Coffee contains caffeine, which is a known stimulant for humans. Most of us drink coffee to fight drowsiness but there are many other health benefits associated with drinking coffee.
1. Prevents diabetes mellitus
In this research conducted in Singapore, consuming 4 cups or more every day is associated with more than 30% chance of getting diabetes mellitus in future. A review on this issue looked at over 450000 individuals and concluded that drinking 3 or more cups of coffee per day makes an individual 0.6 times less likely to develop diabetes in future.
A group of researchers from Korea looked at how Coffee can benefit pre-diabetic individuals. Pre-diabetics are those with higher than normal blood sugar level but is not high enough to be diagnosed as diabetes mellitus. It is believed that these individuals will eventually progress to diabetes mellitus unless measures such as lifestyle changes are taken.This research concluded that drinking coffee without sugar or creamer for three times a day prevents the onset of diabetes mellitus.
However, if you have a very sweet tooth, healthier alternatives to sugar are available. Find out more about artificial sweeteners from here.

Coffee also seems to prevent other types of cancers. In a review done by researchers in China, it was concluded that coffee consumption is associated with lesser risk of developing mouth, liver, colon, prostate, and womb cancer.
3. Prevents Alzheimer's disease
Coffee consumption has been associated with general benefits on the brain activities. In a recent review, drinking 1 to 2 cups of coffee per day were associated with reduced risk of getting dementia, Alzheimer's disease or any form of cognitive impairment. However the exact mechanism on how coffee reduces the onset of dementia is unclear.
Drinking coffee regularly is proven to be protective against colon cancer, diabetes mellitus, and dementia. However, high consumption of coffee could cause problems such as high blood pressure, anxiety, and insomnia. Thus always consume coffee in moderation and always go for regular health check-ups!
