Cholesterol

What is cholesterol? - Cholesterol is a nutrient in our bodies that is critical for healthy cells and a healthy body.

LDL AND HDL
----
- Carrier proteins of cholesterol-

LDL (Low-density lipoproteins) = CARRIES CHOLESTEROL From liver TO THE BODY. - contributes to plague build up that clogs arteries and block blood flow which could cause a heart attack or stroke!

HDL (High-density lipoproteins)= helps get rid of ldl caught in blood stream! hdl picks up the clogged up ldl and carries it to the liver where it is broken down. This helps protect us from heart attacks and strokes.

LDL & HDL Structure & Functions differences

LDL & HDL and the risk of heart disease.

LDL structure: Contain more cholesterol than protein so they are low density.

LDL function: Binds to cholesterol in the body to carry it to the cells. Back of its low density, LDL gets stuck in blood vessels easier and causes build up.

HDL structure: Contain higher amounts of protein and lower amounts of cholesterol so they are high density.

HDL function: The high density of HDL helps it to move quicker through the blood vessels and it doesn't get stuck. Helps remove LDL build up in the blood vessels.

Doctors Monitor their patients blood pressure to watch patients LDL and HDL levels so they can make sure they are healthy and not at risk for any cardiovascular diseases.

-High cholesterol raises the risk for diseases like coronary heart disease, heart disease, heart attack and stroke.

-If too much LDL build up in your arteries it forms plague which blocks arteries and slows blood flow to the brain and heart which can cause serious heart problems or stroke.

Cholesterol tests

heartmonitron.com/hm_meddigest_journals_on_nutrition- heart_and_diabetes-cholesterol_and_healthy_weight_051.htm

Cholesterol tests will show your cholesterol in milligrams per deciliters of blood. This is done through a simple blood test.

-Doctors will find a

1. Total cholesterol

2. HDL (GOOD High density lipoproteins)

3. LDL (BAD)

4. Triglycerides (common type of fat in body)  

-Doctors will use to results to show you the risk of future heart problems or stroke risks.

Understanding your cholesterol Levels

                           WHAT THEY MEAN....

TOTAL CHOLESTEROL:

  1. Less than 200 mg = Healthy
  2. 200-239 mg = entering high risk
  3. 240 & over = Unhealthy, at high risk of heart disease.

HDL:

(MEN) - Less than 40 mg = Increased risk of heart disease

(WOMEN) - Less than 50 mg = Increased risk of heart disease

40 - 60 mg = Healthy

LDL:

1. Less than 100 mg = Healthy

2. 130-159 mg = borderline unhealthy

3. 160-189 = unhealthy

4. 190 mg & above = Extremely unhealthy, HIGH risk of heart disease.

Triglycerides:

1. Less than 150 mg = healthy

2. 150-199 mg = borderline unhealthy

3. 200-499 mg = unhealthy

4. 500 mg & above = Extremely unhealthy.

Controlling ldl & hdl levelS
***

LOWERING CHOLESTEROL:

1. Cholesterol lowering vitamins.

2. Dietary steps, take cholesterol Completely out of diet because your body already produces cholesterol naturally so you really don't need anymore.

3. Increase daily fiber intake, fibers slows the production of cholesterol

4. Weight loss, if you are over weight this can lead to higher cholesterol levels so manage your weight with a healthy diet and working out.

5. Eat Cheerios (According to a honey bee they help lower cholesterol)

Effects of FatS on cholesterol levels?
--- --- --- --- --- --- --- --- ---

Good unsaturated fats include: vegetable oils, nuts, and seeds.

- HOW DO UNSATURATED FATS AFFECT CHOLESTEROL?

*Unsaturated fats are good because they help improve healthy cholesterol levels because they increase HDL which decreases LDL.

****     

- HOW DO SATURATED FATS AFFECT CHOLESTEROL?

*Saturated fats are bad because they raise LDL in the body causing cholesterol to rise which can cause heart diseases.

*This raise of LDL in the blood stream happens because saturated fats change LDL from light lipoproteins to dense proteins which makes it easier for LDL to get stuck in the blood stream causing unhealthy cholesterol build up.

****

- HOW DOES TRANS FAT AFFECT CHOLESTEROL?

* Raises LDL and Lowers HDL.

*Eating too much trans fats raises risk of heart disease and stroke. And of course it raises the risk of having type 2 diabetes.

*Trans fat can be found in many fried foods like donuts and chicken. Also in butter, pizza, cookies etc.
