is essential for people with food sensitivities to maintain their health and avoid trigger foods. It involves ensuring sufficient nutrient intake, including a variety of nutritious foods, and seeking the guidance of a nutritionist. By following the above-mentioned guidelines, individuals with food sensitivities can achieve a balanced diet that supports their well-being and quality of life.


In conclusion, various foods can trigger food sensitivities, including gluten-containing grains, dairy products, soy products, nuts and seeds, shellfish, nightshade vegetables, and eggs. These foods can cause a range of symptoms from mild to severe, such as digestive problems, hives, and anaphylaxis. 

If you suspect that you have food sensitivity, it is recommended to consult a doctor or registered dietitian for professional guidance. They can help identify trigger foods, provide advice on label reading, and create a safe and balanced meal plan.

It's essential to maintain a healthy, balanced diet while avoiding trigger foods to ensure that you are receiving all the necessary nutrients. By incorporating a variety of safe and nutritious foods, you can meet your nutritional needs while managing food sensitivities. Working with a professional can provide education on healthy substitutions and cooking tips to help you maintain a healthy and fulfilling lifestyle.
