Abstract
Until recently, the main pharmaceuticals used to control cholesterol and prevent cardiovascular disease (CVD) were statin-related drugs, known for their historical side effects. Therefore, there is growing interest in exploring alternatives, such as nutritional and dietary components, that could play a central role in CVD prevention. This review aims to provide a comprehensive understanding of how natural phytosterols found in various diets combat CVDs. We begin with a description of the overall approach, then we explore in detail the different direct and indirect mechanisms that contribute to reducing cardiovascular incidents. Phytosterols, including stigmasterol, β-sitosterol, ergosterol, and fucosterol, emerge as promising molecules within nutritional systems for protection against CVDs due to their beneficial effects at different levels through direct or indirect cellular, subcellular, and molecular mechanisms. Specifically, the mentioned phytosterols exhibit the ability to diminish the generation of various radicals, including hydroperoxides and hydrogen peroxide. They also promote the activation of antioxidant enzymes such as superoxide dismutase, catalase, and glutathione, while inhibiting lipid peroxidation through the activation of Nrf2 and Nrf2/heme oxygenase-1 (HO-1) signaling pathways. Additionally, they demonstrate a significant inhibitory capacity in the generation of pro-inflammatory cytokines, thus playing a crucial role in regulating the inflammatory/immune response by inhibiting the expression of proteins involved in cellular signaling pathways such as JAK3/STAT3 and NF-κB. Moreover, phytosterols play a key role in reducing cholesterol absorption and improving the lipid profile. These compounds can be used as dietary supplements or included in specific diets to aid control cholesterol levels, particularly in individuals suffering from hypercholesterolemia.

Carica papaya Reduces Muscle Insulin Resistance via IR/GLUT4 Mediated Signaling Mechanisms in High Fat Diet and Streptozotocin-Induced Type-2 Diabetic Rats. Antioxidants (Basel) 2022; 11:antiox11102081. [PMID: 36290804 PMCID: PMC9598374 DOI: 10.3390/antiox11102081] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 10/15/2022] [Accepted: 10/17/2022] [Indexed: 11/19/2022] Open
Abstract
In the management of type 2 diabetes, oral antidiabetic drugs have several side effects, which in turn have led the pharmaceutical industry to search for good therapeutic, non-toxic and reliable drugs. Carica papaya (C. papaya) is one of several plants in nature that have been found to possess anti-diabetic properties. Despite studies being focused on the antidiabetic activity of C. papaya, the molecular mechanism against high fat diet induced insulin resistance is yet to be identified. The role of C. papaya was evaluated on insulin signaling molecules, such as the insulin receptor (IR) and glucose transporter-4 (GLUT4) in high fat, diet-streptozotocin induced type 2 diabetic rats, and analyzed the bioactive compounds of C. papaya against IR and GLUT4 via molecular docking and dynamics. The ethanolic extract of C. papaya leaves (600 mg/kg of body weight) was given daily to male wistar rats for 45 days and we observed the various biochemical parameters, gene expression analysis and histopathology of skeletal muscle. Molecular docking and dynamics were undertaken to understand the bioactive compounds with the greatest hit rate. C. papaya treatment was able to control blood glucose levels, the lipid profile and serum insulin, but it facilitated tissue antioxidant enzymes and IR and GLUT4 levels. The in-silico study showed that kaempferol, quercitin and transferulic acid were the top three ligands with the greatest hit rate against the protein targets. Our preliminary findings, for the first time, showed that C. papaya reinstates the glycemic effect in the diabetic skeletal muscle by accelerating the expression of IR and GLUT4.

Effect of a dietary intervention with functional foods on LDL-C concentrations and lipoprotein subclasses in overweight subjects with hypercholesterolemia: Results of a controlled trial. Clin Nutr 2021; 40:2527-2534. [PMID: 33932799 DOI: 10.1016/j.clnu.2021.02.048] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 12/14/2020] [Accepted: 02/28/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND & AIMS Cardiovascular diseases (CVDs) are the leading cause of global death. Hypercholesterolemia is among the main risk factors for developing cardiovascular events, and is highly prevalent in the Mexican population. The primary objective of the present work was to assess the effect of a dietary portfolio (DP) with functional foods containing dehydrated nopal, soy protein, chia seeds, inulin, and oats in LDL-C and TC concentrations of subjects with mild hypercholesterolemia. Also, we explored the changes in the profile of the lipoprotein subclasses measured by nuclear magnetic resonance spectroscopy (NMR). METHODS Sixty-two subjects (47 women, 15 men) with mild hypercholesterolemia (LDL-C, ≥130 ≤ 190 mg/dL, TC > 200 mg/dL) completed the randomized, parallel, controlled study. The dietary intervention was given in two stages. First, a dietary standardization stage with a low saturated fat diet (LSFD) which matched the habitual energy intake of the volunteers for 2-weeks, followed by 2.5 months of dietary intervention with a LSFD plus placebo (PL) or DP. RESULTS Subjects who consumed the LSFD + DP interventions had a significantly higher reduction of LDL-C (-18.05%, P = 0.003) and TC (-17.08%, P = 0.02) compared to volunteers who consumed an LSFD for the same period. Furthermore, the lipoprotein subclass profiling showed that the small low-density-lipoproteins, and the small high-density-lipoproteins significantly decreased (P = 0.04, P < 0.001, respectively), conveying a less atherogenic state. At the end of the study, 78% of the subjects who consumed LSFD + DP reduced their LDL-C below 160 mg/dL, and of these, 47% reduced it below 130 mg/dL. CONCLUSIONS Based on the results obtained from this study, the inclusion of functional foods as part of the lifestyle modifications is recommended to treat mild hypercholesterolemia and reduce cardiovascular risk. Registered under ClinicalTrials.gov Identifier no. NCT04148976.

Abstract
Antibiotics use in poultry as a growth promoter leads to the propagation of antibiotic-resistant microorganisms and incorporation of drug residues in foods; therefore, it has been restricted in different countries. There is a global trend to limit the use of antibiotics in the animal products. Prevention of the antibiotics use in the poultry diets led to the reduction in the growth performance. Consequently, there is a high demand for natural substances that lead to the same growth enhancement and beneficially affect poultry health. These constituents play essential roles in regulating the normal physiological functions of animals including the protection from infectious ailments. Nutraceuticals administration resulted beneficial in both infectious and noninfectious diseases. Being the natural components of diet, they are compatible with it and do not pose risks associated with antibiotics or other drugs. Nutraceuticals are categorized as commercial additives obtained from natural products as an alternative feed supplement for the improvement of animal welfare. This group includes enzymes, synbiotics, phytobiotics, organic acids and polyunsaturated fatty acids. In the present review, the summary of various bioactive ingredients that act as nutraceuticals and their mode of action in growth promotion and elevation of the immune system has been presented.

Beta-sitosterol attenuates insulin resistance in adipose tissue via IRS-1/Akt mediated insulin signaling in high fat diet and sucrose induced type-2 diabetic rats. Eur J Pharmacol 2020; 873:173004. [PMID: 32045603 DOI: 10.1016/j.ejphar.2020.173004] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 02/05/2020] [Accepted: 02/07/2020] [Indexed: 02/07/2023]
Abstract
In our previous study, we have shown that β-sitosterol (SIT) enhances glycemic control by increasing the activation of insulin receptor (IR) and glucose transporter 4 (GLUT4) proteins in adipose tissue. However, the possible role of SIT on the regulation of post-receptor insulin signal transduction is not known. Hence, the study was aimed to assess the effects of SIT on IRS-1/Akt mediated insulin signaling molecules in high-fat diet and sucrose induced type-2 diabetic rats. An oral effective dose of SIT (20 mg/kg b.wt) was given for 30 days to high fat-fed type-2 diabetic rats to find out whether SIT regulates IRS-1/Akt pathway of insulin signaling. The results showed that SIT attenuated the insulin receptor substrate-1 serine phosphorylation (p-IRS-1Ser636) (P = 0.0003). However, it up-regulated the mRNA expression of IR (P = 0.0036) and post-receptor insulin signaling molecules such as IRS-1 (P < 0.0001), β-arrestin-2 (P < 0.0058), Akt (P = 0.0008), AS160 (P = 0.0030) and GLUT4 (P < 0.0001) with a concomitant increase in the levels of IRS-1(P < 0.0001), p-IRS1-1Tyr632 (P = 0.0014), Akt (P < 0.0001), p-AktSer473/Thr308 (P = 0.0006; P < 0.0001), AS160 and p-AS160Thr642 (P < 0.0001) compared with type-2 diabetic rats. In Silico analysis was also performed and it showed that SIT possesses the greater binding affinity with β-arrestin-2, c-Src, and IRS-1 as well as Akt proteins and proved to attenuate insulin resistance as this study coincides with in vivo findings. Our present study clearly shows that SIT attenuates high fat diet-induced detrimental changes in adipose tissue. Therefore, it is concluded from the present findings that, SIT could be used as potential therapeutic phytomedicine for the management of type-2 diabetes.

β-Sitosterol Attenuates High Grain Diet-Induced Inflammatory Stress and Modifies Rumen Fermentation and Microbiota in Sheep. Animals (Basel) 2020; 10:ani10010171. [PMID: 31963945 PMCID: PMC7022687 DOI: 10.3390/ani10010171] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 01/10/2020] [Accepted: 01/13/2020] [Indexed: 12/22/2022] Open
Abstract
β-sitosterol (BSS) is a plant-derived natural bioactive compound, its cellular mechanism of anti-inflammatory activity has been proven recently. Little information is available regarding the application of BSS on ruminants under high grain diet. The objective of this study was to evaluate the effects of dietary BSS supplementation on inflammatory response, ruminal fermentation characteristics and the composition of the ruminal bacterial community under high grain diet. Eight rumen-cannulated Hu sheep (59.7 ± 4.8 kg of initial body weight) were randomly assigned into a replicated 4 × 4 Latin square design trial. Sheep were fed a high grain diet (non-fiber carbohydrate: neutral detergent fiber = 2.03) supplemented either with 0.25 (LBS), 0.5 (MBS), 1.0 (HBS) or without (CON) g BSS /kg dry matter diet. On day 21 of each period, rumen content samples were obtained at 6 h postfeeding, and blood samples were obtained before morning feeding. The data showed that compared with control group, Dietary BSS supplementation decreased serum concentrations of tumor necrosis factor, interleukin (IL)-6, and IL-1β. The ruminal pH and acetate concentration for BSS treatment were improved, while concentration of propionate, butyrate and lactate was decreased. The result of Illumina MiSeq sequencing of 16S rRNA gene revealed that BSS addition can increase the proportion of Prevotella_1, Rikenellaceae_RC9_gut_group, Prevotella_7, and Selenomonas_1, and decrease the proportion of Lachnospiraceae_NK3A20_group. These results indicated that BSS attenuates high grain diet-induced inflammatory response and modifies ruminal fermentation. In addition, the BSS dietary supplementation at the level of 0.5 g/kg is recommended in sheep.

Abstract
Simple Summary Fast growth of modern broilers induces their muscle abnormality and myopathy, and therefore could compromise meat quality attributes. Antibiotic growth promoters have been banned by European Union and restricted by other countries in livestock production due to the public concern about food safety and antibiotic resistance. The search for efficacious, environmentally friendly, safe, and consumer favorable feed additives have become a necessity to poultry meat production. β-sitosterol—the most abundant phytosterol similar to cholesterol in chemical structure—is found in several plant products. It was incorporated at four levels into broiler diets (40, 60, 80, and 100 mg/kg). Dietary β-sitosterol supplementation improved growth performance and breast muscle meat quality of broilers, and the improved meat quality may be related with the simultaneously enhanced oxidative status and mitochondrial biogenesis in the breast muscle. The β-sitosterol dietary supplementation at the level of 80 mg/kg is recommended in broilers Abstract The present study evaluated effects of β-sitosterol on growth performance, meat quality, oxidative status, and mitochondrial biogenesis of breast muscle in broilers. One-day-old chicks were allocated to five treatments of six replicates. Broilers were fed a basal diet supplemented either with 0 (control), 40, 60, 80, or 100 mg/kg β-sitosterol for 42 days. β-sitosterol linearly and quadratically reduced feed/gain ratio, lightness24h and cooking loss24h in breast muscle, whereas 2, 2-diphenyl-1-picrylhydrazyl scavenging activity of breast muscle followed an opposite trend. β-sitosterol linearly decreased drip loss24h and malondialdehyde content, whereas linearly increased pH24h, superoxide dismutase activity, and mRNA abundances of peroxisome proliferator-activated receptor γ coactivator 1α (PCG-1α) and mitochondrial transcription factor A (TFAM) in breast muscle. Compared with control, levels of β-sitosterol higher than 40 mg/kg reduced feed/gain ratio, muscular lightness24h, cooking loss24h, and malondialdehyde level, whereas increased muscular 2, 2-diphenyl-1-picrylhydrazyl scavenging activity, and mRNA abundances (except 60 mg/kg) of PCG-1α and TFAM. Eighty milligram/kilogram β-sitosterol increased muscular pH24h and superoxide dismutase activity, but decreased its drip loss24h. Therefore, β-sitosterol could improve growth performance and meat quality, oxidative status, and mitochondrial biogenesis of breast muscle in broilers. Furthermore, supplementation level of 80 mg/kg β-sitosterol is recommended for broiler diets.

Abstract
Adipose tissue is the primary site of storage for excess energy as triglyceride and it helps in synthesizing a number of biologically active compounds that regulate metabolic homeostasis. Consumption of high dietary fat increases stored fat mass and is considered as a main risk factor for metabolic diseases. Beta-sitosterol (β-sitosterol) is a plant sterol. It has the similar chemical structure like cholesterol. Clinical and experimental studies have shown that β-sitosterol has anti-diabetic, hypolipidemic, anti-cancer, anti-arthritic, and hepatoprotective role. However, effect of β-sitosterol on insulin signaling molecules and glucose oxidation has not been explored. Hence in the present study we aimed to discover the protective role of β-sitosterol on the expression of insulin signaling molecules in the adipose tissue of high-fat diet and sucrose-induced type-2 diabetic experimental rats. Effect dose of β-sitosterol (20 mg/kg b.wt, orally for 30 days) was given to high fat diet and sucrose-induced type-2 diabetic rats to study its anti-diabetic activity. Results of the study showed that the treatment with β-sitosterol to diabetes-induced rats normalized the altered levels of blood glucose, serum insulin and testosterone, lipid profile, oxidative stress markers, antioxidant enzymes, insulin receptor (IR), and glucose transporter 4 (GLUT4) proteins. Our present findings indicate that β-sitosterol improves glycemic control through activation of IR and GLUT4 in the adipose tissue of high fat and sucrose-induced type-2 diabetic rats. Insilico analysis also coincides with invivo results. Hence it is very clear that β-sitosterol can act as potent antidiabetic agent.

[PMID: 28233313 DOI: 10.1002/jsfa.8286] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2016] [Revised: 01/16/2017] [Accepted: 02/19/2017] [Indexed: 06/06/2023]
Abstract
BACKGROUND The effect of the addition of flaxseed oil (FO), phytosterols (PS) and polydextrose (PDX) on the physicochemical and sensory properties of milk was investigated, as they are known to impart health benefits. RESULTS For incorporating PS, a hydrophobic substance, FO and milk fat (MF) as an oil source, an emulsifier (DATEM) and PDX solution as an aqueous medium were used for the preparation of emulsion. Three emulsion formulations A (8 g PS, 8 g FO, 20 g PDX, 6 g MF), B (10 g PS, 10 g FO, 20 g PDX, 4 g MF) and C (12 g PS, 12 g FO, 20 g PDX, 2 g MF) were prepared and added individually to milk at a level of 50 g kg-1 . Based on sensory evaluation, formulation B was selected for fortification of milk. The fortified milk kept well at refrigerated temperature for 1 week, and changes in sensory, physicochemical and microbiological properties were comparable to those of control milk. The level of fortificants did not decrease in the milk after 1 week of storage. CONCLUSION An emulsion containing FO, PS and PDX could successfully serve as a potential delivery system for enhancing the nutritional and therapeutic potential of milk. © 2017 Society of Chemical Industry.

Abstract
In recent years, there has been growing interest in the possible use of nutraceuticals to improve and optimize dyslipidemia control and therapy. Based on the data from available studies, nutraceuticals might help patients obtain theraputic lipid goals and reduce cardiovascular residual risk. Some nutraceuticals have essential lipid-lowering properties confirmed in studies; some might also have possible positive effects on nonlipid cardiovascular risk factors and have been shown to improve early markers of vascular health such as endothelial function and pulse wave velocity. However, the clinical evidence supporting the use of a single lipid-lowering nutraceutical or a combination of them is largely variable and, for many of the nutraceuticals, the evidence is very limited and, therefore, often debatable. The purpose of this position paper is to provide consensus-based recommendations for the optimal use of lipid-lowering nutraceuticals to manage dyslipidemia in patients who are still not on statin therapy, patients who are on statin or combination therapy but have not achieved lipid goals, and patients with statin intolerance. This statement is intended for physicians and other healthcare professionals engaged in the diagnosis and management of patients with lipid disorders, especially in the primary care setting.

Abstract
The incidence of CHD is still increasing, which underscores the need for new preventive and therapeutic approaches to decrease CHD risk. In this respect, increasing apoA-I concentrations may be a promising approach, especially through increasing apoA-I synthesis. This review first provides insight into current knowledge on apoA-I production, clearance, and degradation, followed by a systematic review of dietary and novel pharmacological approaches to target apoA-I metabolism. For this, a systematic search was performed to identify randomized controlled intervention studies that examined effects of whole foods and (non)nutrients on apoA-I metabolism. In addition, novel pharmacological approaches were searched for, which were specifically developed to target apoA-I metabolism. We conclude that both dietary components and pharmacological approaches can be used to increase apoA-I concentrations or functionality. For the dietary components in particular, more knowledge about the underlying mechanisms is necessary, as increasing apoA-I per se does not necessarily translate into a reduced CHD risk.

Abstract
Beta-sitosterol (BS) is a phytosterol, widely distributed throughout the plant kingdom and known to be involved in the stabilization of cell membranes. To compile the sources, physical and chemical properties, spectral and chromatographic analytical methods, synthesis, systemic effects, pharmacokinetics, therapeutic potentials, toxicity, drug delivery and finally, to suggest future research with BS, classical as well as on-line literature were studied. Classical literature includes classical books on ethnomedicine and phytochemistry, and the electronic search included Pubmed, SciFinder, Scopus, the Web of Science, Google Scholar, and others. BS could be obtained from different plants, but the total biosynthetic pathway, as well as its exact physiological and structural function in plants, have not been fully understood. Different pharmacological effects have been studied, but most of the mechanisms of action have not been studied in detail. Clinical trials with BS have shown beneficial effects in different diseases, but long-term study results are not available. These have contributed to its current status as an "orphan phytosterol". Therefore, extensive research regarding its effect at cellular and molecular level in humans as well as addressing the claims made by commercial manufacturers such as the cholesterol lowering ability, immunological activity etc. are highly recommended.

Abstract
BACKGROUND Cardiovascular diseases are the primary cause of death and the leading cause of disability in industrialized countries. Dyslipidemia is a major independent and reversible risk factor for these diseases: it is estimated that a reduction of 1 mmol/l (38 mg/dl) of LDL cholesterol is associated with a risk of developing a cardiovascular complication reduced by 25%, a reduction potentially achieved by life-style improvement associated to adequate dietary supplementation with bioactive substances. AIM The aim of this review is to focus on the major phytochemical nutraceuticals combinations supported by clinical trials that have demonstrated positive effects in the treatment of dyslipidemia. MAIN TEXT There are many nutraceuticals with significant lipid-lowering properties: most of them are used in association with a low dosage, because that permits to reduce the risk of side effects and theoretically to improve efficacy. In fact, natural products with different synergetic lipid-lowering could be combined: they can reduce the absorption of lipids from the bowel and/or increase their excretion (soluble fibers, plant sterols, probiotics), enhance the hepatic uptake of cholesterol (berberine, soybean proteins), inhibit Hydroxy-Methil-Gglutaryl Coenzyme A reductase enzyme and consequently the hepatic synthesis of cholesterol (monacolins, policosanols, allicin, soybean proteins, bergamot); furthermore some products are able to reduce the oxidation of the LDL and increase the thermogenesis and lipid metabolism (chlorogenic acid). CONCLUSION Rational combinations of nutraceuticals with different lipid-lowering activities, whether associated with an appropriate lifestyle, should provide an alternative to drug treatment in patients in primary cardiovascular disease prevention with mildly added cardiovascular risk and in some statin-intolerant patients.

Abstract
Reducing elevated LDL-cholesterol is a key public health challenge. There is substantial evidence from randomised controlled trials (RCT) that a number of foods and food components can significantly reduce LDL-cholesterol. Data from RCT have been reviewed to determine whether effects are additive when two or more of these components are consumed together. Typically components, such as plant stanols and sterols, soya protein, β-glucans and tree nuts, when consumed individually at their target rate, reduce LDL-cholesterol by 3-9 %. Improved dietary fat quality, achieved by replacing SFA with unsaturated fat, reduces LDL-cholesterol and can increase HDL-cholesterol, further improving blood lipid profile. It appears that the effect of combining these interventions is largely additive; however, compliance with multiple changes may reduce over time. Food combinations used in ten 'portfolio diet' studies have been reviewed. In clinical efficacy studies of about 1 month where all foods were provided, LDL-cholesterol is reduced by 22-30 %, whereas in community-based studies of >6 months' duration, where dietary advice is the basis of the intervention, reduction in LDL-cholesterol is about 15 %. Inclusion of MUFA into 'portfolio diets' increases HDL-cholesterol, in addition to LDL-cholesterol effects. Compliance with some of these dietary changes can be achieved more easily compared with others. By careful food component selection, appropriate to the individual, the effect of including only two components in the diet with good compliance could be a sustainable 10 % reduction in LDL-cholesterol; this is sufficient to make a substantial impact on cholesterol management and reduce the need for pharmaceutical intervention.

Abstract
Background Plant sterols are an established non-pharmacological means to reduce total and LDL blood cholesterol concentrations and are therefore recommended for cholesterol management by worldwide-renown health care institutions. Their efficacy has been proven in many types of foods with the majority of trials conducted in spreads or dairy products. As an alternative to dairy products, soy based foods are common throughout the world. Yet, there is little evidence supporting the efficacy of plant sterols in soy-based foods. The objective of this study was to investigate the effect of a soy drink enriched with plant sterols on blood lipid profiles in moderately hypercholesterolemic subjects. Methods In a randomized, placebo-controlled double-blind mono-centric study, 50 subjects were assigned to 200 ml of soy drink either enriched with 2.6 g plant sterol esters (1.6 g/d free plant sterol equivalents) or without plant sterols (control) for 8 weeks. Subjects were instructed to maintain stable diet pattern and physical activity. Plasma concentrations of lipids were measured at initial visit, after 4 weeks and after 8 weeks. The primary measurement was the change in LDL cholesterol (LDL-C). Secondary measurements were changes in total cholesterol (TC), non-HDL cholesterol (non-HDL-C), HDL cholesterol (HDL-C) and triglycerides. Results Regular consumption of the soy drink enriched with plant sterols for 8 weeks significantly reduced LDL- C by 0.29 mmol/l or 7% compared to baseline (p < 0.05). TC and non-HDL-C concentrations decreased by 0.26 mmol/l and 0.31 mmol/l (each p < 0.05), respectively. Mean reductions in total, LDL and non-HDL cholesterol were significantly greater than in the placebo group (p < 0.05). HDL-C and triglycerides were not affected. Compliance was very high (>96%), and products were well tolerated. Conclusion Daily consumption of a plant sterol-enriched soy drink significantly decreased total, non-HDL and LDL cholesterol and is therefore an interesting and convenient aid in managing mild to moderate hypercholesterolemia.

Abstract
To investigate the effects of dietary proteins on the level of serum total cholesterol (TC), triglyceride (TG) and high density lipoprotein (HDL), 32 male Wistar rats were randomly divided in control and 3 experimental groups (El, E2 and E3). The feeding regimes of rats were as follow: control, standard diet; E1, a cholesterol free diet containing 20% soybean protein; E2, a cholesterol free diet containing 20% casein and E3, a cholesterol free diet containing 10% soybean protein and 10% casein. The experimental period was 11 weeks but at the end of 7th week the diets of E1 and E2 groups were crossed over for the next 4 weeks. Blood samples were collected weekly, via the ophthalmic sinus and the serum levels TC, TG and HDL were measured. In comparison with control group, the results show that at the end of 7th week TC levels in E1 and E2 groups were significantly (p<0.05) increased while HDL level unchanged and the TC value of E2 was bigger (not significant) than E1. However by crossing over the diets, the TC level was significantly (p<0.05) diminished in E2 while TG value remarkably (p<0.05) increased. These results indicate that soybean protein may insert its hypocholesterolemic effect in hypercholestrolemic condition than in normolipidemic condition.

Abstract
Caesalpinia bonduc Roxb. (Caesalpiniaceae) seed extracts were screened for adaptogenic activity using cold stress model and swim endurance model, the seed coat as well as kernel extracts showed significant antistress activity when administered orally at a dose of 300 mg/kg. The extracts significantly increased the swim endurance time. Stress induced animals exhibited hypoglycaemia as well as depletion in serum cortisol level and increased total leukocyte count, the extracts showed a significant action in overcoming these imbalances. It was also found that extracts proved efficient in controlling the hyperlipidaemic condition due to stress.

Abstract
OBJECTIVES Cardiovascular disease (CVD) is the leading cause of death in women. Hyperlipidemia is a major risk factor for CVD, but research suggests that metabolic syndrome and type 2 diabetes are also key factors in CVD in postmenopausal women. Most dietary programs, however, focus only on hyperlipidemia and not on insulin resistance associated with diabetes and metabolic syndrome. This 12-wk trial compared the effects of a dietary program combining a low glycemic index diet with a functional food delivering 30 g of soy protein and 4 g of phytosterols per day (LGID) with a standard dietary program (American Heart Association Step 1 diet; AHAD) in postmenopausal women. METHODS Fifty-nine postmenopausal women (average age 54.6 y, range 44-65 y) with a body mass index of 27 to 39 kg/m2 were randomly assigned to the LGID or the AHAD program for 12 wk. Total caloric intake and exercise were matched in each arm. RESULTS Twenty-seven women completed the LGID program, and 26 completed the AHAD program. The participants on the LGID program showed statistically significant decreases in total cholesterol (15.8%, P = 0.0036 between-group comparison), low-density lipoprotein cholesterol (14.8%, P = 0.004 between-group comparison), and triacylglycerol (44.8%, P = 0.006 between-group comparison). In addition, significant improvements were observed in ratios of total to high-density lipoprotein cholesterol and of triacylglycerol to high-density lipoprotein cholesterol, blood pressure, and Framingham risk assessment for coronary heart disease compared with the AHAD program. CONCLUSIONS A significantly greater improvement was observed in CVD risk factors in postmenopausal women on the LGID program (incorporating 30 g of soy protein and 4 g of phytosterols per day) than with a standard therapy.

Abstract
BACKGROUND High doses of soy protein are able to decrease plasma cholesterolemia significantly, but they unbalance daily protein intake and strongly modify nutritional habits in patients. AIM OF THE STUDY To evaluate the antihypercholesterolemic efficacy of a low dose soy protein product with added beta-sitosterol (rapport = 4:1) in 36 moderately hypercholesterolemic subjects. METHODS The study was divided into 3 separate periods of 40 days each: a stabilization diet period, followed by a treatment period during which all subjects took 10 g of the test product once daily and, finally, a wash out period. The following parameters were monitored: weight, dietary habits, plasma lipid levels, glycemia, uric acid, fibrinogenemia and antibodies against oxidized LDL (ox-LDL Ab). RESULTS From the end of the stabilization diet period to the end of the supplementation with the soy protein product with added beta-sitosterol we observed a 19.64 +/- 20.32 mg/dL, 8.47 +/- 54.61 mg/dL, 1.69 +/- 10.92 mg/dL, and 7.06 +/- 16.66 mg/dL mean +/- SD decrease respectively in LDL-C (p < 0.001), TG (p = 0.358), VLDLs (p = 0.358) and apoB (p = 0.016) levels, associated with a 1.31 +/- 8.08 mg/dL and 1.03 +/- 19.09 mg/dL mean increase respectively in HDLC (p = 0.251) and apoAI (p = 0.749) plasma concentrations. The dietary supplementation did not influence Lp(a) (p = 0.984) and ox-LDL Ab (p = 0.953) plasma levels. A statistically significant correlation was observed for LDL-C plasma levels, between the end of the stabilization diet period and the end of the period of supplementation with soy proteins with added beta-sitosterols (p < 0.001). CONCLUSION Although further long-term clinical studies are necessary before claims can be made regarding the therapeutic effects of the tested formulation, the preliminary findings regarding its efficacy and safety as an antihypercholesterolemic agent are encouraging.

Abstract
National guidelines indicate patients with elevated low- density lipoprotein cholesterol should consume less than 7% of calories from saturated fat and less than 200 mg of cholesterol. Trans fatty acids should also be limited. Incorporation of functional foods, such as stanol-containing margarine, soy products, and soluble fiber-rich cereals and vegetables can provide further benefit. In addition to weight loss and physical activity, individuals with hypertriglyceridemia benefit from a diet moderate in fat and carbohydrate rather than a low-fat diet. Including monounsaturated or omega-3 fatty acids lowers serum triglycerides. Many of the dietary strategies to optimize serum lipids also contribute to glycemic control in patients with diabetes mellitus.
