Q: Should patients avoid yeast in their food (i.e., bread) if they have prostate to bone cancer?

A: Though we have addressed yeast in substances, such as the fermented drink Kombucha*, we have not yet addressed yeast in other foods.
There is no contraindication for consuming yeast breads after a cancer diagnosis. In fact, recent research has targeted the effects that the consumption of Baker’s Yeast has on tumor growth in mice. A 2008 study found that yeast treatment in mice led to a decrease in tumor volume dependent on dose and frequency. This research is still in process and would need to be tested in human models.
