Coffee has also been linked to lower risk of dementia, including Alzheimer’s disease. A 2009 study from Finland and Sweden showed that, out of 1,400 people followed for about 20 years, those who reported drinking 3-5 cups of coffee daily were 65% less likely to develop dementia and Alzheimer’s disease, compared with nondrinkers or occasional coffee drinkers.
From health bloggers to celebs (hey, Jennifer Aniston), it seems like everyone is hopping on the collagen bandwagon this year—adding it to smoothies, cooked meals, and... you guessed it... coffee.

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’ve hurt your liver from years of drinking, coffee could be the superhero you’ve been hoping for. In a 2016 review published in Alimentary Pharmacology and Therapeutics, researchers found drinking two cups of coffee a day had a 44 percent lower risk of ending up with liver cirrhosis. For more on healthy eating, here are a 20 Amazing Healing Foods.
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!
Some curious minds wanted to know exactly who was protected. And why? How? These studies showed that in people with Type 2 diabetes coffee intake was correlated with insulin spikes and increased blood sugar after a meal. Further research has shown that the caffeine in coffee might be the culprit responsible for the secretion of higher levels of insulin from the pancreas.
In fact, according to a 2005 study conducted by researchers at the University of Scranton, coffee is the number one source of antioxidants in the human diet—yes, even over wine and tea. Aside from the caffeine giving you an early-morning energy buzz, those high levels of antioxidants can help protect your body from damage caused by free radicals, as well as fight off disease.

Being coordinated is a true blessing, and if you could use some help in that department, you’re not alone. A 2010 review in the journal Nutrition found the caffeine in coffee can actually enhance neuromuscular coordination, making your brain send messages to your muscles faster. That helps with a lot of things, tripping on random cracks in the sidewalk included.
Want to lower your risk of death? A National Institutes of Health – AARP Diet and Health study of more than 400,000 people revealed that drinking coffee might be the answer. Between 1995 and 2008, male participants drinking even just one daily cup reduced their risk of death by 6%. Drinking either 2-3 cups or 6+ cups reduced the risk by 10% during the timeframe of the study. The greatest reduction of death risk was 12% in the group drinking 4-5 cups.

A 2016 study in the American Journal of Clinical Nutrition found drinking coffee might be able to help you lose weight thanks to caffeine’s ability to increase thermogenesis, fat oxidation, and lipolysis. But more research still needs to be done, so don’t count as your Starbuck runs as a way to drop the pounds. Especially if you’re drinking something that’s not simple, black coffee.
And the WHO is not the only organization to include coffee in its list of foods that are probably harmless and possibly healthy. The 2015 Dietary Guidelines Advisory Committee (commissioned by the secretaries of the US Department of Health and Human Services and the US Department of Agriculture) thoroughly reviewed the evidence and declared that “moderate coffee consumption (three to five cups per day) can be incorporated into a healthy dietary pattern…” And the World Cancer Research Fund International concluded that coffee consumption was linked with a lower risk of several types of cancer.
According to the web site myfoodapedia.gov -- part of the U.S. Department of Agriculture's Center for Nutrition Policy and Promotion -- a 6-ounce cup of black coffee contains just 7 calories. Add some half & half and you'll get 46 calories. If you favor a liquid nondairy creamer, that will set you back 48 calories. A teaspoon of sugar will add about 23 calories.
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.
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.
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.
