What You Should Know About Tea

Over at the Precision Nutrition forums (Precision Nutrition is John Barardi's company), there is a great article on tea by Ryan Andrews, containing just about everything there is to know, from preparation to benefits. Check it out.

Here is a bit of the article:

The Benefits of Regular Tea Consumption
Now, let’s outline some of the benefits attributed to regular tea consumption.

Note: These benefits were outlined at the 2007 "Tea and Health" symposium, a conference in which tea researchers world-wide got together and provided some definitive answers on what tea does and what it doesn't do - at least, according to what we know today.

We'll list these benefits by category...

Tea and body composition

• Green tea increased 24-hour energy expenditure and fat oxidation
• 3-months of tea consumption decreased waist circumference by 4.5%

Tea and cardiovascular health

• Tea increased lipid oxidation
• Tea improved blood vessel function
• Those who consumed 3 or more cups of black tea per day had a reduced risk of heart disease and stroke
• Drinking 6 or more cups of black tea per day was associated with decreased serum cholesterol and triglycerides
• Those who drank a cup or more of black tea daily had a 44% reduction in the risk of heart attack compared to non-tea drinkers
• Those who consumed tea during the year prior to a heart attack were up to 44% more likely to survive following the cardiac event
• Japanese men and women who consumed just over 2 cups of green tea per day reduced their risk of death from cardiovascular disease by 22 - 33%
• 5 cups of black tea per day reduced LDL cholesterol by 11% and total cholesterol by 6.5% compared to placebo beverages
• Those who consumed 4 cups of tea per day had a 69% lower risk of atherosclerosis
• Tea restored blood vessel function in those with coronary artery disease
• Tea helped to prevent atherosclerosis
• Tea enhanced dilation of blood vessels

• Tea assisted in the regression of oral cancer
• Tea drinkers had decreased ovarian cancer risk

Tea and immune function

• Tea boosted natural resistance to microbial infection

Tea and oral health

• Tea inhibited the plaque forming ability of oral bacteria

Tea and bone health

• Although caffeine intake has been suggested to be a risk factor for reduced bone mineral density, research indicated that drinking tea does not negatively affect bone mineral density
• Older women who drank tea had a higher bone mineral density than those who did not drink tea

Tea and kidney stones

• Those who drank tea had a lower risk of developing kidney stones

Tea and neurological decline

• Drinking tea resulted in a reduced risk of Parkinsons disease

Tea and spouse selection

• Those who drank 5 cups of green tea each day had a more attractive spouse (are you still paying attention to my article? This one has yet to be confirmed by research - but you never know).
