Studies of low levels of barley consumption (1 to 2 grams) found that acute
reduction of the glycemic response and hunger ratings in overweight women
required consumption of at least 2 grams and 1 gram of beta-glucan per meal,
respectively. However, in overweight men greater amounts of beta-glucan per meal
is likely to be required for substantial glucose and satiety rating effects.
This study
further suggests the beneficial effects of beta-glucan on glucose metabolism and,
possibly, satiety. This work was published in Cereal Foods World.
