The most prevalent food allergies include peanuts, dairy, shellfish, gluten, eggs, and tree nuts. These allergies can cause a wide range of lesser and severe symptoms, such as hives, swelling, difficulty breathing, and even life-threatening reactions.

It's important to be aware of these common food allergens and their potential effects so that you can make informed decisions about the food you make on your mobile catering van and avoid any potential risks. Let's explore these major food allergies further to gain a better understanding of the most common food allergies.

Key takeaways

  • Peanut allergies affect approximately 1 in 50 children and 1 in 200 adults and the prevalence has been increasing in recent years.
  • Dairy allergies are a reaction to cow's milk proteins and can cause food allergy symptoms such as hives, wheezing, vomiting, and anaphylaxis.
  • Shellfish allergies are more common in adults and can range from mild to life-threatening symptoms.
  • Gluten intolerance is different from coeliac disease and can cause symptoms such as abdominal pain, bloating, and fatigue.

Peanuts

If someone is allergic to peanuts, they are not alone as it is one of the most common food allergies affecting approximately 1 in 50 children and 1 in 200 adults. Peanut allergy prevalence has been on the rise in recent years, making it a significant concern for many individuals. Fortunately, there are various peanut allergy treatments available to manage this condition.

The first step in managing a peanut allergy is to avoid any contact with peanuts or peanut products. This means carefully reading food labels and being cautious when selling food from your catering van.

Dairy

When it comes to food allergies, another common one to be aware of is dairy. Dairy allergy is a reaction to the proteins found in cow's milk, and it can cause a range of symptoms, including hives, wheezing, vomiting, and even anaphylaxis in severe cases.

If you suspect your customer has a dairy allergy, it is important to get them to consult with a healthcare professional for a proper diagnosis. They may recommend an elimination diet or perform a skin prick test or blood test to confirm the food allergy diagnosis.

For those with a dairy allergy, it is essential to find suitable dairy-free substitutes to ensure a balanced diet. Fortunately, there are now many options available to buy nowadays.

Plant-based milk alternatives such as almond milk, soy milk, and oat milk are popular choices. These alternatives can be used in cooking, baking, and as a replacement for dairy milk in beverages. Other dairy-free substitutes include coconut milk, cashew cheese, and tofu-based products.

It is important to note that a dairy allergy is different from lactose intolerance. Lactose intolerance is the inability to digest lactose, the sugar found in milk, and dairy products.

The symptoms of lactose intolerance include bloating, gas, and diarrhoea. If you suspect someone may have lactose intolerance, it is also recommended for them to seek medical advice for a proper diagnosis.

Shellfish and crustaceans

Shellfish and crustacean allergies can cause severe reactions in some individuals. If someone has a crustacean or shellfish allergy, it is important to avoid consuming any type of shellfish, including shrimp, lobster, crab, and mussels. Shellfish or crustacean allergies are more common in adults than in children, and the symptoms can range from mild to life-threatening.

Symptoms of a shellfish or crustacean allergy can include itching, hives, swelling of the lips, tongue, or throat, difficulty breathing, nausea, vomiting, and in severe cases, anaphylaxis. Anaphylaxis is a serious allergic reaction that can cause a drop in blood pressure, loss of consciousness, and even death. If they experience any of these symptoms after consuming shellfish, ensure that they seek immediate medical attention.

Avoiding shellfish or crustaceans can be challenging, especially since it is a common ingredient in many dishes. However, there are plenty of shellfish-free recipes available that can still provide delicious and nutritious meals. Some alternatives to shellfish include fish, poultry, beef, pork, and vegetarian or vegan options such as tofu or tempeh.

When preparing meals for your mobile catering van, be mindful of cross-contamination. Ensure that utensils, cutting boards, and cookware used for shellfish are thoroughly cleaned before using them for other ingredients.

It is also important to read food labels carefully, as shellfish can sometimes be found in unexpected places, such as sauces or dressings. By being vigilant and informed, you can still enjoy creating a varied and satisfying meal without the risk of shellfish and crustacean allergies.

Gluten

Gluten is a protein found in wheat, barley, and rye that can cause adverse reactions in some individuals. If they have a gluten intolerance, consuming gluten can lead to symptoms such as abdominal pain, bloating, diarrhoea, and fatigue.

However, there are plenty of gluten-free alternatives packaged foods available that can help you manage your products and avoid these symptoms.

Gluten-free alternatives available

If someone has a gluten or wheat allergy, there are plenty of alternatives available for you to enjoy without sacrificing taste or texture. When it comes to gluten-free baking, there are a variety of flours that can be used as substitutes for traditional wheat flour.

These include almond flour, coconut flour, and rice flour, among others. These alternative flours can be used to make a wide range of baked goods, from breads and muffins to cakes and cookies.

Perhaps you could become one of the many gluten-free mobile catering vans that cater specifically to those with gluten allergies. These food trucks offer a variety of delicious options, from gluten-free pizzas and pastas to burgers and sandwiches with gluten-free buns.

Symptoms of gluten intolerance

Many individuals with gluten intolerance experience a range of symptoms. Gluten intolerance, also known as gluten sensitivity, is a condition where the body cannot properly digest gluten, a protein found in wheat, barley, and rye. When gluten is consumed, it triggers an immune response that can lead to various symptoms.

Common symptoms of gluten intolerance include digestive issues such as bloating, diarrhoea, constipation, and abdominal pain. Some individuals may also experience fatigue, joint pain, headaches, and skin rashes.

It is important to note that gluten intolerance is different from coeliac disease, which is an autoimmune disorder. While coeliac disease requires strict avoidance of gluten, individuals with gluten intolerance may have varying degrees of sensitivity. Gluten sensitivity testing can help diagnose the condition and determine the level of gluten avoidance necessary.

Furthermore, cross-contamination risks should be considered when following a gluten-free diet. Even small amounts of gluten can trigger symptoms in individuals with gluten intolerance. Therefore, it is crucial to read food labels carefully, avoid shared cooking utensils, utilise colour coded cleaning and cook with gluten-free options or dedicated gluten-free kitchens.

Eggs

Someone may be allergic to eggs. Egg allergies are one of the most common food allergies, particularly in children. If someone has an egg allergy, their immune system reacts to proteins found in eggs, causing symptoms that can range from mild to severe.

Egg allergy symptoms can occur shortly after consuming eggs or even just by being in close proximity to them. Common, allergic symptoms can include hives, skin rashes, itching, swelling, digestive problems, and respiratory issues such as wheezing or difficulty breathing. In severe cases, egg allergies can lead to anaphylaxis, a life-threatening allergic reaction that requires immediate medical attention.

If they have an egg allergy, it is important to avoid eggs and any food that contains eggs as an ingredient. Fortunately, there are egg substitutes available that can be used in certain foods, cooking and baking. These substitutes are often made from ingredients such as applesauce, mashed bananas, yoghurt, or commercial egg replacers.

If you suspect someone to have an egg allergy, it is crucial to get them to consult with a healthcare professional for proper diagnosis and guidance to treat symptoms. They can perform tests, such as skin prick tests or blood tests, to confirm the allergy and provide them with appropriate advice on managing their condition.

Tree nuts

As we move on from discussing eggs, it is important to be aware of another common food allergy: tree nuts. Tree nut allergies are one of the most prevalent food allergies, affecting millions of people worldwide. Tree nuts include almonds, walnuts, cashews, pistachios, and many more.

People with tree nut allergies experience an allergic reaction when they consume or come into contact with tree nuts, which can range from mild symptoms like rashes and itching to severe reactions such as difficulty breathing and anaphylaxis.

Living with a tree nut allergy can be challenging, especially when it comes to finding safe and nut-free recipes. However, it is essential to prioritise their safety and avoid any potential triggers.

Many recipes can be easily modified to be nut-free by substituting tree nuts with seeds or other ingredients. You can also find a variety of nut-free recipes online or in cookbooks specifically designed for individuals with food allergies.

When preparing meals, it is important to read food labels carefully, as tree nuts can be found in unexpected places. Food manufacturers are required to list the presence of major allergens, including tree nuts, on their labels.

However, cross-contamination is also a concern, so it is crucial to look for products with clear "Nut-free" labels or those certified by organisations that guarantee allergen-free production.
