COLUMBUS, Ohio, July 23 (Nationwide Times) — A study published in Molecular Nutrition & Food Research found that a specially formulated tomato-soy drink lowered three proteins tied to chronic inflammation in adults with obesity after four weeks.
The takeaway is not that ordinary tomato juice has the same effect. The study used a beverage made from tomatoes bred to contain high levels of lycopene and fortified with soy isoflavones, which means it was much more than a standard grocery-store juice.
What the study tested
The researchers studied 12 adults with obesity. Each person drank two 6-ounce servings a day of either the tomato-soy drink or a low-carotenoid tomato juice control. The trial used a crossover design, with a washout period between the two drinks.
That matters because crossover studies let each participant serve as their own comparison. But this one was still very small, so it can only show an early signal, not a final answer.
What changed in the blood
According to the study abstract, the tomato-soy drink led to significant drops in three cytokines: IL-5, IL-12p70 and GM-CSF. Cytokines are immune signaling proteins. They can help the body respond to injury or infection, but long-lasting changes in these signals are often studied as markers of chronic inflammation.
The study also reported that TNF-alpha moved down, but not enough to meet the usual cutoff for statistical significance.
Another result was a 2.48-fold rise in plasma lycopene after the tomato-soy drink. Lycopene is a carotenoid found in tomatoes.
What the result means
The study points to a possible anti-inflammatory effect from the fortified drink, but it does not prove that the beverage improves long-term health. The research measured lab markers, not outcomes such as fewer heart attacks, less diabetes, or better weight loss.
That is an important difference. A change in a blood marker can be interesting without meaning the drink is a treatment.
The study also found some shared changes in the urine metabolome after both drinks, which the researchers said suggests tomato-driven effects that may be separate from lycopene alone.
Why the drink is not the same as tomato juice from the store
The study’s beverage was specially made. It used tomatoes bred for high lycopene content and was fortified with soy isoflavones. Because of that, the result should not be read as proof that any tomato juice on the shelf will do the same thing.
How this fits with earlier research
A separate 2013 randomized study indexed in PubMed found that tomato juice lowered some inflammatory markers in overweight or obese female students at Tehran University of Medical Sciences. In that study, IL-8 and TNF-alpha dropped in the intervention group, and IL-6 decreased in obese subjects.
That earlier trial is not the same study and not the same group of participants. Taken together, the research suggests tomatoes may have some effect on inflammation markers, but the evidence is still early and limited.
For now, the new Ohio State-related study adds a small piece to the picture: a specially designed tomato drink may change inflammation signals in adults with obesity, but it is too early to treat that as a broad health recommendation.
