Jaboticaba peel intake improved cognitive performance, inflammatory response, and appetite regulation in healthy adults : a randomized clinical crossover trial
(2025) In Food Research International 221.- Abstract
Jaboticaba (Plinia jaboticaba) is an underutilized Brazilian berry and a source of dietary fiber, cyanidin-3-O-glucoside, and ellagic acid derivatives. Non-clinical studies have shown the potential of jaboticaba to alleviate insulin resistance, low-grade inflammation, and obesity-related cognitive decline, although clinical evidence remains limited. A clinical study was conducted to investigate whether similar effects could be replicated in human subjects following the intake of jaboticaba peel powder (JPP). Nineteen healthy adults (8 men; 11 women; average age 27.5 years and body mass index 24.6 kg/m2) completed a 4-week randomized, controlled, crossover intervention with a 28-day washout period. Participants consumed either... (More)
Jaboticaba (Plinia jaboticaba) is an underutilized Brazilian berry and a source of dietary fiber, cyanidin-3-O-glucoside, and ellagic acid derivatives.

A clinical study was conducted to investigate whether similar effects could be replicated in human subjects following the intake of jaboticaba peel powder (JPP). Nineteen healthy adults (8 men; 11 women; average age 27.5 years and body mass index 24.6 kg/m2) completed a 4-week randomized, controlled, crossover intervention with a 28-day washout period. Participants consumed either 7 g/day of JPP, providing 225 mg of total polyphenols (including 78 mg of cyanidin-3-O-glucoside and 50 mg of ellagic acid), 2.4 g of dietary fiber, and 1.8 g of insoluble fiber, or a matched control containing equivalent sugar and insoluble fiber, blended in water. A standardized carbohydrate-rich meal was also administered. Fasting and postprandial blood samples were collected on days 1 and 28. The interventions did not show a significant effect on postprandial glucose, insulin, adiponectin, or non-esterified fatty acids (p > 0.05). However, fasting and postprandial levels of the proinflammatory cytokine interleukin-6 were 30–40 % lower following JPP consumption (p < 0.05). Additionally, oxidative species decreased by 9 % postprandially (p < 0.01). Furthermore, JPP significantly improved subjective appetite (∼10 %, p < 0.05) and enhanced postprandial selective attention after 45 min (p < 0.05). These findings suggest that jaboticaba peel may provide anti-inflammatory, antioxidant, and cognitive benefits in healthy individuals, supporting its potential as a functional food ingredient.
