Introduction
Jaboticaba is a dark-purple fruit that grows directly on the trunks and branches of trees native to the Brazilian Atlantic Forest. Emerging evidence suggests that anthocyanins, ellagitannins, and other bioactive compounds in jaboticaba may influence inflammatory pathways and the gut microbiota, primarily in laboratory and animal studies.1,3,7
This article examines research on jaboticaba phytochemicals and oxidative stress, gut microbiota, and metabolic health, distinguishing preclinical findings from limited human trial evidence.3,6-8
Nutritional profile and bioactive compounds in jaboticaba
Jaboticaba includes Plinia cauliflora and related species native to South America, characterized by dark-purple peel and cauliflorous growth, meaning flowers and fruits develop directly on the trunk and branches.1 Historically consumed fresh or fermented by local populations, this "Brazilian grape" is increasingly being investigated for its pharmacological potential because of its rich content of polyphenols, including anthocyanins and ellagitannins. Jaboticaba peel also contains dietary fiber, phenolic acids, flavonoids, and high-molecular-weight tannins.2
Laboratory and animal studies report antioxidant activity in jaboticaba preparations, including reduced lipid peroxidation markers in some models. Anthocyanins, particularly cyanidin-3-O-glucoside, may contribute, along with ellagitannins and other phenolics.3,4 Some animal studies also report changes in endogenous antioxidant enzymes, including superoxide dismutase (SOD) and catalase.3,5
The jaboticaba peel and seeds contain most of the fruit's phenolic compounds, while the white pulp contains more sugars and lower phenolic concentrations. These differences have encouraged research into whole-fruit processing and peel-derived extracts for functional food development.3
Researchers have investigated jaboticaba preparations for effects on the gut microbiota, glucose metabolism, and endogenous antioxidant defenses.3 Once ingested, parent compounds like ellagitannins exhibit low upper-gastrointestinal absorption and undergo hydrolysis, releasing ellagic acid.
Unabsorbed compounds can reach the colon, where gut bacteria convert ellagic acid into metabolites such as urolithins. Metabolite production and absorption vary among individuals.3

Potential effects on gut health and the microbiome
South American folk medicine has used jaboticaba peel preparations for diarrhea and other gastrointestinal (GI) complaints.3,7 These traditional uses have not been established as effective clinical treatments.
Jaboticaba peel contains dietary fiber and polyphenols with potential prebiotic effects; however, evidence for improved gut health in humans remains limited.3,7 In rats with experimentally induced colitis, jaboticaba peel extract increased Bifidobacterium and Lactobacillus populations and improved some measures of intestinal inflammation.3,7
Animal studies also report increased concentrations of short-chain fatty acids (SCFAs), including acetate and butyrate, following jaboticaba supplementation. These findings suggest a possible link between microbial metabolism and intestinal effects, though they do not establish microbial gene regulation or systemic metabolic benefits in humans.3,7
Emerging in vivo data suggest that jaboticaba derivatives may influence insulin sensitivity and blood lipids in animal models.3 In one study, 36 rabbits were assigned to six groups, including a normal-diet control, a cholesterol-enriched diet group, and groups receiving the cholesterol-enriched diet with jaboticaba peel phenolic extract or simvastatin. Extract supplementation reduced liver fat accumulation and lipid peroxidation.5
A placebo-controlled human trial, described in the supplied FAPESP report, involved 49 adults with obesity and metabolic syndrome. Taking 15 g of jaboticaba peel powder daily for five weeks improved postprandial glucose responses and reduced IL-6, an inflammatory marker.6 These findings concern selected short-term markers, rather than established reductions in diabetes or cardiovascular disease risk.
Anti-inflammatory effects and chronic disease research
Low-grade chronic inflammation is a key feature that contributes to the development of cardiovascular disease (CVD), obesity, and type 2 diabetes (T2D).3,6 In cell and animal studies, jaboticaba preparations have reduced activity or expression of components of the nuclear factor kappa B (NF-κB) signaling pathway and lowered some pro-inflammatory cytokines like interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-alpha (TNF-α).3,7
Researchers have identified the depside jaboticabin in jaboticaba and related species, with higher concentrations in the peel than the pulp or seeds. Laboratory research suggests anti-inflammatory activity; however, evidence for treating chronic obstructive pulmonary disease (COPD) or other human diseases is insufficient.7
A three-week pilot trial in 27 hemodialysis patients tested a jaboticaba peel formulation at 3.3 g/day against routine care. Plasma IL-1β and IL-17E increased significantly in the control group but not in the supplemented group. Though promising, the reported cytokine changes alone do not establish that supplementation worked better than routine care, and the study did not demonstrate kidney or cardiovascular protection.8

How is jaboticaba consumed?
Jaboticaba berries spoil rapidly after harvest, limiting their fresh shelf life to a few days under typical ambient conditions.1,3 Typically, jaboticaba fruits are consumed fresh or made into juices, jams, and fermented products.
Researchers have also developed freeze-dried powders and hydroethanolic extracts, though the chosen preparation method affects phytochemical retention. Steam extraction, for example, can transfer more peel and seed phenolics into juice than mechanical depulping.
High hydrostatic pressure has preserved or increased measured anthocyanin concentrations in some studies, while thermal pasteurization has produced variable results. These processes cannot be ranked universally without accounting for processing conditions.3 The resulting powders and extracts are investigated as ingredients in dairy products, baked goods, and dietary supplements.1-3
Tolerability can also vary by preparation and dose. One acute study summarized in the 2021 review reported diarrhea in 63% of participants after a 20 g dose of a peel-and-seed preparation. This finding should not be generalized to fresh fruit or all jaboticaba products, but it shows why concentrated preparations require separate safety assessment.3
Conclusions
Research on jaboticaba's polyphenols and dietary fiber suggests potential effects on gut microbiota, inflammatory signaling, and metabolic markers. Most mechanistic evidence comes from laboratory and animal studies, whose results cannot be assumed to apply directly to humans.3,7
Small human trials provide preliminary evidence for changes in selected glucose and inflammatory markers, but do not establish jaboticaba as a treatment for chronic non-communicable diseases. Evaluate the effects of fresh fruit, peel powders, and extracts separately; further study is needed to determine effective doses, long-term safety, and clinical outcomes.3,6-8
