Khaberni - A new study has disclosed some health benefits associated with coffee, indicating that its effects may partially be due to the interaction of its compounds with a protein that plays a role in the response to stress and aging.
Extensive research over decades suggests that coffee consumption is associated with an increase in life expectancy and a decreased risk of several chronic diseases. Population studies have shown that coffee drinkers are less likely to suffer from age-related diseases such as metabolic diseases, certain types of cancer, Parkinson's disease, dementia, and heart disease.
It is believed that this association is partly due to coffee containing active compounds such as polyphenols and flavonoids, which have antioxidant and anti-inflammatory properties, helping to protect cells from damage and aging. However, the precise mechanism through which these compounds operate has remained largely unclear until now.
The recent study clarifies that coffee may affect the body through a protein known as NR4A1, a cellular receptor that regulates the body's response to stress and damage, and is important in aging processes and overall health.
The researchers say that this protein is involved in regulating gene activity when the body is under stress, and it plays a role in vital processes such as inflammation, metabolism, and tissue repair, which are directly associated with aging diseases.
In this context, Steven Seif, one of the authors of the study published in the journal Nutrients, explained: "Some of the health effects of coffee may be associated with how its compounds interact with this receptor, which helps protect the body from stress-induced damage."
He added: "When any tissue is damaged, NR4A1 acts to reduce this damage, but in its absence, the problem worsens."
The research team found that several compounds in coffee, including caffeic acid, are capable of binding to the NR4A1 protein and affecting its activity within the cells. Laboratory experiments have shown that these compounds may help reduce cell damage and slow the growth of cancer cells, although these effects disappear when this protein is removed from the cells.
According to the researchers, these findings suggest that part of the health benefits of coffee may be linked to the activation of this receptor, though coffee also affects multiple other biological pathways.
The researchers affirm that the effects of coffee on the body are complex and cannot be reduced to a single mechanism, as there are several receptors and pathways that contribute to these benefits.
They hope that future studies will aid in a deeper understanding of this receptor and the possibility of targeting it with more precise and effective medical compounds.
