According to the report, coffee consumption is associated with a lower risk of melanoma and leukemia, as well as prostate and endometrial cancers. What’s more, a 2017 University of Southern California study found that coffee drinkers were 26 percent less likely to develop colorectal cancer than non-coffee drinkers. And those who drank more than 2.5 servings a day were 54 percent less likely to get the cancer.
If you’re looking to add an extra health kick to your coffee but still want it to look like, well, coffee, try sprinkling in some ashwagandha powder. You may want to combine this with some cinnamon and coconut oil since it can have a pretty strong flavor, but some people are swearing by this adaptogen trend. While it’s used heavily in Ayurvedic medicine, mainstream health connoisseurs are starting to use it more and are noticing that it may help reduce stress and possibly even increase physical stamina.
So how much java is too much? It's wise to stick to no more than 3 to 4 cups per day. Certain groups, such as people with hypertension and the elderly, may be more susceptible to the adverse effects of caffeine. Pregnant and breast-feeding women will want to limit intake to a maximum of 200 to 300 milligrams a day of caffeine (the amount in 2 to 3 cups of coffee). The American Congress of Obstetricians and Gynecologists recommends that pregnant women cap caffeine consumption at 200 milligrams a day.
It’s enough to make a tea drinker buy an espresso machine. In a new study scientists in Germany report they were able to modify a common age-related defect in the hearts of mice with doses of caffeine equivalent to four to five cups of coffee a day for a human. The paper—the latest addition to a growing body of research that supports the health benefits of drinking coffee—describes how the molecular action of caffeine appears to enhance the function of heart cells and protect them from damage.
Lastly, it's extremely important to choose  organic coffee beans , as conventional coffee is one of the most heavily treated crops with pesticides, fungicides, and herbicides.  Remember that one of the many health risks with these chemicals is that some pesticides can act as "xenoestrogens" in your body, disrupting hormone balance for both men and women.  Chronic xenoestrogen exposure can also be one cause of "stubborn abdominal fat" in both sexes as well as "man boobs" in men... so choose organic as often as you can with most foods, but especially with coffee!
Don’t feel bad about those days you drink a little too much coffee: A 2016 study published in the Journal of Neurology, Neurosurgery, and Psychiatry found drinking a high consumption—we’re talking more than four a day—can help reduce your risk of multiple sclerosis, a disease that causes the immune system to attack the protective covering of the nerves in the brain, spine, and eyes. And not just a little—by 31 percent.
Other studies have tried to tease apart which ingredients in coffee contribute to its health benefits. Those might include its antioxidants, which can combat cancer, and anti-inflammatory compounds, which can reduce the risk of chronic diseases such as heart conditions and even neurodegenerative disorders like Alzheimer’s, as well as the risk of liver diseases like cirrhosis and cancer.
Do you drink your coffee first thing in the morning? You may want to think again.”Caffeine causes sugar to release into the bloodstream, creating a spike in insulin and a resulting drop in blood sugar,” says health coach and nutritionist Kristie Santana. “This will cause your body to require even more sugar, which will lead to food cravings.” Additionally, studies have found that drinking coffee first thing in the morning interferes with our bodies’ production of cortisol, which can increase your tolerance to caffeine and make you more reliant on the drink.
In a 2007 study published in the International Journal of Dermatology, researchers found caffeine could be a potential hair growth stimulant for men with androgenetic alopecia, a common type of hair loss. In fact, the growth of the hair follicles that were treated with caffeine increased 46 percent and the life cycle of the hair was extended by 37 percent. And once you’re hair is luscious and flowing, here’s the Haircut That Will Shave 10 Years Off Your Age. 
Need a little boost to get you through your HIIT workout? A 2013 study from PLoS One shows that athletes who consumed coffee an hour before exercise had greater performance than those who drank decaffeinated coffee. Plus, a 2015 study from the International Journal of Sport Nutrition and Exercise Metabolism suggests that people who drink coffee before a workout burn more calories after exercise, also known as EPOC (excess post-exercise oxygen consumption). This means that even if your spin class is over, your body will continue to burn more calories. We’ll drink to that! ☕
