As healthy at green tea is by itself, there's a growing body of evidence that suggests adding citrus to your daily spot will promote even greater antioxidant absorption.

Fewer than 20-percent of catechins (antioxidants found in green tea) are able to survive their passage through the small intestines. When combined with citrus -- specifically, and conveniently, lemon juice -- 78-percent of catechins were able to survive this perilous journey. Tea combined with orange juice (or drinking a glass of O.J. along with your cup of tea) kept 71-percent of catechins alive as they passed through the non-acidic environment of the small intestines.

The full study can be read in a 2007 issue of the journal Molecular Nutrition & Food Research.
