4 week run-in phase where they are asked to consume a diet low in soy and lycopene, then they will receive the intervention for 4 weeks.

A high lycopene tomato (with levels 2-3x higher than typical) will be grown at OSU farms, as we have done previously. Tomatoes will be harvested and transported to OSU's Food Industries Center (Columbus, OH) for processing into juice and canned using commercial methods. A soy isoflavone extract will be acquired from a commercial supplier, tested for isoflavone content, and dosed into the juice before canning. Our juice recipe has been formulated and previously tested to ensure palatability. Proximate analysis (i.e., the information found on a nutrition facts panel) will be collected from our final juice, along with carotenoid and soy isoflavone levels to fully characterize our intervention agent.

Safety will be evaluated by monitoring adverse events throughout the study. Information will be collected through routine study assessments, including participant interactions, diary entries, vital signs, and standard clinical laboratory testing. Adverse events will be graded using the Common Terminology Criteria for Adverse Events (CTCAE v.5.0). For this study, we define a dose-limiting toxicity (DLT) as the appearance of any adverse event reaching Grade 3-5 toxicity or that otherwise prevents continuation of the intervention.

Adverse events will be graded using established clinical criteria, and the number and severity of events observed during the intervention period will be summarized to determine the rate of dose-limiting toxicities

Participant adherence to the dietary intervention will be monitored using daily self-report diaries, where individuals record how much of the study beverage they consumed each day. These entries will be used to assess overall adherence across the intervention period without disclosing any specific targets or thresholds to participants.

In addition to self-reports, the study will also evaluate biological markers of dietary intake. Levels of compounds derived from the soy components of the beverage (isoflavone metabolites)) will be measured in urine collected before and after the intervention.

Description: In addition to self-reports and assessment of soy metabolites, investigators will also evaluate biological markers of dietary intake. Levels of compounds derived from the lycopene components of the beverage will be measured in plasma collected before and after the intervention.

Changes in circulating inflammatory markers will be evaluated before and after the dietary intervention. Concentrations (pg/mL) of key markers (Interleukin-5, Interleukin-1beta, Tumor Necrosis Factor-alpha) will be measured using standard laboratory techniques to characterize overall shifts in inflammation-related signaling. The analysis will help determine whether the intervention is associated with measurable changes in the body's inflammatory profile over time.

Physical activity will be evaluated at two points during the study using a validated wearable activity monitor. The amount of daily activity, expressed in minutes, will be analyzed as a continuous measure. This assessment provides an estimate of both sedentary behavior and ambulatory movement in real-world settings, allowing us to characterize overall patterns of physical activity during the trial.
