Diet to Prevent Prostate Cancer: Here’s What You Should Eat

Prostate cancer ranks among the most common types of cancers in men. This is why it is important for men to take the necessary steps to lower their risk of developing this form of cancer. This includes eating foods to prevent prostate cancer. But just how effective is changing your diet when it comes to preventing prostate cancer? And what foods should you eat?

Can the Right Diet Prevent Prostate Cancer?

The idea that our diet can help lower the risk of certain illnesses isn’t new. In fact, eating healthy has been found to generally lower the risk of many illnesses. But for more serious illnesses such as prostate cancer, just how effective would changing your diet be?

Based on studies done on diets and prostate cancer, men diagnosed with prostate cancer who changed to a healthier diet didn’t find any significant effect on their cancer. However, this doesn’t mean that food can’t have an effect, since eating healthy does make our bodies stronger1.

Other studies done on prostate cancer prevention are more promising. The results of these studies2 suggest that eating a healthy diet rich in fruits and vegetables can help lower prostate cancer risk. More research surely needs to be done, but the information that we have right now is promising.

And at the end of the day, there’s really nothing wrong about changing to a healthier diet. Healthy diets lower the risk of heart disease, diabetes, as well as obesity. Plus, studies done on other types of cancers have shown that healthy eating can help lower a person’s risk3. So, eating healthier foods to prevent prostate cancer is well worth the try.

Fish is a good source of protein as well as omega-3, which is a healthy type of fat. Try to lower your intake of red meat, and instead opt for oily fish such as tuna, mackerel, and salmon.


Lastly, tomatoes are a great source of lycopene. Lycopene has been found to be a powerful antioxidant that gets released when tomatoes are cooked. So instead of eating your tomatoes raw, you can try cooking them first to release the lycopene before eating.
