Check out the highlights of scientific research and evidence of coffee’s unique health benefits related to:
SCIENCE: In a review of 21 prospective studies totaling over 10 million participants, drinking one cup of coffee (whether decaf or with caffeine) per day was associated with a 3% reduced risk of death, and drinking 3 cups of coffee was associated with a 13% reduced risk of death.
SCIENCE: A study from the International Agency for Research on Cancer (IARC) looked at over 500,000 people, and found that drinking coffee, whether decaf or with caffeine, was associated with reduced risk for death from various causes.
SCIENCE: A study of over 500,000 people, spanning a decade, found that drinking coffee, whether caffeinated or decafeinated, was inversely associated with mortality, including among those drinking 8 or more cups per day.
SCIENCE: In a large study looking at over 400,000 people, coffee consumption was associated with lower likelyhood of death from disease.
SCIENCE: A meta analysis of human prospective studies showed that drinking both caffeinated and decaffeinated coffee was associated with reduced risk of liver cancer.

SCIENCE: Coffee consumption may offer protective benefits for post-menopausal breast cancer. Consumption of four cups per day was associated with a 10% reduction in postmenopausal cancer risk.
SCIENCE: Coffee drinking is associated with a lower risk of colon cancer in women. A study showed that there was a 20% reduced risk of colon cancer in women who drank more htan 3 cups of coffee day, compared to those who drank less than one or less.

SCIENCE: Drinking coffee may prevent recurrence of liver cancer in adults
SCIENCE: Studies show that coffee drinkers are at a lower risk of developing Type 2 diabetes, which accounts for 90-95% of diabetes cases in the world. They also show that people who drink four or more cups of coffee daily have a 50% lower risk of Type 2 diabetes.

SCIENCE: The results of a survey looking at over 83,000 women over many years showed that coffee consumption may modestly reduce the risk of stroke among women.
SCIENCE: A study from the International Agency for Research on Cancer looked at over 500,000 people, and found that coffee drinking was associated with reduced risk for death from various causes, including stroke.
SCIENCE: A large-scale study in Japan found that higher green tea and coffee consumption was inversely associated with risk of CVD and stroke in the general population.
SCIENCE: Coffee consumption is associated with reduced risk of chronic kidney disease.
SCIENCE: An independant meta-analysis found that coffee consumption is associated with a reduced risk of depression.
