Diets with high glycaemic index and high glycaemic load linked to incident diabetes: PURE trial
In a landmark study spanning five continents, researchers have uncovered a significant association between dietary carbohydrate quality and the risk of developing type 2 diabetes. The findings, published in the renowned scientific journal, underscore the critical role of diet in preventing this increasingly prevalent metabolic disorder. individuals who consumed diets characterized by elevated glycemic index (GI) and glycemic load (GL) faced an increased likelihood of developing type 2 diabetes within a diverse multinational cohort representing five continents.
The study results were published in the journal The Lancet: Diabetes & Endocrinology.
The relationship between glycemic index (GI) and glycemic load (GL) and the onset of type 2 diabetes is subject to debate. Hence, researchers conducted a study with to assess this connection within a multinational cohort characterized by varying levels of GI and GL in their diets. The study, known as the Prospective Urban Rural Epidemiology (PURE) study, involved a vast cohort of 127,594 adults aged 35-70 from 20 countries across diverse economic backgrounds. Led by an international team of scientists, the research aimed to evaluate the impact of dietary glycemic index (GI) and glycemic load (GL) on the incidence of type 2 diabetes. Using validated food frequency questionnaires, the researchers assessed participants' diets at the outset of the study, estimating GI and GL based on the intake of seven categories of carbohydrate-containing foods. Over a median follow-up period of 11.8 years, 7326 cases of incident type 2 diabetes were recorded, providing a robust dataset for analysis.
