Science-Backed Benefits of Coffee:
- Heart: Based on 36 different studies with 1,270,000 participants, researchers conclude moderate long-term coffee consumption of three to five 8-ounce cups a day lowers the risk of cardiovascular disease. Those who consumed five or more had no higher risk than those who consumed zero.
- Stroke: Another 11 studies with nearly 480,000 participants found two to six cups a day was associated with a lower risk of stroke compared to those who drank zero.
- Type 2 Diabetes: Drinking at least six to seven cups of caffeinated and decaffeinated coffee a day was found to reduce the risk of type 2 diabetes by up to a third, while regular consumption decreased the overall likelihood of developing the disease.
- Cancer: Drinking two cups of coffee day is associated with a 40 percent lower risk of liver cancer. Coffee consumption also plays no statistical significance in breast or prostate cancer risk. There is a link between coffee consumption and lung cancer, but only found among those who have the disease due to smoking. Meanwhile, coffee consumption has actually been found as a protectant for non-smokers diagnosed with lung cancer. Coffee has been found to lower the risk of liver cancer and death for those who have cirrhosis.
- Brain: Coffee intake has been associated with lowering the risk of Parkinson’s disease, age-related cognitive decline, and a potential protective effect against Alzheimer’s disease.
- Death: Two meta-analysis — one reviewing 20 studies with approximately one million participants’ medical data and a second reviewed 17 studies with more than one million participants — found drinking coffee is linked to a “significantly reduced chance of death.”
