The so-called "bad cholesterol " - low-density lipoprotein, commonly called LDL - may not be sobad after all, shows a Texas A&M University study that casts newlight on the cholesterol debate, particularly among adults whoexercise. Steve Riechman, a researcher in the Department of Health andKinesiology, says the study reveals that LDL is not the evil DarthVader of health it has been made out to be in recent years and thatnew attitudes need to be adopted with regard to the substance. Hiswork, with help from colleagues from the University of Pittsburgh,Kent State University, the Johns Hopkins Weight Management Centerand the Northern Ontario School of Medicine, is published in the Journal of Gerontology. Riechman and colleagues examined 52 adults from ages to 60 to 69who were in generally good health but not physically active, andnone of them were participating in a training program. The studyshowed that after fairly vigorous workouts, participants who hadgained the most muscle mass also had the highest levels of LDL(bad) cholesterol, "a very unexpected result and one that surprisedus.
"It shows that you do need a certain amount of LDL to gain moremuscle mass. There's no doubt you need both - the LDL and the HDL -and the truth is, it (cholesterol) is all good. You simply can'tremove all the 'bad' cholesterol from your body without seriousproblems occurring. Cholesterol is found in all humans and is a type of fat around thebody.
A person's total cholesterol level is comprised of LDL(low-density lipoprotein) and HDL (high-density lipoprotein)cholesterol. LDL is almost always referred to as the "bad" cholesterol becauseit tends to build up in the walls of arteries, causing a slowing ofthe blood flow which often leads to heart disease and heart attacks . HDL, usually called the "good cholesterol," often helps removecholesterol from arteries. "But here is where people tend to get things wrong," Riechman says.
"LDL serves a very useful purpose. It acts as a warning sign thatsomething is wrong and it signals the body to these warning signs.It does its job the way it is supposed to. "People often say, 'I want to get rid of all my bad (LDL)cholesterol,' but the fact is, if you did so, you would die," theTexas A&M professor adds. "Everyone needs a certain amount of bothLDL and HDL in their bodies. We need to change this idea of LDLalways being the evil thing - we all need it, and we need it to doits job." According to the American Heart Association, about 36 millionAmerican adults have high cholesterol levels.
"Our tissues need cholesterol, and LDL delivers it," he notes."HDL, the good cholesterol, cleans up after the repair is done. Andthe more LDL you have in your blood, the better you are able tobuild muscle during resistance training." Riechman says the study could be helpful in looking at a conditioncalled sarcopenia, which is muscle loss due to aging. Previousstudies show muscle is usually lost at a rate of 5 percent perdecade after the age of 40, a huge concern since muscle mass is themajor determinant of physical strength. After the age of 60, theprevalence of moderate to severe sarcopenia is found in about 65percent of all men and about 30 percent of all women, and itaccounts for more than $18 billion of health care costs in theUnited States. "The bottom line is that LDL - the bad cholesterol - serves as areminder that something is wrong and we need to find out what itis," Riechman says.
"It gives us warning signs. Is smoking the problem, is it diet, isit lack of exercise that a person's cholesterol is too high? Itplays a very useful role, does the job it was intended to do, andwe need to back off by always calling it 'bad' cholesterol becauseit is not totally bad."
