Healthful Benefits of Tea
In ancient China, tea was considered
an elixir and initially consumed for its perceived medicinal properties.
Today, more and more scientific evidence contributes to the belief
that tea, indeed, is a healthy beverage. The following provides
a summary of the health benefits associated with tea:
Cancer Prevention
- All tea contains flavonoids, which act as antioxidants that help
protect the cells of the body against damage caused by free radicals.
Free radicals form naturally as a result of chemical reactions during
normal cellular activity and contribute to tissue damage over time.
Laboratory and animal studies have demonstrated that tea flavonoids
can block the action of enzymes that cancers need for growth and
can deactivate substances that promote the growth of cancers. Some,
but not all, studies in people have shown a connection between drinking
tea (especially green tea) and lower rates of cancer.
Heart Health
- A number of recent studies suggest that tea may help to decrease
the incidence of heart attack by reducing cholesterol in the blood,
improving the function of blood vessels and inhibiting inflammation
that can contribute to atherosclerosis.
Oral Health
- Several studies have suggested that regular tea drinking may reduce
the number of dental cavities, partly as a result of its high fluoride
content. Tea has also been shown to increase the acid resistance
of tooth enamel and to help prevent harmful bacteria from sticking
to the teeth.
Bone Health
- A study conducted in Taiwan showed that habitual tea consumption
for more than a decade increased total bone mineral density in both
men and women. Additionally, a study among older women has linked
tea to greater bone density and a lower risk of hip fractures.
Gastrointestinal Health
- Long-term tea drinking may flush out bacteria that aren't so good
for the digestive system and could allow more helpful ones to flourish.
