Nature Valley bars

Among records with exact values, Nature Valley Oats & Honey (21g) has the lowest recorded calories per bar (98 kcal), while Nature Valley Peanut & Chocolate (40g) has the highest recorded protein per bar (10.2g).

This selection includes the matching published records in the Which Bar catalogue, not an exhaustive market survey. Missing, qualified and disputed values are excluded from the ranges above. Ingredient, allergen and dietary evidence is available on each product page. These are label comparisons, not hands-on taste or fullness rankings. Recipes and pack prices can change; check the seller and current wrapper.
