While working in a large corporate office I read something that spouted all the ill effects of caffeine and the benefits of green tea, I drank about 6 cups per day. Hay, it was free, and always a terrible glass Bunn pot sitting on the burner. (Burner is a great name for it). So, I started drinking green tea, it was weak and not very flavorful, so that did not last long. I saw another article showing the benefits of coffee and article after article after that and went back to coffee. Here is another recent blog post quoting Stanford researchers about the benefits of my good old cup of coffee.
In an article on Big Think .com that quotes Stanford Researchers, caffeine intake is associated with longer life, decreased Diabetes and certain forms of cancer and other bad things.
Americans are coffee addicts, and perhaps more so nowadays, now that we're working longer hours and getting less sleep than decades past. 50% of Americans drink at least one cup per day. In the past, the pendulum on coffee, and in particular caffeine, swung back and forth as to whether moderate consumption was healthy or not. At one time, too much was thought bad for the heart.
Today, moderate caffeine consumption is actually considered healthy. Tea and coffee both contain antioxidants which rid the body of free radicals—proven to harm cells. One recent study found that coffee consumption in women can decrease the risk of dementia. Another found that drinking coffee can lessen the impact of liver disease.
In a recent study published online in the journal Nature Medicine, researchers at Stanford University discovered that among certain adults, caffeine can block an inflammation pathway which leads to heart disease. 100 human participants underwent extensive assessment, including giving researchers their family and medical histories, answering survey questions, and giving blood. This pathway is associated with low-grade, chronic inflammation, known to contribute to disease and aging.
Next, the study zeroed in on two subgroups of older subjects. One had both gene clusters activated, while the other had one or both activated but at a low level. Among those with high cluster activity, nine out of the 12 had high blood pressure. But only one of 11 participants who had low cluster activity did. Colleague and co-author Francois Haddad, MD ran a follow-up study, finding that the group with high gene cluster activity had more advanced cases of atherosclerosis or hardening of the arteries.
Those who had high activity were more likely to have free radicals in their system. Also, those who had low activity reported at least one close relative who lived to age 90 or older. Meanwhile, those who saw high activity at age 85 or above in 2008, were more likely to have passed away by 2016. In addition, IL-1-beta and other byproducts produced by free radicals were found at high levels in the systems of the high cluster group.
Researchers incubated immune cells with some of those nucleic-acid metabolites. This was found to increase the activity of one of the two gene clusters. The result was IL-1-beta. They injected this into healthy mice who soon developed system-wide inflammation and high blood pressure. Then, researchers took blood from older participants who had gene cluster activity along with a high rate of caffeine consumption. They found that those inflammation-causing substances were inhibited over time, due to caffeine's presence.
Though a marvelous result, there remain some loose ends. One is that researchers couldn't prove a cause-and-effect relationship between caffeine consumption and longevity, merely a strong correlation. The second and perhaps more important was, they weren't sure why some people have this gene cluster activation while others don't. Some mechanisms have already been implicated, and those will be the focus of future studies.
Conclusion... Drink coffee and enjoy a long life? Yea.. lets go with that!
Java Dragon is a small start up company hatched after I was laid off from my tech job in early 2017. I love coffee and so my wife and I decided to get into the coffee business to bring barista quality coffee to offices in Chicago.
