Cholesterol Explained

We've all been told to keep our cholesterol down, because high cholesterol leads to hardened arteries, coronary heart disease and even strokes.

However, cholesterol gets a bad rap.  Unwanted and unloved, the waxy compound earns its reputation from the company it keeps.  On its own, cholesterol is quite handy around the body.  It helps form cell membranes and it is crucial for growth in babies.

A cholesterol molecule is a lipid, which is a category of water-insoluble substances such as waxes, oils and fats.  Because it can't dissolve in water or watery substances like blood, cholesterol can't move around in the bloodstream on its own.  It has to catch a ride.

In order to travel around the body, cholesterol combines with protein, forming a lipoprotein.  The protein actually coats the cholesterol.  However, not all lipoproteins are created equal.

When the lipoprotein has more protein than cholesterol, it resembles a Ferrari, gunning through your body without stopping until the cholesterol arrives at your liver, where it is converted into bile acids.  These Ferraris are high-density lipoproteins (HDLs), which most of us just call "good" cholesterol.

When the lipoprotein has more cholesterol than protein, however, this makes for a rickety ride, and that jalopy doesn't get too far.  Cells have special receptors that bind tightly to these lipoproteins as they pass.  This low-density lipoprotein (LDL), or "bad" cholesterol, sputters down the road, careening off the arteries, running into things and leaving bits all over the place.

While the HDL Ferrari sees a pileup and nimbly speeds around it, the LDL jalopy crashes right into it, adding to the jumble of tangled fenders and tailpipes (or platelets and plaque).

The HDLs actually are kind enough to offer a lift to any stray LDLs they encounter.  The problem is that our levels of HDLs and LDLs get out of whack.  There are more crazy LDLs lurking around than there are responsible HDLs to pick them up.

HDL and LDL cholesterol Another Benefit of Seven Essentials ... Improve Cholesterol!

Seven Essentials contains RiSoTriene which reduces the adherence of cholesterol plaque to arterial walls, allowing them to be more flexible and less prone to high blood pressure.  The components found in RiSoTriene, such as Gamma Oryzanol, Phytosterols (including beta sistosterol), Inositol and Omega-3, work to lower LDLs (bad cholesterol) while raising HDLs (good cholesterol).

What is blood pressure?

Blood is carried from the heart to all body parts in arteries. As blood is pumped through the body, it exerts pressure on the artery walls. This is blood pressure. It is given as two numbers, for example, 120 over 80. Normal blood pressure readings are in the range of 120/80.

Systolic Blood Pressure:

The top number represents the pressure against the walls of the arteries when the heart contracts.

Diastolic Blood Pressure:

The bottom number represents the pressure against the artery walls when the heart relaxes.
