For the purpose of enriching the knowledge on the glycaemic (GI) and insulinaemic (InIn) indices of indigenous foods, 3 single foods and 3 realistic high complex carbohydrate meals (bread=100) were studied in 8 healthy subjects. Observed GI (mean+/-SEM) were: beans (B) 19.3+/-3.4, wheat tortilla (WT) 42.5+/-6.9, corn tortilla (CT) 73.8+/-6.5, wheat tortilla beans taco (BWT) 39.9+/-12.8, corn tortilla beans taco (BCT) 56.2+/-8.2 and corn tortilla potato taco (PT) 111.0+/-11.5. The glycaemic index of all foods was lower than white bread (WB) (p
