Biomarkers included

• Buckwheat: Buckwheat intolerance is a condition in which the body has difficulty digesting buckwheat, leading to digestive symptoms. Unlike a buckwheat allergy, which triggers an immune response and can cause severe reactions, intolerance is generally limited to gastrointestinal discomfort.
• Celery: Celery intolerance and allergy refer to different reactions some individuals may have to celery, a common ingredient in soups, salads, and snacks. A celery allergy is an immune system response to the proteins in celery, which can cause serious symptoms. In contrast, celery intolerance primarily affects the digestive system, leading to discomfort without involving the immune response.
• Mustard: Mustard intolerance is a condition that reflects difficulty in digesting mustard and mustard-based products. Unlike a mustard allergy, which triggers an immune system response and more severe symptoms, mustard intolerance primarily causes digestive discomfort and gastrointestinal symptoms after consumption.
• Banana: Banana intolerance refers to a non-allergic reaction to bananas, a widely consumed and nutritious fruit. Unlike banana allergies, which trigger an immune response to specific banana proteins, intolerance usually stems from difficulties digesting certain components of the fruit.
• Cucumber: Cucumber intolerance is a condition in which the body has difficulty digesting cucumber, often resulting in gastrointestinal discomfort. Unlike a cucumber allergy, which triggers an immune response and can cause more severe reactions, cucumber intolerance typically leads to digestive symptoms after consumption.
• Rice: Rice allergy is an uncommon food allergy in which the body’s immune system reacts to proteins found in rice. Although less common than many other food allergies, it can cause a range of symptoms in sensitive individuals. It can affect both children and adults and may be triggered by either white or brown rice.
• Sheep's milk: Sheep's milk intolerance is a condition in which the body has difficulty digesting sheep's milk, leading to gastrointestinal symptoms. This intolerance differs from a sheep's milk allergy, which involves an immune response and can cause more severe reactions. Individuals with sheep's milk intolerance usually experience digestive discomfort after consuming sheep's milk or related products.
• Hazelnut: Hazelnut allergy is a type of tree nut allergy that reflects an immune response to proteins found in hazelnuts. It is a common food allergy that can cause reactions ranging from mild symptoms to severe anaphylaxis. Both raw and cooked hazelnuts can trigger this allergic reaction.
• Pork: Pork intolerance is a digestive condition characterized by difficulty processing pork, which can lead to gastrointestinal discomfort. Unlike a pork allergy, which involves an immune response and more severe symptoms, pork intolerance primarily causes digestive issues after consuming pork.

Common symptoms include bloating, gas, and abdominal pain after consuming green peas.
• Cod: Fish commonly consumed and used in various culinary dishes. Cod allergies can provoke digestive symptoms and anaphylaxis.
• Cabbage: Cabbage intolerance refers to difficulty digesting cabbage, often resulting in gastrointestinal discomfort. Unlike a cabbage allergy, which triggers an immune reaction, this intolerance is related to digestion and typically causes symptoms after eating cabbage.
• Egg white: Egg white allergy is a common food allergy, particularly in children, caused by the immune system’s overreaction to proteins found in egg whites. Reactions can vary from mild symptoms to severe, including anaphylaxis. While many children outgrow this allergy, some may continue to experience it into adulthood.
• Carrot: Carrot allergy is an allergic reaction triggered by specific proteins in carrots. Though uncommon, it can affect individuals with sensitivities to certain plant-based foods. It is often linked to Oral Allergy Syndrome (OAS), particularly in people allergic to birch or mugwort pollen, due to cross-reactive proteins.
• Mussels: Mussels intolerance is a condition in which the body has difficulty digesting mussels, often resulting in gastrointestinal discomfort. It differs from a mussels allergy, which involves an immune system reaction and can cause more severe symptoms. Individuals with mussels intolerance typically experience digestive issues after consuming this type of shellfish.
• Corn: Corn intolerance is a digestive condition that reflects the body’s difficulty in processing corn. Unlike a corn allergy, which is an immune system response causing more immediate and severe reactions, corn intolerance primarily leads to gastrointestinal symptoms and discomfort.
• Almond: Almond allergy is a condition that reflects the immune system’s reaction to proteins found in almonds, a type of tree nut. It is one of the more common tree nut allergies and can cause symptoms ranging from mild irritation to severe, potentially life-threatening reactions.
• Tomato: Tomato allergy is an immune response triggered by proteins found in tomatoes. Although less common than other food allergies, it can cause a variety of symptoms, primarily affecting the skin but potentially involving other body systems as well.
• Amaranth: Amaranth intolerance is a condition that refers to a non-allergic adverse reaction to amaranth, a nutrient-rich, gluten-free pseudocereal packed with vitamins and minerals. Unlike an amaranth allergy, which triggers an immune response to specific proteins, amaranth intolerance usually stems from difficulty digesting certain components of the grain.
• Chicken: Chicken intolerance is a condition in which the body has difficulty digesting chicken, resulting in digestive discomfort. Unlike a chicken allergy, which triggers an immune response and can cause more immediate and severe reactions, chicken intolerance typically leads to gastrointestinal symptoms after consumption.
• Green beans: Green beans intolerance is a condition in which the body has difficulty digesting green beans, resulting in gastrointestinal discomfort. Unlike a green beans allergy, which triggers an immune response and can cause more severe reactions, intolerance typically leads to digestive symptoms that appear after consuming green beans.
• Apple: Apple allergy is an allergic reaction to proteins found in apples, often linked to Oral Allergy Syndrome (OAS). It commonly occurs in people allergic to birch pollen, as similar proteins in apples can trigger cross-reactivity. Symptoms can range from mild oral discomfort to more pronounced reactions, though severe cases are uncommon.
• Soy: Soy allergy is a common food allergy that occurs when the immune system reacts to proteins found in soy. It is especially prevalent in children and can cause symptoms ranging from mild to severe, including anaphylaxis. Soy is present in many foods and products, and while this allergy often appears in early childhood, some children may outgrow it over time.
• Kiwi: Kiwi intolerance is a digestive condition characterized by difficulty in processing kiwi fruit. Unlike a kiwi allergy, which triggers an immune system response and can cause severe and immediate reactions, kiwi intolerance mainly results in digestive discomfort and symptoms after eating the fruit.
• Oats: Oats intolerance is a condition characterized by difficulty digesting oats, causing gastrointestinal discomfort. Unlike an oats allergy, which triggers an immune system response and can lead to more severe symptoms, oats intolerance primarily results in digestive issues after consuming oats or oat-based products.
• Egg yolk: Yolk intolerance is a condition that reflects difficulty in digesting egg yolks. Unlike an egg allergy, which triggers an immune system response and can cause severe reactions, yolk intolerance primarily leads to digestive discomfort.
