Dietary guidelines encourage consumers to “make half their grains whole,” yet debates continue about refined grains and grain-based foods (GBFs). This article counters misconceptions, advocating for a balanced intake of whole-grain foods (WGFs) and refined-grain foods (RGFs).

Grain Foods in US Infants Are Associated with Greater Nutrient Intakes, Improved Diet Quality and Increased Consumption of Recommended Food Groups (November 2019)
Grain foods may play an essential role in the diets of U.S. infants, according to an analysis of infant data from the National Health and Nutrition Examination Survey (NHANES). The study examined relationships between grain consumption, nutrient intake, diet quality, and food group consumption among infants aged 6 to 23 months.
Perspective: Refined Grains and Health: Genuine Risk, or Guilt by Association? (May 2019)
Refined grains are often implicated in adverse health outcomes, including cardiovascular disease (CVD), type 2 diabetes (T2D), and obesity, largely based on dietary pattern studies. This perspective challenges the assumption that refined grains are inherently harmful, emphasizing the need to distinguish refined grains from other elements of the Western dietary pattern.
Carbohydrate quality and human health: a series of systematic reviews and meta-analyses (February 2019)
This report analyzed data from 185 prospective studies and 58 clinical trials, representing nearly 135 million person-years, to evaluate the relationship between carbohydrate quality and health outcomes. It examined dietary fiber, whole grains, and glycemic measures in relation to non-communicable diseases.
Grains Contribute Shortfall Nutrients and Nutrient Density to Older US Adults: Data from the National Health and Nutrition Examination Survey (NHANES), 2011–2014 (April 2018)
The 2015–2020 Dietary Guidelines for Americans have identified several shortfall nutrients in the U.S. population, including fiber, folate, and iron (women only). Intake of some shortfall nutrients can be even lower in older adults. The present analyses determined the contribution of grain foods for energy and nutrients in older U.S. adults and ranked to all other food sources in the American diet.
Grain Foods Are Contributors of Nutrient Density for American Adults and Help Close Nutrient Recommendation Gaps: Data from the National Health and Nutrition Examination Survey (NHANES), 2009–2012 (August 2017)
This analysis examined the role of grain foods in providing energy and nutrients for U.S. adults using data from the National Health and Nutrition Examination Survey (2009–2012). Grain foods were analyzed for their contributions to both total energy and shortfall nutrients identified by the 2015–2020 Dietary Guidelines for Americans (DGA), including dietary fiber, folate, iron, and magnesium.
