Past studies have shown how drinking coffee can reduce the risk of diabetes, but it wasn’t until recently that the focus was turned towards how increasing coffee consumption over a period of years affects the likelihood of developing diabetic symptoms. New research looked at how people who increased their consumption of coffee or tea over a period of four years progressed in their health, and if any associations with diabetes could be detected.
While the study examined health changes over the course of years it also kept track of if wether the coffee consumed was caffeinated or decaffeinated. Participants self-reported through the use of questionnaires that were designed to track the occurrence of any diabetic symptoms.
Results showed that there was 11 percent reduction in the risk of developing diabetes if coffee consumption was increased with an average of more than 1.69 cups a day over the period of 4 years. On the other hand, for participants who decreased their coffee consumption by a cup a day or more over the same period, a increased rate of diabetes was recorded at 17 percent.
Those who consumed three cups or more a day of coffee were labeled “high-stable consumers” and they showed the lowest risk of developing diabetes, which was 37 percent lower than “low-stable consumers,” who consumed one cup or less a day.
For those who drank decaffeinated coffee there was also a lower risk of developing diabetes. However, increasing the consumption of decaffeinated coffee over the period of the study didn’t lower the level of risk, as was observed with caffeinated coffee. Tea drinkers showed no decreased risk in the likelihood of developing diabetes, whatsoever. This lack of statistical data for tea drinking may be associated with the fact there was little increase in the amount of tea consumed among the participants.
The final results were summarized as showing a significant decrease in the development of type 2 diabetes when caffeinated coffee consumption was increased over a period of for years, but not for decafinated coffee or tea.
These changes in the risk of developing diabetes through coffee consumption appeared to occur relatively rapidly. This information shows that besides being a way to enhance alertness coffee has health effects that promote well being and longevity. The added factor of a increase in consumption suggests that coffee’s effect on lowering diabetic risk is dose dependent.
