ABSTRACT: The “bai?o de dois”
is a typical Brazilian dish and a rich combination of rice and beans. This preparation
has a high nutritional value but its effect on glycemic response is not yet
studied. To determine the glycemic index and glycemic load of foods can help
prescribing diets and as a result, improving the treatment and prevention of
chronic diseases. This study aimed to access the glycemic index (GI) and
glycemic load (GL) of “bai?o de dois”. Following the protocol recommended by
the Food and Agriculture Organization, 6 volunteers were recruited to perform
blood glucose tests. Each volunteer performed three glucose tolerance tests and
a test with “bai?o de dois”. All tests were undertaken in separate weeks.
Through the calculation of the areas under each of the curves, it was possible
to access the GI of “bai?o de dois” by the average values of six GIs found for
each volunteer. It was calculated that the GL of each portion tested and
recommended servings per capita. It was found that “bai?o de dois” had low GI
(44) and GL (6) at the recommended per capita, but high GL (22) at the portion
tested (bigger than the recommended). The “bai?o de dois” do not present a
potential risk for developing chronic diseases, but it is recommended
consumption to be monitored.
