Mediterranean Type Diets

ClinConnect Summary

This clinical trial is investigating how different Mediterranean-style diets affect the metabolism of men with localized prostate cancer. Researchers want to understand if these diets, which are often low in carbohydrates and fats, can benefit men who are suspected to have prostate cancer. The study is currently looking for male participants aged 18 and older who have a high suspicion of prostate cancer but have not yet been diagnosed or treated. Participants should have a body mass index (BMI) above 18.5 and must be able to follow the dietary guidelines provided during the study.

If you decide to join this trial, you will be asked to follow a specific diet, and you'll be monitored to see how your body responds. To be eligible, you should not be on certain restrictive diets or have specific medical conditions that might interfere with the study. It’s important that participants can understand English and give their consent to join. This study aims to provide new insights into dietary choices that could potentially improve health outcomes for men facing prostate cancer.
