What role it plays in the body Where does it come from Not LDL or HDL or Triglyceride Comparison of types of Lipoproteins

Lipid Panel: What is measured What can be done Naturally What Statin Drugs do


What are we afraid of? 

Cholesterol:  A fatty waxy

substance

http://medicalmyths.wordpress.com/atherosclerosis/


Polarized light


Between artery layers


What it is According

to Toshihide Kobayashi, Chief Scientist at the RIKEN Advanced Science Institute, “People think cholesterol is bad for health. But without cholesterol, we could not survive…”


What Cholesterol does in the body      

Holds cell together Cell communication Fluidity of cell membrane Holds proteins in place Protects Nerve Fibers Vitamin D

Needed to make steroid hormones Testosterone Estrogen Needed to make bile


Forms our cells

Kobayashi ď‚ž

“Because cholesterol is of paramount importance to the human body, there is no mechanism for its degradation. Hence, excess cholesterol must be discharged from the body mainly through the excretion of bile salts. The body has long evolved to acquire cholesterol, and it is only in the past few decades of people eating too much food that the intake of cholesterol has become excessive and a problem.�


Poor choices… Atherosclerosis  Diabetes  Heart Disease….. 


The choice is up to you.... Sick, sluggish cells

Healthy, vibrant cells


Cholesterol 

NOT LDL or HDL  

  

Low Density ____________? High Density ____________?

LIPO = LIPID= FAT PROTEIN=PROTEIN LIPOPROTEINS −

Transport Cholesterol


Lipoprotein • The cholesterol is all the same It is just cholesterol • Like people in vehicles • People in small cars are “good”, but people in all the others are “bad”

• • • • • •

HDL LDL IDL VLDL Chylomicrons They all TRANSPORT Cholesterol


Kinds of Lipoproteins


Lipid Panel LDL HDL Total Cholesterol Triglycerides But why NOT

• • • • • • •

IDL VLDL


LDL “Bad” Small LDL 

 

Causes atherosclerosis Stuck: oxidized/damag ed Inflammation Foam Cell/ Macrophage

Large buoyant LDL  Don't get stuck in arteries  Carry cholesterol to rebuild cells (damage, inflammation)  If you don't have enough cholesterol, you can't reform healthy cells 


HDL “good”   

Helps reduce build-up of Small LDL High # lower levels of heart disease. Takes the Cholesterol back to the liver, so it can be used again….

Will Not make foam cell


Triglycerides • • •

Not cholesterol Contribute to atherosclerosis Excess Calories become Triglyceride – – – –

Amino Acids from Protein Sugar/ Carbohydrates Fat Alcohol


Is your body trying to kill itself?  

Glucose is much more damaging Body wants contents to be the least damaging to cells (triglycerides) Why persons with high blood sugar almost always have high triglycerides.


Where Cholesterol comes from •

From animal products, not plants –

Fatty acids • •

Saturated fats Trans fats

Body makes it −

Nature wouldn't create a substance that ultimately destroy us


Franklin Institute 

By modifying natural fats, we have altered the basic building blocks of the human brain – weakening the brain’s architecture. And, like unstable buildings that come apart in an earthquake or storm, poorly structured human brains are failing to cope with the mounting stress of modern life

Modified Fats… 

Hydrogenated Fats  Partially of Fully  Be careful of labels ○ Trans Fats  Raise LDL and decreases HDL  Affect cell membrane


What statin drugs do Lipitor, Mevacor, Zocor, Lescol, Pravachol, −Baycol taken off the market because people died.  

"cholesterol-lowering" Inhibit pathways 

Only one?


What changes could you make?? 1. 2. 3. 4. 5.


What can be done naturally 

Eat Right −

Oatmeal 

− − − −

Less processed the better

Whole grains Nuts, esp. almonds Olive Oil Vegetables 

Not overcooked


 

  

Exercise Must raise heart rate to ideal level for _____ minutes. Sleep Lose body fat Quit Smoking


Supplements  Omega 3 Fish oils  Red Yeast Rice 

 what Statin drugs are made from!

No Flush Niacin  Spices 

LDL readily enters the artery wall by crossing the endothelial membrane. Once in the arterial wall, if LDL accumulates, it is subject to a variety of modifications. The best known of these is oxidation, both of the lipids and of the apo B. LDL is also subject to aggregation, and its phospholipids are subject to hydrolysis by phospholipases to form lysophosphatidylcholine. Several other chemical modifications have also been reported. The net effect of these changes is

Dolichols (mevalonate inhibition)  Neuropeptide dysfunction  Thought, Sensory, Emotional Disturbance  Decreased cell signaling

Mevalonate  Glial Cell

Inhibit Co-Q10  Helps to make energy in cells  Co-Q 10 helps decrease LDL oxidation!

Cholesterol is transported in the plasma predominantly as cholesteryl esters associated with lipoproteins. Dietary cholesterol is transported from the small intestine to the liver within chylomicrons. Cholesterol synthesized by the liver, as well as any dietary cholesterol in the liver that exceeds hepatic needs, is transported in the serum within LDLs. The liver synthesizes VLDLs when the body is getting too much fatty acids. and these are converted to LDLs
