Your Daily Grind: New Health Updates On Caffeine And Coffee Consumption

For most of us, our daily coffee routine is not optional but rather essential. It would likely take definitive scientific evidence of negative health consequences to get us to reconsider how much coffee we drink. However, there are occasional rumblings in the literature about whether coffee- especially caffeinated coffee- might have negative consequences, especially when it comes to heart health. A new scientific statement from the American Heart Association (AHA) seems to put that concern to rest and may provide some optimism for indulging in caffeinated coffee while also benefiting your cardiovascular system.

According to this new statement from the AHA, consuming up to 400 mg of caffeine a day (which is the equivalent of 3-5 8-ounce cups of caffeinated coffee) is generally safe for most adults and is linked to a lowered risk for several cardiovascular conditions, including heart failure, heart disease, and stroke in some individuals. The AHA came to this conclusion after extensive review of the existing scientific literature. Experts examined decades of research looking at the effect of caffeine on blood pressure, blood sugar, cholesterol, and heart health more generally. While some of the evidence just demonstrates an association rather than proof, there have been increasing numbers of randomized, controlled clinical trials that demonstrate real cardiovascular benefit from consuming coffee. This safety announcement, however, does not include coffee consumed with such additives as sugar, cream, syrups, or other fillers and does not apply to caffeinated energy drinks or shots, which may contain higher and potentially unsafe amounts of caffeine. More research needs to be done to better understand how the additives you put in your coffee impact its health effects, along with the potential harm caused by highly caffeinated energy drinks.

You can also consume large quantities of tea and continue to stay in the range of 400 mg per day as a safe guideline. So, if you are a tea drinker, you could potentially consume up to 11 cups of green tea or a little over 5 cups of black tea and still be within the same safety and cardiovascular parameters. With all this assurance, it is nonetheless useful to remember that not everyone can consume this amount of caffeine without problems, as different people metabolize caffeine and coffee in different ways, depending on age, genetics, and health, among other factors.  

The good news about coffee, and its potentially positive health benefits, continues to grow, as recent studies reflect more research into connections between coffee consumption and reduced risks of various health conditions. For example, research has consistently found that coffee consumption is associated with better liver health. Whether caffeinated, decaffeinated, or instant, coffee drinking has been linked with lower rates of many liver diseases. Because the benefits have been found even from decaffeinated coffee, it’s likely that the benefits derive not from caffeine but from some of the other chemical compounds found in coffee. And, in fact, a brand new study published in Clinical Gastroenterology and Hepatology, which followed over 350,000 participants for 13 years, found that as little as 1-2 cups of coffee per day could lower your risk of serious liver disease, and up to 5 cups a day was associated with a significant lowering of liver disease risk. In essence, this study, among others, has demonstrated a “liver protective” benefit from coffee consumption.

Other studies have demonstrated such positive health results as a lower risk of Type 2 diabetes, along with a lower risk for Parkinson’s, with daily coffee consumption. So, as the positive scientific data continues to mount, brew yourself a fresh cup and read here to find out more about the growing evidence supporting the health benefits of coffee.
