Many of you may be looking for effective green tips. One tip I can offer you is to recycle used coffee grounds.
Coffee mixed with soil can be used as a natural fertilizer. Used coffee grounds provide gardens with an abundant source of nutrition. Recycling coffee grounds is not only beneficial for gardeners but it helps in reducing the amount of waste going into landfills.
This confusion is due to several factors, and one is the difficulty in separating cause and effect in large, population-based studies. For example, someone who drinks a lot of coffee might also sleep less, smoke more tobacco, drink less water, or work unsociable hours. These factors muddy the statistical waters.
Also, coffee is an incredibly complex beast; it contains more than 1,000 aroma compounds, levels of which vary depending on the type of coffee bean and how it is brewed.
Researchers from Northwestern University in Chicago, IL, took a detailed look at the impact of coffee consumption on our internal chemistry. Their findings were published this week in the Journal of Internal Medicine.
The scientists found that with increased coffee consumption, blood metabolites involved in the endocannabinoid system dropped off. This is the system that gives cannabis its recreational and medical effects.
Coffee may perk up people, but it puts water to sleep.
New research published in the Journal of Physics Communication found that both caffeine (C8H10N4O2) and taurine (C2H7NO3S), a common additive in energy drinks, actually slows the rotation of surrounding water molecules.
Complete with the typical clickbait-style headline, a recent article intoned that the global population is imminently doomed to a world without coffee – and “not much” can be done about this “on a personal level.”
But it could be easy to miss the glimmer of hope buried in the last line:
“This future could look bleak for morning coffee drinkers, but with the help of farmers and scientists, our cup of joe can be protected.”
Rutgers scientists have found a compound in coffee that may team up with caffeine to fight Parkinson’s disease and Lewy body dementia — two progressive and currently incurable diseases associated with brain degeneration.
The discovery, recently published in the Proceedings of the National Academy of Sciences, suggests these two compounds combined may become a therapeutic option to slow brain degeneration.
Coffee may be the greatest nutritional miracle in our world today. What other delicious beverage gives you such a bright, optimistic outlook while making a tremendous impact on your overall health, well-being, and longevity?
Coffee is also one of the greatest indulgences, a sensory experience that rivals the best wines. How else can you make such a robust improvement with such minimal effort. That wasn’t always the case.
I’ve written more than a dozen books on nutrition including two on Coffee. When I was chief medical correspondent for Dateline NBC, Today, NBC Nightly News, and CBS Evening News from the 1980s into the 2000s, and most recently as a contributor on Dr. Oz, we were always on the lookout for the next great nutrition story.
Ironically, we were alert to stories about why coffee was bad for you. At that time, coffee had a reputation for causing harm, and most people feared that it was unhealthy.
