Abstract
Juçara is a fruit of ecological and nutritional importance. Its fruits represent an option for the sustainable use of the plant due to its vulnerability to extinction. Thus, the aim of this review was to analyze clinical and experimental studies and highlight the literature gaps regarding the effects of supplementation with Juçara on health. For this scoping review, we consulted the Medline (PubMed), Science Direct, and Scopus databases in March, April, and May 2022. Experimental studies and clinical trials published in the last ten years (2012-2022) were analyzed. Data were synthesized and reported. A total of 27 studies were included, 18 of which were experimental studies. Of these, 33% evaluated inflammatory markers associated with fat accumulation. Most of these studies (83%) used pulp in lyophilized form, and the others (17%) involved juçara extract mixed in water. In addition, 78% of the studies showed positive results with respect to the lipid profile, reduction of oncological lesions, inflammation, microbiota modulation, and improvement in obesity and glycemia-related metabolic complications. Nine clinical trials with results similar to those of experimental trials were found. The majority (56%) were chronic (four to six weeks into the intervention), and 44% were acute. Three offered juçara supplementation in the form of juice, four used freeze-dried pulp, two used fresh pulp, and one used a 9% dilution. The dose was fixed at 5 g, but the dilution ranged from 200 to 450 mL. These trials assessed mainly healthy, physically active, and obese individual adults (19-56 years old), and cardioprotective and anti-inflammatory effects, as well as improvement in the lipid profile and prebiotic potential, were observed. Juçara supplementation showed promising results with respect to its effect on health. However, further studies are needed to clarify these possible effects on health and their mechanisms of action.
