According to Jill Weisenberger, MS, RDN, CDE, one of the easiest ways to make sure your coffee is brewed in a healthy way is to consider how you’re filtering it. Those reusable filters might be tempting (and sure, provide less waste), but using recyclable paper filters has an added bonus for your nutrition. “Filtering coffee with paper removes two compounds, cafestol and kahweol, that raise both total and LDL cholesterol levels,” she explains. Here’s how coffee can help you learn.
If you are already a coffee drinker, it should be reassuring that after decades of research, no strong link can be found between coffee intake and cancer and, to the contrary, a number of health benefits seem to accompany coffee consumption. But, I’m not sure the evidence is powerful enough to recommend an increase in your daily habit. One reason is that we don’t know for sure that coffee consumption actually caused the health benefits observed in these studies. Some other, unmeasured factor could be responsible. Another reason is that the overall effect was small. And, it’s worth noting that some people are quite sensitive to the side effects of coffee.
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.
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.
Haendeler, who drinks six cups of coffee a day, says it can be part of a healthy lifestyle—but is no miracle cure. And she is quick to point out there are no shortcuts to good health. “If you hear about this study and decide to drink coffee but you do nothing else—no exercise, no proper diet—then, of course, this will not work,” she says. “You cannot simply decide, ‘Okay, I’m sitting here and drinking four, five or six cups of coffee and everything is fine.'”

“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.”
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.
But far from that, recent studies have shown that as much as caffeine can stimulate dehydration, moderate consumption of coffee does not dehydrate gym enthusiasts to that extent of interrupting their workout. On the contrary, coffee and it’s battalion of goodness assists in combating physical fatigue thus allowing you a higher endurance margin on the treadmill or under the barbells.
The study builds on earlier work in which the two scientists showed caffeine ramps up the functional capacity of the cells that line blood vessels. The drug does so by getting into cells and stoking the mitochondria, structures within the cells that burn oxygen as they turn glucose into energy.“Mitochondria are the powerhouses of the cells,” Haendeler says. One of the things they run on is a protein known as p27. As Haendeler and Altschmied discovered (and describe in the current paper), caffeine works its magic in the major types of heart cells by increasing the amount of p27 in their mitochondria.
A 2014 study for Flavour found that the color of your coffee mug can influence how sweet or bitter you perceive a cup of coffee to be. Although not definitive, the study found when drinking from a white mug, subjects perceived coffee to be more intense than when drinking from a transparent mug. Of course, more research is needed, so take this study with a grain of salt, but it may be worth swapping out your white mug for a transparent one to make your coffee "taste" less bitter (and thus reduce the amount of sugar you add to it).
Basically, I blend coconut oil and grass-fed organic unsalted butter (yes … butter) into coffee with a dash of vanilla and sometimes a drop of stevia. The blender emulsifies the coconut oil and butter so the texture is more creamy than oily and it is a delicious way to get a boost of beneficial fats. This type of healthy coffee also gives much more extended energy throughout the day without making me jittery.
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.
