Within each of the four food groupings discussed above the
foods varied somewhat in the proportions of the carbohydrate fractions
that they contained. However, the average RAC, SDS and IDS
values for each of the food groupings (Fig. 2), showed a decreasing
proportion of RAC and increasing SDS as one moved across the food
groupings from A to D. The high IDS content typical of the pulses is
again evident.
