All bran vs corn flakes: plasma glucose and insulin responses in young females.
Plasma glucose and insulin responses to breakfasts containing all bran or corn flakes were determined in 11 normal female volunteers aged 21-27 y. The test meals provided 50 g egg, 133 g orange juice, 129 g 2% milk, 180 g coffee, 5 g margarine, and 30 g available carbohydrate from either all bran or corn flakes with 19 g or 1 g of dietary fiber, respectively. Plasma glucose and insulin responses were higher for the corn flake breakfast and the incremental area under the glucose curve was 40% greater than that for the all bran breakfast (t test, p less than 0.05). These results are consistent with the reported glycemic indices for these cereals when consumed alone but the glucose responses differ to a lesser degree when the cereals are ingested with other foods. Thus, in this group of well-defined subjects the effect of all bran and corn flakes on plasma glucose responses is attenuated when these cereals are incorporated into mixed meals.
