A loaf of brown-colored bread labeled "Multigrain", "7-Grain", "12-Grain" or "Made with Whole Wheat" looks like a whole-grain staple at first glance.
Yet in food labeling, "multigrain" only means that more than one type of grain is present in the recipe—it says nothing about whether those grains are whole or refined.
What "Multigrain" and "Whole Grain" actually mean
As Harvard T.H. Chan School of Public Health's Nutrition Source explains, a true whole grain contains all three original parts of the kernel—the fiber-rich bran, the nutrient-packed germ and the starchy endosperm—in their natural proportions. Intact whole grains include whole wheat, brown rice, rolled or steel-cut oats, barley (hulled), quinoa, millet, buckwheat, amaranth, teff, sorghum, rye and bulgur.
"Multigrain", by contrast, simply means the product contains two or more grain species (for example, wheat, oats and barley). If the primary flour in the mixer is refined enriched white wheat flour with a handful of rolled oats and millet sprinkled on top—and caramel coloring or molasses added to turn the crumb brown—the loaf is legally "multigrain" while still being mostly refined flour.
- 100% Whole Grain / 100% Whole Wheat: All grain ingredients in the product retain their bran, germ and endosperm.
- Multigrain / 7-Grain / 12-Grain: Contains multiple grain types, which may be mostly refined enriched wheat flour unless each grain is specified as "whole".
- "Wheat bread" or "Stone-ground": "Wheat flour" without the word "whole" is ordinary refined white flour; "stone-ground" describes the millstone method, not whether the bran and germ were kept.
How to verify whole grains in the ingredient list in five seconds
Because front-of-pack badges can highlight a small percentage of whole grain, the most reliable check is the ingredient list on the back or side of the package, where ingredients are ordered by weight from most to least.
As Harvard's Nutrition Source advises, check that a whole grain—with the word "whole" right before the grain name (such as "whole wheat flour", "whole oats", "whole grain rye" or "brown rice")—is listed first (or second, right after water), and check that added sugars do not appear among the first three ingredients.
Using the 10-to-1 carbohydrate-to-fiber ratio benchmark on packaged foods
Harvard's Nutrition Source also highlights research comparing five different label criteria used to identify healthier whole-grain products (including front-of-pack stamps, which sometimes appeared on products higher in sugar and calories). Among the criteria evaluated, checking for a Total Carbohydrate-to-Dietary Fiber ratio of less than 10-to-1 (roughly matching the natural ratio of intact whole wheat) was the most effective indicator of products higher in fiber and lower in added sugars, sodium and trans fats.
To apply that check at the grocery store:
- Read the Total Carbohydrate grams per serving on the Nutrition Facts label and divide by 10.
- Check whether the Dietary Fiber line per serving is at least that number. Hypothetical math example: If a slice of bread has 20 g of Total Carbohydrate, look for at least 2 g (and ideally 3 g or more) of Dietary Fiber per slice.
- Whenever possible in home cooking, buy intact whole grains in bulk—such as brown rice, hulled barley, rolled oats, millet, buckwheat or 100% whole-wheat atta—where the only ingredient on the bag is the whole grain itself.
