Too much of Good cholesterol shortens your life span
Good cholesterol is good for your health. But what about excess of good cholesterol..
Researchers showed that increased levels of high-density lipoprotein (HDL) cholesterol which is called as "good cholesterol" that helps to decrease the risk of stroke and heart attack might increase a person's risk of premature death similar to low levels.
The research suggested that intermediate levels of HDL cholesterol may higher a person's long life.
Ziyad Al-Aly, Assistant Professor at Washington University School of Medicine in St. Louis, Missouri who is the study's senior author expressed that "The findings surprised us."
Al-Aly said, "Previously it was thought that raised levels of the good cholesterol were beneficial. The relationship between increased levels of HDL cholesterol and early death is unexpected."
Cholesterol is a fatty matter which is found in blood and can narrow as well as block heart vessels causing cardiovascular diseases and strokes.
For a very long duration, HDL cholesterol has been credited with helping to eliminate plaque-building "bad cholesterol" from arteries.
Researchers studied the function of kidneys in this study and HDL cholesterol levels in more than 1.7 million male veterans from- October 2003 to September 2004.
Researchers then continued to look upon the participants until September 2013. The researchers displayed that both high and low HDL cholesterol levels were associated with an increased risk of death among study participants with all levels of kidney function. This was accordingly in the study, published in the Clinical Journal of the American Society of Nephrology.
Al-Aly said, "Too low and too high are both associated with higher risk of death."
"Whether maintaining intermediate HDL cholesterol levels may increase longevity will need to be explored in future studies," Al-Aly further added.
A healthy cholesterol level would be-
Total cholesterol scores are said to be best at 200 mg/dL or below the borderline from 200-239 mg/dL, and high at 240 mg/dL or above.
HDL is proven most healthy at 60 mg/Dl and above, good between 40-50 for men and 50-59 mg/dL for women. Whereas poor is below 40 mg/dL for men and below 50 mg/dL for women.
