A recent study published in the journal Cancer Epidemiology, Biomarkers & Prevention suggests that high nitrate intake, as a result of exposure to nitrites from water and chlorination, may be linked to an increased risk of aggressive prostate cancer.
The study, conducted by researchers at the University of California, San Francisco, analyzed data from over 47,000 men who participated in the Health Professionals Follow-Up Study between 1986 and 2012. The men completed food frequency questionnaires every four years, which allowed researchers to estimate their nitrate intake.
Over the course of the study, 5,847 men were diagnosed with prostate cancer, including 1,051 cases of aggressive prostate cancer. The researchers found that men who consumed the highest levels of nitrate were 21% more likely to develop aggressive prostate cancer than those who consumed the lowest levels.
The study also found that men who consumed high levels of nitrate from processed meats, such as bacon and sausage, were at an even higher risk of aggressive prostate cancer. This suggests that the source of nitrate may play a role in the increased risk.
While the study does not prove causation, it does suggest a potential link between nitrate intake and prostate cancer risk. The researchers suggest that more studies are needed to confirm these findings and to determine the underlying mechanisms behind the association.
So, what should you do if you are concerned about the potential link between nitrate intake and prostate cancer risk? First, it is important to maintain a balanced and healthy diet that includes a variety of fruits, vegetables, whole grains, and lean protein sources. While nitrate-rich foods may have potential health benefits, they should not be the only focus of your diet.
It is also important to limit your intake of processed meats, such as bacon and sausage, which have been linked to a variety of health issues, including an increased risk of cancer. If you do choose to eat processed meats, look for products that are low in nitrates and nitrites, or choose leaner alternatives such as turkey bacon or chicken sausage.
If you have any questions or concerns about your prostate health, talk to your healthcare provider who can help you understand the risk factors. Or book a consultation with one of our ND’s who can develop a plan to help you maintain optimal health.
