3 Éster de estanol vegetal reduce el colesterol LDL Reduce el Colesterol LDL en un promedio de 10%No afecta el colesterol HDL2 DE ESTANOLES VEGETALES POR DÍA REDUCE EL COLESTEROL LDL EN10 %EU commission has approved in 2009 the following health claim to be used in plant stanol ester containing products: ” Plant stanol esters have been shown to lower/reduce blood cholesterol. High cholesterol is a risk factor in the development of coronary heart disease.” This is the strongest type of a health claim possible to get in EU, an Art health claim for reducing a risk factor for a disease. In order to bear the claim, the product must also provide on its labeling the following information to consumers: “Information to the consumer that the beneficial effect is obtained with a daily intake of 1,5-2,4 g plant stanols. Reference to the magnitude of the effect may only be made for foods within the following categories: yellow fat spreads, dairy products, mayonnaise and salad dressings. When referring to the magnitude of the effect, the entire range '7 to 10 %' and the duration to obtain the effect 'in 2 to 3 weeks' must be communicated to the consumer.” Read more at:FDA has approved a health claim for “Plant sterol/stanol esters and Risk of Coronary Heart Disease”. Suggested wording for the claim is “Diets low in saturated fat and cholesterol that include two servings of foods that provide a daily total of at least 3.4 grams of plant stanol esters in two meals may reduce the risk of heart disease. A serving of [name of food] supplies __ grams of plant stanol esters.” Read more at:

5 Estructura Molecular: Colesterol, estanoles y esteroles Phytosterols (i.e. plant stanols and plant sterols) are a group of compounds that are found in plant-based foods like cereals and vegetable oils. The amounts of phytosterols found naturally in foods are too small to produce significant reductions in human serum cholesterol levels. However, foods enriched with phytosterol esters have been shown to effectively lower serum cholesterol levels.Plant stanols are esterified with vegetable oil fatty acids in order to ensure their bioavailability and the good quality of the end food product. 2 g of plant stanols weight about 3.4 g when they are esterified into plant stanol esters.Plant stanols and plant sterols differ from each other by molecular structure (plant stanols are saturated forms of plant sterols), which leads to differences in their absorbtion efficacy, serum levels, metabolism, excretion and efficacy at intakes above 2 g/d.The absorption rate of plant sterols is roughly ten times higher than the absorption rate of corresponding plant stanols: the absorption rate of plant sterols is approximately 0.5-2% and the absorption rate of plant stanols is approximately % (Ostlund et al. 2002). Consumption of plant stanol ester reduces the absorption of both cholesterol and plant sterols, resulting in reduced serum levels of both cholesterol and plant sterols. Apposed to that, consumption of plant sterol ester only reduces the absorption of cholesterol and leads to increased serum levels of plant sterols (Hallikainen et al. 2000).On a normal diet, serum concentrations of plant stanols are low, typically 10 – 15 μg/dl (Hallikainen et al. 2000) A daily intake of 2 g plant stanols (as plant stanol ester) increases serum plant stanol concentrations to 20 – 30 μg/dl. Serum levels of plant stanols remains at low levels even with high daily intake of plant stanols (up to 9 g/d), (Gylling et al. 2010a, Mensink et al. 2010) On a normal diet, serum concentrations of plant sterols are typically much higher than those of plant stanols, namely 350 – 800 μg/dl. A daily intake of 2 g plant sterols (as plant sterol ester) increases blood plant sterol concentrations to 500 – 1000 μg/dl (Hallikainen et al. 2000).Plant stanols are stable molecules that are not metabolized in the body (Lütjohann et al. 1993). Plant sterols can be metabolized by intestinal microbes to secondary metabolites (Weststrate et al. 1999). Plant stanols are more effectively eliminated from the body than the corresponding plant sterols. Ostlund et al studied the decay of intravenously injected dideuterated tracers and found that the half-life (t½) of plant stanols was consistently shorter than that for corresponding plant sterols.Consumption of plant stanols dose-dependently reduces serum cholesterol levels even at intakes higher than around 2 g/d (Gylling et al. 2010b, Mensink et al. 2010, Musa-Veloso et al. 2011, Musa-Veloso and Poon 2011). Apposed to that, higher intakes of plant sterols than around 2 g/d have not been shown to result in enhanced cholesterol-lowering efficacy (Davidson et al. 2001, Hendriks et al. 1999, Musa-Veloso et al. 2011, Musa-Veloso and Poon 2011, Noakes et al. 2005).
6 Mecanismo de accionEl Ester de Estanol Vegetal Reduce la Absorcion del Colesterol en el Intestino DelgadoSIN ESTANOL VEGETAL~50% del colesterol se absorbeCON ESTANOL VEGETAL~20% of colesterol se absorbeColesterolEster de Estanol VegetalPlant stanol ester works by inhibiting the absorption of cholesterol in the small intestine. In the intestine, plant stanol ester is hydrolyzed into plant stanol, the bioactive ingredient, and fatty acid. Fatty acids are digested normally. Plant stanol is able to replace cholesterol in mixed micelles due to similar molecular structure. Cholesterol that is not solubilized into a mixed micelle can not be absorbed, and significantly more cholesterol is excreted from the body.Apart from this rather simple, mechanistical mechanism, plant stanols are believed to affect other mechanisms related to cholesterol absorption. As a single-dose of plant stanols a day has been found to be as effective as the same dose divided over several meals a day, there must be some longer affecting mechanism also playing role. It has been suggested that plant stanols may induce ATP binding cassette transporter A1 (ABCA1) expression, which indicates that within the enterocyte, plant stanols increase the ABCA1 -mediated cholesterol efflux back into the intestinal lumen. Other, more recent finding is that plant stanols may stimulate cholesterol excretion via non-biliary route, the trans intestinal cholesterol excretion (TICE) (Brufau, 2011). TICE was discovered in in vivo-studies when it was suggested that the hepatobiliary cholesterol secretion might not be the only route for cholesterol excretion into the intestinal lumen. It has been demonstrated that cholesterol is secreted throughout the entire length of the small intestine (van der Velde 2007). These findings are very preliminary, however.

Cholesterol absorbtion efficiency was calculated by the altered 14C/3H ratio in stools as compared with the fed ratio. Fecal cholesterol as fecal neutral sterols, bile acids and plant sterols were quantitated by gas-liquid chromatography. Dietary intake of fatty acids and cholesterol were determined from the 7-day diaries by a computer method applied to the country’s dietary ingredients.Compared to control period, intervention with plant stanol ester spread containing 3 g/d plant stanols decreased the cholesterol absorption efficacy by 45%. Plant stanol ester increased the fecal elimination of both biliary and dietary cholesterol. This resulted in 15 % reduction in LDL-cholesterol compared to placebo period.Adapted from Gylling et al.

When the consumption is maintained daily, the effect is lasting.In the study by Athyros et al. 150 mildly hypercholesterolemic subjects (TC 5.2 – 6.4 mmol/L; mg/dl) were randomized after a run-in period of 4 weeks into three categories for 4 months; one using regular spread (placebo) (n=50); one adviced to consume Mediterranean diet (n=50) and one using plant stanol ester containing spread (2 g/d of plant stanols) (n=50). During the run-in period subjects were advised to follow step I hypolipidemic diet. Those subjects who were using either placebo spread or plant stanol ester spread continued on this diet throughout the study.Compared to the control group, the subjects using the plant stanol ester spread had their LDL cholesterol reduced by 16 % already after the 1st month of intervention. The reduction sustained on this level throughout the study. The improvements in the diets of those subjects who followed the mediterranean diet resulted in significant 7 % reduction in LDL cholesterol compared to control, but only after 4 months of intervention.Athyros et al.

It showed that using spread with added plant stanol ester reduced LDL-cholesterol significantly and that the effect was sustained throughout the study.The study was an one-year, randomized, double-blind study with 153 mildly hypercholesterolemic subjects. 51 consumed control margarine with no plant stanols and 102 consumed intervention margarine with 2.6 g plant stanols as plant stanol ester for six months, after which the plant stanol ester margarine group was further randomized to either continue with the margarine with 2.6 g of plant stanols/day (n=51) or change to margarine with 1.8 g of plant stanols/day for the remaining 6 months. Subjects were not to change their habitual western diet apart from the substitution of their regular spread with the test margarines (24 g/d in each group).With 2.6 g/day of plant stanols as plant stanol ester, LDL-cholesterol reduced by 13 % compared to the control at 12 months.Miettinen et al.

A randomized, double-blind, placebo-controlled, cross-over study with 39 healthy normo- or mildly hypercholesterolemic subjects. Each consumed in a random order: no plant stanols; 2.5 g plant stanols at lunch; and 2.5 g plant stanols divided over the three meals (0.42 g at breakfast, 0.84 g at lunch and 1.25 g at dinner: proportional to dietary cholesterol intake).Each period lasted for 4 weeks. Food containing the added plant stanols as plant stanol ester were margarines and/or shortenings.Using plant stanol ester containing food products once a day reduced LDL cholesterol significantly by 9.4 % whereas using them three times a day reduced LDL cholesterol by 10.4 %. The difference between the different usage pattern was not significant. Thus effective LDL cholesterol lowering can be achieved when plant stanol ester containing products are used once a day with a meal.Plat et al. Eur J Clin Nutr 2000; 54:

N=167, baseline LDL-chol >130 mg/dl (>3,33 mmol/l), subjects had been on a stable dose of statin drug for at least 90 days. Subjects consumed either plant stanol ester spread with 3 g/d plant stanols or placebo spread (divided into 3 servings/d) for 8 weeks.At 8 weeks, plant stanol ester spread reduced LDL cholesterol by 17% compared with a 7 % reduction in the placebo group. When used together with stable statin medication, plant stanol ester was able to reduce LDL cholesterol further by 10%. That degree of reduction is somewhat greater than can be expected with doubling the dose of a statin, which generally produces an additional reduction of about 6%.Blair et al. Am J Cardiol 2000; 86:

The study by Hallikainen et Uusitupa was conducted to study whether plant stanol ester is effective as a part of a healthy, low-fat, low-cholesterol diet as well.In a parallel, double-blind, randomized study 35 hypercholesterolemic subjects were assigned after a 4-wk high-fat diet (baseline) to either a group consuming control margarine or a group consuming plant stanol ester (2.3 g plant stanol/d as plant stanol ester) containing margarine for 8 weeks. During the intervention period, all subjects consumed a diet resembling that of the National Cholesterol Education Program’s Step II diet.During run-in, subjects diet contained about 40 E% of fat and 17 E% saturated fat. During the experimental period, about 26 % of subjects’ energy came from fat and 7 % from saturated fat. This change in diet resulted in about 10 % reduction in LDL-cholesterol in the subjects using placebo spread. The LDL-cholesterol of the subjects using plant stanol ester containing spread reduced by about 24 %, of which about 14 % was plant stanol ester specific effect.The study showed that plant stanol ester effectively lowers cholesterol also as a part of a healthy cholesterol-lowering diet.Hallikainen and Uusitupa.

In this high-dose study by Gylling et al. it was first indicated that higher daily intake of plant stanols does indeed reduce LDL-cholesterol further.In this randomized, double-blind, placebo-controlled study the intervention (n=25) and control (n=24) groups consumed spread and drink enriched or not with plant stanol esters for 10 weeks.Subjects had serum total cholesterol concentrations between 4.5 to 7.5 mmol/l. Study products were 20 g/d vegetable-oil based spread and 2.5 dl/d oat-based drink containing 8.8 g/d plant stanols as plant stanol ester or placebo. Subjects were advised to continue their habitual diet, which was monitored with 3-day food records kept at baseline and at the end of the study (week 10). Fasting blood samples were taken at weeks 0,9,10 and on week 14 (4 weeks after the intervention on regular home diet).Serum LDL-cholesterol reduced by 17.1% in plant stanol ester group compared to control group.Gylling et al.

Major scientific literature databases were searched for high-quality, randomized, controlled, clinical human studies. Study inclusion and exclusion criteria were pre-defined and applied to all of the studies identified. Out of 3456 publications initially identified, 113 publications with 182 data sets met the inclusion criteria. In 137 of these data sets, plant stanols or plant sterols were administered in ester form. The data from the studies were collected individually by two investigators as double data entry ensures accuracy in the transcription of study data. Numerous statistical analyses were conducted to characterise the plant stanol (ester) and plant sterol (ester) data sets and to confirm the analytical results obtained.The meta-analysis showed that plant stanols and plant sterols do have differences in their cholesterol-lowering efficacy. The meta-analysis does not contradict previous findings that the effects of plant sterols and stanols are practically similar at the currently recommended level of 2 g/d. However, the analysis showed that the estimated maximal LDL-cholesterol reduction was 18.2% for plant stanol ester but only 9.1% for plant sterol ester. This difference in favour of plant stanol ester was statistically significant. The results demonstrated that, as the intake of plant stanol ester increased, LDL-cholesterol is reduced in a dose-dependent way. In contrast, this dose-response was not seen for plant sterols. Exclusion of high-dose studies (> 4 g plant stanols/sterols per day) from the analysis did not change the results. Additional analyses also showed that the efficacy of plant stanol ester was not affected by the fat content of the diet, or by the type of food in which it was served.Musa-Veloso et al.
