Plasma glucose response and glycemic indices in pigs fed diets differing in in vitro hydrolysis indices

摘要: Different dietary starch sources can have a great impact in determining digestion potential, thus influencing the postprandial blood glucose response. Our objectives were to define: (i) incremental plasma response pigs fed diets containing various of differing vitro patterns, (ii) vivo glycemic index (GI) values for same diets, (iii) possible relationship between and data. Diets, formulated with 70% from five heterogeneous sources, characterized depth by using two distinct evaluations. The first one was based on Englyst-assay nutritional classification fractions, whereas second time-course multi-enzymatic assay up 180 min which hydrolysis indices (HIs) calculated used as link physicochemical properties responses. For study, jugular-catheterized (35.3 ± 1.1 kg body weight) 6-day periods 5 × Latin square design. On day 5, collected 8 h postprandially evaluating appearance. 6, 3 estimation GI. Starchy differed rapidly digestible (from 8.6% 79.8% total (TS)) resistant contents 72.5% 4.5% TS). Wide between-diets variations recorded all kinetic parameters HI curves (P < 0.05). basis obtained HI, contained very low high potential (ranging 26.7% 100.0%; P among 0.05), marked differences 15 120 postprandial. Overall, ranking appearance agreed their classification: increased more 0.05) than diets. Lastly, different GIs measured 30.9% GI showed coefficient determination (R2 = 0.95; root mean error (RMSE) 15.8; In conclusion, starches wide range strongly affect pigs.
