Drinking Coffee May Help You Live Longer

Drinking Coffee May Help You Live Longer

The scientists may finally have an explanation on why people who drink coffee usually live longer that those who don’t. According to Mark Davis, a researcher from the Stanford University, a cup of coffee every day might make the difference.

During the latest study, the scientists analyzed over one hundred people who participated in a study known as the Stanford-Ellison cohort. Furthermore, this study is ongoing, and it aims to reveal how the body functions change during aging.

The experts reviewed many blood samples from the participants, as well as medical records, family histories, and survey data. Based on the study findings, the team established that the levels of IL-1-beta (an inflammatory protein) were higher among the older participants compared with those in the group of the participants who were younger.

In addition to this, the participants with elevated IL-1-beta levels had a higher likelihood of high blood pressure, stiff arteries, and premature death compared to the ones who had lower levels of IL-1-beta.

The 2nd part of the study involved a comprehensive experiment on mice. The researchers wanted to find out whether there was any cause-and-effect link between those conditions and IL-1-beta. After injecting the subjects with elevated levels of the protein, the team observed that the protein triggered hypertension and severe inflammation.

Then, the scientists focused on understanding why some of the older participants had lower levels of the protein. Therefore, they discovered that those participants consumed more beverages containing caffeine.

This means that drinking coffee may prevent the build-up of IL-1-beta. In the last part of the study, the researchers introduced caffeine into human immune cells. It is worth mentioning that those cells also contained the chemical compounds which usually trigger inflammation.

Based on the results, the team concluded that caffeine prevented the chemical compounds from triggering inflammation in human cells. Davis adds that this study is the first which proves that caffeine consumption can be associated with lower blood pressure.

According to the scientists, older people with reduced chronic inflammation have a lower risk of developing stiff arteries, hypertension, and many other cardiovascular conditions. The scientists say they will continue their investigation to find out more about the link between coffee and lower inflammation.
