Coffee may have found another purpose than just being a daily pick-me-upper according to a new small study. Cardiovascular health benefits were shown to be the result of moderate coffee drinking according to cardiologist, University of the Ryukyus professor and author of the said research, Masato Tsutsui.
Tsutsui, along with some of his colleagues in Okinawa, performed a test on 27 adults who did not drink coffee on a regular basis and without any health concerns, ranging from 22 to 30 years old. They had to drink a five-ounce cup of caffeinated coffee on one day and the team would measure the drinkers’ left index fingers for hyperemia, a measure of vascular function for the small blood vessels. The process was repeated two days after using decaffeinated coffee.
The results they came up with lead Tsutsui to conclude that caffeine has the potential to improve the functionality of the blood vessels, since the findings registered a 30% increase in the vascular function of the index finger over a 75-minute period for those who drank caffeinated coffee. The heart rate levels for did not change for either of the two, and it also raised the blood pressure and decreased the finger blood flow, albeit, slightly only.
While Tsutsui’s research, which was funded partly by the All Japan Coffee Association, came up with this conclusion, cardiologist Vincent Bufalino, senior vice-president and spokesperson for the Advocate Cardiovascular Institute in Chicago said that further study needs to be done to come up with a solid conclusion because the research was limited to a single cup of coffee only. He also reiterated that higher consumption of caffeinated drinks might have different results. The healthiest option is to drink at most, two cups of coffee per day, as more than that can cause serious health risks, according to another study released last year.
