Is Kellog's Nutrigrain Blueberry Gluten Free?
No, Kellogg's Nutrigrain Blueberry bars are not gluten-free. While oats are naturally gluten-free, this specific bar is made with enriched wheat flour and wheat gluten. It also contains milk ingredients, making it unsuitable for those with celiac disease or lactose intolerance.
The Ingredient Breakdown
As a food scientist, I look past the marketing claims and straight at the formulation. When we analyze the crust of the Kellogg's Nutrigrain Blueberry bar, the verdict is immediate. The second ingredient listed is enriched flour, which is explicitly defined as wheat flour. This is the primary structural component of the bar and is a direct source of gluten.
Furthermore, the ingredient list includes wheat gluten further down. Manufacturers often add isolated wheat gluten to baked goods to improve texture and elasticity, ensuring the bar holds together. Even if the oats were pure (which is a separate issue), the addition of these two ingredients disqualifies the product from being gluten-free. Additionally, the crust contains whey, a milk derivative, which is a flag for those avoiding dairy.
It is also important to note the source of the oats. While oats themselves do not contain gluten, they are frequently processed in facilities that also handle wheat. Because this bar already contains wheat, cross-contamination is a guarantee rather than a risk. For anyone with Celiac disease, the presence of wheat flour alone is an absolute dealbreaker.
Nutritional Value
From a nutritional standpoint, the Kellogg's Nutrigrain Blueberry bar is designed as a convenience food. A standard bar contains approximately 130 to 140 calories, with a significant portion coming from carbohydrates. The sugar content is notable, hovering around 12 to 13 grams per bar, derived from sources like corn syrup, sugar, and dextrose.
While the bar does provide 100% of the daily value of several vitamins and minerals (such as Vitamin C and Iron), this is largely due to fortification rather than the natural density of the ingredients. The fat content is relatively low, usually around 2.5 grams, mostly from soybean oil. If you are monitoring your sugar intake or following a low-carb diet, this bar may not fit your limits, as the sugar-to-fiber ratio is not optimal for sustained energy.
