A new study conducted by the University of Navarra within the project SUN (Seguimiento Universidad de Navarra) shows that the consumption of two or more servings per day of white bread (each serving is 3 slices) increases the risk of overweight/obesity by 40%, compared to those who choose to reduce this consumption to one serving per week.
The results were presented by Professors Miguel A. Martínez-González and Maira Bes-Rastrollo, from Preventive Medicine and Public Health, during the congress European Meeting on Obesity, held in Sofia, Bulgaria. network Both researchers are part of the research center Biomedical Center for the Pathophysiology of Obesity and Nutrition (CIBER-OBN).
Few programs of study have investigated the relationship between bread and obesity. In this research, the authors evaluated the relationship between white bread and weight change in a Mediterranean cohort from Spain, where white bread is the staple food.
The researchers followed a total of 9,267 university graduates from the project SUN over an average period of 5 years. At the beginning of the study, dietary habits were taken into account by conducting a validated food frequency questionnaire .
There is no association between eating whole wheat bread and being overweight.The results showed that joint consumption (white bread and whole wheat bread) was not associated with greater weight gain. On the contrary, the intake of only white bread was directly associated with an increased risk of overweight and obesity. Thus, participants who consumed two or more servings per day were 40% more likely to develop this disorder than those who consumed one serving per week or less.
No significant association was observed between whole grain bread consumption and overweight/obesity. "The nature of carbohydrates, the content of fiber and other micronutrients in whole-grain bread and the slower absorption of carbohydrates may explain the lack of association between consumption of whole-grain bread and obesity," the authors conclude.
