A Healthy Heart
A "healthy heart", or really cardiovascular system, means that the
heart muscle itself is powerful. It also means the blood vessels have good integrity,
are clear, and pliable. Heart attacks occur for many reasons, primarily due to
a change in these conditions. The most common changes are blood vessels becoming
blocked with the buildup of plaque and artery walls becoming hardened, stiff,
and weak.
What causes these changes? The most popular theory
is that cholesterol builds up inside the artery walls
causing them to become less pliable and narrowed
by plaque. A piece of plaque may break off and flow
into a smaller vessel, blocking it. If this occurs
in a coronary vessel, a heart attack occurs. If this
occurs in a vessel in the brain, it results in a
stroke.
The misconception is that the culprit of these
processes is cholesterol. Actually cholesterol accounts
for only a small percentage of the substances that
make up arterial plaque. The idea that heart attacks
were caused high cholesterol and dietary fat intake
was popularized before adequate evidence was collected
to support it. To this date, evidence is still lacking,
yet the hypothesis is used to make dietary recommendations
and support the use of cholesterol lowering medications.

Myths |

Cholesterol is actually a crucial
substance in the body. Cholesterol is the
backbone for all other steroidal hormones
such as estrogens, progesterone, DHEA, Cortisol,and
testosterone. Thus, issues of sexual dysfunction
and hormonal imbalance are often increased
by our efforts to reduce cholesterol levels.
Cholesterol is necessary for fat metabolism
and for proper brain function and neurotransmitter
activity (such as serotonin - the "feel
good" brain chemical). Decreased cholesterol
and a low fat diet are strongly correlated
with Alzheimer's disease. Cholesterol is also
an important part of every cell membrane. It
makes cell membranes elastic and pliable. Without
enough cholesterol, cell membranes become rigid
and more likely to crack and leak. Decreased
cholesterol can therefore impact the function
of every cell in the body and therefore every
process in the body.
If you would like to see the research for
yourself, I highly recommend the book The Cholesterol
Myths by Uffe Ravnskov, MD, PhD. He provides
a thorough account of numerous cholesterol
studies, illustrating how the conclusions drawn
from these studies are questionable and, in
some cases, completely contrary to what the
data show. Follow this link to see a short
list of some facts about cholesterol and the
human body.

| Vitamin
C complex, with its rutin and flavonoids intact,
is critical to the strength, integrity, and
proper elasticity of blood vessel walls. Studies
have linked low blood levels of vitamin C to
weakness, tearing and chronic inflammation
of arterial walls, and to an increased risk
of heart attack.
Deficiencies of B vitamins are related
to hardening of arteries, the degree of
plaque buildup, and diminished nerve function
that adversely affects the vessels' ability
to constrict and dilate appropriately.
Taking a good quality B vitamin may be
important for many people. Even more important
is looking at factors that deplete the
body of B vitamins. The main culprit is
refined food - primarily white sugar and
white flour.
Other vitamins like vitamin A & D,
plant phytochemicals such as flavonoids,
co-enzymes such as coenzyme Q-10, and minerals
such as magnesium, potassium, calcium,
selenium, copper, zinc and others are crucial
elements in protecting blood vessels and
cardiac muscle. Coenzyme Q-10 specifically
is essential for production and transportation
of energy in the heart. Co-Q10 is depleted
by cholesterol lowering drugs.
Before we think about supplementing with
these nutrients, it is first important
to change dietary habits that deplete the
body of these essential, heart-saving nutrients.
In the simplest terms this means eating
whole un-adulterated foods as much as possible,
and eating processed food (white flour
and sugar, refined oils, and highly processed
food products) as little as possible. Coronary
artery disease is half as frequent in people
with high intakes of fresh fruits and vegetables.

The
herb hawthorn is the premier cardiac tonic.
It strengthens the contraction of the heart
muscle, normalizes blood pressure, increases
vascular integrity, and prevents free-
radical damage. Hawthorn is also anti-inflammatory
- addressing heart disease at its very
source.
My Sweet Heart-Ease Tea is made of hawthorn
and the sweet green leaf of stevia. Whole
stevia leaf is believed to aid in blood-sugar
regulation and to have an anti-hypertensive
action. It adds a sweet taste and, unlike
refined sweeteners, is safe for most diabetics.

The
Truth About Cholesterol |
|
|
The words "high
cholesterol" have become synonymous
with "high
risk for heart attack".
Correspondingly the phrase "low cholesterol" is
associated with safety from heart disease.
Actually, both of the above statements
are absolutely false. In this bulletin, I
provide some simple guidance for understanding
heart health and some clarity on the issue
of cholesterol.
While the information I can provide here
is limited by space, I have also included
links to resources if you want further information. |
