In a new study from the University of Eastern Finland, researchers found increased consumption of whole-grain foods could significantly reduce the incidence of type 2 diabetes and the costs associated with its treatment.

They found that already one serving of full grains as part of the daily diet reduces the incidence of type 2 diabetes at the population level and, consequently, the direct diabetes-related costs, when compared to people who do not eat whole-grain foods on a daily basis.

Type 2 diabetes is one of the fastest-growing chronic diseases both in Finland and globally. Healthy nutrition that supports weight management is key to preventing type 2 diabetes.

The association of daily consumption of whole-grain foods with a lower risk of diabetes has been demonstrated in numerous studies.

According to nutrition recommendations, at least 3–6 servings of whole-grain foods should be eaten daily, depending on an individual’s energy requirement.

One third of Finns do not eat even one dose of whole grains on a daily basis, and two-thirds have a too low fiber intake.

In the study, the team utilized findings from, e.g., national follow-up studies, such as the FinHealth Study, to assess the health and economic effects of increased consumption of whole-grain foods on the prevention of type 2 diabetes.

They were able to assess the potential health and economic benefits from both social and individual viewpoints.
