Drink green tea! You hear it everywhere. Green tea has been linked to heart health and cancer prevention, and recently even been touted as a possible way to reduce rheumatoid arthritis pain.
But as with nearly everything, too much of a good thing is not a good thing. A review of recent research found that when people ingest too much green tea -- especially in supplement form -- they run the risk of developing liver or kidney damage. Though the polyphenols in tea are beneficial in moderate doses, they can be toxic at high levels. Green tea supplements can contain 50 times more polyphenols than a single cup of green tea.
Experts say that even 10 cups of green tea a day is safe, but that if you're taking supplements you may want to watch your dose because it's easy to go overboard.
