COLUMBUS, Ohio, July 23 (Nationwide Times) — A small study suggests that a very specific tomato drink may lower some signs of chronic inflammation in adults with obesity. But the finding is early, and it does not mean a regular glass of tomato juice is a proven health fix.
What the study found
Researchers reported that adults with obesity who drank a specially made tomato-soy beverage for four weeks had significant drops in three proteins linked to inflammation: IL-5, IL-12p70, and GM-CSF. Another marker, TNF-α, went down but did not meet the usual standard for statistical significance. The study also found that blood lycopene levels rose 2.48-fold after the tomato-soy drink.
In plain terms, the drink was associated with lower inflammation signals in the blood. The study did not show whether people felt better, lost weight, or had fewer health problems over time.
What was in the drink
This was not ordinary tomato juice. The study described a beverage made from tomatoes bred to contain high levels of lycopene and fortified with soy isoflavones. Participants got two 6-ounce servings a day. They drank the test beverage for four weeks, then went through a washout period as part of a crossover design.
A crossover study means the same participants try both drinks at different times, which can help researchers compare the effects more directly. In this case, the comparison drink was a low-carotenoid tomato juice control.
Why this matters for everyday choices
For most people, the main takeaway is caution, not a new rule. The study involved just 12 adults, so it is far too small to prove long-term benefits or support broad dietary advice. It also tested a specially formulated product, not a standard grocery-store juice.
That means the result is interesting science, but not a reason to treat tomato juice as medicine. It may add to research on how plant compounds such as lycopene and soy isoflavones affect the body, but it does not settle the question of whether drinking tomato juice can meaningfully improve health for most people.
What inflammation markers are
Inflammation is the body’s response to injury or infection. When it becomes long lasting, it can be linked to chronic disease. The proteins measured in this study are part of the body’s immune signaling system. Researchers often track them because changes can suggest shifts in inflammation, even when a person does not feel any different right away.
The study’s urine results also pointed to a possible tomato-driven effect beyond lycopene alone. Researchers reported shared changes in the urine metabolome, which is the mix of small molecules the body makes and breaks down.
Has tomato juice been studied before?
Yes. A separate 2013 randomized study, published in PubMed and done at Tehran University of Medical Sciences, found that tomato juice lowered some inflammation markers in overweight or obese female students. In that study, IL-8 and TNF-α fell in the intervention group, and IL-6 decreased in obese participants.
That earlier work and the new study point in the same general direction, but they were done in different groups and should not be mixed together. Both are still small studies, so larger trials would be needed before anyone could draw strong conclusions about everyday use.
