Low-density lipoprotein (LDL) – popularly known as bad cholesterol – turns out to be critical for building muscle mass, and lowering of the body’s LDL levels can cause serious health problems, say researchers at Texas A&M University in a new study.
Researcher Steve Riechman said the study reveals that LDL is not the evil Darth Vader of health it has been made out to be in recent years. His findings, published in the Journal of Gerontology, were gleaned from subjects aged 60 to 69 who were in generally good health but not physically active. The study showed that after fairly vigorous workouts, participants who had gained the most muscle mass also had the highest levels of LDL.
This, according to Riechman was; “a very unexpected result and one that surprised us. It shows that you do need a certain amount of LDL to gain more muscle 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’t remove all the ‘bad’ cholesterol from your body without serious problems occurring.”
LDL is called “bad” cholesterol because it tends to build up in the walls of arteries, causing a slowing of the blood flow which often leads to heart disease and heart attacks. “But here is where people tend to get things wrong,” Riechman says. “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.”
“It plays a very useful role, does the job it was intended to do, and we need to back off by always calling it ‘bad’ cholesterol because it is not totally bad,” he concluded.
