Nonetheless, both amylose and
lactulose breakfasts were effective in improving the glucose tolerance of a second meal.
Not exact matches
Mean (± SE) insulin concentrations during the test period after the high - glycemic - index (HGI; •), low - glycemic - index (LGI; ▪), and HGI with
lactulose (HGI - Lac; ▴)
breakfasts.
We enhanced the colonic fermentation of an HGI amylopectin
breakfast meal by adding
lactulose, a soluble disaccharide that boosts colonic fermentation but that, because it is nonviscous, should not affect the GI of the food to which is added.
During the postbreakfast period, the HGI - Lac
breakfast, which included amylopectin starch and
lactulose, gave a glycemic response comparable to that after the HGI
breakfast, but, during the postlunch period, it resulted in lower glycemic profiles, similar to those obtained after the LGI
breakfast but significantly different from those after the HGI
breakfast, at the 8th (P < 0.01) and 9th (P < 0.05) hours.
In particular, the SME of a completely and rapidly digestible
breakfast containing amylopectin starch with or without added the fermentable disaccharide
lactulose was compared with that of a slowly digestible
breakfast meal containing high - amylose starch, in which, besides being slowly digested, some of the starch would escape small - intestine digestion and be fermented in the colon.
The average peak H2 values of ≈ 18 and ≈ 26 ppm reached at the 7th hour for LGI and HGI - Lac, respectively were in keeping with the expected degree of fermentation of the resistant starch and
lactulose consumed during
breakfast (7, 8).
Mean (± SE) breath - hydrogen concentrations during the test period after the high - glycemic - index (HGI; •), low - glycemic - index (LGI; ▪), and HGI with
lactulose (HGI - Lac; ▴)
breakfasts.
The purified fiber used for the LGI
breakfast and for 1 of the 2 HGI
breakfasts was a preparation of nonfermentable purified cellulose from hazelnut shells (ALSO, Zelbio, Italy), whereas, in the second HGI
breakfast, the HGI - Lac meal, cellulose was replaced with 5 g of the undigestible and highly fermentable disaccharide
lactulose in crystalline form (INALCO, Milan, Italy).
Mean (± SE) glucose concentrations during the test period after the high - glycemic - index (HGI; •), low - glycemic - index (LGI; ▪), and HGI with
lactulose (HGI - Lac; ▴)
breakfasts.
Mean (± SE) nonesterified fatty acid (NEFA) concentrations during the test period after the high - glycemic - index (HGI; •), low - glycemic - index (LGI; ▪), and HGI with
lactulose (HGI - Lac; ▴)
breakfasts.
