Soybeans display strategic potential in food security as a source of protein and functional bioactives for human consumption. Polyphenols and other bioactive compounds can be recovered after an aqueous extraction from soybean meal, a byproduct of soy oil refining. The objective of the present study was to compile and quantify compounds from soybean oil refinery by-products, providing information about valuable bioactive phytochemicals, their bioaccessibility and potential bioactivities. Genistin, daidzin, glycitin and malonylgenistin were the predominant isoflavones, and the overall bioaccessibility of their glycosidic forms was of nearly 75%. Sixteen phenolics were identified and caffeic acid, 5-caffeoylquinic chlorogenic acid and hesperidin were the most predominant. Approximately 30% of gallic acid, syringic acid, vanillic acid and myricetin were released and the antioxidant capacity of aqueous extract was enhanced after simulated in vitro gastro intestinal digestion. The ability of aqueous soybean meal extract to inhibit lipid peroxidation was higher than natural and synthetic food antioxidants. Antimicrobial activity against several foodborne pathogens and antitumoral activity towards human glioblastoma cell line were also observed, but the aqueous extract showed no cytotoxicity to healthy murine cells. Compounds derived from the aqueous soybean meal extract have the potential to be used as health promoting agents.

Introduction: Food choice is influenced by several factors, including intrinsic and extrinsic food characteristics. Nutritional food properties, and, the health benefits provided by these, may affect this choice.Objective: The aim of this study was to evaluate the influence of health allegations on food choices of adults explicitly and implicitly, by adapting the Implicit Association methodology. Method:The sample consisted in 108 individuals. For explicit assessment, the sensory acceptability analysis test was conducted in two sessions (blind and with information), to evaluate the influence of non-sensory characteristics. For implicit assessment, an implicit test was performed, using FreeIAT software. To evaluate nutritional status, weight, height, and waist circumference were measured and Body Mass Index calculated. To analyze the results, descriptive statistics were performed to observe the frequency, the mean ± standard deviation. In, addition, the t-test and Spearman correlation test were performed, adopting a 5% significance level. Results:In the explicit evaluation, it was observed that information about health benefits positively influenced food choice (p<0.01). When assessing healthy food information implicitly, it was clear that 43,52% of participants had a strong preference for healthy foods. Conclusion:The results showed that knowledge about the nutritional aspects of food interferes with food choices explicitly and implicitly. Also, the FreeIAT program proved to be an excellent complementary tool for studies, with consumers regarding food choices, being an innovation for researches in this segment.

“…Phytoestrogens can bring many other health benefits besides the decreased risks of hormone-related cancers [ 138 ]. These include the prevention of vascular diseases through the inhibition of in vitro oxidation of the low-density lipoprotein involved in the pathogenesis of atherosclerosis [ 139 ], hypercolesteremia [ 140 ], osteoporosis [ 141 ] and menopausal symptoms [ 142 ].…”

Throughout evolution, plants have developed the ability to produce secondary phenolic metabolites, which are important for their interactions with the environment, reproductive strategies and defense mechanisms. These (poly)phenolic compounds are a heterogeneous group of natural antioxidants found in vegetables, cereals and leguminous that exert beneficial and protective actions on human health, playing roles such as enzymatic reaction inhibitors and cofactors, toxic chemicals scavengers and biochemical reaction substrates, increasing the absorption of essential nutrients and selectively inhibiting deleterious intestinal bacteria. Polyphenols present in some commodity grains, such as soy and cocoa beans, as well as in other vegetables considered security foods for developing countries, including cassava, taro and beetroot, all of them cropped in Brazil, have been identified and quantified in order to point out their bioavailability and the adequate dietary intake to promote health. The effects of the flavonoid and non-flavonoid compounds present in these vegetables, their metabolism and their effects on preventing chronic and degenerative disorders like cancers, diabetes, osteoporosis, cardiovascular and neurological diseases are herein discussed based on recent epidemiological studies.
