Brief Summary

Introduction:

Cardiovascular diseases have become the leading cause of death from chronic diseases in the world. One of the major risk factors for this disease is hypercholesterolemia, caused in most cases by a rich-fat diet, so came to our country Benecol ® yogurt, whose active ingredient is plant stanol ester that competes with total cholesterol and low density lipoprotein or LDL cholesterol by preventing them to be absorbed by the body and reducing blood levels.

Objective: To evaluate the efficacy of plant stanol ester in Benecol ® yogurt lowering blood lipids in moderately hypercholesterolemic patients treated at the CES Clinic during 2011.

Methods: A randomized crossover clinical trial, double-blind, placebo-controlled study in patients between 20 and 50 years with moderate hypercholesterolemia and are cared for CES control clinic in Medellin.

Expected results: Test the effectiveness of plant stanol esters in reducing total cholesterol and LDL cholesterol in patients with moderate hypercholesterolemia.

Detailed Description

The main cause of death worldwide are cardiovascular diseases, generated mainly by disturbances in the lipid profile. Several studies have shown that dyslipidemia is an important risk factor for this condition, thus maintaining the level of lipids in an appropriate range is ideal for preventing cardiovascular diseases (1)

Cardiovascular diseases are a serious epidemiological problem in the contemporary world, with approximately 17 million people die each year from causes such as myocardial infarction and stroke. The increase in cardiovascular disease and mortality attributable to them is a topic widely reported by several authors in the world. In Colombia after death from violent causes, cardiovascular diseases are on the second of the five leading causes of mortality in the general population.

Having high total cholesterol is a risk factor for the occurrence of various diseases of the circulatory system, therefore it is important to keep total cholesterol below 200 mg / dl and LDL cholesterol levels under 150 mg/dl, to avoid the accumulation of fat within the walls of the arteries that can lead to the formation of atherosclerotic plaques that cause decreased blood flow

The atlas published by WHO in 2005 provides comprehensive data on morbidity and mortality attributable to noncommunicable diseases, which are increasing. It is estimated that in 2001 approximately 60% of the 56.5 million deaths worldwide and 46% of diseases are due to noncommunicable diseases. The epidemiological burden of these diseases will increase to 57% by the year 2020. Almost 50% of deaths due to noncommunicable diseases are due to cardiovascular disease. By 2020, these diseases are responsible for 75% of all deaths worldwide.

Given the high prevalence of cardiovascular disease and dyslipidemia are considered a high risk factor for these occur, it is necessary to test the effectiveness of including the consumption of plant stanol esters in the diet to lower cholesterol values Total and LDL Cholesterol.

Arm && Interventions

Group	Intervention	Description
Benecol	assessment of efficacy of Benecol yogurt	In 2009, the dairy Cooperative Colanta Launches Benecol ® yogurt, a product with optimal daily dose of plant stanol, each portion of 100 g containing 3.4 g of Benecol ®, corresponding to 2 g of plant stanol esters . Skim yogurt with Benecol ® is a product made from pasteurized skim milk, sweetened with sucralose homogenized and fermented by the action of specific lactic culture to obtain the optimal characteristics of texture and acidity. With the addition of fruit pulp and supplemented with plant stanol esters (Benecol ®) to help reduce the risk of cardiovascular disease (31). According to Weiss et al, drinkable yogurt with Benecol ® reduces total cholesterol by 5.8% and 9.8% in LDL cholesterol (32).

Primary Outcome Measures

Name	Time	Method
Benecol Efficacy	9 weeks	Week 1: it will be taken a blood sample for lipid profile and other tests of liver and kidney function, patients will begin the Benecol ® yogurt consumption or placebo for four weeks, at week 5 it will be taken a new blood sample to perform mentioned test lipid levels and meet and determine the changes presented, patients will have a wash out week in Week 6 and groups will change for four weeks, at the end of week 9 will be held the last shot of sample for all tests again
