A study that included data on more than 47,000 men found that those under the age of 65 who had greater overall plant-based consumption had a significantly lower risk of fatal prostate cancer.
Some research shows plant-based diets may improve disease development risk as well. According to the American Institute for Cancer Research, a large U.S. study found that men following a vegan or strictly plant-based diet were 35 percent less likely to develop prostate cancer. However, only men who followed a strict vegan diet experienced these improved outcomes.
