Brazil Nut-Enriched Diet Modulates Enteric Glial Cells and Gut Microbiota in an Experimental Model of Chronic Kidney Disease. JOURNAL OF THE AMERICAN NUTRITION ASSOCIATION 2024; 43:201-212. [PMID: 37611162 DOI: 10.1080/27697061.2023.2247057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 08/05/2023] [Accepted: 08/08/2023] [Indexed: 08/25/2023]
Abstract
Introduction: Chronic kidney disease (CKD) promotes gut dysbiosis, and enteric glial reactivity, a feature of intestinal inflammation. Brazil nut modulated enteric glial profile in healthy animals and could modulate these cells in 5/6 nephrectomized rats.Methods: A 5/6 nephrectomy-induced CKD and Sham-operated rats were divided as follows: CKD and Sham received a standard diet and CKD-BN and Sham-BN received a 5% Brazil nut enriched-diet. The protein content of glial fibrillary acid protein (GFAP), enteric glial marker, and GPx protein content and activity were assessed in the colon. The major phyla of gut microbiota were assessed.Results: CKD-BN group presented a decrease in GFAP content (p = 0.0001). The CKD-BN group modulated the abundance of Firmicutes, increasing its proportion compared to the CKD group. The CKD-BN group showed increased GPx activity in the colon (p = 0.0192), despite no significant difference in protein content.Conclusion: Brazil nut-enriched diet consumption decreased enteric glial reactivity and modulated gut microbiota in the CKD experimental model.

Supplementation of diet with Brazil nut modulates body composition, bone parameters, and lipid peroxidation in Wistar rats. J Food Biochem 2022; 46:e14294. [PMID: 35762459 DOI: 10.1111/jfbc.14294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 05/13/2022] [Accepted: 06/06/2022] [Indexed: 11/30/2022]
Abstract
Oxidative stress, adipose tissue, and bone compartments can be disturbed in chronic diseases. Non-pharmacological strategies, such as Brazil nuts (BNs), can improve these parameters. This study evaluated the effects of BN supplementation at different concentrations on body composition, lipid profile, and peroxidation in healthy rats. Male Wistar rats were divided into three groups: control (CT), Brazil nut 5% (BN5), and Brazil nut 10% (BN10) groups. Body composition, brown adipose tissue (BAT), plasma lipid peroxidation, and lipid profile were evaluated in the three groups. The BN5 group showed an improvement in all bone parameters compared with that of the CT group (p < .0001). The BN5 and BN10 groups showed reduced plasma lipid peroxidation compared with that of the CT group (p = .0009), whereas the BN10 group presented lower BAT lipid peroxidation than that of the other groups (p = .01). High-density lipoprotein-cholesterol (HDL-c) levels were higher in the BN5 group than in the CT group (p = .01). Conclusively, the use of BNs in a controlled manner promoted improvement in bone parameters, HDL-c levels, and lipid peroxidation in healthy rats. PRACTICAL APPLICATIONS: Nuts has been included in the diet because of their versatility, acceptance, and easy access. Among them, Brazil nut (BN) is considered one of the major known food sources of selenium as well as a source of fibers, unsaturated fatty acids, and phenolic compounds. Studies have shown that BN supplementation is effective in reducing oxidative stress, inflammation, lipid peroxidation, and selenium deficiency when used as a non-pharmacological strategy in experimental models of chronic diseases and in clinical trials. The present study showed that controlled administration of BN improved bone parameters, high-density lipoprotein-cholesterol levels, and lipid peroxidation in healthy rats. Therefore, BN is a promising non-pharmacological agent for the prevention of the onset of chronic non-communicable diseases.

Public Health Nutr 2021; 24:4878-4887. [PMID: 33353574 PMCID: PMC11076271 DOI: 10.1017/s136898002000467x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 10/16/2020] [Accepted: 11/09/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To examine the association between urban food environment and regular consumption of fruits and vegetables (FV) by older adults from a medium-sized Brazilian city. DESIGN Cross-sectional study based on data related to (1) objective assessment of establishments with predominant sale of unprocessed/minimally processed foods, mixed establishments and establishments with predominant sale of ultra-processed foods; (2) regular consumption of FV (≥ 5 times/week), health and socio-demographic variables of community-dwelling older adults. Tertiles of proximity between food establishments and older adults' residence were calculated. Poisson generalised estimating equations with robust variance, adjusted for individual and contextual variables, were used to estimate the independent association between the proximity of establishments and regular consumption of FV. SETTING Medium-sized Brazilian city. SUBJECTS Representative sample of community-dwelling older adults (n 549). RESULTS Older adults travelled the longest distances to establishments with predominant sale of unprocessed/minimally processed foods. The longer the distance to establishments with predominant sale of unprocessed/minimally processed foods, the lower the prevalence of regular consumption of FV (tertile 2: prevalence ratio (PR) = 0·86; 95 % CI = 0·74, 0·99; tertile 3: PR = 0·84; 95 % CI = 0·72, 0·97). Older adults living larger distance tertiles from establishments with predominant sale of ultra-processed foods, mixed establishments or all categories of establishments had 16 % (PR = 0·84; 95 % CI = 0·73, 0·96), 19 % (PR = 0·81; 95 % CI = 0·71, 0·93) and 19 % (PR = 0·81; 95 % CI = 0·70, 0·94) lower prevalence of regular consumption of FV, respectively. CONCLUSION The food environment is associated with regular consumption of FV among older adults. Longer distances from the residence of older adults to food establishments are independently associated with lower prevalence of regular consumption of FV.

Nutraceuticals and Enteric Glial Cells. Molecules 2021; 26:molecules26123762. [PMID: 34205534 PMCID: PMC8234579 DOI: 10.3390/molecules26123762] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 06/11/2021] [Accepted: 06/15/2021] [Indexed: 12/21/2022] Open
Abstract
Until recently, glia were considered to be a structural support for neurons, however further investigations showed that glial cells are equally as important as neurons. Among many different types of glia, enteric glial cells (EGCs) found in the gastrointestinal tract, have been significantly underestimated, but proved to play an essential role in neuroprotection, immune system modulation and many other functions. They are also said to be remarkably altered in different physiopathological conditions. A nutraceutical is defined as any food substance or part of a food that provides medical or health benefits, including prevention and treatment of the disease. Following the description of these interesting peripheral glial cells and highlighting their role in physiological and pathological changes, this article reviews all the studies on the effects of nutraceuticals as modulators of their functions. Currently there are only a few studies available concerning the effects of nutraceuticals on EGCs. Most of them evaluated molecules with antioxidant properties in systemic conditions, whereas only a few studies have been performed using models of gastrointestinal disorders. Despite the scarcity of studies on the topic, all agree that nutraceuticals have the potential to be an interesting alternative in the prevention and/or treatment of enteric gliopathies (of systemic or local etiology) and their associated gastrointestinal conditions.

Development and Application of Healthiness Indicators for Commercial Establishments That Sell Foods for Immediate Consumption. Foods 2021; 10:foods10061434. [PMID: 34205645 PMCID: PMC8235135 DOI: 10.3390/foods10061434] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 06/14/2021] [Accepted: 06/16/2021] [Indexed: 12/21/2022] Open
Abstract
Studies of food environments lack easy-to-apply indicators for their characterization and monitoring. This study aimed to create and assess the applicability of an a priori classification of establishments that sell foods for immediate consumption and to develop and apply indicators for assessment of the establishments’ healthiness. The indicators were grouped by the types of foods sold most frequently at these establishments, according to the extent and purpose of the foods’ industrial processing. Four indicators were developed, based on the availability of unprocessed/minimally processed foods (MPF) and ultra-processed foods (UPF) in the establishments. The classification and indicators were applied to commercial food establishments at two Brazilian universities. Descriptive analyses were performed to characterize the food environment for all the establishments and by university. Two proportion indicators assess the relative availability of subgroups of MPF and UPF. The UPF/MPF ratio expresses the relative advantage/disadvantage of the availability of MPF compared to that of UPF. The Healthiness Index or summary score expresses the availability of MPF and the unavailability of UPF. The classification and indicators present good discriminatory power and are easy to operationalize, interpret, and adapt.
