Tomato-Soy Juice May Reverse Chronic Inflammation in Just 4 Weeks: New Study Findings

A new clinical study suggests that a specially formulated tomato-soy juice—rich in lycopene and soy isoflavones—may help reduce markers of chronic inflammation in adults with obesity after just four weeks of daily consumption. The findings, published by researchers at The Ohio State University, highlight the potential of functional foods to modulate inflammation, a key driver of obesity-related health complications.

The study, detailed in a May 30, 2026, release from Ohio State University, involved healthy adults with obesity who consumed the tomato-soy juice daily. Compared to a control group drinking a standard tomato juice without the added compounds, those in the experimental group showed significant reductions in three key inflammatory proteins in their blood. The researchers emphasized that the beverage’s natural plant compounds—lycopene (found in tomatoes) and soy isoflavones—appeared to drive these effects, which were not observed in the control juice.

“The idea is, can we use food-based interventions to modulate inflammation?” said Jessica Cooperstone, associate professor of horticulture and crop science at The Ohio State University and lead author of the study. While the findings are preliminary, they align with broader research suggesting that dietary interventions could play a role in managing chronic inflammation, a process linked to conditions such as cardiovascular disease, diabetes, and metabolic syndrome.

The study’s focus on inflammation is particularly relevant given the rising global prevalence of obesity, which is associated with low-grade systemic inflammation. Chronic inflammation is implicated in the progression of numerous obesity-related diseases, making dietary strategies to mitigate it a promising area of research. However, the study’s authors note that further research is needed to determine the long-term efficacy and safety of such interventions, as well as their potential applications in clinical settings.

While the tomato-soy juice showed promise in this small-scale study, We see not yet clear whether the effects would be sustained over longer periods or applicable to broader populations. The researchers also acknowledged that individual responses to dietary interventions can vary widely, and factors such as overall diet, lifestyle, and genetics may influence outcomes.

This study builds on previous research exploring the anti-inflammatory properties of lycopene and soy isoflavones. Lycopene, a carotenoid found in tomatoes, has been studied for its antioxidant and anti-inflammatory effects, while soy isoflavones have been linked to cardiovascular and metabolic benefits. However, most prior research has focused on these compounds in isolation or as supplements, rather than in a combined, food-based format.

The Ohio State University study was published in a peer-reviewed journal, though the specific journal name was not provided in the available reporting. The findings were also highlighted by ScienceDaily and NDTV, though these outlets did not provide additional details beyond the original research.

For individuals with obesity or chronic inflammation, the study offers a cautious but encouraging glimpse into the potential of dietary modifications. However, experts advise against interpreting these results as a definitive solution or replacement for established medical treatments. As with any dietary intervention, consultation with a healthcare provider is recommended before making significant changes to one’s diet.

Moving forward, researchers plan to explore whether the tomato-soy juice could be adapted for specific health conditions, such as metabolic syndrome or autoimmune disorders, where inflammation plays a central role. They also aim to investigate the mechanisms by which the juice exerts its effects, including its impact on gut microbiota and metabolic pathways.
