Food allergies and intolerances in young people have become increasingly prevalent in recent years. According to Food Standards UK, between 5% – 8% of children have a food allergy, and food allergies are on the rise. Similarly, food intolerances are also common in young people and can cause a variety of symptoms, ranging from mild to severe. As a result, it is crucial to understand and manage food allergies and intolerances in young people to ensure their safety and wellbeing.
In this blog post, we will discuss the definitions, types, symptoms, diagnosis, and treatment of food allergies and intolerances in young people. Additionally, we will explore the prevalence of food allergies and intolerances in young people. Finally, we will offer tips for managing them in school and social situations. By understanding and effectively managing food allergies and intolerances in young people, we can ensure that they are able to lead healthy and happy lives. However, let’s start by having a quick look at the differences between food allergies and food intolerances.
Main Differences
Food allergies and food intolerances are both related to the way the body reacts to certain foods. However, there are some key differences between the two.
- Immune system involvement: Food allergies involve an immune system response to a particular food, while food intolerances do not. In food allergies, the immune system mistakenly identifies a specific food as harmful and triggers an allergic reaction, which can be life-threatening in some cases. In contrast, food intolerances involve an inability to digest or process certain foods and do not involve the immune system.
- Severity of symptoms: The symptoms of food allergies tend to be more severe and can include hives, swelling, difficulty breathing, and even anaphylaxis, a life-threatening reaction that can occur rapidly. In contrast, food intolerances tend to cause milder symptoms such as bloating, gas, diarrhoea, and nausea.
- Timing of onset: The timing of symptoms can also differ between food allergies and intolerances. Food allergies often cause immediate symptoms, sometimes within seconds or minutes after exposure to the allergen, while food intolerances may take longer to appear, sometimes hours or even days after consuming the offending food.
- Treatment: The treatment for food allergies and intolerances also differs. Food allergies require strict avoidance of the allergen and may involve carrying an epinephrine auto-injector to treat severe allergic reactions. In contrast, food intolerances may be managed through dietary changes, enzyme supplements, or other medications.
Overall, while food allergies and intolerances share some similarities in terms of symptoms and dietary restrictions, the underlying mechanisms and severity of symptoms differ significantly. It is important to understand the differences between these conditions to properly manage and treat them. Now, let’s look at food allergies and food intolerances in more detail.
Understanding Food Allergies
Understanding food allergies is crucial in ensuring that individuals who suffer from them receive proper care and management. In this section, we will discuss what food allergies are, the different types of food allergies, the symptoms associated with them, common allergens, and how they are diagnosed and treated.
A. Definition
A food allergy is an abnormal immune response to a particular food that the body mistakenly identifies as harmful. The immune system responds by producing an antibody called immunoglobulin E (IgE), which triggers the release of histamine and other chemicals, causing an allergic reaction. Food allergies can range from mild to severe and can cause symptoms ranging from hives and rashes to anaphylaxis, a life-threatening reaction.
B. Types
There are several types of food allergies, including:
- IgE-mediated allergies – This is the most common type of food allergy and occurs when the immune system produces IgE antibodies in response to a specific food. Symptoms may appear within minutes to an hour after consuming the allergen.
- Non-IgE-mediated allergies – This type of food allergy does not involve IgE antibodies but instead activates other parts of the immune system, causing delayed allergic reactions that can occur several hours or even days after exposure to the allergen.
- Exercise-induced food allergies – This type of food allergy is triggered by exercise, which can cause symptoms such as itching, hives, and difficulty breathing.
C. Symptoms of Food Allergies
The symptoms of a food allergy can vary depending on the severity of the reaction and the individual’s sensitivity to the allergen. Common symptoms include:
- Hives, itching, or rash
- Swelling of the lips, tongue, or throat
- Abdominal pain, diarrhoea, or vomiting
- Difficulty breathing, wheezing, or coughing
- Anaphylaxis, a severe and potentially life-threatening reaction that can cause a drop in blood pressure, loss of consciousness, and respiratory distress.
D. Common Food Allergens
While any food can cause an allergic reaction, there are some foods that are more likely to cause allergies than others. The most common food allergens include:
- Milk
- Eggs
- Peanuts
- Tree nuts (such as walnuts, almonds, and cashews)
- Fish
- Shellfish
- Soy
- Wheat
E. Diagnosis and Treatment
Food allergies can be diagnosed through a combination of medical history, physical examination, and allergy testing. Treatment for food allergies includes avoiding the allergen and carrying an epinephrine auto-injector in case of a severe reaction. In some cases, medication may also be prescribed to alleviate symptoms. In addition to medical treatment, it is essential to educate individuals with food allergies and their families on how to manage their condition, including how to read food labels, avoid cross-contamination, and respond to an allergic reaction.
Summary
Food allergies can cause a wide range of symptoms and can be potentially life-threatening. Understanding the different types of food allergies, their symptoms, common allergens, and how they are diagnosed and treated is essential in ensuring proper management and care.
Understanding Food Intolerances
Food intolerances are a common digestive issue that affects many people. In this section, we will discuss what food intolerances are, the different types of food intolerances, the symptoms associated with them, common intolerances, and how they are diagnosed and treated.
A. Definition
Food intolerances are a digestive disorder that occurs when the body is unable to properly digest or absorb certain foods. Unlike food allergies, food intolerances do not involve the immune system and are typically not life-threatening. Symptoms of food intolerances can range from mild to severe and can affect various parts of the body, including the digestive system, skin, and respiratory system.
B. Types
There are several types of food intolerances, including:
- Lactose intolerance – This is the most common type of food intolerance and occurs when the body is unable to digest lactose, a sugar found in milk and dairy products.
- Gluten intolerance – Gluten is a protein found in wheat, barley, and rye. Some people are unable to properly digest gluten, leading to a condition known as gluten intolerance or non-celiac gluten sensitivity.
- Fructose intolerance – Fructose is a sugar found in fruits, honey, and high-fructose corn syrup. Some people are unable to properly absorb fructose, leading to symptoms such as bloating, gas, and diarrhoea.
- Histamine intolerance – Histamine is a compound found in many foods, including aged cheese, fermented foods, and alcohol. Some people are unable to properly break down histamine, leading to symptoms such as headaches, hives, and digestive issues.
C. Symptoms of Food Intolerances
The symptoms of food intolerances can vary depending on the type of intolerance and the individual’s sensitivity to the offending food. Common symptoms include:
- Abdominal pain, bloating, and gas
- Diarrhoea or constipation
- Skin rashes, hives, or eczema
- Headaches or migraines
- Fatigue and weakness
- Respiratory problems, such as asthma or congestion
D. Common Food Intolerances
While any food can cause an intolerance, there are some foods that are more likely to cause issues. The most common food intolerances include:
- Dairy products
- Wheat and gluten-containing foods
- Soy products
- Certain fruits and vegetables, such as onions, garlic, and broccoli
- Processed foods containing high levels of sugar or artificial sweeteners.
E. Diagnosis and Treatment of Food Intolerances
Food intolerances can be diagnosed through a combination of medical history, physical examination, and elimination diets. Treatment for food intolerances typically involves avoiding the offending food and managing symptoms through dietary changes and medication. For example, lactose intolerant individuals may need to avoid dairy products or take lactase supplements to aid in digestion. It is essential to work with a healthcare provider to properly diagnose and manage food intolerances.
Summary
Food intolerances can cause a wide range of symptoms and can significantly impact an individual’s quality of life. Understanding the different types of food intolerances, their symptoms, common intolerances, and how they are diagnosed and treated is essential in ensuring proper management and care.
