The Ingredient Breakdown
When analyzing whether a product is safe for a gluten-free diet, we look strictly at the ingredient deck. For StarKist Chunk Light Tuna in Water, the label is refreshingly simple and poses zero risk for gluten exposure.
The primary ingredient is, of course, Light Tuna. This is a pure protein source and is naturally free of gluten. The second ingredient is Water, used for canning, which is also completely safe. Unlike many processed foods that rely on thickeners, hydrolyzed vegetable protein (often derived from wheat), or yeast extracts to create texture and flavor, this product relies on the natural integrity of the fish.
It is also important to note the absence of "natural flavors" or "spices" without specification. While these terms can sometimes hide gluten in highly processed snacks, in the context of canned tuna, they are rarely a concern.
