Systematic Literature Review of Functional Snacks: Bioactive Properties, Food Technologies, and Consumer Acceptance.
Review in Foods (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Functional foods containing antioxidants and anti-inflammatory compounds are a promising nutritional intervention. However, significant gaps remain in the literature on the development and evaluation of functional snacks for improving health outcomes. This systematic literature review (SLR) aimed to summarize the existing evidence on the development of enriched functional snacks containing bioactive ingredients, with a particular focus on their potential relevance to mental health. The review also examined food technologies, consumer acceptance, current knowledge gaps, and priorities for future research. The SLR was conducted in accordance with the PRISMA guidelines. PubMed, Scopus, and Web of Science were searched for studies on snacks and functional foods published between 2020 and 2025. Original studies evaluating functional snacks and/or bioactive compounds with neuroprotective, anti-inflammatory, or antioxidant properties were included. The initial search yielded 281,118 records. Following screening and quality assessment, 22 articles were selected through a three-author consensus process. Among the included studies, 12/22 focused on product development and antioxidant activity. Three studies included in vivo evaluations, while four included in vitro assessments of anti-inflammatory or antioxidant effects. Technologies such as extrusion, nanoencapsulation, and freeze-drying were employed to protect bioactive compounds and preserve bioactivity. Only two studies included sensory evaluation, with both reporting preliminary evidence of high acceptability. Overall, the SLR revealed limited evidence on functional snacks, particularly regarding their effects on mental health. Significant gaps remain in biological, neuroprotective, and sensory validation. Further studies are needed to establish the efficacy, biological effects, and consumer acceptability of enriched functional snacks, as well as consumer acceptability across diverse, relevant target populations.
