The University of Sydney's scientists, under the leadership of Dr. Llew Mills, delved into the influence decaf coffee exerts on habitual caffeine coffee drinkers. Their findings were remarkable, showing that caffeine isn't always the prime factor in coffee addiction. The study participants discovered a delicious strategy to combat addiction: coffee itself.

Are you addicted to coffee or just caffeine?

The study involved 61 individuals who identified themselves as "habitual caffeine coffee drinkers" (consuming at least three cups a day). After 24 hours without their favorite beverage, they were divided into one of three groups. The first group was provided with plain water, while the second group received decaf coffee and was informed about it. Surprisingly, the third group, also served decaf coffee, was misled to believe they were drinking regular coffee.

Forty-five minutes after downing the drinks, withdrawal symptoms were evaluated, and participants were asked to share their overall experiences. Interestingly, the group who thought they were drinking "regular" coffee reported feeling the best. A significant reduction in caffeine withdrawal symptoms such as headaches, fatigue, and irritability was observed in these participants.

Decaf coffee can also alleviate withdrawal symptoms

The group who thought they were drinking caffeinated coffee, but was instead served decaf, suggests the placebo effect may be in play, as indicated by the University of Sydney scientists in an official press release. Expected relief from drinking what was believed to be caffeinated coffee was actualized, primarily because they were oblivious of what they were actually given. The crux of the matter - taste - left no suspicion that they were consuming coffee.

However, the reaction of those who knew they were drinking decaf coffee was even more intriguing. In this group, an open placebo effect emerged, arising from years of established habits and associations. Decaf coffee retains the sensory attributes (taste and smell) of "regular" coffee, leading to significant effects even when they were not anticipated - a result of associating the taste of the drink with their regular habit.

Insights from the study could help tackle addiction

The study's proponents argue that the insights gleaned can aid treatment for a wide range of addictions. Regarding coffee, Dr. Mills argues that a cup of decaf coffee can play a proactive role in managing caffeine intake by warding off severe cravings. Moreover, these findings suggest that the inclination towards caffeinated versions might not necessarily stem from a potential addiction to it, but rather from an acquired taste for the aroma and flavor of the beverage.

The findings of this research can potentially lead to devising more effective treatment mechanisms for addiction in the future. They demonstrate that for many, the love of coffee might not stem from the caffeine it contains, but simply from the sensory experiences linked with its consumption.
