The difference could come down to just a few cups of coffee a day, study co-author and Stanford University professor of microbiology and immunology Mark Davis told Live Science. The study’s findings may explain why coffee drinkers tend to live longer than those who do not drink coffee, the researchers suggested in a statement from Stanford University.

The results showed that the older participants had higher levels of an inflammatory protein, called IL-1-beta, had a greater risk of stiff arteries, high blood pressure and mortality during the study period, compared with those who had lower levels of this inflammatory protein.

Next, researchers investigated why some older adults showed lower activation of the genes that encode IL-1-beta, and found an interesting correlation i.e., the older participants who reported that they consumed more caffeinated beverages generally showed a lower activation of these inflammation-causing genes.

For now, drinking coffee may be one way to decrease the inflammatory processes that naturally come with age, the researchers wrote in their paper.

But the researchers said they hope their work will spur other scientists to develop more sophisticated drugs that could target these culprits of inflammation.
