Elevated LDL-c may warn of the risk of gallbladder stones in the patients with metabolic dysfunction-associated steatotic liver disease: A case-control study. Clin Res Hepatol Gastroenterol 2024; 48:102363. [PMID: 38703815 DOI: 10.1016/j.clinre.2024.102363] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 04/12/2024] [Accepted: 05/01/2024] [Indexed: 05/06/2024]
Abstract
PURPOSE This study aimed to explore the relationship between metabolic dysfunction-associated steatotic liver disease (MASLD) and the development of new-onset gallbladder stone disease (GSD) and to identify factors that influence the occurrence of new-onset GSD in patients with MASLD. METHODS In this retrospective case-control study, patients who underwent asymptomatic GSD screening during annual routine health check-ups at two hospitals in China between August 2017 and July 2022 were included. Patients with new-onset GSD and controls without GSD were matched 1:1 based on age, sex, race, occupation, diet, drinking habits, systolic blood pressure, diastolic blood pressure, and fasting blood glucose levels. RESULTS The study comprised 1200 patients with new-onset GSD and 1200 controls without GSD. Patients with new-onset GSD had higher rates of MASLD (33.8% vs. 22.2 %, P < 0.001) and hypercholesterolemia (12.6% vs. 7.2 %, P < 0.001) compared to controls. Waist circumference (WC) (OR = 1.042, 95 % CI: 1.022-1.063, P < 0.001), high-density lipoprotein cholesterol (HDL-c) (OR = 0.048, 95 % CI: 0.037-0.062, P < 0.001), triglycerides (OR = 0.819, 95 % CI: 0.699-0.958, P = 0.013), and hypercholesterolemia (OR = 5.023, 95 % CI: 2.735-9.225, P < 0.001) were independently associated with new-onset GSD. Among patients with MASLD, WC (OR = 1.075, 95 % CI: 1.026-1.127, P = 0.003), total cholesterol (TC) (OR = 2.094, 95 % CI: 1.259-3.484, P = 0.004), HDL-c (OR = 0.088, 95 % CI: 0.054-0.142, P < 0.001), and low-density lipoprotein cholesterol (LDL-c) (OR = 4.056, 95 % CI: 2.669-6.163, P < 0.001) were independently associated with new-onset GSD. CONCLUSIONS The findings indicate that hypercholesterolemia is independently associated with GSD. Among patients with MASLD, hypercholesterolemia also showed an independent association with GSD. Notably, this study is the first to identify serum LDL-c levels as potentially the most significant risk factor for GSD, highlighting that elevated LDL-c could serve as an important indicator for individuals with MASLD.

Bahari H, Taheri S, Namkhah Z, Barghchi H, Arzhang P, Nattagh-Eshtivani E. Effects of sumac supplementation on lipid profile: A systematic review and meta-analysis of randomized controlled trials. Phytother Res 2024; 38:241-252. [PMID: 37864474 DOI: 10.1002/ptr.8046] [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: 03/28/2023] [Revised: 09/25/2023] [Accepted: 09/29/2023] [Indexed: 10/22/2023]
Abstract
This systematic review aimed to gather data on the effects of sumac supplementation on lipid profile. A systematic literature search was carried out using electronic databases (PubMed, Scopus, and Web of Science) up to March 2023 to identify eligible randomized controlled trials (RCTs) assessing the effects of sumac intake on lipid profile as an outcome. All participants enrolled in our study were adult individuals who consumed sumac, in various forms, as an intervention. The included articles were assessed using the Cochrane risk of bias assessment tool. Heterogeneity tests of the selected trials were performed using the I2 statistic. Random effects models were assessed based on the heterogeneity tests, and pooled data were determined as the weighted mean difference with a 95% confidence interval. In total, seven RCTs with a total sample size of 570 subjects were included. This study found a significant decrease in total cholesterol (TC) (weighted mean difference [WMD]: -10.01 mg/dL; 95% CI: -18.67, -1.34), triglyceride (TG) (WMD: -8.52 mg/dL; 95% CI: -14.79, -2.25), and low-density lipoprotein (LDL)-C levels (WMD: -9.25 mg/dL; 95% CI: -14.56, -3.93); Moreover, a significant increase was observed in high-density lipoprotein (HDL)-C concentration (WMD: 2.97 mg/dL; 95% CI: 0.75, 5.19). The reduction in TG and TC was greater in studies with a duration of ≥12 compared to <12 weeks. The increase in HDL-C was greater in participants with an intervention duration of ≥12 compared to <12 weeks. Moreover, subgroup analysis based on the dose of sumac suggested a significant reduction in TC and LDL, specifically for doses below 3 g. Consumption of sumac significantly decreased serum TC, LDL-C, and TG concentrations. This study suggested significantly positive effects on HDL-C by intake of sumac. Longer interventions (>12 weeks) have a more favorable impact on TC, LDL-C, and HDL-C, while sumac doses below 3 g/day show greater effects on TC and LDL-C. These findings underscore the potential of sumac supplementation as a valuable approach to lipid profile management.

Effects of turmeric extract supplementation on the lipid and lipoprotein subfraction profile in hemodialysis patients: A randomised, double-blind, crossover and controlled trial. Phytother Res 2023; 37:3424-3437.

Abstract
Dyslipidemia is common in patients with chronic kidney disease. Curcumin, a bioactive polyphenol from Curcuma longa, can improve lipid profile. This study aims to analyze the effects of Curcuma Longa extract supplementation on lipid profile and lipoprotein subfractions in hemodialysis (HD) patients. This is a longitudinal, double-blind, washout-period randomized clinical trial. The patients were randomized into two groups: the curcumin group (n = 10) (orange and carrot juice with 2.5 g of Curcuma Longa extract) and the control group (n = 11) (juice without curcumin) 3x/w during HD sessions for 3 months. After the washout period, patients continued the supplementation as a crossover for the same period. The lipid profile was measured using enzymatic assays. The high-density lipoprotein and low-density lipoprotein subfractions analyses were performed using LipoprintTM. In the curcumin group, the triglyceride values tended to decrease with a different triglyceride variation between the pre and post-intervention for the control and curcumin groups of 38.5 (19.8) mg/dL (p = 0.06). There was no statistical difference in the others parameters. In conclusion, Curcuma longa extract may be a good nutritional strategy to reduce triglyceride plasma levels in hemodialysis patients, but it seems ineffective for the other parameter.

Abstract
Few studies examined the association of energy, macronutrients and food consumption at dinner v. breakfast with hypercholesterolaemia. A total of 27 911 participants from the National Health and Nutrition Examination Survey (2003-2016) were included in the cross-sectional study. Energy, macronutrients and food consumption at breakfast, dinner and the difference at dinner v. breakfast (Δratio) were calculated. Multiple logistic regression models and substitution effects of foods at dinner with breakfast were also performed. After adjustment for potential covariates, compared with the lowest quintile, participants in the highest quintile of Δratio in terms of energy had a higher risk of prevalent hypercholesterolaemia (ORΔratio of energy 1·16, 95 % CI (1·01, 1·33)) mainly due to Δratio of low-quality carbohydrates and plant protein (ORΔratio of low-quality carbohydrates 1·19; 95 % CI (1·05, 1·35)); ORΔratio of plant protein 1·13; 95 % CI (1·01, 1·28)). ΔAdded sugars and Δnuts were associated with hypercholesterolaemia (ORΔadded sugars 1·01; 95 % CI (1·00, 1·02)); ORΔnuts 1·08; 95 % CI (1·01, 1·16)). Furthermore, the substitution of added sugars, nuts and processed meat at dinner with breakfast could reduce the OR of hypercholesterolaemia. This study indicated that among US adults, overconsumption of energy, macronutrients including low-quality carbohydrates and plant protein at dinner than breakfast was significantly associated with a higher risk of prevalent hypercholesterolaemia. The replacing of added sugar, nuts and processed meat at dinner with breakfast reduced the risk of prevalent hypercholesterolaemia. This study emphasised the importance of meal timing in the prevention of hypercholesterolaemia.

Abstract
Essential oils (EOs) are complex secondary metabolites identified in many plant species. Plant-derived EOs have been widely used in traditional medicine for centuries for their health-beneficial effects. Some EOs and their active ingredients have been reported to improve the cardiovascular system, in particular to provide an anti-atherosclerotic effect. The objective of this review is to highlight the recent research investigating the anti-inflammatory, anti-oxidative and lipid-lowering properties of plant-derived EOs and discuss their mechanisms of action. Also, recent clinical trials exploring anti-inflammatory and anti-oxidative activities of EOs are discussed. Future research on EOs has the potential to identify new bioactive compounds and invent new effective agents for treatment of atherosclerosis and related diseases such as diabetes, metabolic syndrome and obesity.

Abstract
This systematic review and meta-analysis were conducted to evaluate the impact of bergamot (KoksalGarry) and its nutraceutical compounds on lipid profiles. PubMed, Web of Knowledge, Scopus, and Google Scholar searched for relevant articles. Trials investigating the effect of oral bergamot supplementation on serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in adults were included. The mean differences and standard deviations were pooled using a random-effects model. Fourteen trials were included in this systematic review and meta-analysis. Bergamot supplementation significantly decreased serum levels of TC (weighted mean difference (WMD): -63.60 mg/dL; 95% CI: -78.03 to -49.18; p < .001), TG (WMD: -74.72 mg/dL; 95% CI: -83.58 to -65.87; p < .001), LDL-C (WMD: -55.43 mg/dL; 95% CI: -67.26 to -43.60; p < .001), and increased HDL-C (WMD: 5.78 mg/dL; 95% CI: 3.27 to 8.28; p < .001), respectively. Our systematic review of the effects of nutraceuticals containing bergamot on lipid markers showed inconsistent results. The results showed that bergamot supplementation might improve lipid profiles. The findings for nutraceutical compounds containing bergamot were inconsistent. However, the clinical efficacy of bergamot on lipid profiles needs to be further established through higher-quality studies.

The effects of phytosterol and phytostanol supplementation on the lipid profile in postmenopausal women: A systematic review and meta-analysis of randomized controlled trials. Phytother Res 2022; 36:4398-4408. [PMID: 36180973 DOI: 10.1002/ptr.7646] [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: 02/03/2022] [Revised: 08/20/2022] [Accepted: 09/18/2022] [Indexed: 02/01/2023]
Abstract
Various studies have proven that phytosterols and phytostanols (PS) are lipid-lowering agents. These compounds play a role in regulating high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and triglyceride (TG) metabolism. Although various drugs are available and are currently used to treat dyslipidemia, the management of lipid abnormalities during the postmenopausal period remains a challenge. Thus, scientists are trying to develop new strategies to reduce serum lipids concentrations using natural products. However, the impact of PS administration on serum lipids in postmenopausal women remains unclear. Hence, the purpose of this study was to assess the effect of PS supplementation on the lipid profile in postmenopausal women based on a systematic review of the literature and a meta-analysis of randomized controlled trials. PubMed/Medline, Scopus, Embase, and Web of Science were searched to identify suitable papers published until January 18, 2022. We combined the effect sizes with the DerSimonian and Laird method using a random effects model. PS supplementation resulted in a significant decrease in TC (weighted mean difference [WMD]: -16.73 mg/dl) and LDL-C (WMD: -10.06 mg/dl) levels. No effect of PS supplementation on TG (WMD: -1.14 mg/dl) or HDL-C (WMD: -0.29 mg/dl) concentrations was detected. In the stratified analysis, there was a notable reduction in TC and LDL-C levels when the PS dose was ≥2 g/day (TC: -22.22 mg/dl and LDL-C: -10.14 mg/dl) and when PS were administered to participants with a body mass index ≥25 kg/m2 (TC: -20.22 mg/dl and LDL-C: -14.85 mg/dl). PS administration can decrease TC and LDL-C, particularly if the dose of administration is ≥2 g/day and if the participants are overweight or obese. Further high-quality studies are needed to firmly establish the clinical efficacy of PS usage in postmenopausal females.

Abstract
OBJECTIVE: This study evaluated the effect of sardine (SPH) and chickpea protein hydrolysates (CPH) on oxidant stress and inflammatory profile in cholesterol-fed rats. METHODS: The experiment was undertaken for thirty days on 18 cholesterol-fed Wistar rats (220±10 g) divided into three groups and receiving 1 g/kg of body weight either chickpea protein hydrolysate (CPH), sardine protein hydrolysate (SPH) or casein in water (CG). RESULTS: Compared to CG, SPH and CPH treatment reduced cholesterol, hydroperoxide and malondialdehyde contents in serum, lipoproteins, erythrocytes and aorta. These same treated groups showed also lower serum isoprostane levels. However, serum paraoxonase activity and HDL-antioxidant property were improved only by CPH compared to CG. SOD activity of aorta and erythrocytes was higher in CPH but in SPH group, SOD activity was lower in these tissues and remained unchanged in serum. Furthermore, CPH and SPH stimulated glutathione peroxidase and catalase activities of aorta and erythrocytes. In CPH group, nitric oxide levels of serum, erythrocytes and aorta were increased by respectively 1.4- to 1.8-fold compared to CG and SPH. In addition, among the three groups, CPH exhibited the best anti-inflammatory effect by lowering serum C reactive protein, uric acid and albumin concentrations. CONCLUSIONS: SPH and particularly CPH possess antioxidant and anti-inflammatory properties and could be useful as nutraceuticals for health improving and preventing numerous disorders such as cardiovascular diseases.

Abstract
Gentianella acuta (G. acuta) has been widely used as a traditional medicine by Chinese Mongolian populations for the treatment of heart diseases and has also been tested in modern pharmacological experiments. However, the effects of G. acuta on cardiovascular damage and inflammation under conditions of hypercholesterolaemia remain unclear. The present study investigated the effects and mechanisms of the water extract of G. acuta on cardiovascular damage and inflammation caused by a high-cholesterol diet. Male Sprague-Dawley rats were fed a high-cholesterol diet for 4 weeks to establish the hypercholesterolaemia rat model, and they were administered physiological saline or 1.2 g/kg of G. acuta by gavage starting from the 15th day. After the last administration, the blood, heart and thoracic aorta samples were collected and examined. It was revealed that G. acuta treatment could ameliorate cardiomyocyte disorder and thoracic aortic vessel wall damage, reduce serum lipid levels and inflammatory factors and improve heart function. Compared with the Model group, the serum levels of triglycerides, total cholesterol, low-density lipoprotein and tumour necrosis factor-α were decreased, and the high-density lipoprotein and interleukin-10 levels were increased in the Model-G group. Moreover, in both the heart and thoracic aorta, G. acuta reduced the expression and phosphorylation of inhibitor of nuclear factor kappa-B kinase β (IKKβ), inhibitor of NF-κB-α (IκBα) and p-nuclear factor kappa-B (NF-κB). Therefore, G. acuta may exert an inhibitory effect on the IKK/IκB/NF-κB signalling pathway to protect the heart and thoracic aorta in hypercholesterolaemic rats.

Abstract
Lifestyle plays an important role in the development of noncommunicable diseases such as diabetes, hypertension, dyslipidemia, and obesity, in addition to a poor diet loaded with simple carbohydrates and saturated fats. This was a trial with a randomized, analytical, longitudinal, and prospective quasi-experimental design, which was divided into 2 phases: the first with healthy subjects with an age range between 18 to 30 y and normal BMI (18.5-24.9). The second phase was subjected with familial hypercholesterolemia aged between 18 to 45 y and overweight (25-29.9). For those subjects who frequently consumed vegetable oil of both Vitis vinifera L., or Persea americana L. (10 mL), they presented a significant reduction in anthropometric measures and in biochemical variables such as capillary glucose and increased HDLc. The vegetable oils of Persea americana L., and Vitis vinifera L., can act as adjuvants for the treatment of noncommunicable diseases.

Abstract
Avocado is a subtropical/tropical fruit with creamy texture, peculiar flavor, and high nutritional value. Due to its high oil content, a significant quantity of avocado fruit is used for the production of oil using different methods. Avocado oil is rich in lipid-soluble bioactive compounds, but their content depends on different factors. Several phytochemicals in the oil have been linked to prevention of cancer, age-related macular degeneration, and cardiovascular diseases and therefore have generated an increase in consumer demand for avocado oil. The aim of this review is to critically and systematically analyze the worldwide production and commercialization of avocado oil, its extraction methods, changes in its fat-soluble phytochemical content, health benefits, and new trends and applications. There is a lack of information on the production and commercialization of the different types of avocado oil, but there are abundant data on extraction methods using solvents, centrifugation-assisted aqueous extraction, mechanical extraction by cold pressing (varying concentration and type of enzymes, temperature and time of reaction, and dilution ratio), ultrasound-assisted extraction, and supercritical fluid to enhance the yield and quality of oil. Extensive information is available on the content of fatty acids, although it is limited on carotenoids and chlorophylls. The effect of avocado oil on cancer, diabetes, and cardiovascular diseases has been demonstrated through in vitro and animal studies, but not in humans. Avocado oil continues to be of interest to the food, pharmaceutical, and cosmetic industries and is also generating increased attention in other areas including structured lipids, nanotechnology, and environmental care.

Abstract
Ischemic heart disease and stroke are two main causes of death that have prevailed for more than 15 years. Dyslipidemia and its parameters like hypercholesterolemia, hypertriglyceridemia, increase in low-density cholesterol, and a reduction of high-density cholesterol have been related with heart disease and risk of stroke. Approaches to improve the health and specifically reduce the risk of heart disease, such as medications and dietary interventions have been effective, but there are other potential sources of biological compounds that could have an effect due to their antioxidant properties. Avocado is a commonly consumed fruit especially its pulp, while the peel, seed, and leaf are usually discarded as waste. Some researchers have reported antioxidant, hepatoprotective, gastroprotective, lipid-lowering, and hypoglycemic effects in these wastes. In this review article, we have summarized the current evidence on the effect of biological compounds from avocado waste on dyslipidemia parameters in preclinical models. Also, we have included the compound extracted and the extraction method from the selected articles.

Abstract
All food scientists must utilize plants for their application as functional foods to reduce hypercholesterolemia incidence through diet. Canarium odontophyllum (dabai) is a novel source for new healthy oil and functional foods. In this work, we evaluate the hepatoprotective effects of supercritical carbon dioxide (SC-CO2) extracted dabai pulp oil (DPO) and defatted dabai pulp (DDP) against hypercholesterolemia elicited by a high-cholesterol diet in rats. Our results show that DPO and DDP supplementation exerted beneficial hypocholesterolemic effects against the high-cholesterol diet-fed rat. Nevertheless, supplementation with DDP revealed superior total cholesterol, low-density lipoprotein, and HMG-CoA reductase lowering efficacy (p < 0.05). Supplementation of either DPO or DDP did not significantly affect AST and ALT levels than normal rats (p > 0.05). Therefore, DDP and DPO are considered as having no toxicological significance. The histological section of rats treated with DPO and DDP showed improved steatosis in hepatocytes. HPLC analysis revealed that DPO and DDP contained syringic acid, which plays an important role in the beneficial effect. In conclusion, our results support the hypocholesterolemic and hepatoprotective effects of DPO and DDP in the hypercholesterolemic rats model.

Abstract
Dabai pulp oil (DPO) is new oil extracted from the pulp of Canarium odontophyllum. The quality and efficacy of DPO are needed to promote its potential as a new alternative fat. Therefore, we investigate the quality of DPO, which includes moisture and volatile content (MVC), free fatty acid content (FFA), iodine value (IV), and peroxide value (PV). Furthermore, we evaluate the efficacy of DPO against hypercholesterolemia elicited by a high-cholesterol diet in rats. The MVC of DPO was <0.001 ± 0.00%. Next, the FFA in DPO was 2.57 ± 0.03%, and the IV of DPO was 53.74 ± 0.08 g iodine/100 g oil. Meanwhile, the PV of DPO was 4.97 ± 0.00 mEq/kg. Supplementation of DPO in hypercholesterolemic rats for 30 days revealed the hypocholesterolemic effect (significant reduction of total cholesterol, triglyceride, and 3-hydroxy-3-methylglutaryl-CoA reductase) accompanied by a significant reduction of inflammatory markers (C-reactive protein, interleukin-6 and tumour necrosis factor-α), and lipid peroxidation (MDA). We also observed a significant improvement of lipoprotein lipase (LPL) and antioxidant capacities (total antioxidant status, superoxide dismutase, glutathione peroxidase, and catalase) of the rats. The results on the quality and efficacy of locally made DPO suggest its potential use as a healthy alternative fat in the future.

Avocado oil (Persea americana) protects SH-SY5Y cells against cytotoxicity triggered by cortisol by the modulation of BDNF, oxidative stress, and apoptosis molecules. J Food Biochem 2021; 45:e13596. [PMID: 33480081 DOI: 10.1111/jfbc.13596] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 12/01/2020] [Accepted: 12/04/2020] [Indexed: 12/13/2022]
Abstract
Chronic psycho-environmental stress can induce neurological dysfunction due to an increase in cortisol levels. It is possible that some food supplements could attenuate its negative impact, such as avocado oil (AO), which is rich in fatty acids with beneficial effects on the brain. This hypothesis was tested by an in vitro model using undifferentiated neuroblastoma cells (SH-SY5Y) exposed to hydrocortisone (HC), an active cortisol molecule with and without AO-supplementation. Cortisol can induce oxidative stress, apoptosis events, and a lowering effect on brain-derived neurotrophic factor (BDNF), a neurogenic molecule. As AO protective effects on HC-exposed cells could involve these routes, some markers of these routes were compared among neuroblastoma cultures. In the first assay, the range concentrations of HC exposure that trigger cell mortality and range AO-concentrations that could revert the HC effect. AO at all concentrations tested (2-30 µg/ml) did not present a cytotoxic effect on SH-SY5Y cells, whereas HC at 0.3-10 ng/ml had a dose-dependent cytotoxic effect on these cells. From these results, HC at 10 ng/ml and AO at 5 µg/ml were chosen for mechanistic analysis. AO was able to decrease the oxidative molecules; however, both AO- and HC-induced differential and varied gene expression modulation of these enzymes. AO partially reverted the protein and gene expression of apoptotic markers that were higher in HC-exposed cells. AO also increases the BDNF levels, which are lower HC-exposed cultures. The results indicate that AO could be a beneficial supplement in situations where cortisol levels are elevated, including chronic psycho-environmental stress. PRACTICAL APPLICATIONS: Psychological chronic stress that induces high cortisol exposure has been linked to premature aging and decreased healthy life expectancy. Neurobiological models involving cortisol have suggested a neurotoxic effect of this molecule, increasing the risk of psychiatric and other CNTDs. This effect can have a high impact mainly in infants and elderly people. In child abuse situations, chronic cortisol exposure could induce extensive apoptosis events, causing impairment in synaptogenesis. In both age groups, chronic cortisol exposure increased the risk of psychiatric conditions, especially anxiety and major depression. However, it is possible that the negative effects associated with chronic cortisol exposure could be attenuated by some food supplements. This is the case for molecules acquired through diet, such as polyunsaturated fatty acids (PUFAs), including omega-3. As inadequate omega-3 levels in the brain can increase the risk factor for neuropsychiatric disorders, it is possible to infer that some from food supplements, such as avocado oil, could attenuate the neurotoxic effects of chronic cortisol exposure. This hypothesis was tested using an exploratory in vitro protocol, and the results suggested that avocado oil could be used as a cytoprotective food supplement by decreasing the oxidative stress and apoptotic events induced by cortisol.

Abstract
A source of functional food can be utilized from a source that might otherwise be considered waste. This study investigates the hypocholesterolemic effect of defatted dabai pulp (DDP) from supercritical carbon dioxide extraction and the metabolic alterations associated with the therapeutic effects of DDP using 1H NMR urinary metabolomic analysis. Male-specific pathogen-free Sprague-Dawley rats were fed with a high cholesterol diet for 30 days to induce hypercholesterolemia. Later, the rats were administered with a 2% DDP treatment diet for another 30 days. Supplementation with the 2% DDP treatment diet significantly reduced the level of total cholesterol (TC), triglyceride, low-density lipoprotein (LDL), and inflammatory markers (C-reactive protein (CRP), interleukin 6 (IL6) and tumour necrosis factor-α (α-TNF)) and significantly increased the level of antioxidant profile (total antioxidant status (TAS), superoxide dismutase (SOD), glutathione peroxide (GPX), and catalase (CAT)) compared with the positive control group (PG) group (p < 0.05). The presence of high dietary fibre (28.73 ± 1.82 g/100 g) and phenolic compounds (syringic acid, 4-hydroxybenzoic acid and gallic acid) are potential factors contributing to the beneficial effect. Assessment of 1H NMR urinary metabolomics revealed that supplementation of 2% of DDP can partially recover the dysfunction in the metabolism induced by hypercholesterolemia via choline metabolism. 1H-NMR-based metabolomic analysis of urine from hypercholesterolemic rats in this study uncovered the therapeutic effect of DDP to combat hypercholesterolemia.

Abstract
This study investigated the leaves of Clinacanthus nutans for its bioactive compounds and acute and subacute toxicity effects of C. nutans ethanolic leaf extract (CELE) on blood, liver and kidneys of ICR mice. A total of 10 8-week-old female mice were divided into groups A (control) and B (2000 mg/kg) for the acute toxicity study. A single dose of 2000 mg/kg was administered to group B through oral gavage and mice were monitored for 14 days. In the subacute toxicity study, mice were divided into five groups: A (control), B (125 mg/kg), C (250 mg/kg), D (500 mg/kg) and E (1000 mg/kg). The extract was administered daily for 28 days via oral gavage. The mice were sacrificed, and samples were collected for analyses. Myricetin, orientin, isoorientin, vitexin, isovitexin, isookanin, apigenin and ferulic acid were identified in the extract. Twenty-eight days of continuous oral administration revealed significant increases (p < 0.05) in creatinine, ALT and moderate hepatic and renal necrosis in groups D and E. The study concluded that the lethal dose (LD50) of CELE in mice is greater than 2000 mg/kg and that repeated oral administrations of CELE for 28 days induced hepatic and renal toxicities at 1000 mg/kg in female ICR mice.

Abstract
Obesity is a worldwide epidemic and is one of the factors involved in the etiology of type 2 diabetes mellitus. Obesity induces low-grade inflammation and oxidative stress. The treatment for obesity involves changes in diet, physical activity, and even medication and surgery. Currently, the use of nutraceutical compounds is associated with health benefits. Ginger and avocado are used for many people all around the world; however, its effect as a nutraceutical compound is less known by the general population. For this reason, we searched information of the literature to point its effects on distinct mechanisms of defense against the obesity its comorbidities. The present review aimed showing that these nutraceuticals may be useful in obesity treatment. Reports have shown that ginger and avocado induce antioxidant and anti-inflammatory effects by improving enzymatic activity and modulating obesity-related impairments in the anti-inflammatory system in different tissues, without side effects. Furthermore, ginger and avocado were found to be effective in reversing the harmful effects of obesity on blood lipids. In conclusion, on the basis of the positive effects of ginger and avocado in in vitro, animal, and human studies, these nutraceuticals may be useful in obesity treatment.

Abstract
Avocado oil is prized for its high nutritional value due to the substantial amounts of triglycerides (TGs) and unsaturated fatty acids (FAs) present. While avocado oil is traditionally extracted from mature fruit flesh, alternative sources such as avocado seed oil have recently increased in popularity. Unfortunately, sufficient evidence is not available to support the claimed health benefit and safe use of such oils. To address potential quality issues and identify possible adulteration, authenticated avocado oils extracted from the fruit peel, pulp and seed by supercritical fluid extraction (SFE), as well as commercial avocado pulp and seed oils sold in US market were analyzed for TGs and FAs in the present study. Characterization and quantification of TGs were conducted using UHPLC/ESI-MS. Thirteen TGs containing saturated and unsaturated fatty acids in avocado oils were unambiguously identified. Compared to traditional analytical methods, which are based only on the relative areas of chromatographic peaks neglecting the differences in the relative response of individual TG, our method improved the quantification of TGs by using the reference standards whenever possible or the reference standards with the same equivalent carbon number (ECN). To verify the precision and accuracy of the UHPLC/ESI-MS method, the hydrolysis and transesterification products of avocado oil were analyzed for fatty acid methyl esters using a GC/MS method. The concentrations of individual FA were calculated, and the results agreed with the UHPLC/ESI-MS method. Although chemical profiles of avocado oils from pulp and peel are very similar, a significant difference was observed for the seed oil. Principal component analysis (PCA) based on TG and FA compositional data allowed correct identification of individual avocado oil and detection of possible adulteration.

Abstract
The main function of blood platelets is to form hemostatic plugs and enable thrombosis. These properties, however, can be greatly influenced by dietary components which may inhibit certain steps of platelet activation, including platelet aggregation. Such inhibition can play a role in the prophylaxis and treatment of cardiovascular diseases associated with blood platelet hyperactivation. In fact, plant and fish oils have been identified and specifically used for this purpose. Numerous in vivo and in vitro experiments have explored the potential use of these oils to inhibit platelet activation as well as their role in reducing oxidative stress and blood pressure, and lowering triglyceride and cholesterol. This chapter presents and compares the anti-platelet effects of fish and plant oils and their constituents, especially fatty acids. Studies on healthy subjects and patients with various cardiovascular diseases are also examined. Findings indicate that both fish and plant oils contain protective components with anti-platelet activity having clearly defined mechanisms of action. Although both are excellent sources of omega fatty acids and vitamins, plant oils contain components with cardioprotective benefit in hypercholesterolemics, i.e., phytosterols. Plant oils may hence play a key role in strategies for preventing and treating cardiovascular diseases associated with platelet hyperactivation. Further studies are clearly needed to determine the precise dose of these components needed for effective prophylaxis and treatment.
