Looking into the Whole Grain Puzzle
Study finds clues on why certain grains are such a good fit
In recent decades, scientists have shown a probable link between eating whole grains like oats and rye and reducing the risk of certain maladies, including type 2 diabetes and heart disease. Now we may know one important way in which whole grains help to stave off the Grim Reaper.
A study led by the University of Eastern Finland and published last year in The American Journal of Clinical Nutrition found that after consuming a whole-grain-rich diet for 3 months, subjects showed upticks in various betaine compounds—pipecolic acid, for example—in their bodies. This, in turn, reduced postmeal blood sugar levels and improved other markers of glucose metabolism.
One theory is that microbes in our gut feed on elements of whole grains (e.g., fiber) to produce beneficial substances such as betaines that work on a cellular level to improve health measures. Now, that’s a good reason to shelve the white bread in favor of something more wholesome.
WHOLE-GRAIN CONFUSION - Consumers are often misled by labels, study finds.
Many health experts urge us to eat more whole grains; the mixture of fiber, nutrients and antioxidants may lower the risk for several chronic ailments. (“Whole-grain” means the grain contains the original endosperm, germ and bran, hence delivering a bigger nutrition payload.) However, you could spend hours at the supermarket analyzing all the bread, crackers, cereal and other products that tout themselves as “whole-grain” on the label and still come home with fewer whole grains than you’d planned.
Out of 1,030 participants in a Public Health Nutrition study, 51% overestimated the whole-grain content in a sampling of 12-grain bread products, and 41% overestimated the whole-grain count in multigrain crackers—all of which had whole-grain lingo on the front of the package. When then trying to select the healthiest options from a list of hypothetical grain products with terms like “multigrain” and “made with whole grains” on the labels, respondents answered incorrectly 29%–47% of the time.
The reason why consumers remain flummoxed in the bread aisle is that manufacturers have a plethora of ways to persuade us that a product has a higher whole-grain content than it actually does. For instance, they can tell us it’s multigrain when, in fact, it’s mostly made with refined flour. “Made with whole grains” means the food contains some amount of whole grain, but not that the food is entirely whole-grain. So instead of relying on marketing to tell us how “healthy” a food item is, we need the skills to discern true healthfulness—by scanning ingredient lists, for a start. Seeking out products flaunting the regulated term “100% whole-grain” helps, too. There is also the opportunity for more regulation of food labels, to help stamp out misleading sales pitches.
