Organic coffee contains significantly fewer health-promoting chlorogenic acids than conventionally grown beans, according to a study by scientists at Jacobs University Bremen. Chlorogenic acids are a group of antioxidants that reduce blood pressure and blood sugar, protect cells from reactive molecules, and have anti-inflammatory, antibacterial, and antiviral effects. They are found in many fruits and vegetables, but coffee is the main source in Germany, where adults consume an average of 160 liters per year. The study analyzed 67 roasted coffee samples from different regions of Brazil, including those from conventional and organic plantations. It found that organic coffee beans contained less feruloyl and p-coumaroyl quinic acids than conventional beans, which means they have fewer of these healthy plant compounds.
The researchers are not sure why organic coffee has lower levels of chlorogenic acids, but they speculate that conventionally grown coffee may produce defense compounds against microorganisms, fungi, and bacteria that are beneficial to human health. However, they emphasize that consumers should not avoid organic coffee because of its lower chlorogenic acid content, as the environmental impact of conventional coffee production is much greater. They also note that coffee drinkers can easily compensate for the lower chlorogenic acid levels by drinking an extra cup of coffee per day.
Coffee is not only known for its stimulating effect, but also for its health benefits. Studies have shown that coffee can help with weight loss, reduce the risk of diseases such as multiple sclerosis, and even increase life expectancy. This is due to its secondary ingredients, such as antioxidants and polyphenols, which protect cells from reactive molecules. Chlorogenic acids are particularly noteworthy among these ingredients, as they have a positive effect on the cardiovascular system, reduce blood pressure and blood sugar, and have anti-inflammatory, antibacterial, and antiviral effects. While organic coffee may contain fewer of these beneficial compounds, it is still a healthy choice for consumers who are concerned about the environment.
