The primary objective of this study is to determine if tomato-soy juice can reduce inflammation, which is linked to prostate cancer, in obese males.

Study summary:

The aim of this study is to improve understanding of how diet can ameliorate the state of chronic inflammation. Short term inflammation is an important part of the body's response to injury, but long term inflammation, as happens in the state of obesity, can result in a multitude of secondary problems, like cancer, diabetes, and cardiovascular disease. In males, chronic inflammation is linked to increased risk of prostate cancer. However, men who consume high intakes of tomato or soy products have lower risk of prostate cancer, which may be linked to reduction of chronic inflammation. Using a novel tomato-soy juice, we aim to demonstrate the potential of tomato-soy juice for reducing inflammation in obese adult males.
