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.”
You probably think of coffee as a pick-me-up. But its effects don’t kick in for about 30 minutes. That means if you enjoy a cup of coffee just before taking a 20-30 minute nap, you may wake up feeling extra-energized. Just be sure you don't try this hack too late in the afternoon; it's best to stop consuming caffeine six hours before you hit the hay.

Cardamom has been dubbed the “queen of spices”—and it’s not just because of its rich, warm taste. In some ancient medicinal traditions, this powerful spice was used to treat everything from gum infections to tuberculosis. And while we’re not recommending you try to whip up a DIY cardamom cure for either of those, one recent study suggests the spice may have antimicrobial properties so you can fight off pesky bacteria like E. coli. And adding it to your coffee might just improve your social health, since it’s been used as a natural breath freshener and, well, coffee breath is a thing.
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.
There’s no need to try anything crazy; the only performance enhancer you really need is coffee. Research has shown its ability to give workouts a boost and increase athletic performance, and that’s exactly why you’ll find so many Olympians drinking it: One report from the journal Applied Physiology, Nutrition, and Metabolism found the majority of the 20,686 Olympic athletes analyzed had caffeine in their urine.
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.
You can improve your coffee by adding real cream. This means organic and grass-fed. Cream like this can be purchased at all major health food stores, and will give you the health benefits of CLA (conjugated linoleic acid). There is also usually a nice amount of vitamin K2 present in full-fat cream. This is important because adequate intake of vitamin K2 has been linked with lower rates of cancer and heart disease. Full-fat cream has even been linked to more successful weight loss.
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)
You might think that nonfat, sugar-free vanilla syrup is a healthy choice, but low-calorie doesn’t always translate to health benefits. Swinney suggests weaning yourself off sweeteners completely if you can, but if you can’t, be super picky about the additives you’re putting into your brew. “Pick organic cream to whiten your coffee or make your own packaging-free alternative milk from oats or nuts. Creamers often have artificial flavors, sweeteners, and other additives, so you’re better off using organic milk or cream plus organic brown sugar,” she says. Next, don’t miss these 13 surprising uses for coffee.
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”).
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.
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.
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.
A recent study appearing in the Journal of the National Cancer Institute looked at the coffee-drinking habits of more than 447,000 people over 10 years. The researchers found that those who drank four or more cups of caffeinated coffee each day had a 20 percent lower risk of developing melanoma than people who drank decaffeinated coffee or no coffee.
If Starbucks is your favorite coffee house, then you’ve likely seen the cinnamon on the milk counter when you go to top off your brew. Next time, take advantage and give your health a boost. Swinney says that cinnamon can make your beverage even better for you, thanks to its antioxidant properties, not to mention a slew of other benefits. “Cinnamon has been shown to lower blood sugar in many clinical studies. Adding spices add antioxidants and sweetness without calories, helping to cut back on the sugar you might add to coffee. Cloves have anti-inflammatory and antibacterial properties,” she explains. Check out 10 weird facts about coffee you never knew.
“Absolutely not,” says Donald Hensrud, medical director of Mayo Clinic's Healthy Living Program. “You have to enjoy life, and if you enjoy tea, keep on enjoying it. It’s all good. There are health benefits to coffee, to black tea and to green tea.” But there can also be problems associated with higher doses of caffeine, he notes. The amount in more than two cups of coffee a day, for example, can interfere with conception and increase the risk of miscarriage. And, he says, because individuals metabolize caffeine at different rates, slow metabolizers may be more susceptible to side effects such as heartburn, insomnia, heart palpitations and irritability.
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.
