Although high caffeine intake is reportedly a risk factor for reduced bone mineral density (BMD), a study published in the
American Journal of Clinical Nutrition
found that older women who drank tea actually had higher bone mineral
density (BMD) measurements than women who did not drink tea. Depending
on the tea blend and brew strength, tea (with approximately 40mg. per
serving) contains, on average, less than half the caffeine of coffee.
Cardiovascular Health
Research presented at the American College of Cardiology 50th Annual Scientific Session revealed:
- A combined analysis of 13 published studies found an average
estimated 11 percent lower rate of heart attacks among study
participants who drank three or more cups of tea per day. According to
the researcher, Dr. Lenore Arab of the University of North Carolina at
Chapel Hill, that 11 percent could translate to a potential preventive
impact for 100,000-110,000 people were all persons at risk to increase
their intakes by 3 cups/day. This estimate is based on an average
number of 1.1 million heart attacks per year in the United States.
- A study involving people diagnosed with coronary artery disease
reported that subjects who drank four cups of black tea per day showed
improved blood vessel function. These results suggest that drinking tea
may improve an important underlying abnormality of blood vessel
function that may be related to coronary artery disease.
Fluid BalanceFor millions of people, drinking tea plays a significant role in
maintaining fluid balance, which is crucial for normal body function.
Water is a major component of all living matter requiring continual
replenishment. Water keeps the body cool, transports nutrients, and
cushions joints. Most adults need about two quarts of fluid daily which
should come from beverages and some fruits and vegetables.
Oral HealthDrinking one cup of tea a day-either black or green-may contribute to
oral health. Some experts believe that the flavonoids in tea may
inhibit the plaque-forming ability of oral bacteria and that tea's
naturally occurring fluoride may support healthy tooth enamel.
