1. Coffee is a potent source of healthful antioxidants.
In fact, coffee shows more antioxidant activity than green tea and cocoa, two antioxidant superstars. Scientists have identified approximately 1,000 antioxidants in unprocessed coffee beans, and hundreds more develop during the roasting process. Numerous studies have cited coffee as a major — and in some cases, the primary — dietary source of antioxidants for its subjects.
2. Caffeine provides a short-term memory boost.
When a group of volunteers received a dose of 100 milligrams (mg) of caffeine, about as much contained in a single cup of coffee, Austrian researchers found a surge in the volunteers’ brain activity, measured by functional magnetic resonance imagery (fMRI), as they performed a memory task. The researchers noted that the memory skills and reaction times of the caffeinated volunteers were also improved when compared to the control group who received a placebo and showed no increase in brain activity.
3. Coffee may help protect against cognitive decline.
In addition to providing a temporary boost in brain activity and memory, regular coffee consumption may help prevent cognitive decline associated with Alzheimer’s disease and other types of dementia. In one promising Finnish study, researchers found that drinking three to five cups of coffee daily at midlife was associated with a 65 percent decreased risk of Alzheimer’s and dementia in later life. Interestingly, the study authors also measured the effect of tea drinking on cognitive decline, but found no association.
4. Coffee is healthy for your heart.
A landmark Dutch study, which analyzed data from more than 37,000 people over a period of 13 years, found that moderate coffee drinkers (who consumed between two to four cups daily) had a 20 percent lower risk of heart disease as compared to heavy or light coffee drinkers, and nondrinkers.
5. Coffee may help curb certain cancers.
Men who drink coffee may be at a lower risk of developing aggressive prostate cancer. In addition, new research from the Harvard School of Public Health suggests that drinking four or more cups of coffee daily decreased the risk of endometrial cancer in women by 25 percent as compared to women who drank less than one cup a day. Researchers have also found ties between regular coffee drinking and lower rates of liver, colon, breast, and rectal cancers.
