Consumption of soy has increased in Western countries due to the benefits on health and the attitude of the people to consume natural products as alternative to the use of pharmacological therapies. However, there is no evidence whether the consumption of 25 g of soy protein as recommended by the Food and Drug Administration has some effect on glucose absorption and consequently on insulin secretion. The aim of the present study was to determine glycemic index (GI), insulinemic index (InIn), and glycemic load (GL) of several soy beverages containing low or high concentration of carbohydrates, and compare them with other foods such as peanuts, whole milk, soluble fiber and a mixed meal on GI and InIn. The results showed that soy beverages had low or moderate GI, depending of the presence of other compounds like carbohydrates and fiber. Consumption of soy beverages with low concentration of carbohydrates produced the lowest insulin secretion. Therefore, these products can be recommended in obese and diabetic patients. Finally soy beverages should contain low maltodextrins concentration and be added of soluble fiber.
