How Sodium Boosts Diabetes Risk
Previous research has suggested that a diet high in sodium increases type 2 diabetes risk. Now, a new study provides more information about the connection between salt in the diet and an increased risk for diabetes and another metabolic condition called latent autoimmune diabetes in adults (LADA), which is often misdiagnosed as type 2 diabetes.
For the study, researchers from the Institute of Environmental Medicine at the Karolinska Institutet in Stockholm, Sweden and other Swedish and Finnish institutions analyzed data from the Epidemiological Study of Risk Factors for LADA and Type 2 Diabetes. The study involved 1,136 people with type 2 diabetes, 355 people diagnosed with LADA, and a healthy control group of 1,379 people. Researchers compared information about the participants' daily diets, including daily caloric, nutrient, and sodium intake, and determined their genetic risk for diabetes, controlling for such factors as body mass index (BMI), smoking status, and alcohol intake.
According to researchers, each extra gram of dietary sodium daily (about 2.5 grams of salt) increased type 2 diabetes risk by 43 percent and LADA risk by 73 percent. Results of the study were presented at the annual meeting of the European Association for the Study of Diabetes in Lisbon, Portugal.
