Hidden Gluten: How to Spot It and Stay Safe in Everyday Foods

Gluten, a protein found in wheat, barley, rye, and their derivatives, can cause reactions like stomach pain and inflammation in sensitive individuals. While exact global figures for diagnosed gluten intolerance or coeliac disease remain unclear, market reports suggest 20-30% of the US population avoids gluten—though this includes undiagnosed cases and personal preferences rather than confirmed medical conditions.

Many common foods contain gluten, often as a stabiliser or thickener. Sliced bread, pasta, cereals, cookies, and breaded or battered foods are typical sources. Canned soups, salad dressings, broths, and traditional soy sauce also frequently include it. Even some ice creams, candies, and snacks may have small amounts, making them hard to spot without careful label checks.

Certain terms on packaging indicate gluten presence. Words like 'flour', 'malt', 'malt extract', 'modified wheat', 'modified starch', 'semolina', 'triticale', 'spelt', or 'kamut' all signal its inclusion. Oats, though naturally gluten-free, can become cross-contaminated during processing and should only be eaten if labelled 'gluten-free'. For those avoiding gluten, alternatives exist. Sourdough products and pseudocereals such as amaranth and quinoa provide safe options. Maintaining a balanced diet involves reading labels thoroughly, choosing certified products, and consulting a healthcare professional when needed.

Avoiding gluten requires vigilance, as it appears in many everyday foods and hidden ingredients. By identifying key terms on labels and opting for certified alternatives, individuals can manage their diet effectively. Professional guidance remains essential for those with diagnosed conditions to ensure nutritional needs are met.
