Over the past few years, a lot of research has been done to find the link between coffee consumption and better and healthier aging. These studies are mainly observational, meaning they may establish a correlation but have not proven the underlying mechanisms. But now a new study from Texas A&M University discovered one of the potential paths.
Research recently published in the journal looked at the NR4A1 receptor, “a protein increasingly recognized for its role in aging, stress responses, and disease.” It also responds to compounds in the things we eat and drink, thus enabling our diet to control health and aging, and previous research has shown that NR4A1 activity has positive effects related to inflammation, metabolism and tissue repair.
To understand how coffee interacts with protein, researchers tried to determine which of the readily available compounds triggered NR4A1. They found that not just one compound in coffee, but many “particularly polyhydroxy and polyphenolic compounds such as caffeic acid” bind to the receptor and promote its activity.
Scientists note the importance of this discovery. This means that coffee’s health benefits are not narrow to its caffeine content and actually result from multiple pathways. “Many receptors and many mechanisms are involved,” says one of the study’s authors, Dr. Stephen Sheltered. “We show that this can be one of the vital pathways.”
Although the full extent of coffee’s effects through the NR4A1 protein is not fully understood, the study provides something beyond straightforward observation; offers one of the primary mechanisms leading to all the health benefits of coffee consumption.
