The Health Benefits of Java.

coffee drink  As avid coffee drinkers, the staff at Foodexposed is partial to coffee. Recent studies have confirmed the health benefits of our favorite Java and that consumers who drink coffee are less likely to have type 2 diabetes, Parkinson’s disease, and dementia, certain types of cancers, heart rhythm problems, and strokes.

A 2005 study reviewed nine studies on coffee and type 2 diabetes. Of more than 193,000 people, 35% were less likely to have type 2 diabetes if they drank six or seven cups daily compared to people who drank fewer than 2 daily cups. The findings were the same regardless of sex, weight, or geographic location.

In a more in-depth study Australian researchers reviewed 18 studies of approximately 458,000 people. They found a 7% drop in the odds of having type 2 diabetes for every extra cup of coffee that was consumed.

The health benefits of coffee are not specifically linked to caffeine, rather they are due to coffee’s strong antioxidant properties.

A study of about 130,000 Kaiser Permanente health plan members revealed that people who reported drinking 1-3 cups of coffee per day were 20% less likely to be hospitalized for abnormal heart rhythms (arrhythmias) than nondrinkers, regardless of other risk factors.

In 2009, a study of 83,700 nurses enrolled in the long-term Nurses’ Health Study showed a 20% lower risk of stroke in those who reported drinking two or more cups of coffee daily compared to women who drank less coffee or none at all. That pattern held regardless of whether the women had high blood pressure, high cholesterol levels, and type 2 diabetes.

Coffee has also been linked to lower risk of dementia, and Parkinson’s disease including Alzheimer’s disease. A 2009 study from Finland and Sweden showed that, out of 1,400 people followed for about 20 years, those who reported drinking 3-5 cups of coffee daily were 65% less likely to develop dementia and Alzheimer’s disease, compared with nondrinkers or occasional coffee drinkers.
