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.
As discussed earlier, Coffee contains antioxidant phytochemicals called polyphenols. Such chemicals have demonstrated many anticarcinogenic properties in various studies and detailed lab analysis conducted over the past the few decades. So in short, these phytochemicals act as buffers that stave off the chances of tumours bursting up at the very slight exposure to carcinogenic compounds.
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.
“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.”
Unfortunately, there’s no cure for Alzheimer’s, the disorder that slowly causes memory loss and mental decline. But coffee could help reduce the risk of developing it in the first place. A 2016 meta-analysis published in the journal Nutrition found drinking high levels of coffee was associated with a reduced risk of a 27 percent reduced risk of the disease.
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.
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.
While you’ve probably experienced a headache as a caffeine withdrawal (which are the worst, by the way), coffee can also help relieve them. According to the National Headache Foundation, caffeine contains properties that narrow the blood vessels and restrict blood flow, which in turn helps relieve the throbbing pain you’re experiencing in your noggin. In fact, when you add an actual pain reliever into the mix, you can increase the pain relieving effect by 40 percent.
Malignant melanomas are the most dangerous and potentially life-threatening form of skin cancer and one of the most common cancer types in the United States. Studies have found that there is potentially as much as a 20 percent lower risk when a person drinks a minimum of four cups of coffee daily. The type of coffee matters here, as the study showed that decaffeinated coffee was not as effective. Studies on non-melanoma cancer and coffee have shown that people were 17 percent less likely to develop the most common form of skin cancer, basal cell carcinoma, if they drank three or more cups of coffee daily.
