Whole Grains in the News Again!

Eating whole grains instead of refined grains may have benefits for your waistline, a new study suggests.

Adults who ate three or more servings of whole grains per day, and limited their refined grains to less than one serving per day, had 10 percent less belly fat than those who did not follow this diet, study researcher Nicola McKeown, a scientist with the USDA Human Nutrition Researcher Center on Aging at Tufts University, said in a statement.

The findings held true even after the researchers accounted for other facts that may have influenced the results, such as the participants' smoking, alcohol intake, fruit and vegetable intake, percentage of calories from fat and physical activity.

The study involved 2,834 men and women, ages 32 to 83, who filled out questionnaires about their diet. The participants also underwent body scans to determine their fat distribution — researchers measured how much fat was around the belly, so-called visceral fat, and how much was found in other parts of the body under the skin, known as subcutaneous fat.

Visceral fat is thought to be worse for you than subcutaneous fat. Previous work has linked belly fat with the development of metabolic syndrome, a cluster of symptoms including hypertension, unhealthy cholesterol levels and insulin resistance, which can develop into cardiovascular disease or Type 2 diabetes.

However, eating lots of whole grains didn't have the same benefits if people also consumed a lot of refined grains as well. Those who ate more than four servings of refined grains per day did not show improvements in their visceral fat volumes even if they also consumed whole grains, McKeown said.

"This result implies that it is important to make substitutions in the diet, rather than simply adding whole grain foods. For example, choosing to cook with brown rice instead of white, or making a sandwich with whole-grain bread instead of white bread," McKeown said.

The researchers noted the study only shows an association, and future work in a larger, more diverse population will be needed to confirm the findings.

This study was funded by the National Heart Lung and Blood Institute, the USDA and a research grant from the General Mills Bell Institute of Health and Nutrition.

Looking for More Whole Grains?

Adding more whole grains to your diet is good advice, especially for athletes. Now it will be even easier to find this important carbohydrate in your favorite grocery store.

Kraft Foods has announced plans to double the amount of whole grain in its Nabisco-brand crackers, as Americans continue to struggle to consume their recommended three servings of whole grain a day.


Most Americans only get about one serving of whole grains each day, meaning that they could be missing out on some key nutrients such as fiber, B vitamins, iron and magnesium, Kraft said.


Kraft’s president of global health and wellness Rhonda Jordan said: “Nine out of ten Americans eat less than the recommended daily amount of whole grains. And a growing number of consumers are trying to increase their consumption of whole grains. By significantly increasing the amount of whole grain in our crackers, we're giving them an easy, delicious way to get the whole grain they need in the foods they already enjoy."


The company said it would increase whole grain in more than 100 products over the next three years, including:


Doubling the amount of whole grain in Original Wheat Thins from 11g to 22g per serving;
More than tripling the amount in Wheat Thins Toasted Chips from 5g to 17g per serving;
Quadrupling the amount in Honey Maid Original Graham Crackers from 5g to 20g per serving;
And adding whole grain to Premium and Ritz crackers.
