The health impact of coffee has long been a controversial topic, with advocates touting its antioxidant activity and brain-boosting ability, and detractors detailing downsides such as insomnia, indigestion and an increased heart rate and blood pressure.


Health benefits of Coffee:

  • Blood pressure. Results from long-term studies are showing that coffee may not increase the risk for high blood pressure over time, as previously thought. Study findings for other cardiovascular effects are a mixed bag.
  • Cancer. Coffee might have anti-cancer properties. Last year, researchers found that coffee drinkers were 50% less likely to get liver cancer than nondrinkers. A few studies have found ties to lower rates of colon, breast, and rectal cancers.
  • Cholesterol. Two substances in coffee — kahweol and cafestol — raise cholesterol levels. Paper filters capture these substances, but that doesn’t help the many people who now drink non-filtered coffee drinks, such as lattes. Researchers have also found a link between cholesterol increases and decaffeinated coffee, possibly because of the type of bean used to make certain decaffeinated coffees.
  • Diabetes. Heavy coffee drinkers may be half as likely to get diabetes as light drinkers or nondrinkers. Coffee may contain chemicals that lower blood sugar. A coffee habit may also increase your resting metabolism rate, which could help keep diabetes at bay.
  • Parkinson’s disease. Coffee seems to protect men, but not women, against Parkinson’s disease. One possible explanation for the sex difference may be that estrogen and caffeine need the same enzymes to be metabolized, and estrogen captures those enzymes.

Caffeine is the main component of coffee. Average caffeine content in various types of coffee is as follows:

Drip coffee-115-175mg
Decaf, instant-2-3mg
Decaf, brewed-3-4mg


Dosage on drinking Coffee:

  • 2-3 cups of coffee a day.


Nutrients you can get in Coffee:

Coffee is rich in magnesium and chromium. Magnesium only constitutes 0.05 percent of body weight, but it is an extremely important macromineral. It is involved in hundreds of enzymatic reactions, including those responsible for cardiovascular function and energy production. Chromium is an essential mineral that the body needs for good health.
