Sodium intake may be linked to an increased risk of developing both type 2 diabetes (T2D) and Latent Autoimmune Diabetes in Adults (LADA) says new research being presented at this year’s annual meeting of the European Association for the Study of Diabetes (EASD) in Lisbon, Portugal.
The main source of sodium in the diet is through salt. Salt (sodium chloride) is 40% sodium, so that for every 2.5 g of salt consumed, 1 g is sodium. Previous research has suggested that excessive salt consumption may increase the risk of developing T2D, possibly through a direct effect on insulin resistance, and/or by promoting high blood pressure and weight gain.
The study found that sodium intake was associated with an average 65% increase in the risk of developing T2D for each extra gram consumed per day. The effect of sodium intake on the risk of developing LADA was even greater, with a 82% rise for each gram consumed per day. The authors suggest that “These findings may have important implications in the primary prevention of diabetes with adult onset”.
