What Are Food Additives?
Think of food additives as the support crew for your packaged foods. They are substances intentionally added to products for a specific technical purpose. This can include preserving freshness, improving texture, enhancing flavour, or adding colour. Additives
can be derived from natural sources like plants or minerals, or they can be synthetic. In India, the Food Safety and Standards Authority of India (FSSAI) regulates which additives are permitted and in what quantities. Common examples include preservatives like sodium benzoate, sweeteners like aspartame, and flavour enhancers like Monosodium Glutamate (MSG). They are not ingredients you would typically eat on their own but are functional components in processed foods.
What Are Food Allergens?
A food allergen, on the other hand, is a specific, naturally occurring protein within a food that the body of a susceptible person mistakenly identifies as a threat. For most people, these proteins are completely harmless. Common food allergens in India include milk, eggs, peanuts, tree nuts, wheat, soy, fish, and shellfish. Other regional allergens like chickpeas and lentils are also prevalent. Unlike additives which are added for function, allergens are integral parts of the food itself, like the protein in a peanut or in cow's milk.
The Body's Reaction: Immune Attack vs. Chemical Sensitivity
The fundamental difference between an allergy and an additive reaction lies in how your body responds. A food allergy is an immune system response. When an allergic person consumes an allergen, their immune system overreacts by producing antibodies called Immunoglobulin E (IgE). This triggers a cascade of chemicals, like histamine, that can cause symptoms ranging from mild hives and swelling to severe, life-threatening anaphylaxis. Even a tiny amount of the allergen can set off this reaction. Conversely, a reaction to a food additive is typically a food intolerance or sensitivity, not a true allergy. It does not involve the immune system in the same way. Symptoms are often related to the digestive system—like bloating, gas, or headaches—and are usually less severe. The reaction is often dose-dependent, meaning you might only feel ill after consuming a significant amount of the additive.
How to Spot Them on Indian Food Labels
Navigating ingredient lists becomes much simpler once you know what to look for. FSSAI has specific labelling rules to help consumers. Allergens: FSSAI mandates that the eight most common allergens must be clearly declared. You will often find them printed in bold within the ingredients list or in a separate 'Contains:' statement for easy visibility. This helps people with allergies quickly identify potential risks. Additives: Food additives must also be listed. They are typically identified by their functional class (e.g., 'Preservative', 'Acidity Regulator') followed by their specific name or their International Numbering System (INS) number, such as 'Preservative (INS 211)' for sodium benzoate. This transparency allows you to identify specific additives you may be sensitive to.
