So how much coffee is healthy, and how much is too much? Two to three eight-ounce cups per day is considered moderate; heavy coffee drinkers consume four cups or more daily. Remember, the amount of caffeine per coffee beverage varies depending upon the preparation and style of beverage. Eight ounces of brewed coffee may contain as little as 80 to as much as 200 mg of caffeine per cup (an “average” cup probably contains about 100 mg).
You don’t have to be a trained cardiologist to see that that coffee supports heart health. This, it does so by protecting the heart’s muscular chamber against artery damage that may result from inflammation. This way, various heart diseases are warded off including common ailments such as hypertension, thrombosis, heart attack, heart failure, among others
Coffee is one of the world’s most popular beverages for a reason: It not only tastes good and gives you a serious jolt of energy, but it also has plenty of amazing, body-boosting benefits. Which, in all honestly, is a major bonus considering the fact that most people are simply pleased to have something to help them get through their morning meetings.
And those antioxidants? Although researchers have yet to determine the exact mechanisms behind some of the disease-preventing effects, it is important to keep in mind that these compounds may be exerting other beneficial effects, such as acting as an anti-inflammatory. Coffee also contains small amounts of some nutrients, including potassium, niacin and magnesium.
One easy way to keep your heart strong? Drink coffee—just don’t overdo it. A 2012 study published in the journal Circulation: Heart Failure found drinking one or two cups each day could protect against heart failure, decreasing the risk by 11 percent. Drinking more than five cups, on the other hand, could actually do the opposite, potentially causing your body harm.
Research has revealed that regular coffee drinkers can reduce their risk of having a stroke. In women, it seems to lower the risk of heart diseases. It may increase your blood pressure temporarily, but that does not mean a stroke or heart disease is inevitable. It can often work to clear out the system and keep your heart functioning at an optimal level. A study also shows that coffee helps cure arrhythmias, which is abnormal heart rhythms.
One of the more surprising benefits of coffee has to do with the heart. Although coffee temporarily causes an increase in one's blood pressure, drinking two cups daily can help prevent certain cardiovascular problems, such as heart failure. Caffeine may also help prevent disturbances or irregularities in one's heart rhythm. Additionally, there is also a reduced risk of stroke.
If you’re working 80 hours a week, getting three hours of sleep a night, and have no energy because you’re living on carb-heavy takeout, drinking coffee non-stop during the day is a problem. It’s not the coffee; it’s the fact that you’re using the coffee as a crutch. Craving a steaming hot cup or two is fine, being totally dependent on coffee to function isn’t.
For the sake of something real journalists call “integrity” I should point out that coffee has also been shown to have a small, yet positive (which isn’t a good thing in this case) relationship with bladder (25) cancer. However, the same study that reported these finding, also reported that this relationship could also be linked to smoking or other dietary habits.
Parkinson's is a disease of the central nervous system characterized by tremors (and you've probably heard that Michael J. Fox has it). Scientists are still figuring out what combination of environmental and genetic factors causes some people to develop this disease, but some preliminary research suggests caffeine may have a protective benefit against it. In a 2017 literature review published in the Archives of Medical Science, researchers concluded that people who drink moderate amounts of coffee seem to have lower rates of Parkinson's, but they couldn't pinpoint why.
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.
Coffee is not traditionally thought of as anti-carcinogenic, but it has been linked specifically to the prevention of two types of cancer – liver and colorectal cancer, which are the 3rd and 4th deadliest forms of cancer, respectively. It has also shown good results in preventing the occurrence of melanoma in people who consume it regularly. Research says that coffee drinkers have 43% lesser risk of cancer than those who do not drink it.
Increased coffee consumption may reduce risk of type 2 diabetes - the Harvard School of Public Health (HSPH) researchers gathered data from three studies. In these studies, the diets of the participants were evaluated using questionnaires every 4 years, with participants who reported having type 2 diabetes filling out additional questionnaires. In total, 7,269 study participants had type 2 diabetes.

In addition to providing a temporary boost in brain activity and memory, regular coffee consumption may help prevent cognitive decline associated with Alzheimer’s disease and other types of dementia. In one promising Finnish study, researchers found that drinking three to five cups of coffee daily at midlife was associated with a 65 percent decreased risk of Alzheimer’s and dementia in later life. Interestingly, the study authors also measured the effect of tea drinking on cognitive decline, but found no association.

Remember, coffee from popular chains can be loaded with hidden sugars and many other artificial ingredients. Going with black coffee, or making your own, is a much healthier choice. Be sure to use filtered water and organic beans for homemade coffee. If you need a little more spice, try adding grass-fed butter, coconut oil, cinnamon, cocoa or collagen. Remember, healthier coffee doesn’t have to be boring. You can still get your morning caffeine fix – just do it in a more Paleo-friendly way!
Coffee doesn’t only help reduce the risk of developing melanoma—it does the same for basal cell carcinoma too, which affects millions of people every year. A 2012 study of 113,000 participants published by the American Association for Cancer Research found those who drank a minimum of three cups of coffee a day had a 20 percent lower risk of developing the skin cancer than those who didn’t.
Over the past decade, studies have found a link between coffee consumption and a lower risk of dementia. It’s thought that the drink’s high caffeine content might be responsible for the brain-boosting benefits. One small study of subjects who showed signs of memory problems found that, over a 2- to 4-year period, people with lower blood levels of caffeine were more likely to develop dementia than those with higher levels. (Want to brew up a tastier cup of joe? Consider trying some of these six ways to flavor your coffee without added sugar.)
If you’re looking for a unique coffee alternative, try mushrooms in the form of tea. A staple in traditionalChinese medicine, the soft, flat reishi mushroom makes for one invigorating (and healthy) libation. White and Foster recommend combining 1/3 ounce of chopped or powdered reishi mushroom with 3 cups of water, then bringing the tea to a boil and simmering for 30 minutes before drinking in doses.
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.
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.
The only negative health effects the review found were among women, who were at slightly higher risk of developing fractures if they drank more coffee, and pregnant women. Pregnant women who drank more coffee tended to have higher rates of miscarriage, more premature births and more babies born with low birthweight than women who drank less coffee, the study found.
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.
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.
The healthiest way to take your coffee is, of course, black. But if you can’t stand the taste of the bitter grounds on their own, we have a few pieces of good news for you. Firstly, some studies show that probably means you’re not a psychopath — congratulations. But secondly, there are other healthy options out there to add flavor to your beverage — without adding heaps of sugar.
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.
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.
Brushing isn’t the only way to prevent cavities. While coffee is known to stain the teeth, it’s also been found to protect them: A 2009 study published in the Journal of Conservative Dentistry found drinking coffee can help prevent cavities and tooth decay, but there’s a catch—you have to drink it black. Because unfortunately adding in sugar isn’t going to do your smile any good.
We know, we can’t believe it is butter in there, either. Buttered (a.k.a. “Bulletproof”) coffee has been making celebs, athletes, and health bloggers alike get friendlier with fats. Why? Some claim this buttery buzz gives them more energy, improves brain function, and aids in weight loss—particularly if these folks are following a ketogenic diet already.
This recipe is written for a single serving, but you’ll probably love it so much you’ll mix up enough to dish out the single servings at will! The spices blend for a wonderful warm tingling sensation in your stomach, and you’ll find that using coconut milk not only reduces negative effects caused by drinking dairy but also brings out pungent flavors for an amazing blend.
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.
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.
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.
