Diabetic patients at high risk for cardiovascular disease with high salt diet.

saltDiabetes has become a public health risk with an estimated 29.1 millions Americans suffering from some of diabetes. In a study published in the journal of Clinical Endocrinology & Metabolism Type 2 diabetes patients had twice the risk of developing cardiovascular disease as those who consume less sodium.

The Centers for disease Control and Prevention, CDC, has tracked the death rates associated with cardiovascular events and determined that cardiovascular disease death rates were about 1.7 times higher among adults diagnosed with diabetes than those who were not. Study participants were identified at 59 outpatient centers and universities across Japan with a total of 1,588 people responding to a survey about their diets, including sodium intake. Participants were tracked over an eight year period and researchers divided the participants into four groups based on their sodium intake. The research findings determined that people who ate an average of 5.9 grams of sodium daily had double the risk of developing cardiovascular disease than those who ate, on average, 2.8 grams of sodium daily. The effects of a high-sodium diet were exacerbated by poor blood sugar control.

“The study’s findings provide clear scientific evidence supporting low-sodium diets to reduce the rate of heart disease among people with diabetes,” said the study’s first author, Chika Horikawa, RD, MSc, CDE, of the University of Niigata Prefecture in Niigata, Japan. “Although many guidelines recommend people with diabetes reduce their salt intake to lower the risk of complications, this study is among the first large longitudinal studies to demonstrate the benefits of a low-sodium diet in this population.”

“To reduce the risk of developing cardiovascular disease, it is important for people who have Type 2 diabetes to improve their blood sugar control as well as watch their diet,” Horikawa said. “Our findings demonstrate that restricting salt in the diet could help prevent dangerous complications from diabetes.”
