BACKGROUND Studies of whole grain and chronic disease have often included bran-enriched foods and other ingredients that do not meet the current definition of whole grains. Therefore, we assessed the literature to test whether whole grains alone had benefits on these diseases. OBJECTIVE The objective was to assess the contribution of bran or cereal fiber on the impact of whole grains on the r...

Dietary guidance universally supports the importance of grains in the diet. The United States Department of Agriculture pyramid suggests that Americans consume from six to 11 servings of grains per day, with three of these servings being whole grain products. Whole grain contains the bran, germ and endosperm, while refined grain includes only endosperm. Both refined and whole grains can be fort...

OBJECTIVE To explore current awareness and perceptions of whole grain foods and perceived barriers and facilitators of whole grain consumption. DESIGN Focus groups were conducted to investigate consumer attitudes to whole grains. Discussions were transcribed verbatim and analysed thematically. SETTING Discussions were held throughout Northern Ireland with adults who were at least partly res...

BACKGROUND The consumption of whole grains and its association with nutrient intake has not been assessed in a recent nationally representative population. OBJECTIVE To examine the association of consumption of whole grains, using the new whole-grain definition, with diet quality and nutrient intake in a recent, nationally representative sample of adults. DESIGN Secondary analysis of cross-...

Background: Obesity in Canadian adults is showing upward trends. Consumption of whole-grains is one recommendation for the prevention of obesity. Despite the apparent nutritional and energy content differences between whole and refined grains, knowledge relating refined grains to weight gain in Canadian adults is scarce. The aim of this study was to assess the consumption of specific grain-base...

The finding that people who eat the most whole grains have a lower risk of cardiovascular disease and diabetes, compared with those who eat the least, is one of the most consistent findings in nutritional epidemiology. However, criteria for reporting whole-grain intake have varied widely, making it difficult to precisely explore the relation of whole grains and grain components with health outc...

INTRODUCTION Whole-grain consumption reduces risk of chronic disease, yet adolescents consume suboptimal amounts. It is unclear whether trends in consumption of whole grains have been positive among adolescents, and research assessing disparities by socioeconomic status is limited. The objective of our study was to evaluate recent trends in whole-grain consumption by US adolescents. METHODS W...

The U.S. FDA defines whole grains as consisting of the intact, ground, cracked, or flaked fruit of the grains whose principal components, the starchy endosperm, germ, and bran, are present in the same relative proportions as they exist in the intact grain. We evaluated the effect of applying the FDA definition of whole grains to the strength of scientific evidence in support of claims for risk ...

Varietal purity and proportions of grains with brown spots, fissured grains, chalky grains andwhole grains in a rice sample are important grain quality attributes influencing consumers'preference and price but little information exist on how these grain quality attributes are affectedby biophysical factors and pre-harvest practices. Several authors have studied in isolation theeffect of biophys...

Alkylresorcinols (ARs) were first proposed as potential biomarkers of wholegrain wheat and rye intake a decade ago. Since then there has been a considerable body of research which suggests that ARs do meet most criteria of a biomarker of these foods. Results from human studies on plasma AR and their plasma and urinary metabolites strongly indicate that these compounds are responsive to whole gr...
