Santamarina AB, Calder PC, Estadella D, Pisani LP. Anthocyanins ameliorate obesity-associated metainflammation: Preclinical and clinical evidence. Nutr Res 2023; 114:50-70. [PMID: 37201432 DOI: 10.1016/j.nutres.2023.04.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 03/13/2023] [Accepted: 04/10/2023] [Indexed: 05/20/2023]
Abstract
The growing rates of obesity worldwide call for intervention strategies to help control the pathophysiological consequences of weight gain. The use of natural foods and bioactive compounds has been suggested as such a strategy because of their recognized antioxidant and anti-inflammatory properties. For example, polyphenols, especially anthocyanins, are candidates for managing obesity and its related metabolic disorders. Obesity is well known for the presence of metainflammation, which has been labeled as an inflammatory activation that leads to a variety of metabolic disorders, usually related to increased oxidative stress. Considering this, anthocyanins may be promising natural compounds able to modulate several intracellular mechanisms, mitigating oxidative stress and metainflammation. A wide variety of foods and extracts rich in anthocyanins have become the focus of research in the field of obesity. Here, we bring together the current knowledge regarding the use of anthocyanins as an intervention tested in vitro, in vivo, and in clinical trials to modulate metainflammation. Most recent research applies a wide variety of extracts and natural sources of anthocyanins, in diverse experimental models, which represents a limitation of the research field. However, the literature is sufficiently consistent to establish that the in-depth molecular analysis of gut microbiota, insulin signaling, TLR4-triggered inflammation, and oxidative stress pathways reveals their modulation by anthocyanins. These targets are interconnected at the cellular level and interact with one another, leading to obesity-associated metainflammation. Thus, the positive findings with anthocyanins observed in preclinical models might directly relate to the positive outcomes in clinical studies. In summary and based on the entirety of the relevant literature, anthocyanins can mitigate obesity-related perturbations in gut microbiota, insulin resistance, oxidative stress and inflammation and therefore may contribute as a therapeutic tool in people living with obesity.

Abstract
BACKGROUND AND AIMS Juçara is a fruit of ecological and nutritional importance. Its fruits represent an option for the sustainable use of the plant due to its vulnerability to extinction. Thus, the aim of this review was to analyze clinical and experimental studies and highlight the literature gaps regarding the effects of supplementation with Juçara on health. METHODS For this scoping review, we consulted the Medline (PubMed), Science Direct, and Scopus databases in March, April, and May 2022. Experimental studies and clinical trials published in the last ten years (2012-2022) were analyzed. Data were synthesized and reported. RESULTS A total of 27 studies were included, 18 of which were experimental studies. Of these, 33% evaluated inflammatory markers associated with fat accumulation. Most of these studies (83%) used pulp in lyophilized form, and the others (17%) involved juçara extract mixed in water. In addition, 78% of the studies showed positive results with respect to the lipid profile, reduction of oncological lesions, inflammation, microbiota modulation, and improvement in obesity and glycemia-related metabolic complications. Nine clinical trials with results similar to those of experimental trials were found. The majority (56%) were chronic (four to six weeks into the intervention), and 44% were acute. Three offered juçara supplementation in the form of juice, four used freeze-dried pulp, two used fresh pulp, and one used a 9% dilution. The dose was fixed at 5 g, but the dilution ranged from 200 to 450 mL. These trials assessed mainly healthy, physically active, and obese individual adults (19-56 years old), and cardioprotective and anti-inflammatory effects, as well as improvement in the lipid profile and prebiotic potential, were observed. CONCLUSION Juçara supplementation showed promising results with respect to its effect on health. However, further studies are needed to clarify these possible effects on health and their mechanisms of action.

Abstract
Juçara (Euterpe edulis Martius) is a palm widely distributed in the Atlantic Forest. It produces a non-climacteric, black-violet small fruit similar to the Amazonian açaí (Euterpe precatoria). The fruit is known as superfruit because it presents chemical characteristics of great importance, such as anthocyanins content. Regarding bioactive compounds and antioxidant scavenging capacity, it presents high anthocyanin (634.26 to 2,929 mg of cyanidin-3-glucoside 100 g-1) and total phenolic compounds (415.1 to 9,778.20 mg equivalents of gallic acid 100 g-1) contents. The soluble solid content ranges from 3.0 to 4.9% and its pH is higher than other tropical fruits (4.8 to 5.6). Despite the rich bioactive compound content of juçara fruits, this plant has been traditionally used for palm heart production. The accelerated and illegal palm heart exploitation, without the use of an adequate management has led to the risk of extinction of this species. In order to prevent this species from vanishing, several studies have valued the health characteristics of juçara fruit chemical composition. An economical approach has been the production of juçara pulp described as a source of bioactive compounds, which has attracted the attention of industrial field aiming the production of functional foods, foodstuff, cosmetics and pharmaceutical products. A full botanical and chemical characterization of juçara tree and fruit is presented in this paper, as well as suggestions to increase the use of this tropical fruit and derivatives.

Nutritional Composition and Bioactive Compounds of Native Brazilian Fruits of the Arecaceae Family and Its Potential Applications for Health Promotion. Nutrients 2022; 14:nu14194009. [PMID: 36235663 PMCID: PMC9571529 DOI: 10.3390/nu14194009] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 09/21/2022] [Accepted: 09/22/2022] [Indexed: 11/25/2022] Open
Abstract
The fruits from the Arecaceae family, although being rich in bioactive compounds with potential benefits to health, have been underexplored. Studies on their composition, bioactive compounds, and effects of their consumption on health are also scarce. This review presents the composition of macro- and micronutrients, and bioactive compounds of fruits of the Arecaceae family such as bacaba, patawa, juçara, açaí, buriti, buritirana, and butiá. The potential use and reported effects of its consumption on health are also presented. The knowledge of these underutilized fruits is important to encourage production, commercialization, processing, and consumption. It can also stimulate their full use and improve the economy and social condition of the population where these fruits are found. Furthermore, it may help in future research on the composition, health effects, and new product development. Arecaceae fruits presented in this review are currently used as raw materials for producing beverages, candies, jams, popsicles, ice creams, energy drinks, and edible oils. The reported studies show that they are rich in phenolic compounds, carotenoids, anthocyanins, tocopherols, minerals, vitamins, amino acids, and fatty acids. Moreover, the consumption of these compounds has been associated with anti-inflammatory, antiproliferative, antiobesity, and cardioprotective effects. These fruits have potential to be used in food, pharmaceutical, and cosmetic industries. Despite their potential, some of them, such as buritirana and butiá, have been little explored and limited research has been conducted on their composition, biological effects, and applications. Therefore, more detailed investigations on the composition and mechanism of action based on in vitro and/or in vivo studies are needed for fruits from the Arecaceae family.

Abstract
Fat browning has piqued the interest of researchers as a potential target for treating obesity and related metabolic disorders. Recruitment of brown adipocytes leads to enhanced energy dissipation and reduced adiposity, thus facilitating the maintenance of metabolic homeostasis. Evidence is increasing to support the crucial roles of polyphenols and gut microecology in turning fat "brown". However, it is not clear whether the intestinal microecology is involved in polyphenol-mediated regulation of adipose browning, so this concept is worthy of exploration. In this review, we summarize the current knowledge, mostly from studies with murine models, supporting the concept that the effects of food phenolics on brown fat activation and white fat browning can be attributed to their regulatory actions on gut microecology, including microbial community profile, gut metabolites, and gut-derived hormones. Furthermore, the potential underlying pathways involved are also discussed. Basically, understanding gut microecology paves the way to determine the underlying roles and mechanisms of food phenolics in adipose browning.

Chemical composition, bioactive compounds extraction, and observed biological activities from jussara (Euterpe edulis): The exotic and endangered Brazilian superfruit. Compr Rev Food Sci Food Saf 2021; 20:3192-3224.

Abstract
In this article, we reviewed studies on the fruits of the jussara palm (Euterpe edulis Martius), an endangered Brazilian Atlantic Forest palm tree, also coined as "Superfruit." We summarized the chemical components of the pulp and observed biological activities in murine and humans, as well as the best practices involving the extraction of its target compounds, bioavailability, and stability of extracts. Jussara has shown a rich phenolic profile that justifies its antioxidant properties, in addition to a considerable lipidic and energetic value. As the main feature, the fruit possesses large amounts of anthocyanins that can be commercially explored as a food additive or cosmetic colorants. Recent studies emphasized jussara's antioxidant, anti-inflammatory, and cardioprotective capabilities via reshaping of the gut microbiota. Further knowledge is needed to establish bioavailability and optimal serving size, as many of its antioxidant compounds go under chemical bioconversion in the intestinal tract. While extraction of phenolic compounds, anthocyanins, and oils have interesting results, more studies are required in order to reduce the use of conventional organic solvents and improve their stability and shelf life when added to food products, an area in which nanotechnology seems promising.

Abstract
Adipose tissue inflammation has been proposed as a central mechanism connecting obesity with its metabolic and vascular complications due to the imbalance in the expression of several hormones and adipokines. Berries rich in polyphenols and unsaturated fatty acids have been able to prevent both obesity and adipose tissue inflammation, improving metabolic functions in human subjects and animal models of obesity. Juçara has been considered a super fruit owing to its nutritional composition and relevant biological activities with an interesting response in animals. Thus, we aimed to verify the potential antiobesogenic effect of juçara supplementation in humans. We conducted a double-blind, placebo-controlled, randomized trial with 35 adults with obesity of both sexes. They were assessed for resting metabolic rate, anthropometry and body composition, blood pressure, metabolic parameters and adipokines. Subsequently, they were randomized into two groups to use or not (placebo) 5 g lyophilized juçara for 6 weeks. Supplementation with juçara was significantly effective in reducing body fat, increasing high-density lipoprotein cholesterol and doubling serum adiponectin. Besides, juçara supplementation, high-density lipoprotein cholesterol and neck circumference were predictors to explain the enhancement in adiponectin. Juçara supplementation was determinant to improve adiponectin levels, and it may be considered a novel strategy for the treatment of obesity-related metabolic diseases.

Abstract
Brown adipose tissue (BAT) has recently been given more attention for the part it plays in obesity. BAT can generate great amounts of heat through thermogenesis by the activation of uncoupling protein 1 (UCP-1), which can be regulated by many environmental factors such as diet. Moreover, the build-up of BAT relates to maternal nutritional changes during pregnancy and lactation. However, at present, there is a limited number of studies looking at maternal nutrition and BAT development, and it seems that the research trend in this field has been considerably declining since the 1980s. There is much to discover yet about the role of different fatty acids on the development of BAT and the activation of UCP-1 during the fetal and the postnatal periods of life. A better understanding of the impact of nutritional intervention on the epigenetic regulation of BAT could lead to new preventive care for metabolic diseases such as obesity. It is important to know in which circumstances lipids could programme BAT during pregnancy and lactation. The modification of maternal dietary fatty acids, amount and composition, during pregnancy and lactation might be a promising strategy for the prevention of obesity in the offspring and future generations.

Abstract
PURPOSE Obesity is an inflammatory-related disease, which recruits immune system cells triggering to imbalanced production of cytokines. Obesity management and treatment using foods bioactive compounds have gained clinical and scientific relevance. Juçara (Euterpe edulis Mart.) fruit is rich in fibers, unsaturated lipids and, anthocyanins showing potential health benefits. Thus, we investigated the effect of juçara pulp intake on inflammatory status of monocytes from obese individuals. METHODS It is a placebo-controlled, randomized double-blind trial. Twenty-seven obese participants (BMI between 30.0 and 39.9 kg/m2) of both genders from 31 to 59-year-old, divided into two groups: 5 g juçara freeze-dried pulp or 5 g of placebo for 6 weeks. Before and after supplementation, blood samples were collected and monocytes obtained and stimulated with lipopolysaccharides. After 24 h of incubation, the cells and supernatants were analyzed. RESULTS Post-treatment, juçara reduced TLR4, and IL-6 mRNA compared to placebo. Juçara also increased IL-10 mRNA in post-treatment. The protein expression of TLR4 pathway post-treatment, MYD88 expression reduced in juçara group compared to placebo. The juçara post-treatment reduced pIKKα/β compared to the placebo. Ob-R protein levels were higher in the juçara group post-treatment compared to pre-treatment. IL-6, TNF-α, and MCP-1 production by monocytes were reduced by juçara in post-treatment compared to pre-treatment levels. The supplementation increased IL-10 in juçara group with LPS compared to pre-treatment and versus juçara group without LPS. CONCLUSION These results demonstrated a proinflammatory state at the beginning, which was improved by juçara pulp consumption. Our results suggest juçara pulp as a potential tool against the proinflammatory status of obesity.

Abstract
Obesity is associated with modern diets that are rich in saturated fatty acids. These dietary patterns are linked to low-grade proinflammatory mechanisms, such as the toll-like receptor 4/nuclear factor kappa-B (NF-κB) pathway rapidly activated through high-fat diets. Juçara is a berry rich in anthocyanins and unsaturated fatty acids, which prevents obesity and associated comorbidities. We evaluated the effect of different doses of freeze-dried juçara pulp on NF-κB pathway after the consumption of short-term high-fat diet. Male Wistar rats with ad libitum access to food and water were divided into four groups: Control diet (C), high-fat diet (HFC), high-fat diet with 0.25% juçara (HFJ 0.25%), and high-fat diet with 0.5% juçara (HFJ 0.5%). Energy intake and body weight gain were increased in HFC and HFJ 0.5% groups compared to C group. The hypothalamus weight reduced in the HFC group compared to C and HFJ 0.25% groups. Cytokines, MYD88, TRAF6, and pNF-κBp50 levels in the hypothalamus, serum triacylglycerol, LDL-cholesterol (LDL-C), and free fatty acid levels were improved in the HFJ 0.25% group. In summary, the HFJ 0.25% group had better protective effects than those in the HFJ 0.5%. Therefore, 0.25% juçara can be used to protect against central inflammation through the high-fat diet-induced NF-κB pathway.
