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.
Dietary fibre and incidence of type 2 diabetes in eight European countries: the EPIC-InterAct Study and a meta-analysis of prospective studies (May 2015)
Dietary fiber has long been associated with reduced risks of chronic diseases, including type 2 diabetes (T2D), but few European studies have evaluated this relationship. This research analyzed data from the EPIC-InterAct cohort across eight countries and combined it with a meta-analysis of 19 prospective studies to investigate the link between fiber intake and T2D risk.
