The present invention relates to a stabile cereal-based food suspension that has been prepared by a) heat-treating a mixture of beta- glucan-rich cereal material and water to gelatinize the starch contained in the cereal material to form a suspension; b) by cooling the heat-treated suspension; and c) by grinding the cooled suspension to form a stabile food suspension, the food suspension having a beta-glucan concentration of at least 0.25 g/100 g of food suspension. Further, the invention concerns a method for preparing a food suspension, as well as use of a food suspension.
