Staple food crops from Brazilian Biofortification Program have high protein quality and hypoglycemic action in Wistar rats

Abstract

Biofortified staple food crops have become an effective tool by which to address micronutrient deficiencies in many at-risk populations. The effect of these food crops on the micronutrient status has been evaluated, however there is no studies investigating their protein quality, neither by themselves or in a food combination. Thus, this study investigated the effect of combinations of beans and rice, target for biofortification, with high carotenoids content crops (sweet potato and pumpkin) on protein quality, intestinal function and glycemia. Eight groups were evaluated (n=6): 1) rice + Caupi bean (RCB); 2) rice + Pontal bean (RPB); 3) rice + Caupi bean + pumpkin (RCBP); 4) rice + Pontal bean + pumpkin (RPBP); 5) rice + Caupi bean + sweet potato (RCBS); 6) rice + Pontal bean + sweet potato (RPBS); 7) casein (positive control); and 8) nitrogen free (negative control). Tested groups showed high protein quality, and groups containing Caupi bean showed higher true digestibility. Groups containing Pontal bean had a greater reduction of blood glucose compared to casein. Tested groups showed higher fecal excretion of lipids. Combination of food target for biofortification showed high protein quality, and the combinations containing Pontal beans showed hypoglycemic effect.Practical Application: The Biofortification program not only provide an additional amount of micronutrient but also contribute to the protein intake of the risk population and potentially improve the glycemic status and intestinal function. Thus, the utilization of these foods may have a positive impact on the nutritional status and health of population at risk for micronutrient deficiency. Dias et al.

Effect of heat-moisture treatment on physicochemical properties and digestive characteristics of sweet potato flour

“…In the HMT modification technology, there were few reports about the HMT on sweet potato powder, but there were more reports about the entire flour rich in cellulose, ascorbic acid, sweet potato polysaccharide, minerals, phenolic substances and aldehydes and experiments in functional foods (Santos et al, 2019;Kourouma et al, 2020;Cartier et al, 2017;Franco et al, 2020;Dias et al, 2020). Therefore, HMT may not only improve the stability of the sweet potato flour products and maintain the low digestion characteristics of starch, but also the nutritional and functional characteristics of the sweet potato flour will have an important impact on human health.…”

Isolation, purification and bioactivity of ACE inhibitory peptides from peach kernel protein enzymatic hydrolysate

“…Peaches as a source of food-derived proteins are mainly produced in China. However, most of peaches are discarded as wastes in peach processing industry (Koprivica et al, 2018;Ishimoto et al, 2020;Dias et al, 2020;Florêncio et al, 2020). Particularly, the annually yield of peach is about 5 million kilograms in Tibet of China.…”

Serum level of miR-217 predicts prognostic outcome for osteosarcoma patients in China

“…At present, the main treatment plan for osteosarcoma is primary tumor resection combined with preoperative and postoperative chemotherapy, which increases the 5-year survival rate of osteosarcoma patients to 60% to 70% (Marec-Berard et al, 2020;Schott et al, 2018;Vaseenon et al, 2017). It is reported that high protein diet has a certain effect on postoperative nursing of patients with osteosarcoma (Dias et al, 2020;Cordeiro et al, 2020;Gavião et al, 2021;Zhou et al, 2021). In recent years, the treatment strategy for osteosarcoma has been greatly improved, but the overall survival of osteosarcoma patients is still not optimistic, which is closely related to the relatively low clinical early diagnosis rate (Lin et al, 2019;Sugiura et al, 2018).…”
