COLUMBUS, Ohio, July 23 (Nationwide Times) — A specially formulated tomato drink lowered several inflammation-related proteins in adults with obesity in a small Ohio State University study published in Molecular Nutrition & Food Research.
For most readers, the practical takeaway is simple: the research points to a lab-tested beverage, not to standard tomato juice or a do-it-yourself health drink. The study used tomatoes bred to contain high levels of lycopene and added soy isoflavones, ingredients that were part of the formula the researchers tested.
What the study found
The trial included 12 adults with obesity. Participants drank either the tomato-soy beverage or a low-carotenoid tomato juice control, with two 6-ounce servings a day for four weeks. The study used a crossover design with a washout period between interventions.
After the tomato-soy drink, the researchers reported significant decreases in three proteins tied to inflammation: IL-5, IL-12p70 and GM-CSF. Another marker, TNF-α, moved downward but did not meet the usual threshold for statistical significance.
The study also found plasma lycopene rose 2.48-fold after the tomato-soy beverage. In urine testing, both drinks produced some shared metabolic changes, which the researchers said suggests some tomato-related effects may not depend only on lycopene.
What these proteins mean
Cytokines such as IL-5, IL-12p70, GM-CSF and TNF-α are proteins that help immune cells communicate. They can rise during inflammation, which is part of the body’s normal defense system. Chronic inflammation, however, is linked with a range of long-term health problems.
This study does not show that the drink treated disease or changed long-term health outcomes. It shows changes in biomarkers, which are signals measured in blood or urine.
Why the result should be read cautiously
The study was very small, and the researchers looked at short-term changes over four weeks. That means the findings are preliminary, and they do not prove that the drink would help a broader group of people over time.
Fox News, summarizing the study, quoted a researcher saying the beverage contained concentrated amounts of lycopene and soy isoflavones and was not something consumers could easily recreate at home. The same coverage noted that larger studies are needed before broad dietary recommendations can be made.
How this fits with older research
The Ohio State study is not the first to look at tomatoes and inflammation. A 2013 randomized study indexed in PubMed found that tomato juice reduced some inflammatory markers in overweight or obese female students at Tehran University of Medical Sciences. In that trial, IL-8 and TNF-α fell in the intervention group, and IL-6 decreased in obese subjects.
That earlier study, like the newer Ohio State one, suggests tomatoes may affect inflammation-related markers. But the two studies used different people, different drinks and different designs, so they should not be treated as the same result.
The bottom line
The new study adds to evidence that a specially formulated tomato beverage can change inflammation markers in people with obesity. But because the trial was small and short, the result is better seen as a research clue than as a reason to change diets based on ordinary tomato products alone.
