Beyond the nutritional value, legumes and particularly common beans are found in several dietary supplements used to treat diabesity (diabetes and obesity). These products contain not only inhibitors of carbohydrate-hydrolising enzymes (alpha-amylase, alpha-glucosidase), but also antinutritional factors that can cause adverse effects on human health. In the present research, twenty-two accessions of grain legumes were screened for bioactive (alpha-amylase and alpha-glucosidase inhibitors) and antinutritional (lectins, flatulence-producing sugars, trypsin inhibitors) phytochemicals. Results showed that four accessions had high alpha-amylase inhibiting activities (AI > 30%), and particularly the common bean 'Great Northern' resulted of interest for its high carbo-blocker activity (AI = 42.6 +/- 0.5%), absence of lectins, low amounts of flatulence-producing oligosaccharides (2.5 +/- 0.2 g/100 g DW) and low anti-trypsin activity (22.5 +/- 4.3 trypsin inhibiting unit/mg DW). The knowledge offered from this work provides leads to the ultimate goal of developing new, more effective and safer dietary supplements for diabesity management.
