Maybe it was peanuts, shellfish, or even milk. These may be the signs that your body is warning you about having a food allergy.<\/p>\n\n\n\nFood allergies occur when your immune system mistakenly detects harmless foods as a threat and reacts against them1<\/a><\/sup>. Most food allergies happen because of a substance in your body called IgE (an antibody). However, some allergies happen in different ways or through a mix of reactions, sometimes involving other parts of the immune system, called T cells2<\/a><\/sup>.<\/p>\n\n\n\nWhile some reactions are mild, there may be certain conditions which might turn dangerous or severe1<\/a><\/sup>. This is why recognising or identifying a food allergy is very important.<\/p>\n\n\n\nThis blog will help you understand what exactly food allergies are, how to recognise them, what are their types, common foods that can cause allergies and when to seek medical attention.<\/p>\n\n\n\n<\/span>What Is a Food Allergy?<\/strong><\/span><\/h2>\n\n\n\nAs mentioned earlier, food allergy is a condition that occurs when your immune system mistakenly detects harmless food you eat as a threat. While your immune system normally protects you from harmful substances, here some food items you consume are flagged as harmful by the body, leading to allergic reactions. This condition usually causes only mild reactions. But in some cases, it may become dangerous or life-threatening, causing severe reactions (anaphylaxis)1<\/a><\/sup>.<\/p>\n\n\n\nPeople often get confused between food allergies and food intolerances. These are different in the following ways:<\/p>\n\n\n\nFeature<\/strong>\u00a0<\/td>Food Allergy<\/strong>\u00a0<\/td>Food Intolerance<\/strong>\u00a0<\/td><\/tr>Reactivity\u00a0<\/td>The immune system is involved1<\/a><\/sup><\/td>Usually related to difficulty digesting food\u00a0(immune\u00a0system has no role)1<\/a><\/sup><\/td><\/tr>Trigger\u00a0<\/td>Can occur with\u00a0very small\u00a0amount\u00a0of food3<\/a><\/sup>\u00a0<\/td>Based on portions\u00a0different people\u00a0have\u00a0different thresholds (portion\u00a0size matters)<\/td><\/tr>Severity\u00a0<\/td>Might cause severe allergic reation1<\/a><\/sup><\/td>Typically\u00a0digestive symptoms like bloating or gas trouble1<\/a><\/sup><\/td><\/tr>Occurrence of symptoms\u00a0<\/td>Can\u00a0start as soon as after eating the allergic food to within 2 hours1<\/a><\/sup><\/td>May cause immediate symptoms, or take 1-2 days4<\/a><\/sup>\u00a0<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nNow you might be clear with the food allergy meaning. Even if you think you cannot distinguish whether you have an allergy or intolerance, do not wait for the symptoms to get worse, immediately consult your doctor<\/a> for confirmation, as unattended allergies can be life-threatening.<\/p>\n\n\n\n<\/span>Food Allergy Symptoms<\/strong><\/span><\/h2>\n\n\n\nFood allergies bring about several symptoms. These food allergy symptoms can be classified as follows:<\/p>\n\n\n\n1. Skin Symptoms<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nThese are the most common indications of food allergies3<\/a><\/sup>.<\/p>\n\n\n\n\nHives:<\/strong> Raised, itchy red rashes<\/li>\n\n\n\nItching: <\/strong>Itchiness inside the mouth, throat or ears<\/li>\n\n\n\nAngioedema: <\/strong>Swelling on face, around the eyes, lips, tongue, and inside mouth5<\/a><\/sup><\/li>\n\n\n\nFlushed skin: <\/strong>Redness on the skin1<\/a><\/sup><\/li>\n<\/ul>\n\n\n\n2. Digestive Symptoms<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nThese might occur alongside skin symptoms. Appear within half an hour of consuming food3<\/a><\/sup>.<\/p>\n\n\n\n\nAbdominal pain:<\/strong> Stomach cramps and belly pain<\/li>\n\n\n\nVomiting and nausea: <\/strong>Common reactions soon after ingestion<\/li>\n\n\n\nDiarrhoea: <\/strong>Loose motion1<\/a><\/sup><\/li>\n<\/ul>\n\n\n\n3. Respiratory Symptoms<\/strong><\/h3>\n\n\n\nImage Source: freepik.com<\/sub><\/figcaption><\/figure><\/div>\n\n\nThese are crucial as they can progress to life-threatening conditions.<\/p>\n\n\n\n\nWheezing:<\/strong> High-pitched noise or sound while breathing (exhalation)4<\/a><\/sup>, caused by narrowing of airways.<\/li>\n\n\n\nShortness of Breath:<\/strong> Difficulty in breathing1<\/a><\/sup><\/li>\n\n\n\nCough:<\/strong> Repetitive or persistent cough, sometimes combined with wheezing3<\/a>,4<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n4. Severe Symptoms<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nThese are much dangerous symptoms that should not be ignored, as they may be a sign of anaphylaxis, a rapid and severe allergic reaction affecting the whole body and can be fatal. Symptoms include:<\/p>\n\n\n\n\nNarrowing or swelling of airways restricting breathing3<\/a><\/sup><\/li>\n\n\n\nSwelling of the throat causing breathing difficulties<\/li>\n\n\n\nSudden and severe coming down of blood pressure (BP)<\/li>\n\n\n\nUnable to respond (loss of consciousness)1<\/a><\/sup><\/li>\n\n\n\nBody turning pale and feeling weak, loose, or not firm (particular symptom in children)4<\/a><\/sup><\/li>\n\n\n\nPersistent fainting, dizziness and weak pulse4<\/a>,6<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\nNote:<\/em><\/strong> Although some symptoms are classified into different categories (apart from being listed under the severe section), this does not mean they are less dangerous. Any allergic symptom can progress to severe reactions. Therefore, it is important to consult your doctor if you think the allergy symptoms or reactions are persisting for a while or are getting worse.<\/em><\/p><\/div>Show Full Article<\/button><\/div>\n\n\n\n<\/span>Types of Food Allergies<\/strong><\/span><\/h2>\n\n\n\nBased on the reaction timing, the food allergies can be classified into three categories. They are:<\/p>\n\n\n\n1. IgE Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which involve a wide range of signs and symptoms. This type of food allergy is one of the main causes of severe allergic reactions that may lead to a need to go to the emergency room (especially in children)2<\/a><\/sup>.<\/p>\n\n\n\n\nMechanism:<\/strong> The immune system wrongly reacts to a certain food and makes special antibodies called IgE. These antibodies get attached to certain types of cells in the body, called mast cells. The next time the same food is consumed, these antibodies trigger the cells to produce a chemical called histamine, which causes the allergic reaction2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> They can appear even with minute quantities and appear soon after consumption or within 2 hours. Include both mild and severe symptoms such as hives, swelling, diarrhoea, vomiting, abdominal pain, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to peat nuts, tree nuts, shellfish, eggs, etc. Can cause a particular condition called oral allergy syndrome (people allergic to pollen react to raw fruits and vegetables because their proteins are similar to pollen; cooked forms may be tolerated)2<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n2. Non-IgE-Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which do not involve IgE antibodies, but other parts of the immune system. Therefore, they are harder to diagnose because there are only a few easy, painless tests to confirm them.<\/p>\n\n\n\n\nMechanism:<\/strong> Since they do not involve IgE, they are said to cause allergic reactions by other components of the immune system. This causes delayed reaction, mainly in the digestive tract7<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> As it is delayed, they may take more time to bring on the symptoms, mostly 48-72 hours, rather than immediately. In acute (sudden) reactions like food protein-induced enterocolitis syndrome, symptoms usually start 1-4 hours after eating the trigger food. Include symptoms like upper stomach pain, feeling sick, vomiting, blood or mucus in the stool, etc.<\/li>\n\n\n\nExamples: <\/strong>Allergies related to cow milk, soy, rice, etc. can cause conditions like food protein-induced enterocolitis syndrome (FPIES), food protein-induced allergic proctocolitis (FPIAP), etc8<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n3. Mixed Food Allergies<\/strong><\/h3>\n\n\n\nThese allergies are caused when immune reactions or allergy contributions in some foods are mediated by IgE and some other parts of the immune system, making them mixed.<\/p>\n\n\n\n\nMechanism: <\/strong>These allergies cause inflammation backed by IgE antibodies as well as by other immune cells of the immune system, which may contribute to both sudden and delayed reactions8<\/a><\/sup>. Once the food is ingested, it connects to the IgE antibodies, which are already attached to mast cells that release histamine, causing inflammation and allergic reactions. At the same time, other cells of the immune system, such as T Cells, reacts to food, causing slow, delayed symptoms2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> Involve sudden and delayed ones such as vomiting, nausea, stomach discomfort, and redness, rashes, and irritation of the skin, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to milk, wheat, soy, etc. Can cause conditions such as eosinophilic esophagitis, eczema, eosinophilic gastroenteritis8<\/a>,9<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n<\/span>Common Foods That Cause Allergies<\/strong><\/span><\/h2>\n\n\n\nThe following is a list of foods that can cause allergies especially in sensitive individuals:<\/p>\n\n\n\n1. Nuts and Peanut<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nPeanuts are the most common and dangerous ones causing allergies. Even a small amount may trigger the immune system, causing severe, life-threatening reactions. Commonly consumed nuts that cause allergies include almonds, cashews, Brazel nuts, pistachios, walnuts, etc. may also cause allergic reactions. Symptoms include hives, redness, itching, breathing problems (asthma, wheezing, etc.), digestive symptoms and sometimes severe reactions like constriction of airways, BP fall10<\/a><\/sup>.<\/p>\n\n\n\n2. Cow\u2019s Milk<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nAllergy to cow\u2019s milk can be seen in one in fifty babies, while this is rare in adults11<\/a><\/sup>. Some people, who are allergic to cow milk might develop allergies if they consume milk of other animals like goat, sheep, or buffalo. However, this isn\u2019t same for all (reactions are more common with goat and sheep milk, while buffalo milk may or may not cause a reaction). Symptoms caused by this allergy can vary from mild to severe, which include hives, itching, redness, swelling of the face, stomach discomfort and serious or life-threatening symptoms like breathing difficulties, paleness, loss of consciousness, etc. Foods containing cow\u2019s milk that can cause allergy include cheese, chocolate, ghee, ice cream, butter, yoghurt, etc11<\/a><\/sup>.<\/p>\n\n\n\n3. Fish and Shellfish<\/strong><\/h3>\n\n\n\nImage Source: freepik.com<\/sub><\/figcaption><\/figure><\/div>\n\n\nAllergies to fishes and shellfish can be seen more in adults and adolescents than in kids. It is said that one in every hundred people may have this allergy12<\/a><\/sup>. Symptoms can range from mild to severe, such as hives, lip swelling, itchiness, runny nose, breathing problems, throat tightness, stomach pain, vomiting, dizziness, body turning pale, losing consciousness, etc. The fish causing allergies include salmon, mackerel, tuna, trout, snapper, etc. The shellfish causing allergies include crustaceans (prawns, crab, lobster) and molluscs (squid, cuttlefish, mussels)12<\/a><\/sup>.<\/p>\n\n\n\n4.

They are:<\/p>\n\n\n\n1. IgE Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which involve a wide range of signs and symptoms. This type of food allergy is one of the main causes of severe allergic reactions that may lead to a need to go to the emergency room (especially in children)2<\/a><\/sup>.<\/p>\n\n\n\n\nMechanism:<\/strong> The immune system wrongly reacts to a certain food and makes special antibodies called IgE. These antibodies get attached to certain types of cells in the body, called mast cells. The next time the same food is consumed, these antibodies trigger the cells to produce a chemical called histamine, which causes the allergic reaction2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> They can appear even with minute quantities and appear soon after consumption or within 2 hours. Include both mild and severe symptoms such as hives, swelling, diarrhoea, vomiting, abdominal pain, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to peat nuts, tree nuts, shellfish, eggs, etc. Can cause a particular condition called oral allergy syndrome (people allergic to pollen react to raw fruits and vegetables because their proteins are similar to pollen; cooked forms may be tolerated)2<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n2. Non-IgE-Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which do not involve IgE antibodies, but other parts of the immune system. Therefore, they are harder to diagnose because there are only a few easy, painless tests to confirm them.<\/p>\n\n\n\n\nMechanism:<\/strong> Since they do not involve IgE, they are said to cause allergic reactions by other components of the immune system. This causes delayed reaction, mainly in the digestive tract7<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> As it is delayed, they may take more time to bring on the symptoms, mostly 48-72 hours, rather than immediately. In acute (sudden) reactions like food protein-induced enterocolitis syndrome, symptoms usually start 1-4 hours after eating the trigger food. Include symptoms like upper stomach pain, feeling sick, vomiting, blood or mucus in the stool, etc.<\/li>\n\n\n\nExamples: <\/strong>Allergies related to cow milk, soy, rice, etc. can cause conditions like food protein-induced enterocolitis syndrome (FPIES), food protein-induced allergic proctocolitis (FPIAP), etc8<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n3. Mixed Food Allergies<\/strong><\/h3>\n\n\n\nThese allergies are caused when immune reactions or allergy contributions in some foods are mediated by IgE and some other parts of the immune system, making them mixed.<\/p>\n\n\n\n\nMechanism: <\/strong>These allergies cause inflammation backed by IgE antibodies as well as by other immune cells of the immune system, which may contribute to both sudden and delayed reactions8<\/a><\/sup>. Once the food is ingested, it connects to the IgE antibodies, which are already attached to mast cells that release histamine, causing inflammation and allergic reactions. At the same time, other cells of the immune system, such as T Cells, reacts to food, causing slow, delayed symptoms2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> Involve sudden and delayed ones such as vomiting, nausea, stomach discomfort, and redness, rashes, and irritation of the skin, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to milk, wheat, soy, etc. Can cause conditions such as eosinophilic esophagitis, eczema, eosinophilic gastroenteritis8<\/a>,9<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n<\/span>Common Foods That Cause Allergies<\/strong><\/span><\/h2>\n\n\n\nThe following is a list of foods that can cause allergies especially in sensitive individuals:<\/p>\n\n\n\n1. Nuts and Peanut<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nPeanuts are the most common and dangerous ones causing allergies. Even a small amount may trigger the immune system, causing severe, life-threatening reactions. Commonly consumed nuts that cause allergies include almonds, cashews, Brazel nuts, pistachios, walnuts, etc. may also cause allergic reactions.

Some people, who are allergic to cow milk might develop allergies if they consume milk of other animals like goat, sheep, or buffalo. However, this isn\u2019t same for all (reactions are more common with goat and sheep milk, while buffalo milk may or may not cause a reaction). Symptoms caused by this allergy can vary from mild to severe, which include hives, itching, redness, swelling of the face, stomach discomfort and serious or life-threatening symptoms like breathing difficulties, paleness, loss of consciousness, etc. Foods containing cow\u2019s milk that can cause allergy include cheese, chocolate, ghee, ice cream, butter, yoghurt, etc11<\/a><\/sup>.<\/p>\n\n\n\n3.

Symptoms can range from mild to severe, such as hives, lip swelling, itchiness, runny nose, breathing problems, throat tightness, stomach pain, vomiting, dizziness, body turning pale, losing consciousness, etc. The fish causing allergies include salmon, mackerel, tuna, trout, snapper, etc. The shellfish causing allergies include crustaceans (prawns, crab, lobster) and molluscs (squid, cuttlefish, mussels)12<\/a><\/sup>.<\/p>\n\n\n\n4.

As mentioned earlier, food allergy is a condition that occurs when your immune system mistakenly detects harmless food you eat as a threat. While your immune system normally protects you from harmful substances, here some food items you consume are flagged as harmful by the body, leading to allergic reactions. This condition usually causes only mild reactions. But in some cases, it may become dangerous or life-threatening, causing severe reactions (anaphylaxis)1<\/a><\/sup>.<\/p>\n\n\n\nPeople often get confused between food allergies and food intolerances.

Now you might be clear with the food allergy meaning. Even if you think you cannot distinguish whether you have an allergy or intolerance, do not wait for the symptoms to get worse, immediately consult your doctor<\/a> for confirmation, as unattended allergies can be life-threatening.<\/p>\n\n\n\n<\/span>Food Allergy Symptoms<\/strong><\/span><\/h2>\n\n\n\nFood allergies bring about several symptoms.

Any allergic symptom can progress to severe reactions. Therefore, it is important to consult your doctor if you think the allergy symptoms or reactions are persisting for a while or are getting worse.<\/em><\/p><\/div>Show Full Article<\/button><\/div>\n\n\n\n<\/span>Types of Food Allergies<\/strong><\/span><\/h2>\n\n\n\nBased on the reaction timing, the food allergies can be classified into three categories. They are:<\/p>\n\n\n\n1. IgE Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which involve a wide range of signs and symptoms. This type of food allergy is one of the main causes of severe allergic reactions that may lead to a need to go to the emergency room (especially in children)2<\/a><\/sup>.<\/p>\n\n\n\n\nMechanism:<\/strong> The immune system wrongly reacts to a certain food and makes special antibodies called IgE. These antibodies get attached to certain types of cells in the body, called mast cells. The next time the same food is consumed, these antibodies trigger the cells to produce a chemical called histamine, which causes the allergic reaction2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> They can appear even with minute quantities and appear soon after consumption or within 2 hours. Include both mild and severe symptoms such as hives, swelling, diarrhoea, vomiting, abdominal pain, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to peat nuts, tree nuts, shellfish, eggs, etc. Can cause a particular condition called oral allergy syndrome (people allergic to pollen react to raw fruits and vegetables because their proteins are similar to pollen; cooked forms may be tolerated)2<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n2. Non-IgE-Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which do not involve IgE antibodies, but other parts of the immune system. Therefore, they are harder to diagnose because there are only a few easy, painless tests to confirm them.<\/p>\n\n\n\n\nMechanism:<\/strong> Since they do not involve IgE, they are said to cause allergic reactions by other components of the immune system. This causes delayed reaction, mainly in the digestive tract7<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> As it is delayed, they may take more time to bring on the symptoms, mostly 48-72 hours, rather than immediately. In acute (sudden) reactions like food protein-induced enterocolitis syndrome, symptoms usually start 1-4 hours after eating the trigger food. Include symptoms like upper stomach pain, feeling sick, vomiting, blood or mucus in the stool, etc.<\/li>\n\n\n\nExamples: <\/strong>Allergies related to cow milk, soy, rice, etc. can cause conditions like food protein-induced enterocolitis syndrome (FPIES), food protein-induced allergic proctocolitis (FPIAP), etc8<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n3. Mixed Food Allergies<\/strong><\/h3>\n\n\n\nThese allergies are caused when immune reactions or allergy contributions in some foods are mediated by IgE and some other parts of the immune system, making them mixed.<\/p>\n\n\n\n\nMechanism: <\/strong>These allergies cause inflammation backed by IgE antibodies as well as by other immune cells of the immune system, which may contribute to both sudden and delayed reactions8<\/a><\/sup>. Once the food is ingested, it connects to the IgE antibodies, which are already attached to mast cells that release histamine, causing inflammation and allergic reactions. At the same time, other cells of the immune system, such as T Cells, reacts to food, causing slow, delayed symptoms2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> Involve sudden and delayed ones such as vomiting, nausea, stomach discomfort, and redness, rashes, and irritation of the skin, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to milk, wheat, soy, etc. Can cause conditions such as eosinophilic esophagitis, eczema, eosinophilic gastroenteritis8<\/a>,9<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n<\/span>Common Foods That Cause Allergies<\/strong><\/span><\/h2>\n\n\n\nThe following is a list of foods that can cause allergies especially in sensitive individuals:<\/p>\n\n\n\n1.

Therefore, it is important to consult your doctor if you think the allergy symptoms or reactions are persisting for a while or are getting worse.<\/em><\/p><\/div>Show Full Article<\/button><\/div>\n\n\n\n<\/span>Types of Food Allergies<\/strong><\/span><\/h2>\n\n\n\nBased on the reaction timing, the food allergies can be classified into three categories. They are:<\/p>\n\n\n\n1. IgE Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which involve a wide range of signs and symptoms. This type of food allergy is one of the main causes of severe allergic reactions that may lead to a need to go to the emergency room (especially in children)2<\/a><\/sup>.<\/p>\n\n\n\n\nMechanism:<\/strong> The immune system wrongly reacts to a certain food and makes special antibodies called IgE. These antibodies get attached to certain types of cells in the body, called mast cells. The next time the same food is consumed, these antibodies trigger the cells to produce a chemical called histamine, which causes the allergic reaction2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> They can appear even with minute quantities and appear soon after consumption or within 2 hours. Include both mild and severe symptoms such as hives, swelling, diarrhoea, vomiting, abdominal pain, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to peat nuts, tree nuts, shellfish, eggs, etc. Can cause a particular condition called oral allergy syndrome (people allergic to pollen react to raw fruits and vegetables because their proteins are similar to pollen; cooked forms may be tolerated)2<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n2. Non-IgE-Mediated Food Allergies<\/strong><\/h3>\n\n\n\nThese are types of food allergies which do not involve IgE antibodies, but other parts of the immune system. Therefore, they are harder to diagnose because there are only a few easy, painless tests to confirm them.<\/p>\n\n\n\n\nMechanism:<\/strong> Since they do not involve IgE, they are said to cause allergic reactions by other components of the immune system. This causes delayed reaction, mainly in the digestive tract7<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> As it is delayed, they may take more time to bring on the symptoms, mostly 48-72 hours, rather than immediately. In acute (sudden) reactions like food protein-induced enterocolitis syndrome, symptoms usually start 1-4 hours after eating the trigger food. Include symptoms like upper stomach pain, feeling sick, vomiting, blood or mucus in the stool, etc.<\/li>\n\n\n\nExamples: <\/strong>Allergies related to cow milk, soy, rice, etc. can cause conditions like food protein-induced enterocolitis syndrome (FPIES), food protein-induced allergic proctocolitis (FPIAP), etc8<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n3. Mixed Food Allergies<\/strong><\/h3>\n\n\n\nThese allergies are caused when immune reactions or allergy contributions in some foods are mediated by IgE and some other parts of the immune system, making them mixed.<\/p>\n\n\n\n\nMechanism: <\/strong>These allergies cause inflammation backed by IgE antibodies as well as by other immune cells of the immune system, which may contribute to both sudden and delayed reactions8<\/a><\/sup>. Once the food is ingested, it connects to the IgE antibodies, which are already attached to mast cells that release histamine, causing inflammation and allergic reactions. At the same time, other cells of the immune system, such as T Cells, reacts to food, causing slow, delayed symptoms2<\/a><\/sup>.<\/li>\n\n\n\nSymptoms:<\/strong> Involve sudden and delayed ones such as vomiting, nausea, stomach discomfort, and redness, rashes, and irritation of the skin, etc.<\/li>\n\n\n\nExamples:<\/strong> Allergies related to milk, wheat, soy, etc. Can cause conditions such as eosinophilic esophagitis, eczema, eosinophilic gastroenteritis8<\/a>,9<\/a><\/sup>.<\/li>\n<\/ul>\n\n\n\n<\/span>Common Foods That Cause Allergies<\/strong><\/span><\/h2>\n\n\n\nThe following is a list of foods that can cause allergies especially in sensitive individuals:<\/p>\n\n\n\n1. Nuts and Peanut<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nPeanuts are the most common and dangerous ones causing allergies. Even a small amount may trigger the immune system, causing severe, life-threatening reactions. Commonly consumed nuts that cause allergies include almonds, cashews, Brazel nuts, pistachios, walnuts, etc. may also cause allergic reactions. Symptoms include hives, redness, itching, breathing problems (asthma, wheezing, etc.), digestive symptoms and sometimes severe reactions like constriction of airways, BP fall10<\/a><\/sup>.<\/p>\n\n\n\n2. Cow\u2019s Milk<\/strong><\/h3>\n\n\n\n<\/figure><\/div>\n\n\nAllergy to cow\u2019s milk can be seen in one in fifty babies, while this is rare in adults11<\/a><\/sup>. Some people, who are allergic to cow milk might develop allergies if they consume milk of other animals like goat, sheep, or buffalo. However, this isn\u2019t same for all (reactions are more common with goat and sheep milk, while buffalo milk may or may not cause a reaction). Symptoms caused by this allergy can vary from mild to severe, which include hives, itching, redness, swelling of the face, stomach discomfort and serious or life-threatening symptoms like breathing difficulties, paleness, loss of consciousness, etc. Foods containing cow\u2019s milk that can cause allergy include cheese, chocolate, ghee, ice cream, butter, yoghurt, etc11<\/a><\/sup>.<\/p>\n\n\n\n3. Fish and Shellfish<\/strong><\/h3>\n\n\n\nImage Source: freepik.com<\/sub><\/figcaption><\/figure><\/div>\n\n\nAllergies to fishes and shellfish can be seen more in adults and adolescents than in kids. It is said that one in every hundred people may have this allergy12<\/a><\/sup>. Symptoms can range from mild to severe, such as hives, lip swelling, itchiness, runny nose, breathing problems, throat tightness, stomach pain, vomiting, dizziness, body turning pale, losing consciousness, etc. The fish causing allergies include salmon, mackerel, tuna, trout, snapper, etc. The shellfish causing allergies include crustaceans (prawns, crab, lobster) and molluscs (squid, cuttlefish, mussels)12<\/a><\/sup>.<\/p>\n\n\n\n4.
