COLUMBUS, Ohio, July 23 (Nationwide Times) — A tomato drink may sound like a simple health fix, but the new research behind it is more limited than that. A study published in Molecular Nutrition & Food Research found that adults with obesity who drank a specially formulated tomato-soy beverage for four weeks had lower levels of three proteins linked to chronic inflammation. The result is encouraging, the study suggests, but it does not show that ordinary tomato juice has the same effect or that the drink prevents disease.
What the study found
The research tested 12 adults with obesity. One group drank a tomato-soy beverage, and the other got a low-carotenoid tomato juice control. Participants drank two 6-ounce servings a day for four weeks, then went through a washout period and switched treatments in a crossover design.
After the tomato-soy drink phase, the study reported significant drops in three cytokines: IL-5, IL-12p70 and GM-CSF. Cytokines are signaling proteins that help direct immune activity. When they stay elevated, they can be part of ongoing, low-grade inflammation.
The paper also found that TNF-alpha trended downward, but the change did not meet the usual standard for statistical significance.
Why this drink was different from regular tomato juice
This was not a store-bought tomato juice study. The beverage was made from tomatoes bred to contain high levels of lycopene and was fortified with soy isoflavones, which are plant compounds found in soy.
That matters because the formula was designed to test whether tomato compounds, and possibly the soy add-in, could affect inflammation markers. The study also found blood lycopene levels rose 2.48-fold after the tomato-soy drink, showing the body absorbed more of the tomato pigment.
What the results do — and do not — mean
The main takeaway for a normal reader is caution, not a new diet rule. The study involved only 12 people, so it is too small to support broad recommendations. It also measured biomarkers, not real-world outcomes such as heart attacks, diabetes, or long-term weight change.
The paper did find some shared changes in the urine metabolome after both interventions, which suggests some tomato-related effects may not depend on lycopene alone. But that still does not mean the drink has been proven to improve health in a lasting way.
Has tomato juice been studied before?
Yes, but in a different and separate study. A 2013 randomized trial indexed in PubMed looked at overweight or obese female students at Tehran University of Medical Sciences. That study found tomato juice reduced some inflammatory markers compared with water, including lower IL-8 and TNF-alpha in the intervention group. In obese participants, IL-6 also decreased.
That earlier work and the new Ohio State-linked research point in the same direction: tomato-based drinks may influence inflammation markers. Still, both studies were small, and neither is enough on its own to prove a long-term health benefit.
For now, the research is best read as early evidence that certain tomato compounds may affect the body’s inflammation signals. It is not proof that tomato juice is an anti-inflammatory treatment.
