Macro partitioning
Using the 10:1 ratio of total carbohydrate to fiber to identify whole grain products selects foods with significantly higher fiber, lower sugars, lower sodium, and lower likelihood of trans-fats compared to other common identification criteria like the Whole Grain Stamp or 'whole' listed as the first ingredient.
To choose healthier whole grain products, look for items where the ratio of total carbohydrates to fiber is 10:1 or lower. This simple metric identifies products with more fiber, less sugar, less sodium, and fewer trans-fats than those identified by common labels like the Whole Grain Stamp or simply listing 'whole grain' first. Always check the nutrition facts panel to confirm.
Among proposed WG criteria, the 10:1-ratio identified the most healthful WG products. ... Products achieving the 10:1-ratio also contained lower sugar (21?28 g/serving, P 5 0?01), sodium (215?4 mg/serving, P 5 0?04) and likelihood of trans-fats (OR 5 0?14, P , 0?0001), without energy differences.
Why this rating
Large observational study (n=545) with rigorous statistical analysis, but limited to two grocery chains and specific product categories.
