Cholesterol patrick Harper, tanner emig

Cholesterol is a substance that has a bad reputation, but is essential for many things in the body.

Cholesterol can be used for many things such as...

  • Cell Function
  • Memory
  • Bile Acid
  • Maintain a Healthy Body
  • Cell Membrane
  • Vitamin D Production
  • Steroid Hormones


Cholesterol has two transportation systems. One which is called LDL is responsible for carrying cholesterol to all the cells in the body. The other, HDL is responsible for removing excess cholesterol from the body cells and the blood stream.

Cell Function and Cell Membrane:

Cholesterol makes the cell membrane tougher, and harder for substances to enter. The membrane allows things to pass through it into, and out of the cell, so by making the membrane tougher, unwanted outside pathogens cannot make it into the cell.

Learning and Memory:

Cholesterol helps to improve your learning and memory by allowing nerve cells to communicate with each other. This helps to improve your learning and memory by having your neurons firing more.

Digestion and Bile Acids:

Cholesterol plays a vital role in the digestion of food. Cholesterol creates bile acids that aid in the digestion of food, and allow essential vitamins and minerals to be absorbed in the small intestines and sent back out into the body through the bloodstream.

Vitamin D:

Cholesterol plays a vital role in the production of vitamin D which is an essential vitamin in the body. Vitamin D helps to make your bones sturdier, and helps with the structure of your body. When the sun shines on a form of cholesterol, it transforms into vitamin D which can be used later by the body.

Steroid Hormones:

Cholesterol helps to enhance steroid hormones in the body. Steroid hormones help regulate the immune system and helps create proteins in the body. 


LDL: LDL means low density lipoprotein

HDL: HDL means high density lipoprotein

Monitoring LDL and HDL:

Doctors monitor HDL and LDL because it helps determine your risk for heart disease. If more cholesterol was taken through the bloodstream with LDL then you have higher cholesterol but if you have more taken out with HDL then brought into the bloodstream you will have lower cholesterol. A cholesterol test can help show a patient their cholesterol levels in milligrams per deciliter in the blood.

What you can do:

To lower cholesterol you can...

  • Eat Heart Healthy Foods With Low Cholesterol
  • Exercise and Increase Activity Level
  • Lose Weight
  • Take Perscribed Medication

How Intake of Fats Affects Cholesterol...

Saturated and Trans Fat: Too much of foods high in saturated fats will cause a person's LDL levels to rise causing more cholesterol to be taken through the body. This can cause your risk for heart disease, and occluded arteries.

Unsaturated Fats: Improve cholesterol levels, and stabilize heart rhythm.

As you can see, cholesterol is not all bad, in fact it is desperately needed by the body for basic functions of life, however like most things, too much can become unhealthy and increase your risk for many heart related problems.
