Cholesterol Levels and Genetics

Your family history plays a far greater role in your cholesterol levels than does your diet or lifestyle.

Diet can have a very slight (almost imperceptible) effect on your cholesterol level.  Your overall lifestyle appears to have little or no effect on cholesterol levels at all.

We still do not understand whether genetics causes high cholesterol or if environmental factors also play a role. Environmental factors include diet, smoking habits, physical activity levels, exposure to toxins, and cultural traditions.

Family History of Cholesterol

A family history of high cholesterol does not necessarily indicate that a death by heart disease is inevitable, either.


The initial research study on high cholesterol as it relates to heart disease would not hold up to today’s rigorous standards for research.  Therefore the conclusions drawn from that initial study are suspect.

More recent research indicates that diet has far less influence on cholesterol than previously believed.

Sugar intake may be a far more accurate predictor of heart disease than high cholesterol ever has been.

Sugar’s impact on Cholesterol Levels

In fact, the entire question of why we came to view a substance that is so vital to our very survival as a veritable poison is being looked at now in a different light.

Researchers today are questioning the connection between high cholesterol and inflammation.  Scientists are also re-examining the connection between high cholesterol and heart disease.

Statistics show that over half of the people who have massive heart attacks have normal LDL levels.  This brings into question the assumption that high levels of LDL cholesterol are a death sentence.

There is a well-established link between your cholesterol level and that of your parents.  We do not know yet whether that indicates a predisposition to heart disease.

There are a multitude of factors that must be taken into account before we draw any hard and fast conclusions from the data.
