Research Refutes Refined Grains’ Bad Rep

It’s no secret that whole grains are good for us. Dietary guidance tells us to “make half our grains whole,” cereal boxes and bread bags tout their whole grain goodness, and news headlines repeat the message. And indeed, whole grains do provide a host of health benefits — for example, the dietary fiber that they deliver supports a healthy heart, gut, and even weight by helping you feel full between meals.

But what about “the other half,” refined grains? Thanks to a misleading mix of media coverage, research, and dietary guidance, you’ve probably heard that they are something to completely avoid, or at least severely limit, in a healthy diet.

However, an in-depth review of recent published research on both whole and refined grains highlights the importance of including – and risks of excluding – enriched refined grains as part of a healthy diet. Furthermore, the study suggests that consumers should be careful not to take current “make-half-your-grains-whole” dietary guidance to mean that their six daily servings of grain foods should not include refined or enriched grain foods, which have been fortified to help to alleviate shortfalls of critical nutrients including B-vitamins, thiamin, niacin, riboflavin, iron, and folic acid.

In this episode, study co-authors Dayle Hayes, an award-winning child nutrition expert, and Dr. Glenn Gaesser, a leader in nutrition research, provide listeners with an overview of their findings related to the benefits of including and risks of excluding grain foods from the diet; health outcomes; dietary guidance; and areas for future research.

• How many Americans are meeting (or not meeting) recommended fiber intake
• What are “shortfall nutrients”
• What does the “make half your grains whole” recommendation mean
• The history of grains research
• The consensus statement research and findings
• Takeaways for the public, researchers and health professionals

Less than 1 in 10 Americans consume the recommended 25-30 grams of daily fiber. But the good news is that  grains provide more than 40% of fiber in the American diet and 2/3 of that fiber comes from enriched grain products.” – Dr. Glenn Gaesser
