Great Northern Beans (Phaseolus vulgaris L.) Lower Cholesterol in Hamsters Fed a High-Saturated-Fat Diet

Jatobá-do-cerrado (Hymenaea stigonocarpa Mart.) pulp positively affects plasma and hepatic lipids and increases short-chain fatty acid production in hamsters fed a hypercholesterolemic diet

This study aimed to assess the impact of jatobá pulp, in its fresh (FJ) and extruded (EJ) forms, on lipid metabolism and intestinal fermentation parameters in hamsters. In a 21-day experiment, we determined the parameters of the animal lipid metabolism and colonic production of short chain fatty acids in four different groups. Control (C), fresh pulp (FJ) and extruded pulp (EJ) were fed using hypercholesterolemic diets, and the reference (R) was fed using AIN93 meal. R and C diets contained cellulose, FJ and EJ were added by jatobá pulp as a fiber source. The results showed that FJ and EJ exhibited lower levels of triglycerides, total cholesterol, LDL-c, non-HDL-c serum levels, liver lipids, and liver weight compared to C. The EJ had higher bile acid excretion in stool than the C. EJ and FJ exhibited lower excreted fiber compared to R and C, implying greater fermentation. Furthermore, the production of short-chain fatty acids (SCFA) in the cecum of FJ and EJ animals exceeded that of the C. Acetic and propionic acids were more abundant in the FJ and EJ diets, with FJ producing more butyric acid than the other groups.In conclusion, jatobá pulp maintained at normal levels of total cholesterol, LDL and HDL-associated cholesterol, non-HDL cholesterol, and serum triglycerides, while also reducing the accumulation of hepatic lipids. Jatobá also promoted SCFA formation and fermentation, making it a valuable ingredient for preventing chronic diseases.

The Non-Nutritional Factor Types, Mechanisms of Action and Passivation Methods in Food Processing of Kidney Bean (Phaseolus vulgaris L.): A Systematic Review

Kidney beans (KBs), as a traditional edible legume, are an important food crop of high nutritional and economic value worldwide. KBs contain a full range of amino acids and a high proportion of essential amino acids, and are rich in carbohydrates as well as vitamins and minerals. However, KBs contain a variety of non-nutritional factors that impede the digestion and absorption of nutrients, disrupt normal metabolism and produce allergic reactions, which severely limit the exploitation of KBs and related products. Suppressing or removing the activity of non-nutritional factors through different processing methods can effectively improve the application value of KBs and expand the market prospect of their products. The aim of this review was to systematically summarize the main types of non-nutritional factors in KBs and their mechanisms of action, and to elucidate the effects of different food processing techniques on non-nutritional factors. The databases utilized for the research included Web of Science, PubMed, ScienceDirect and Scopus. We considered all original indexed studies written in English and published between 2012 and 2023. We also look forward to the future research direction of producing KB products with low non-nutritional factors, which will provide theoretical basis and foundation for the development of safer and healthier KB products.

Common beans as a source of food ingredients: Techno-functional and biological potential

Common beans are an inexpensive source of high-quality food ingredients. They are rich in proteins, slowly digestible starch, fiber, phenolic compounds, and other bioactive molecules that could be separated and processed to obtain value-added ingredients with techno-functional and biological potential. The use of common beans in the food industry is a promising alternative to add nutritional and functional ingredients with a low impact on overall consumer acceptance. Researchers are evaluating traditional and novel technologies to develop functionally enhanced common bean ingredients, such as flours, proteins, starch powders, and phenolic extracts that could be introduced as functional ingredient alternatives in the food industry. This review compiles recent information on processing, techno-functional properties, food applications, and the biological potential of common bean ingredients. The evidence shows that incorporating an adequate proportion of common bean ingredients into regular foods such as pasta, bread, or nutritional bars improves their fiber, protein, phenolic compounds, and glycemic index profile without considerably affecting their organoleptic properties. Additionally, common bean consumption has shown health benefits in the gut microbiome, weight control, and the reduction of the risk of developing noncommunicable diseases. However, food matrix interaction studies and comprehensive clinical trials are needed to develop common bean ingredient applications and validate the health benefits over time.

In vitro Digestion of Phaseolus vulgaris L. Cooked Beans Induces Autophagy in Colon Cancer Cells

Phaseolus vulgaris L. (common bean) contains high levels of proteins, unsaturated fatty acids, minerals, fibers, and vitamins, and for this reason, it represents an essential component of the diet. More than 40,000 varieties of beans have been recognized and are staple foods in the traditional cuisine of many countries. In addition to its high nutritional value, P. vulgaris is also characterized by its nutraceutical properties and favors environmental sustainability. In this manuscript, we studied two different varieties of P. vulgaris, Cannellino and Piattellino. We investigated the effects of traditional processing (soaking and cooking) and in vitro gastrointestinal digestion of beans on their phytochemical composition and anticancer activity. Using HT29 and HCT116 colon cancer cell lines, we showed that the extract obtained after gastrointestinal digestion of cooked beans (the bioaccessible fraction, BF) induces cell death through the induction of the autophagic process. We demonstrated that the BF of Cannellino and Piattellino beans at the concentration of 100 μg/mL reduces cell vitality, measured by MMT assay, of both HT29 (88.41% ± 5.79 and 94.38% ± 0.47) and HCT116 (86.29% ± 4.3 and 91.23% ± 0.52) cell lines. Consistently, the treatment of HT29 cells with 100 μg/mL of Cannellino and Piattellino BFs reduced clonogenicity by 95% ± 2.14 and 96% ± 0.49, respectively. Moreover, the activity of extracts appeared to be selective for colon cancer cells. The data shown in this work further confirm P. vulgaris to be among foods with beneficial effects for human health.
