Synopsis

Source of validity: Scientific
Rating (out of 5): 3

The Brazil nut is notably high in selenium, a trace mineral essential for human health. Selenium has been investigated for its role in supporting prostate health, particularly because low selenium status has been associated in some studies with an increased risk of prostate cancer. Several observational studies and meta-analyses have explored the potential protective effect of selenium against prostate cancer, with mixed results. Some research suggests that adequate selenium intake may reduce the risk of prostate cancer or slow its progression, while other large, well-conducted clinical trials, such as the SELECT (Selenium and Vitamin E Cancer Prevention Trial), have not shown a significant protective effect of selenium supplementation for prostate cancer prevention.

Brazil nuts are one of the richest natural sources of selenium, and consuming them can significantly increase selenium levels in the body. This nutritional property is the primary reason Brazil nuts are sometimes recommended for supporting prostate health. However, excessive selenium intake can be harmful, so moderation is important.

In summary, there is scientific rationale—though not unequivocal support—for the use of Brazil nuts (due to their selenium content) in promoting prostate health. The evidence is moderate, with some studies showing benefit and others showing no effect. There is little to no tradition of using Brazil nuts specifically for prostate health outside of their nutritional value.
