There are various theories on how coffee can help prevent or better yet, protect cognitive decline. But before that here is a quick fact, caffeine in coffee prevents beta-amyloid plaque build-up. The plaque can contribute to the beginning as well as the progression of Alzheimer’s. Besides, researchers theorise that since a regular cup of coffee can keep dietary diabetes away (a dementia risk factor), it can also be said to minimise the danger of developing dementia.
If you consider the “health” of your coffee as more than just what you’re putting in your body, but also how your coffee beans are grown, picked, and get to you, Swinney suggests you’re taking your coffee habit to a more beneficial level—not only for yourself, but for the world. “Drink clean and with a conscience. Choose fair trade or coffee with other certifications that help third-world farmers improve their living conditions. Give some thought to the packaging involved in single-serve coffee—it requires much more packaging and contains a larger carbon footprint for getting to the store.”
According to the report, coffee consumption is associated with a lower risk of melanoma and leukemia, as well as prostate and endometrial cancers. What’s more, a 2017 University of Southern California study found that coffee drinkers were 26 percent less likely to develop colorectal cancer than non-coffee drinkers. And those who drank more than 2.5 servings a day were 54 percent less likely to get the cancer.
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.
In fact, coffee shows more antioxidant activity than green tea and cocoa, two antioxidant superstars. Scientists have identified approximately 1,000 antioxidants in unprocessed coffee beans, and hundreds more develop during the roasting process. Numerous studies have cited coffee as a major — and in some cases, the primary — dietary source of antioxidants for its subjects.
Your daily cup of coffee may be doing more for you than providing that early-morning pick-me-up. The health impact of coffee has long been a controversial topic, with advocates touting its antioxidant activity and brain-boosting ability, and detractors detailing downsides such as insomnia, indigestion and an increased heart rate and blood pressure. But the latest wave of scientific evidence brings a wealth of good news for coffee lovers. Here are 10 reasons drinking coffee may be healthier for you than you thought.
By drinking caffeinated or decaffeinated coffee on a regular basis, one can potentially reduce their risk of developing type 2 diabetes. The reduced risk is associated with drinking multiple cups, as many as six a day. It is believed that the antioxidants, such as CGA, found in coffee beans are at least partially responsible for these lower rates. According to some studies, CGA may even help keep insulin levels even.
“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.
