Described is use of Salvia hispanica L. (Chia) for controlling, in one embodiment reducing, blood glucose levels, preferably post-prandial blood glucose levels. This is useful in both non-diabetic and diabetic individuals, but especially in diabetic individuals. Also described is the use of chia in reducing postprandial blood glucose, insulin sensitivity, blood pressure, and oxidative stress in such individuals. The present invention further found that Chia can be used to improve endothelial function, coagulation, fibrinolysis and iron status. The present invention further encompasses the use of Chia in the treatment and/or management of diabetes and/or the treatment and management of diabetes associated conditions or risk factors, such as one or more of the following: blood pressure and blood glucose levels, post-prandial glycemia, inflammatory factors (C-reactive protein), coagulation (fibrinogen, factor VIII, von Willenbrand factor), and fibronolytic factors (such as t-PA), iron status and endothelial function, (such as increase in nitric oxide generation). In one embodiment the invention relates to dietary approaches to such treatment and management.
