A study done at Purdue University found that a squeeze of citrus juice in a cup of green tea significantly increased the absorption of tea’s catechins. Catechins are the antioxidants found in tea that may help battle cancer cells.  When drinking green tea on its own, your body absorbs about 20% of the catechins. But, if you squeeze in a bit of lemon juice, that absorption level jumps to 80%! So enjoy your cup ‘o tea with a squirt of citrus.
