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.
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)
Statistically, women who take four or more cups of coffee on a regular daily basis have a 25% reduced chance of falling scourge to this cancer compared to the women who drink less than one cup daily. On the same spectrum, researchers have found a relationship between frequent coffee drinking and lower rates of breast, colon, rectal, and liver cancers.
While they say that the results support moderate coffee drinking as a relatively healthy habit, both Poole and Guallar say the findings don’t go far enough to prompt anyone to change their coffee-drinking habits in the hopes of improving their health. The study did not confirm, for example, that people who do not currently drink coffee should start adding a cup or two a day in order to lower their risk of getting heart disease or any of the other chronic conditions studied. The data also do not support the idea that current coffee drinkers should drink even more coffee to enhance whatever benefits they might be receiving. Too much coffee, the data suggest, starts to bend the benefit curve back down.
Malignant melanomas are the most dangerous and potentially life-threatening form of skin cancer and one of the most common cancer types in the United States. Studies have found that there is potentially as much as a 20 percent lower risk when a person drinks a minimum of four cups of coffee daily. The type of coffee matters here, as the study showed that decaffeinated coffee was not as effective. Studies on non-melanoma cancer and coffee have shown that people were 17 percent less likely to develop the most common form of skin cancer, basal cell carcinoma, if they drank three or more cups of coffee daily.
One UCLA study even famously reversed some symptoms of Alzheimer’s. What was the methodology used? A Paleo diet and lifestyle! Since a typical Paleo diet includes coconut oil, it is wise to add a little bit of this fat to your morning coffee. I personally love the taste of coconut oil in coffee, even though I am typically not a coffee drinker. Yum!
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.

The popularity of the Bulletproof Diet is undeniable. But what started the craze was the world-famous Bulletproof Coffee. By simply adding grass-fed butter to black coffee, you will get a nice brain-boosting buzz — as well as all the health benefits of grass-fed butter. Try blending the coffee with a handheld blender or latte frother if you are stuck with globs of butter on top of your coffee.
What I do instead is use either a very small touch of organic maple syrup or a half packet of natural stevia to just lightly sweeten my coffee. I've also become a big fan of coconut sugar recently, and this is healthier than plain sugar because it does contain some minerals and other nutrients, and has a lower glycemic index than regular sugar. On the other hand, if you like your coffee black with no sweetener at all, that's the healthiest way.
I see people that drink 3-4 cups per day that get a massive headache if they don't have their daily coffee due to caffeine withdrawal. I choose to avoid this addiction by only drinking 1 cup per day max. I drink various teas like green, oolong, black, and white teas at other times, which are much lower in caffeine. Or I like to use rooibos or other herbal teas many times which have no caffeine at all.
By drinking caffeinated or decaffeinated coffee on a regular basis, one can potentially reduce their risk of developing type 2 diabetes. The reduced risk is associated with drinking multiple cups, as many as six a day. It is believed that the antioxidants, such as CGA, found in coffee beans are at least partially responsible for these lower rates. According to some studies, CGA may even help keep insulin levels even.
After the researchers induced myocardial infarction in the mice during their experiments, the extra stores of p27 in the caffeinated cells apparently prevented damaged heart muscle cells from dying. The paper says the mitochondrial p27 also triggered the creation of cells armed with strong fibers to withstand mechanical forces, and promoted repairs to the linings of blood vessels and the inner chambers of the heart. To confirm the protein’s importance, the scientists engineered mice with a p27 deficiency. Those mice were found to have impaired mitochondrial function that did not improve with caffeine.
Independent studies on the coffee consumption patterns of men and women suggest that drinking coffee regularly reduces the risk of developing gout. Researchers in the Nurses’ Health Study analyzed the health habits of nearly 90,000 female nurses over a period of 26 years and found a positive correlation between long-term coffee consumption and a decreased risk for gout. The benefit was associated with both regular and decaf consumption: women who drank more than four cups of regular coffee daily had a 57 percent decreased risk of gout; gout risk decreased 22 percent in women who drank between one and three cups daily; and one cup of decaf per day was associated with a 23 percent reduced risk of gout when compared to the women who didn’t drink coffee at all. Similar findings have been documented for men: another large-scale study, published in the journal Arthritis & Rheumatism, found that men who drank four to five cups of coffee per day decreased their risk of gout by 40 percent, and that those who consumed six cups or more lowered gout risk by 60 percent.
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.
Long term consumption of coffee has also been shown to reduce, although moderately, the risk of stroke (38). Another study pointed out that drinking about five or six cups of coffee a day is associated with the greatest reduction (39) (36%) in stroke risk, and that coffee also contributes to overall reduction of cardiovascular mortality (a less scary way of saying “heart death”).
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.
Alternatively, opt for “milks” and creamers made from almond, coconut, cashew, and other plant sources. They can be much lower in calories than traditional creamers; and they're often produced with all-natural ingredients (read: no high-fructose corn syrup) and provide heart-healthy monounsaturated fat. If you prefer a flavored or sweetened version, check the grams of sugar on the Nutrition Facts panel. Four grams of sugar is equal to one teaspoon.
Studies show that coffee boasts of more antioxidant activity compared to the two antioxidant superstars; cocoa, and tea. In fact, a wide range of detailed lab analysis carried out over the years has identified over 1,000 antioxidants in coffee beans – unprocessed at that. Interestingly, hundreds of more antioxidants come up on roasting the beans. What’s more, a 2012 research labeled coffee as one of the core dietary antioxidants source readily available today.
Though these additions are all fun ways to sneak a little extra something into your morning, let’s face it—our pantries aren’t always stocked with collagen peptides, and we’re guessing your local barista won’t have ashwagandha powder on hand. But one thing Karman Meyer, R.D., recommends is including something most of us already plan on putting in our morning joe.
Although it was once believed that coffee was potentially a carcinogen, more recent studies have found that it may help lower the risk for a variety of cancers, not just skin cancer. The risk of both liver and prostate cancer may be reduced. For example, according to researchers, coffee drinkers were 40 to 50 percent less likely to develop liver cancer than individuals who did not. Other cancers that may be less likely when you drink coffee include oral, uterine, colon, and rectal cancer.
Great article. But the Asians have solved this quandary for us. Drink tea. They have been doing this for longer than time itself and the health benefits are never disputed. Plus, recently there has been too many scientific flip-flops like this. I don’t trust any product that was once on a cancer list and now is on a healthy list! I for one won’t change my habits and will designate coffee as a possible carcinogenic. Please also check to make sure the study was not funded by Starbucks.
Feeling a little slow lately? All it might take to get your body back to working at a normal pace is a little coffee. A 2005 study from the Radiological Society of North America found it doesn’t take much—just a couple cups—to improve your reaction time, making you better at everything from noticing something scary like smoke in your home (and realizing you need to grab the fire extinguisher ASAP) to breaking your car for a stop sign.
