Consumption of Green or Black Tea May Positively Effect
Cardiovascular Disease by Jon M. Stout
It also affects international residents. In the U.K alone, cardiovascular disease was
responsible for over 23,000 deaths in 2004. In other words, every one (regardless of
where they live) is at risk for this potentially deadly disease.
With this in mind, researchers have been working diligently to combat this illness.
Numerous epidemiologic studies have indicated that consumption of green or black
tea reduces the risk of cardiovascular disease. However, many are left wondering
Scientists have made many assumptions about how these eas positively affects
cardiovascular disease and research is still pending. One hypothesis states that
drinking green or black tea affects lipoproteins. However, researchers have found that
drinking green or black tea does not increase the resistance of low-density lipoprotein
to oxidation in humans or the serum lipid concentrations in humans either.
Researchers determined this during a four week long parallel study comprising of 45
volunteers. The study involved the subjects drinking 900 ml (6 cups) of mineral water,
black tea, or green tea daily. Blood samples were dutifully collected from the fasting
subjects, both before and after the study. An in vitro experiment was carried out to
record the effect of adding tea extract to plasma and the consequence on the
resistance of isolated LDL to oxidation.
Data was carefully evaluated utilizing various research methodologies and researchers
concluded that the said 900 ml (6 cups) of the beverage did not have any substantial
effect on either serum lipid concentrations or resistance of LDL to oxidation. However,
It was determined that the large intake of green tea did increase the total antioxidant
activity of the plasma slightly.
Nevertheless, the arresting effect of tea flavonoids on cardiovascular disease is an
open proposition and researchers are still evaluating other probable mechanisms. For
instance, many researchers stipulate that green or black tea may have a positive
effect on the panacea and on cardiovascular disease.
Before we discuss this hypothesis further, let’s take a moment to discuss how
cardiovascular disease is triggered. In some cases, cardiovascular disease runs in
families, and in other cases it doesn’t. Many of its victims experience such triggers like
high cholesterol, raised blood pressure, and obesity. In addition, stress is thought to
contribute to this disease.
As such, physicians currently prescribe a preventive diet of fruits, vegetables, nuts,
and Omega 3 fatty acids in order to keep this disease at bay. In addition, physicians
also recommend that patients engage in regular exercise, reduce stress and anxiety
levels, and quit smoking to help prevent and keep CVD in check. In addition, drinking
black or green tea is also an important addition on the list. However, it is still unclear
the extent to which tea helps control CVD, but researchers are not giving up.
Animal and in vitro studies have suggested numerous and probable cardiovascular
protective mechanisms of tea which include prohibition of oxidized LDL cholesterol,
the disintegration of the inflammatory process in atherosclerosis, reducing
thrombosis, promotion of normal endothelial function, reduction of total plasma, and
LDL cholesterol and adhesion molecules blocking mechanisms.
In addition, the effect of tea consumption on platelet aggression shows mixed results.
A study by Duffy, et al. noted an improved endothelial function post consumption of
black tea. In addition, researchers believe that green or black tea also positively effect
endothelial function and have found that polyphenolic compounds in tea other than
catechins are responsible for improved endothelial function in humans.
Blood pressure is another area where the cardio-protective properties of tea are
believed to have a positive influence. However, studies have shown that a positive
effect is seen among subjects who had been drinking tea for at least a year, if not
more. Short-term tea drinking has not made much of a difference.

Over the years, researchers have
stipulated that green or black tea
consumption reduces the risk of
cardiovascular disease. This is
very important because people
from all walks of life inevitably
suffer from some form of this
potentially deadly disease.
According to the American Heart
Association, in 2003, there were
71,300,000 individuals that have
this disease and it claimed 910,
614 lives that year alone. This
disease does not just affect
people in the United States.
