[00:05.12]American researchers say a new, low-fat substitute 1 for butter could reduce the risk of heart attack and stroke 2 for millions of people.

[00:17.76]The new food product is made from vegetable oil with added substances called sterol esters.

[00:26.15]Sterols are known to reduce harmful cholesterol 3 in the blood.

[00:31.97]Harmful cholesterol increases the risk of heart attack.

[00:36.81]Cholesterol is found in meat and milk products.

[00:42.14]Sterol esters are similar in structure to cholesterol.

[00:47.12]However, sterols come from plant oils.

[00:50.73]The new,low-fat product is called Take Control.

[00:56.32]It contains sterol esters from soybeans.

[01:00.58]Take Control is one of two food products designed to reduce cholesterol.

[01:07.92]The other,called Benecol, contains plant stanol esters from the wood of pine trees.

[01:16.07]The United States Food and Drug Administration 4 approved both products last year.

[01:23.67]Earlier studies have shown that eating Benecol for several months reduces harmful cholesterol levels as much as fourteen percent.

[01:35.09]The new study involved 224 people with moderate 5 to high levels of harmful cholesterol.

[01:45.85]All the people ate a diet of lowfat,low-cholesterol foods for five weeks.

[01:53.37]One group of people ate a common low-fat product on bread and other foods.

[01:59.56]Another group ate one gram of Take Control daily.

[02:05.05]The other group ate two grams of it each day.

[02:09.75]Researchers say the harmful cholesterol levels of those who ate Take Control daily dropped more than 8%.

[02:18.11]The harmful cholesterol levels of people who had the common low-fat spread rose more than two percent
