Carob Extract ( Ceratonia siliqua L.): Effects on Dyslipidemia and Obesity in a High-Fat Diet-Fed Rat Model. Pharmaceutics 2023; 15:2611. [PMID: 38004588 PMCID: PMC10674595 DOI: 10.3390/pharmaceutics15112611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 10/25/2023] [Accepted: 11/06/2023] [Indexed: 11/26/2023] Open
Abstract
Dyslipidemia and obesity are recognized as two of the major global health issues and main risk factors for coronary heart disease and cerebrovascular disease. In recent years, carob has shown certain antioxidant and anti-dyslipidemic potential. In this study, Wistar rats were fed with a standard and cholesterol-enriched diet and treated orally with carob extract and simvastatin for four weeks. After sacrifice, blood samples were collected for biochemical analysis, and liver tissue was taken for histological and immunohistochemical assessment. Weight gain was significantly higher in groups fed with cholesterol-fortified granules; total cholesterol was found to be significantly lower in the hypercholesterolemic groups treated with simvastatin and simvastatin/carob combined regimens compared with hypercholesterolemic animals treated with saline (p < 0.05). The same was true for low-density lipoprotein cholesterol and the LDL/HDL ratio (p < 0.05). Adiponectin was remarkably higher in animals treated with simvastatin compared to all other groups (p < 0.05). Leptin was significantly lower in groups treated with carob and simvastatin compared to the hypercholesterolemic group treated with saline (p < 0.05). Carob/simvastatin co-administration reduced hepatocyte damage and improved liver morphology. A study confirmed the anti-dyslipidemic, anti-obesity, and hepatoprotective potential of carob pulp alone or in combination with simvastatin in the treatment of high-fat diet-fed rats.

Carob Extract Supplementation Together with Caloric Restriction and Aerobic Training Accelerates the Recovery of Cardiometabolic Health in Mice with Metabolic Syndrome. Antioxidants (Basel) 2022; 11:antiox11091803. [PMID: 36139877 PMCID: PMC9495762 DOI: 10.3390/antiox11091803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 09/08/2022] [Accepted: 09/09/2022] [Indexed: 11/16/2022] Open
Abstract
Carob, the fruit of Ceratonia siliqua L. exerts antidiabetic, anti-inflammatory, and antioxidant effects and could be a useful strategy for the treatment and/or prevention of metabolic syndrome (MetS). The aim of this study was to analyze whether supplementation with a carob fruit extract (CSAT+®), alone or in combination with aerobic training, accelerates the recovery of cardiometabolic health in mice with MetS subjected to a caloric restriction. For this purpose, mice were fed with a high fat (58% kcal from fat)/high sugar diet for 23 weeks to induce MetS. During the next two weeks, mice with MetS were switched to a diet with a lower caloric content (25% kcal from fat) supplemented or not with CSAT+® (4.8%) and/or subjected to aerobic training. Both caloric reduction and aerobic training improved the lipid profile and attenuated MetS-induced insulin resistance measured as HOMA-IR. However, only supplementation with CSAT+® enhanced body weight loss, increased the circulating levels of adiponectin, and lowered the plasma levels of IL-6. Moreover, CSAT+® supplementation was the only effective strategy to reduce the weight of epidydimal adipose tissue and to improve insulin sensitivity in the liver and in skeletal muscle. Although all interventions improved endothelial function in aorta segments, only supplementation with CSAT+® reduced obesity-induced hypertension, prevented endothelial dysfunction in mesenteric arteries, and decreased the vascular response of aorta segments to the vasoconstrictor AngII. The beneficial cardiometabolic effects of CSAT+® supplementation, alone or in combination with aerobic training, were associated with decreased mRNA levels of pro-inflammatory markers such as MCP-1, TNFα, IL-1β, and IL-6 and with increased gene expression of antioxidant enzymes, such as GSR, GPX-3, and SOD-1 in the liver, gastrocnemius, retroperitoneal adipose tissue, and aorta. In conclusion, supplementation with CSAT+®, alone or in combination with aerobic training, to mice with MetS subjected to caloric restriction for two weeks enhances body weight loss, improves the lipid profile and insulin sensitivity, and exerts antihypertensive effects through its anti-inflammatory and antioxidant properties.
