| Summary: | Coffee cherry pulp, a major waste product from coffee manufacturing, contains polyphenols with antioxidant activity. However, its clinical safety and health benefits are unclear. This randomized, double-blinded, placebo-controlled trial evaluated the safety and potential efficacy of coffee cherry pulp juice concentrate. A total of 61 participants were randomly divided into a study group (n = 30), receiving the juice, and a control group (n = 31), receiving a placebo drink of 14 g twice daily for 12 weeks. Adverse symptoms, changes in body weight, hematological and biochemical parameters, vital signs, and heart function were evaluated using subject diaries, interviews, blood and urine tests, and electrocardiograms. The results showed no intervention-related adverse events. Body weight, liver, renal function, complete blood counts, blood glucose, urinalysis, and electrocardiograms were not significantly altered throughout the study. Consuming the juice for at least 8 weeks significantly decreased cholesterol and LDL levels. The glucose levels were maintained significantly better than those of the placebo group. The findings suggest that continuously consuming 28 g/day of coffee pulp juice concentrate for 12 weeks is safe in healthy volunteers. Future studies could employ a dose of ≤28 g/day to investigate the efficacy of this novel food, especially for preventing dyslipidemia and diabetes. |
