![]() Your morning coffee could help lower your risk of death. The researchers found that those who drank four or more cups of caffeinated coffee each day had a 20% lower risk of developing melanoma than people who drank decaffeinated coffee or no coffee. Reduce melanoma risk.Ī 2015 study appearing in the Journal of the National Cancer Institute looked at the coffee-drinking habits of more than 447,000 people over 10 years. While the reason isn't clear, one possibility is that coffee helps to improve blood vessels' control over blood flow and blood pressure. Data from 36 different studies showed that people who drink three to five cups of coffee per day had a lower risk of heart disease than those who drink no coffee or more than five cups per day. In 2013, the journal Epidemiology and Prevention published a review of studies analyzing the correlation between coffee consumption and cardiovascular disease. The study looked at the original data from three well-known heart disease studies: the Framingham Heart Study, the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study.Īlthough there's not enough evidence to support prescribing coffee to lower your risk of heart disease risk, this recent revelation seems to strengthen previous findings that coffee is, in fact, good for heart health. Promote heart health.Īccording to a study published in 2021 in the American Heart Association journal Circulation: Heart Failure, drinking one or more daily cups of plain, caffeinated coffee was associated with a significant reduction in a person's long-term risk of heart failure. Several studies published in respected journals have found that coffee drinking has beneficial effects on the liver, including reducing the risk of death from liver cirrhosis, decreasing harmful liver enzyme levels and limiting liver scarring in people who have hepatitis C. When the researchers re-evaluated the subjects two to four years later, those whose blood levels contained caffeine amounts equivalent to about three cups of coffee were far less likely to have progressed to full-blown dementia than those who had consumed little or no caffeine. In a 2012 study published in the Journal of Alzheimer's Disease, Florida researchers tested the blood levels of caffeine in older adults with mild cognitive impairments, which can be a precursor to severe dementia, including Alzheimer's disease. (You'd have to drink nearly eight cups of brewed black tea to get the same amount of caffeine.) 4. Control Parkinson's disease symptoms.Ī number of studies have suggested that consuming caffeine can reduce your risk of developing Parkinson's disease - and research published in 2012 in the journal of the American Academy of Neurology showed that a daily dose of caffeine equivalent to that found in two eight-ounce cups of black coffee can help to control the involuntary movements of people who already have the disease. ![]() Caffeine has been shown to raise both blood sugar and insulin levels in people with the disease. If you already have Type 2 diabetes, however, you should avoid caffeinated products, including coffee. ![]() The reason may be the antioxidants in coffee, which reduce inflammation (inflammation contributes to your Type 2 diabetes risk). Those who increased their coffee intake by more than a cup a day over a four-year period had an 11% lower risk of developing Type 2 diabetes those who decreased their intake by one cup per day had a 17% higher risk of developing the disease. ![]() Protect against Type 2 diabetes.Ī 2014 study by Harvard researchers published in the journal Diabetologica tracked nearly 124,000 people for 16 to 20 years. ![]() The analysis found that during the study period, coffee drinkers were 17% less likely to die early from any cause, 19% less likely to die of heart disease and 18% less likely to develop cancer than those who don't drink coffee. Improve overall health.Īn analysis of nearly 220 studies on coffee, published in the BMJ in 2017, found that coffee drinkers may enjoy more overall health benefits than people who don't drink coffee. Though researchers don't always know exactly which of coffee's ingredients are responsible for producing their studies' health-boosting results, there's evidence that drinking coffee may help do the following: 1. The most commonly studied are caffeine (a nervous-system stimulant that's known to have positive cognitive effects) and polyphenols (antioxidants that can help slow or prevent cell damage). A lot of recent research suggests that coffee offers a host of potential health benefits.Įvery day, Americans drink 400 million cups of this incredibly complex beverage, which contains more than 1,000 compounds that can affect the body. Turns out that coffee's good for more than jump-starting our mornings or keeping us awake during meetings. ![]()
