Abstract
The prevalence of diabetes mellitus is one of the major medical problems that the modern world is currently facing. Type 1 and Type 2 diabetes mellitus both result in early disability and death, as well as serious social and financial problems. In some cases, synthetic drugs can be quite effective in the treatment of diabetes, though they have side effects. Plant-derived pharmacological substances are of particular interest. This review aims to study the antidiabetic properties of secondary plant metabolites. Existing review and research articles on the investigation of the antidiabetic properties of secondary plant metabolites, the methods of their isolation, and their use in diabetes mellitus, as well as separate articles that confirm the relevance of the topic and expand the understanding of the properties and mechanisms of action of plant metabolites, were analyzed for this review. The structure and properties of plants used for the treatment of diabetes mellitus, including plant antioxidants, polysaccharides, alkaloids, and insulin-like plant substances, as well as their antidiabetic properties and mechanisms for lowering blood sugar, are presented. The main advantages and disadvantages of using phytocomponents to treat diabetes are outlined. The types of complications of diabetes mellitus and the effects of medicinal plants and their phytocomponents on them are described. The effects of phytopreparations used to treat diabetes mellitus on the human gut microbiota are discussed. Plants with a general tonic effect, plants containing insulin-like substances, plants-purifiers, and plants rich in vitamins, organic acids, etc. have been shown to play an important role in the treatment of type 2 diabetes mellitus and the prevention of its complications.

Raghavan G, Bapna A, Mehta A, Shah A, Vyas T. Effect of Sugar Replacement with Stevia-Based Tabletop Sweetener on Weight and Cardiometabolic Health among Indian Adults. Nutrients 2023; 15:nu15071744. [PMID: 37049584 PMCID: PMC10097272 DOI: 10.3390/nu15071744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 03/25/2023] [Accepted: 03/28/2023] [Indexed: 04/05/2023] Open
Abstract
Added sugars contribute to caloric intake in the diet, which may lead to conditions like obesity. Replacing added sugar with a natural sugar substitute like zero-calorie stevia may help in reducing sugar and caloric intake. Methods: An open-label, single-arm pilot study was conducted to evaluate the efficacy and safety of a stevia-based tabletop sweetener among overweight subjects with normal blood sugar levels (n = 24) and overweight prediabetic subjects (n = 21). Subjects were instructed to replace added sugar in their daily diet with the test product over a study period of 90 days. Primary outcomes included change in body weight and waist circumference, while the secondary outcomes included change in blood glucose (PPBG), body mass index (BMI), and lipid parameters evaluated at baseline, 30 days, 60 days, and 90 days. Glycated hemoglobin (HbA1c) was evaluated at baseline and 90 days. Results: When compared with the baseline, a significant reduction in weight (p < 0.001) and waist circumference (p < 0.001) was observed at Day 90 in overweight subjects. Similarly, in overweight prediabetic subjects, a significant reduction in weight (p < 0.001) and waist circumference (p < 0.05) with non-significant change in HbA1c was observed at Day 90 from baseline. In a subgroup analysis, among the subjects who lost weight, 2.12 kg (n = 35) weight loss and 4.78 cm (n = 32) reduction in waist circumference were observed at 90 days. No adverse outcomes were reported throughout the study period. The consumption of steviol glycosides was within the acceptable daily intake (ADI). Conclusions: Replacing added sugar in the daily diet with stevia-based tabletop sweetener, along with a physical activity regimen, promotes weight loss and reduction in waist circumference in overweight subjects with normal blood sugar levels and prediabetic subjects (CTRI/2019/12/022470).

Abstract
The effect of stevioside on human health is still insufficiently highlighted by recent research. The total or partial replacement of sugar with sweeteners influences the general state of health, especially the human microbiota's response as a determining factor in the onset of type 2 diabetes. The present study aimed to present the long-term (one-year) in vitro effect that regular stevioside consumption had on children's pattern microbiota. A metabolomic response was established by determining the synthesis of organic acids and a correlation with antioxidant status. An increase in the number of bacterial strains and the variation of amount of butyrate and propionate to the detriment of lactic acid was observed. The effect was evidenced by the progressive pH increasing, the reduction of acetic acid, and the proliferation of Escherichia coli strains during the simulations. Synthesis of the main short-chain fatty acids (SCFAs) was interpreted as a response (adaptation) of the microbiota to the stevioside, without a corresponding increase in antioxidant status. This study demonstrated the modulatory role of stevioside on the human microbiota and on the fermentation processes that determine the essential SCFA synthesis in maintaining homeostasis. The protection of the microbiota against oxidative stress was also an essential aspect of reducing microbial diversity.

Rashad NM, Sayed SE, Sherif MH, Sitohy MZ. Effect of a 24-week weight management program on serum leptin level in correlation to anthropometric measures in obese female: A randomized controlled clinical trial. Diabetes Metab Syndr 2019; 13:2230-2235. [PMID: 31235162 DOI: 10.1016/j.dsx.2019.05.027] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Accepted: 05/24/2019] [Indexed: 11/26/2022]
Abstract
BACKGROUND Obesity is a major contributor to preventable disease and death across the globe. Obesity is complex. Although its risk factors are myriad and compounding, there is an urgent need for a deeper understanding of the way risk factors interact with each other. Leptin is a peptide regulates food intake and body weight. However, the notion of leptin as an anti-obesity hormone was called into question because obesity is typically associated with high leptin levels and not leptin deficiency thus, we aimed to measure leptin levels in obese female in correlation to anthropometric measures and to evaluate the impact of weight loss on its level and metabolic parameters. SUBJECT AND METHODS case-control study enrolled 40 control groups, 50 obese women. We measured anthropometric measures BMI, Waist/hip ratio (WHR). Fat mass index (FMI%) and free fat mass index (FFMI%) were assessed by dual energy X-Ray absorptiometry (DEXA) The serum levels of leptin were measured by ELISA. RESULTS Our results revealed that serum leptin levels were higher in obese women compared to controls. Moreover, it was positively correlated to anthropometric measures, glycemic and lipid profile. Linear regression analysis revealed that BMI was the main independent studied parameters associated with serum leptin level among other clinical and laboratory biomarkers. Interestingly, after 12 weeks of following the Mediterranean diet (MD)-based weight loss program, serum leptin levels were decreased. Logistic regression analysis was performed to detect the main predictors' biomarkers associated with weight loss among obese women. We found that serum leptin and FMI% were an independent predictor of response with odds ratios of 1.69 and 1.64 respectively (P < 0.001), Receiver operating characteristic analyses revealed that the AUC of serum leptin in discriminating obese women from lean ones was 0.893 (95% CI = 0.815-0.917) with sensitivity = 90%, specificity = 96%, and the cutoff values was 36.32 ng/ml. CONCLUSION Serum leptin could be a valuable diagnostic marker of obesity and its comorbidities. Moreover, significant weight loss leads to decrease serum leptin levels and improvement of glycemic and lipid profiles.
