Bladder and pancreatic cancer. Studies performed more than 30 years ago suggested a potential link between coffee consumption and cancers of the bladder, pancreas, and possibly others. Since then, better research has largely refuted these concerns. In fact, some of the older studies raising red flags about a cancer link have since been used as examples of “fishing expeditions” and weak research methodology.
Other studies have tried to pinpoint exactly what in caffeine is helping to halt the onset of these diseases. A 2014 study (14) found that caffeine blocks various tau receptors (a protein that contributes to brain cell degeneration). Another study found that caffeinated coffee increased GCSF (15) - a substance greatly decreased in Alzheimer’s patients - levels in the bloodstream.

You might think that since we boil water to brew coffee, you don’t have to worry whether it’s filtered. But Swinney says filtered water is a smart choice, if not for taste, but for health. “Filtered water ensures there are not any unwanted heavy metals like lead or copper, that might be found in old pipes. Tap water also contain many chlorine disinfection byproducts which can be harmful long term,” she says. “You should also avoid using well water unless it’s been tested for contaminants.”

“For example, prior studies have suggested that variants in CYP1A2, (a gene) encoding the enzyme responsible for more than 95 percent of caffeine metabolism, may alter associations of coffee drinking with cardiovascular-related outcomes, with slower caffeine metabolizers having higher risk of developing hypertension (high blood pressure) or having a myocardial infarction (heart attack) relative to their non-drinking counterparts, whereas faster caffeine metabolizers who drink coffee are at no or lower risk of these outcomes.”


Studies have shown that there is an ingredient in coffee that protects against a liver disease called cirrhosis. If you have never heard of cirrhosis before, it a condition where your liver tissue is damaged and replaced with scar tissue. It can develop several ways like from infections, obesity, and other conditions, but especially from drinking too much alcohol. Drinking coffee on a regular basis has been shown to be a natural detox to help protect against the onset of cirrhosis, especially alcoholic cirrhosis. (8)
Poole notes that the analysis included a number of different studies, each with different designs, and not all of them may have adjusted for potential confounding effects that could skew the connection between coffee and health outcomes. Coffee drinkers, for example, also tend to smoke more than non-drinkers, and smoking has an effect on early death, heart disease and certain cancers.
Joseph Bennington-Castro is a Hawaii-based contributing writer for Live Science and Space.com. He holds a master's degree in science journalism from New York University, and a bachelor's degree in physics from the University of Hawaii. His work covers all areas of science, from the quirky mating behaviors of different animals, to the drug and alcohol habits of ancient cultures, to new advances in solar cell technology. On a more personal note, Joseph has had a near-obsession with video games for as long as he can remember, and is probably playing a game at this very moment.

If you consider the “health” of your coffee as more than just what you’re putting in your body, but also how your coffee beans are grown, picked, and get to you, Swinney suggests you’re taking your coffee habit to a more beneficial level—not only for yourself, but for the world. “Drink clean and with a conscience. Choose fair trade or coffee with other certifications that help third-world farmers improve their living conditions. Give some thought to the packaging involved in single-serve coffee—it requires much more packaging and contains a larger carbon footprint for getting to the store.”


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.

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! ☕


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!
A latte or cappucino can be okay as long as you make sure to ask for it unsweetened, and then use your own stevia if you need a light sweet taste.  Since almost every coffee shop only has either sugar or artificial sweeteners as options, I always carry packets of stevia on me when I know I might be getting coffee at a coffee shop on a particular day.

If your focus is weight loss, green coffee extract could be an effective aid. Following a 22-week study of 16 overweight adults, researchers discovered participants given green coffee bean extract had undergone significant weight loss with 37.5% of them transitioning from being at a pre-obesity weight to a normal weight range. If you’re battling the bulge, consider complementing your workouts by looking at the green bean capsule aisle of your local health nutrition store. 

An alarming 11.8% of American men over the age of 20 have diabetes. Needless to say, it’s a growing concern and one receiving a great deal of attention in the medical community. Between 1986 and 1998, Harvard researchers tracked the coffee consumption and occurrence of type-2 diabetes of more than 40,000 men. They discovered that long-term coffee drinkers had a significantly reduced risk of developing type-2 diabetes and statistics indicated the risk decreased the more they drank. Just remember to limit your sugar!
If you’re constantly resisting down the urge to hit your bloodstream with caffeine, relax. It’s really okay to get a steady stream of java—so long as you’re stopping at a reasonable time before bed (typically 2 p.m., since coffee has a half-life of 8-10 hours), not swallowing a pot a day, and avoiding syrups and artificial sweeteners (check out these 15 ultra-healthy add-ins instead). And we’re not just saying so because the energy jolt is just that good. Coffee also has a slew of health benefits.
One of the best tricks for slashing your sugar intake is to reach for “sweet” spices, like cinnamon, ginger, nutmeg, and cloves. In addition to boosting flavor and aroma, spices seriously up your antioxidant intake. (Cinnamon has the added perk of helping with blood sugar and insulin regulation.) You could also try a spice combo, like pumpkin or apple pie spice, or sprinkle in raw (non-Dutched) cocoa powder, another antioxidant-rich add-in.
It’s in your best interest to learn and put these mindfulness exercises into practice. Now that our habitat has become too technological and many people just don’t want to unplug, engaging in daily prayer, celebrate your friends’ victories, and listening to your spouse are among the best ways to be mindful about what you are doing and how you are living.
