Food allergies are on the rise in India, affecting both adults and children. Although national statistics may vary, there is an increasing prevalence of allergies to common foods like dairy, seafood, and nuts. This rise is influenced by environmental factors, dietary habits, early exposure to allergenic foods, and more. The risk is compounded by a lack of awareness and delayed recognition of symptoms, as many individuals only realize they have an allergy after experiencing a severe reaction.
Understanding these contributing factors and promoting allergy awareness are essential for managing and reducing the risks associated with food allergies in India. This blog will delve into the most common food allergies, their symptoms, and ways to be vigilant.
9 Most Common Food Allergies Today
Food allergies are increasingly prevalent worldwide, with eight key foods, known as “The Big Eight,” accounting for most cases. Here’s a closer look at these common allergens:
- Milk
Milk allergies, particularly common in children, are caused by an immune reaction to milk proteins like casein and whey. Symptoms can range from itching and vomiting to severe allergic reactions. While many outgrow milk allergies, some individuals continue to experience symptoms into adulthood. It’s important not to confuse milk allergy with lactose intolerance, which involves digestive issues rather than an immune response. - Eggs
Egg allergies are triggered by proteins in egg whites, such as ovalbumin, ovomucoid, and lysozyme. These proteins activate immune cells, causing histamine release and symptoms like rashes and breathing difficulties, especially in children. While cooking eggs can reduce allergenic proteins, it doesn’t eliminate the risk, so complete avoidance of both egg whites and yolks is necessary for those with egg allergies. - Peanuts
Peanut allergies are triggered by specific proteins like Ara h 2 and Ara h 8 and can cause severe reactions, including anaphylaxis, a life-threatening condition. Peanut allergies often persist for life, and strict avoidance of all peanut-containing products is crucial. Individuals with peanut allergies should always have emergency treatments, such as an epinephrine auto-injector (EpiPen), readily available. - Tree Nuts
Allergies to tree nuts, including almonds, walnuts, and cashews, are caused by nut-specific proteins such as amandin in almonds. These allergies can provoke serious immune reactions, with cashews and pistachios often causing severe symptoms even in small quantities. Like peanut allergies, tree nut allergies are usually lifelong, and avoiding all forms of tree nuts is essential. - Soy
Soy allergies are a reaction to proteins like glycinin and beta-conglycinin found in soybeans and many processed foods. While more common in children, symptoms can vary from mild to severe. Those with soy allergies should be vigilant about checking food labels, as soy is often present in everyday items like bread, snacks, soups, and processed meats. - Wheat
Wheat allergies are often triggered by gluten proteins, particularly gliadin and glutenin, which provoke an immune response that disrupts the gut lining and affects nutrient absorption. It’s crucial to differentiate between wheat allergies, celiac disease, and gluten sensitivity. Gluten-free alternatives are widely available to help manage wheat-related allergies. - Fish
Fish allergies are caused by proteins such as parvalbumin in species like tuna, salmon, and cod. Symptoms range from mild itching to severe, potentially life-threatening reactions. Unlike many childhood allergies, fish allergies often persist into adulthood. Avoiding all fish types and having access to emergency medication, like epinephrine, is crucial for those affected. - Shellfish
Shellfish allergies, caused by proteins such as tropomyosin in crustaceans (shrimp, crab) and mollusks (clams, mussels), are among the most severe and often life-threatening food allergies. It’s important to distinguish between fish and shellfish allergies, as they involve different biological entities despite both being classified as seafood.
Managing food allergies requires awareness and strict avoidance of allergens. Understanding the symptoms and triggers can help those affected take proactive steps to safeguard their health.
The Final Word
In conclusion, understanding common food allergies is crucial, as they can range from mild discomfort to severe, life-threatening reactions. If you suspect you have a food allergy, it’s essential to seek medical advice for accurate diagnosis and effective management. By being aware of common allergens and their potential impacts, you can make informed decisions to protect your health and maintain a balanced, safe diet.
