1. Caffeine Lowers Risk of Some Types of Cancers
One of the major caffeine (coffee) health benefits is lowering the risk of many types of cancers. For instance Liver Cancer, Colorectal Cancer, Skin Cancer, Oral Cancer, Prostate Cancer (in men) and Endometrial Cancer (in women).
Cancer is characterized by the uncontrolled cells growth in your body and is one of the world’s leading causes of death. Coffee keeps a check on such free radical cells and thus the coffee prevents risk of cancer.
1.1 Caffeine (Coffee) Lowers Skin Cancer Risks
Cancer Research has published an observational study (a study that shows an association but not causation) on coffee health benefits in July 2012. According to this research, people in a test group drank four cups of coffee a day. As a result, professionals reported that higher the consumption of caffeine was, the lower was the risk of developing basal cell carcinoma, the most common type of skin cancer
1.2 Coffee Lowers Liver Cancer Risks
Some studies (study 1, study 2) show that coffee drinkers have up to a 40% lower risk of liver cancer. To make a note, Liver cancer is the Third Leading Cause of Deaths in world.
1.3 Coffee Lowers Colorectal cancer Risks
The American Journal of Clinical Nutrition has published a study in June 2012. As per the study, out of 489,706 individuals those who drank 4-5 cups of coffee per day had a 15% lower risk of colorectal cancer. To clarify, Colorectal cancer is the fourth leading cause of death in world.
1.4 Coffee Health Benefit to Lower Prostate Cancer Risks (In Men)
NCBI has published a study in June 2011 which shows that regular coffee intake may decrease the risk of developing prostate cancer (in men) by 20%.
1.5 Coffee Health Benefit to Lower Endometrial Cancer (in women) Risk
According to the same study of NCBI, coffee may decrease the risk of developing endometrial cancer (in women) by 25 %.
1.6 Prevents Oral Cancer
American Journal of Epidemiology has published an observational study in January 2013. According to this study, out of 968,432 men and women, 868 were died with oral cancer during the 26-year study period. Therefore It was observed that the regular coffee drinkers who were taking around four cups of caffeinated coffee daily, had about half the death risk from oral cancer.
2. Coffee Health Benefit to Improve Mental Performance and Mental Alertness
European Food Safety Authority (EFSA), Parma, Italy has published a study in 2011. According to this study the moderate intake of caffeine can help you stay focused. Because the coffee increases the brain functions and concentration with enhanced firing of neurons.

Caffeine (The stimulant found in coffee) is the most commonly consumed psychoactive substance in the world. Caffeine is absorbed into the blood and travels through your brain along with blood stream. In brain, caffeine acts to block an inhibitory neurotransmitter i.e. Adenosine.
This blockage action of Adenosine acts to increase the amount of other neurotransmitters such as norepinephrine and dopamine. Hence this increase in norepinephrine and dopamine neurotransmitters leads to enhanced firing of neurons (study says). This causes a stimulant effect which improves the mental performance, various brain functions, energy levels, your mood and mental alertness.

Caffeine breaks down the body fat cells into fatty acid released into blood. So our body cells can use these cells as fuel to produce energy (study 1, study 2). This eventually increasing the physical operformance of our body.
Another study at NCBI says that Have caffeine found in coffee increases level of adrenaline in your blood. To clarify, Adrenaline is a stimulant hormone which prepares your body for physical exertion.
Having a couple of coffees at your favorite coffee shop before you head to the gym could power up your workout, says Michael Duncan, PhD.

And the study shows that people who drank around four cups of instant coffee or two cups of filtered coffee before their exercise, performed more better than those who didn’t.

To clarify, Coffee prevents the neural inflammation which may be the cause of developing Multiple Sclerosis
14. Caffeine Lowers The Risk of Parkinson’s Disease
Caffeine in particular has great effect to lower the risk of Parkinson’s disease as per the study published in American Journal of Epidemilogy
Parkinson’s disease is caused by death of dopamine generating neurons in the brain. This disease comes at number two among the most common neurodegenerative diseases in the world; while the Alzheimer’s disease is at number one.
Same as with Alzheimer’s, the Parkinson’s Disease also doesn’t have a cure so it becomes more important to focus on prevention from the disease. Studies show that people who drink coffee regularly have 32%-60% lower risk of developing Parkinson’s disease
