1. The Hidden Gluten in Sauces and Condiments

Sauces and condiments are often overlooked in the quest for a gluten-free diet. Yet, they can be a major source of hidden gluten. Many sauces use wheat flour as a thickening agent or contain soy sauce, which is traditionally made with wheat. Salad dressings, marinades, and gravies are common culprits. For those seeking to avoid gluten, it's essential to read labels meticulously or opt for brands that specifically label their products as gluten-free. Making homemade versions can also be a safe and satisfying alternative, allowing control over every ingredient.

2. The Deceptive Allure of Processed Meats

Processed meats, such as sausages, hot dogs, and deli meats, may seem like safe gluten-free options. However, many of these products contain fillers, binders, and flavorings that include gluten. Even meats labeled as "natural" or "organic" are not immune to this issue. Cross-contamination during processing is another risk, as shared equipment can introduce gluten into otherwise gluten-free products. To avoid these hidden pitfalls, it's crucial to choose meats labeled as gluten-free or to purchase fresh, unprocessed cuts and season them at home.
