“…The amount of protein and non-protein nitrogen should also be assessed (Chater et al, 2015). Consequently, the protein rate of a specific diet is calculated by its essential amino acids and its biological result depends on the protein´s digestibility (Alves et al, 2008).…”

Pereskia aculeata Mill., a species of the family Cactaceous, popularly known in Brazil as ora-pro-nobis, has high protein, vitamin and mineral contents. High essential amino acid concentrations should be underscored, suggesting a better evaluation of the fractions. Current study quantifies amino acid content and the chemical score (CS) of protein amino acids, determining in vivo digestibility, protein efficiency ratio (PER) and net protein ratio (NPR) of P. aculeata. Plant material was collected, washed, placed in an oven at 60 °C, ground and stored in a freezer for chemical analysis. Diets that maintain isoproteic and isocaloric characteristics were prepared for the bioassay, namely: casein (no protein) and Pereskia aculeata leaves-based flour. Eighteen male albino Wistar rats, divided into three experimental groups of 6 animals each, were used to evaluate protein quality and bioavailability of micronutrients. Pereskia aculeata flour provided as a single source is inadequate for growth, although it is relevant for maintaining protein metabolism indicated by net protein ratio (2.87). It is actually a good quality protein source due to few limiting essential amino acids, and it meets the diet requirements for humans.Keywords: Ora-pro-nobis; protein quality; digestibility; PER; NPR; PDCAAS.Practical Application: Pereskia aculeata when provided as a single source is not adequate for proper growth, however it is important the adequacy of maintaining the protein metabolism indicated by net protein ratio. During the experiment, animals fed on Pereskia aculeata gained less weight when compared with animals fed on casein, mean weekly feed consumption was also low. And it is a good protein source good quality due to present few limiting essential amino acids and thus are able to meet the needs for the diet in humans.

“…The small intestine is the major site of adsorption in human body, not only for nutrients but also for toxins (Chater and others ). Hence, adsorption capacity of toxic ions, bile acid salts, and fat of SDFs from the root, stem, and leaf of Angelica keiskei were determined in vitro to simulate environment of the small intestine (Table ).…”

This study comparatively investigated the functional properties, chemical compositions, and morphological characters of soluble dietary fibers (SDFs) from the root, stem, and leaf of Angelica keiskei. The SDFs showed relevant functional properties, with the root SDF (RSDF) exhibiting the highest water-holding capacity (22.6 g/g), oil-holding capacity (6.29 mL/g), swelling capacity (36.6 mL/g), emulsion stability, and fat adsorption (5.66 g/g). Stem SDF (SSDF) gave the highest foam stability, toxic ions adsorption (Pb: 1.12 mg/g; As: 3.22 mg/g), and bile acid salts adsorption (sodium cholate: 85.6 mg/g; sodium glycocholate: 93.1 mg/g; sodium taurocholate: 125.7 mg/g). RSDF and SSDF presented similar monosaccharide compositions, thermal property, chemical bonds and groups, and irregular, rough, and porous surfaces. It can be concluded that the obtained SDFs, especially for RSDF and SSDF, can be used in the food industry as fiber-rich functional ingredients.

“…Soluble fiber can reduce the rate and extent of nutrient absorption in the small intestine . This nutrient absorption control of fiber on other nutrients includes sugars, which thus supports blood glucose control .…”

“…This might be because glucose appears in different forms in the diet (indigestible and digestible starch, dextrins, oligosaccharides, disaccharides, and as the free monosaccharide). Any restriction in the digestion of α‐glucans to provide blood glucose (unlike ingested mono‐saccharide), may in part be due to inhibition of the activity of α‐amylase . However, some studies do indicate that the viscosity of soluble fiber (e.g., konjac glucomannan) in the small intestine restricts glucose absorption directly .…”

There are many checks and balances in the body that regulate the recovery of energy from sugars and starches in the presence of non-starch polysaccharides. This mini-review seeks to consider those factors, pertaining to the presence of dietary fiber that may interact with starch digestion and the absorption of sugars in the diet. Biochemical, nutritional and physiological aspects are considered. The influences of fiber in the diet are multifunctional and the layers of interaction within the stomach and small intestine are considered.
