A new study published in Nutrients, which analyzed the diets of more than 14,000 Americans over five years, found that both whole and refined grain foods play a role in improved diet quality, nutrient intake and everyday accessibility.
Obesity
Perspective: Does Glycemic Index Matter for Weight Loss and Obesity Prevention? Examination of the Evidence on “Fast” Compared with “Slow” Carbs (November 2021)
The glycemic index (GI) categorizes carbohydrates as “fast” (high-GI) or “slow” (low-GI) based on their impact on blood sugar levels. This review assessed whether dietary GI influences body weight and obesity risk using data from observational studies and meta-analyses of randomized controlled trials (RCTs).
Association between Grain Intake, Nutrient Intake, and Diet Quality of Canadians: Evidence from the Canadian Community Health Survey–Nutrition 2015 (August 2019)
Canada’s Food Guide emphasizes whole grains as the primary choice of grain products, but does higher whole-grain consumption always improve diet quality? This study analyzed nationally representative data from the Canadian Community Health Survey–Nutrition 2015 to explore the relationship between grain consumption, nutrient intake, diet quality, and obesity rates in Canadians.
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.
Prebiotic consumption and the incidence of overweight in a Mediterranean cohort: the Seguimiento Universidad de Navarra Project (December 2015)
Prebiotics, including fermentable and nondigestible carbohydrates like fructans and galacto-oligosaccharides (GOS), are believed to positively influence weight regulation by improving gut health. However, their role in preventing overweight or obesity has been underexplored in longitudinal studies. This study investigated the association between prebiotic intake and overweight incidence in a cohort of middle-aged Spanish university graduates.
Whole-grain foods and chronic disease: evidence from epidemiological and intervention studies (June 2015)
Whole-grain (WG) foods play a vital role in dietary recommendations, offering carbohydrates, protein, fiber, and key nutrients. Increased WG consumption is consistently linked to health benefits.
