Methods
The participants were 39 men (mean age=65 years) from the Prostate Cancer Lifestyle Trial (28), a randomized prospective clinical trial determining the effect of diet and comprehensive lifestyle changes on prostate cancer progression. Approval from the Institutional Review Board of the University of California, San Francisco was obtained. The experimental group, which met weekly, followed a very low-fat vegan diet that was supplemented with a fortified soy protein powdered beverage. The group
Conclusions
Results of this study have the following practical implications for nutrition professionals:
- •
Individuals following a very low-fat vegan diet would benefit from nutrition counseling emphasizing well-planned meals and inclusion of fortified plant foods daily to ensure nutrient adequacy, especially for vitamins B-12 and D.
- •
Inclusion of a fortified soy protein supplement in a very low-fat vegan diet provides isoflavones for prostate cancer risk reduction and may aid in ensuring nutrient adequacy.
