a lot of anything is bad.how much do you consider a lot?

I don't know but I go through about 10-12 cups a day. It is a lot better for me though than what I used to drink lol!

Too much of anything can have ill effects. So yes too much tea can do more harm than good.

HI! Tea has a lot of good antioxidants in it, but it is also a diuretic (dehydrates you and makes you pee)also if not decaf has more caffiene than coffee. So it's ok but you want to not over indulge.

Tea is a diuretic, which means it dehydrates you. It also contains caffeine, which isn't great for you. It's really bad for you if you're putting a lot of sugar in your tea. That said, there are a lot of good things in tea, also. So my suggestion is in all things moderation, drink enough water to counterbalance the tea, and make sure you're not overdoing the sugar.

Tea can be very good for you but it will make you pee and there may be a lot of caffeine if you drink A LOT!

I drink nothing but tea, and I still live. And that's really not an exaderation - it's very, very rare that I ever, ever drink anything else.

I'd say so...It contains caffeine and with the milk it's extra calories so maybe drink water instead- the healthier option...

anything in excess is bad for you.

EVERYONE WHO SAYS TEA IS A DIURETIC IS WRONG! It isn't the tea itself that is the diuretic. It's the CAFFEINE contained in the tea that is the diuretic. And caffeine in extremely excessive amounts can dehydrate you to the point of constipation when you are attempting a bowel movement. And tea isn't the only thing that has caffeine. It's found in higher amounts in soda.

Too much tea cannot be good for you however, enough of it can, I think... :-)

Generally, tea is good for you. But, like all things you ccan have too much of a good thing.

I have heard it is. But can't be half as bad as drinking too much coffee which definitely is bad

Tea contains oxalates, which can contribute to kidney stones..

"Potential drawbacks - Effects of fluoride All tea leaves contain fluoride; however, mature leaves contain as much as 10 to 20 times the fluoride levels of young leaves from the same plant. In general, the level of fluoride in tea is inversely related to the EGCG contents: the more EGCG, the less fluoride. White tea contains less fluoride than green tea and black tea, because it is made of buds and young leaves only. The fluoride content of tea depends directly on soil and air pollution; tea plants absorbs this element at a greater rate than other plants. Care in the choice of the location where the plant is grown may reduce the risk. According to Andreas Schuld of the Canadian Parents of Fluoride Poisoned Children, tea is very high in fluoride content, much higher than the Maximum Contaminant Level (MCL) set for fluoride in drinking water. Decaffeinated teas have an even higher fluoride content, which is thought to be due to high fluoride levels in the water used in decaffeination. According to Schuld, fluoride could reduce the anti-cancer properties of tea, or even possibly cause cancer at continued toxic levels of the mineral. For instance, Schuld references a 1998 study which found positive correlation between colon cancer and tea intake. The high fluoride content could also cause neurological and renal damage, especially in the presence of aluminum. Additionally, the high fluoride content could cause osteoporosis, arthritis, skeletal fluorosis and other bone disorders. Cancers of the digestive tract, which have a higher incidence in Far East countries, have manifold environmental causes and cannot be blamed solely in those peoples' habit of consuming tea. - Effects associated with caffeine Caffeine is an addictive substance and overuse of tea can result in harmful side effects, such as an increased likelihood of certain sleep disorders. Decaffeination reduces total catechins in both black and green dry teas by about 15 times and 3 times respectively. - Oxalates Tea contains oxalate, overconsumption of which can cause kidney damage, as well as soak up free calcium in the body; other minerals could be soaked up as well. The bioavailability of oxalate from tea is low and because of this a negative effect requires large amounts of tea. - Tannin It has been suggested that the chemical known as tannin may increase the risk of nasal and esophogeal cancer. However, some studies have found tea drinking might be negatively associated with risk of esophageal cancer."
