Equal Exchange fairly traded teas are grown by small-scale farming communities around the world. These farmers practice sustainable agriculture, which means no nasty pesticides. This improves soil and water quality, and the farmers' overall health. Drinking organic tea, and particularly green tea, can have many health benefits for you and your family. Let's take a closer look at the health benefits of green tea:

  • Heart Health. Research links tea to its impact on heart health. Green tea contains flavonoids that prevent oxidation of LDL (bad) cholesterol, decrease blood clotting and increase vasodilation (widening of blood vessels). A study found that women who drink three to five cups of green tea a day had a 31 percent decreased risk of dying of heart disease.
  • Cancer. A recent analysis of 25 studies showed that green tea consumption decreased colon cancer by 18 percent and breast cancer by 20 percent.
  • Dental Health. Fluoride in the water used to brew tea and fluoride found in tea leaves (accumulated from healthy soil), alongside antibacterial catechins in tea create an anti-cavity effect. One cup of green tea per day may decrease the odds of tooth loss.
  • Bone health. Fluoride and photo-estrogens in tea promote bone health. A study found that four cups a day can increase the mineral content of bones.
  • Mood. A 2012 study found that tea increased productivity, mental health and improved mood, as the L-theanine in green tea increases relaxation and neutralizes the caffeine effect.
  • Aging. A 2012 study showed promise that green tea can decrease the aging process, as the large quantity of polyphenols decrease the damage done by oxygen to DNA. Green tea drinkers were less likely to have psychological distress, strokes, heart attack, and liver disease and more likely to have a better diet, greater cognitive activity, and greater community participation.
  • Hydration. Up to eight cups of tea per day count toward hydration.

Please note: Tea should never replace a balanced diet, but can enhance a nutrient-rich diet. Tea benefits are strongest when tea is brewed correctly and when the addition of sugar, milk, etc. is limited.
