“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.
Men who drink coffee may be at a lower risk of developing aggressive prostate cancer. In addition, new research from the Harvard School of Public Health suggests that drinking four or more cups of coffee daily decreased the risk of endometrial cancer in women by 25 percent as compared to women who drank less than one cup a day. Researchers have also found ties between regular coffee drinking and lower rates of liver, colon, breast, and rectal cancers.
Don’t feel bad about those days you drink a little too much coffee: A 2016 study published in the Journal of Neurology, Neurosurgery, and Psychiatry found drinking a high consumption—we’re talking more than four a day—can help reduce your risk of multiple sclerosis, a disease that causes the immune system to attack the protective covering of the nerves in the brain, spine, and eyes. And not just a little—by 31 percent.
Other than that, antioxidants play a significant role in neutralising free radicals that naturally occur as a part of daily metabolic functions. However, the radicals in question are those that can cause oxidative stress and not the useful type. In other words, the antioxidants in a steaming cup of coffee can go a long way in keeping you healthy at a micro-level. And they do so by protecting your cells from any possible external physical damage.
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.
We’ve been conditioned to believe that caffeine is dehydrating, one of the primary reasons why fitness experts recommend nixing coffee pre- and post-workout. However, recent research suggests that moderate caffeine consumption — up to about 500 mg, or about five cups per day — doesn’t dehydrate exercisers enough to interfere with their workout. In addition, coffee helps battle fatigue, enabling you to exercise longer.
How it works: There are several theories about how coffee may help prevent or protect against cognitive decline. One working theory: caffeine prevents the buildup of beta-amyloid plaque that may contribute to the onset and progression of Alzheimer’s. Researchers also theorize that because coffee drinking may be associated with a decreased risk of type 2 diabetes, a risk factor for dementia, it also lowers the risk for developing dementia.
Want to add even more antioxidants to your coffee and control your blood sugar? I thought so. How exactly does one do that? It’s simple: just add a pinch of cinnamon to your cup! Interestingly, cinnamon has a fairly long history of use as both a spice and a medicine. While it can be used at any time of year, it no doubt tastes best during the cold, winter months.
It’s in your best interest to learn and put these mindfulness exercises into practice. Now that our habitat has become too technological and many people just don’t want to unplug, engaging in daily prayer, celebrate your friends’ victories, and listening to your spouse are among the best ways to be mindful about what you are doing and how you are living.
