COLUMBUS, Ohio, July 23 (Nationwide Times) — A special tomato-soy drink may help lower some signs of chronic inflammation in adults with obesity, according to a study published in Molecular Nutrition & Food Research by Ohio State researchers.
For most people, the practical takeaway is simple: this was not ordinary tomato juice, and it is far too early to call it a treatment. The study was small, short, and measured blood markers, not long-term health outcomes. Still, it adds to evidence that tomato-based foods can affect inflammation-related biology in the body.
What did the study find?
The study followed 12 adults with obesity. Participants drank either the special tomato-soy beverage or a low-carotenoid tomato juice control for four weeks, then switched after a washout period in a crossover design, according to the published abstract on PubMed.
After the tomato-soy drink, researchers reported significant drops in three proteins tied to chronic inflammation: IL-5, IL-12p70 and GM-CSF. TNF-α also trended downward, but the change did not meet conventional statistical significance.
The same study found that plasma lycopene rose 2.48-fold after the tomato-soy drink. It also reported shared changes in the urine metabolome after both interventions, which the researchers said suggests some tomato-related effects may happen even beyond lycopene alone.
Was this just tomato juice?
No. The beverage was specially made from tomatoes bred to contain high levels of lycopene and was fortified with soy isoflavones, according to the study abstract.
That matters because the drink used in the trial is not something most people would buy off a shelf or make at home. Fox News quoted the researchers as saying it was “not a beverage consumers can easily recreate at home.”
What do the results mean for daily life?
The study suggests that a tomato-based drink with added compounds may change inflammation markers in people with obesity. But it does not show that the drink prevents disease, replaces treatment, or should be treated as a proven health fix.
The sample size was just 12 adults, and the study lasted four weeks. Fox News quoted a source saying the study was “too small to draw broad conclusions about long-term health effects.”
That is why the findings are best seen as early-stage research, not a new diet rule.
Why do scientists care about inflammation markers?
Inflammation is the body’s immune response to injury or infection. When it stays switched on for too long, it is linked with a higher risk of many chronic health problems.
The proteins measured in the Ohio State study are called cytokines. They help immune cells communicate. In this study, the researchers looked at whether the tomato-soy drink changed those signals in ways that might point to less inflammation.
Has tomato juice been studied before?
Yes. A separate 2013 randomized study published on PubMed looked at tomato juice in overweight or obese female students at Tehran University of Medical Sciences. That study reported decreases in some inflammatory markers, including IL-8 and TNF-α in the intervention group, and IL-6 in obese subjects.
That earlier study is not the same as the Ohio State trial, but it does show that tomato products have been studied for possible effects on inflammation for more than a decade.
The bottom line
The Ohio State study adds a new clue: a specially designed tomato-soy drink was linked with lower levels of three inflammation-related proteins in a small group of adults with obesity.
But the evidence is still early. The trial was small, short, and focused on biomarkers, so it does not prove a broad health benefit for the public. For now, it is best understood as a promising research result, not a prescription.
