Good Cholesterol Vs. Bad Cholesterol

Temple Fit Episode #33, Date Aired 4/23/2014
“Good Cholesterol vs. Bad Cholesterol”

We are continuing the theme “Good Vs. Bad”. In Proverbs 4:23, we are instructed, “Guard your heart above all else, for it determines the course of your life.” With that, today, we’re discussing good cholesterol vs. bad cholesterol.

Understanding What Cholesterol Is
Cholesterol is not a nutrient like carbohydrates. As the National Heart, Lung, and Blood Institute puts it, “Cholesterol is a waxy, fat-like substance that’s found in all cells of the body.” The main purpose of cholesterol is to help make hormones, aid in food digestion, and help in making Vitamin D. 
The body can make cholesterol itself.  Cholesterol is also in the animal foods we eat—meat, dairy products, eggs, etc.
The Good and the Bad of the Matter
Cholesterol travels throughout the body in packages called lipoproteins.  This package is exactly as it sounds: it’s lipid (fat) on the inside, and a protein casing on the outside.


Focus is placed on two types of lipoproteins: 

Low density lipoproteins, called the “bad” cholesterol;  

and High density lipoproteins, called the “good” cholesterol.

1.Low density Lipoproteins (LDL’s)– Have a lower amount of PROTEINS in them, compared to having a higher amount of cholesterol. Their job is to transport the cholesterol in the blood to the cells. 
High LDL cholesterol levels lead to plaque build up on artery walls (Image: CDC)

If you have high levels of LDL’s in the body—transporting more cholesterol than the cells need—the excess can can build up along the artery walls. Plaquing of the artery walls can lead to heart diseases such as atherosclerosis, hypertension, heart attack, and stroke.
Figure A shows the location of the heart in the body. Figure B shows a normal coronary artery with normal blood flow. The inset image shows a cross-section of a normal coronary artery. Figure C shows a coronary artery narrowed by plaque. The buildup of plaque limits the flow of oxygen-rich blood through the artery. The inset image shows a cross-section of the plaque-narrowed artery.

2.High density lipoproteins (HDL’s)– Have a higher amount of PROTEINS in them, compared to having a lower amount of cholesterol.  Their job is to transport cholesterol in the blood to liver, so the the liver can remove the cholesterol from the body.  
Higher amounts of HDL are preferred, because this aides in the clearing away the cholesterol that is not being used optimally by the body…therefore protecting us against heart diseases.
How can you increase the amount of good cholesterol in your temple?  
  • Regular physical activity. >>>150 minutes of moderate-intensity every week
  • Reduce bad fats. >>> brush up on good fats vs. bad fats here
  • Eat a balanced, nutritious diet
  • Stop smoking. >>>Cigarette smoking can decrease HDL’s, so not smoking will improve your HDL levels.
