Inclusion of Whole Flour from Latin-American Crops into Bread Formulations as Substitute of Wheat Delays Glucose Release and Uptake
Bakery formulations limiting glucose availability for uptake without compromising product quality are required. Herein, bread formulations containing whole flour from Amaranthus hypochondriacus (AB), Chenopodium quinoa (QB), Salvia hispanica L (ChB) or wheat (WWB) were compared to white bread (WB) f...

| Sumario: | Bakery formulations limiting glucose availability for uptake without compromising product quality are required. Herein, bread formulations containing whole flour from Amaranthus hypochondriacus (AB), Chenopodium quinoa (QB), Salvia hispanica L (ChB) or wheat (WWB) were compared to white bread (WB) for glycaemic index (GI) in fasted animals. The hepatic expression (mRNA) of PPAR-γ receptor as key regulator in substrate fractionation towards energy expenditure was monitored. GIs were associated to fluxes of glucose release (FGluc) and metabolic response (MTT assay) of HepG2 cells. ChB (19.7%) and AB (13.5%) decreased GI to a higher extent than QB (2.7%), but all increased expression of PPARγ in relation to WB. FGluc (AB> > ChB, WWB, WB > QB) showed a reciprocal relationship with the area under curve (AUC) in vivo, and decreased MTT conversion values (WB > WWB, ChB, AB, QB) by HepG2 cells. Thus, inclusion of latin-american crops (LAcs) reducing GI, without compromising bread quality, could help preventing metabolic diseases. |
