Every 5 years, the U.S. Department of Agriculture (USDA) and Department
of Health and Human Services (HHS) issues a new edition of the Dietary
Guidelines. These are dietary
recommendations for Americans to practice healthy eating habits.
Shaped by the Dietary Guidelines Advisory Committee (DGAC), these guidelines have an enormous impact on US perceptions and behaviors regarding nutrition and health, which is why it’s critical to communicate the science on coffee and health.
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.
From painting to planting to power-washing, volunteers pitched in to help with much-needed school beautification and maintenance projects. (One overwhelmed teacher shared that she and her husband had been working on weekends and spending their own money to make classroom repairs.)
In one afternoon, the NCA team made the kind of progress only possible when a committed (and well-caffeinated) community comes together for a common cause.
Here are a few highlights from the NCA 2019 Coffee Gives Back Day of Service:
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.
