Pineapple for Anti-Inflammatory

Research suggests that pineapple, and particularly its bromelain enzyme content, has demonstrated meaningful anti-inflammatory activity across a range of study types, including in vitro cell studies, animal models, narrative and systematic reviews, and at least one small randomized controlled trial involving post-surgical patients. The body of evidence, which is largely review-based and mechanistic, indicates that bromelain may reduce pro-inflammatory signaling molecules such as IL-1β, IL-6, and TNF-α, modulate immune cell activity, and lower markers of inflammation, with the 2024 RCT providing some clinical support showing reduced pain and swelling following wisdom tooth extraction compared to placebo. Studies also indicate that other pineapple compounds, including phenolic antioxidants found in the peel, may contribute to these effects, and fermentation of pineapple byproducts appears to enhance their anti-inflammatory properties. However, the evidence base has notable limitations — most findings come from laboratory or review studies rather than large-scale human trials, some reviewed research has mixed conclusions regarding the broader therapeutic applications, and researchers consistently call for more rigorous clinical investigation before firm conclusions can be drawn.
