A new study of researchers is giving good news for Americans with their conclusions revealing improvement in the cholesterol levels of US adults but cardiologists insists that still there is a need for the people to stay focused upon their health and involve in measures that can improve it.

Above findings are the result of a recently ran survey in which experts studied health of more than 3,500 men and women. They noticed that the total cholesterol levels among all the U. S. adults have decreased by approx 10 points in last two decades i. e. from an average of 206 to 196 mg/dL.

Also, they noticed a 13-point drop in low-density lipoprotein cholesterol, which is commonly known as LDL or "bad" cholesterol. The group of those surveyed included people of all age, both genders, different races along with the ones suffering from obesity and those adults, who had never taken cholesterol-lowering medications.

"These findings are important because individuals with high levels of total or `bad' cholesterol have a greater chance of developing heart disease, one of the leading causes of death in the United States," said lead author Mr. Margaret Carroll, a survey statistician at the National Center for Health Statistics at the Centers for Disease Control and Prevention in Hyattsville, Md.

But they continue insisting to take care of health.
