According to leading neurologists and toxicologists, caffeine is believed to affect areas of the brain responsible for concentration and memory. And so as a direct consequence, caffeine provides a boost to the short-term memory as well as an individual’s concentration acuity. However, it is worth noting that it is not exactly clear how long the boosting lasts. Better yet, it is not clear how it may vary from one person to another.

Need a little boost to get you through your HIIT workout? A 2013 study from PLoS One shows that athletes who consumed coffee an hour before exercise had greater performance than those who drank decaffeinated coffee. Plus, a 2015 study from the International Journal of Sport Nutrition and Exercise Metabolism suggests that people who drink coffee before a workout burn more calories after exercise, also known as EPOC (excess post-exercise oxygen consumption). This means that even if your spin class is over, your body will continue to burn more calories. We’ll drink to that! ☕
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.
Coffee is one of the most chemically treated foods in the world (global demand is high, so methods of growing it often are chemical fertilizer-pesticide-herbicide intensive). This is bad for you (since pesticide residues can end up in your cup) and really bad for the planet. High demand and the fact that it’s generally grown in poorer countries also means labor practices are a major issue. Buy organic and fair-trade if and when you can.
In addition to being pretty terrible for the environment, Immer says Keurig Coffee Makers also pose some potential health dangers. Not only do you expose yourself to plastic that’s been heated, but Keurigs tend to get dirty, fast. “The water tanks in a Keurig can never truly be flushed and cleaned. We are concerned about mold and bacteria growth in these tanks over time, much like commercial ice machines,” Immer says.
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.
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.
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.

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.
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.
