A specially formulated tomato-soy juice lowered several markers of inflammation in adults with obesity after four weeks of daily consumption. The beverage, rich in lycopene and soy isoflavones, outperformed a control tomato juice in a small clinical trial led by researchers at The Ohio State University.
Twelve healthy adults with obesity participated in the study. They drank two 6-ounce cans of the tomato-soy juice each day for four weeks, followed by a washout period and then four weeks of a low-carotenoid control juice. Blood samples showed significant reductions in the cytokines Interleukin-5, IL-12p70 and granulocyte-macrophage colony-stimulating factor after the tomato-soy juice phase, while the control produced no comparable changes.
