COLUMBUS, Ohio, July 23 (Nationwide Times) — A special tomato-soy drink, not ordinary tomato juice, may be where any practical takeaway starts for readers.
Ohio State University researchers found that adults with obesity who drank a specially formulated tomato beverage for four weeks had lower levels of three proteins linked to chronic inflammation. The finding suggests that some tomato-based drinks can affect inflammation markers, but the study was small and tested a lab-made product, not a drink most people would buy off the shelf.
What the study found
The research, published in Molecular Nutrition & Food Research and indexed in PubMed, followed 12 adults with obesity in a crossover design. In that type of study, the same participants try more than one intervention at different times, which helps compare results within the group.
Participants drank two 6-ounce servings per day for four weeks. One drink was a specially formulated tomato-soy beverage made from tomatoes bred to contain high levels of lycopene and fortified with soy isoflavones. The comparison drink was a low-carotenoid tomato juice control.
After the tomato-soy drink, the study reported significant decreases in three inflammation-related proteins: IL-5, IL-12p70 and GM-CSF. Another marker, TNF-alpha, trended lower but did not reach the usual threshold for statistical significance.
The study also found that plasma lycopene rose 2.48-fold after the tomato-soy drink, showing that the body absorbed more of the tomato pigment. In addition, the researchers reported shared changes in the urine metabolome, a readout of small molecules in urine, suggesting the tomato effects were not explained by lycopene alone.
Why these proteins matter
IL-5, IL-12p70 and GM-CSF are cytokines, which are small proteins immune cells use to send signals. Doctors and researchers often track them as markers of inflammation. Chronic inflammation is different from the short-term inflammation that helps the body heal after an injury; it can stay elevated over time and is studied for its possible role in several health problems.
What readers should make of it
The most important limitation is size. The study included just 12 adults, so it cannot show whether the drink improves long-term health or whether the same results would appear in a larger, more diverse group.
It also does not show that regular tomato juice has the same effect. The drink in the study was specially designed with extra lycopene and soy compounds. That matters, because the result comes from a formulated product rather than a standard grocery-store beverage.
A separate clue from earlier research
The new findings are not the first time tomato juice has been tied to inflammation markers. A 2013 randomized study indexed in PubMed and conducted at Tehran University of Medical Sciences reported that tomato juice lowered some inflammatory markers in overweight or obese female students compared with water. In that study, the intervention group saw significant drops in IL-8 and TNF-alpha, and IL-6 fell in obese participants.
Taken together, the studies suggest tomato-based drinks may affect inflammation biology. But the Ohio State trial remains an early study, and its results are best read as a sign that the idea deserves more research, not as proof of a new health fix.
