Is my protein intake harming my prostate

Protein is a vital macronutrient and one of the keys to a healthy, balanced diet, but according to the Dietary Guidelines for Americans, 2020-2025, men ages 19-59 are exceeding their daily recommended protein intake range.

So, when does protein intake become harmful to prostate health? Erica Grace Paulson, MS, RD, a dietician at Loma Linda University Cancer Center, says it's less about the amount of protein and more about the type.

Increased Risk of Prostate Cancer

According to Paulson, studies show that a higher intake of red meats - like beef, pork, lamb, and goat - is associated with a higher risk of prostate cancer. Interestingly enough, high amounts of dairy products, especially whole milk and other highly saturated dairy products, are also associated with an increased chance of prostate cancer.

Foods for Prostate Health

Paulson recommends soy protein and lean proteins such as fish, chicken, and turkey, as they reduce the likelihood of developing prostate cancer and other types of cancer. "I always encourage fish because they're very high in omega-3s, which is good for our brain health, but it is also associated with lower risks of prostate cancer," Paulson says.

She continues, "Even if you have the cleanest diet and take care of yourself, there's still an unfortunate possibility you may develop prostate cancer or other types of cancer." However, some diets are associated with a lower risk of developing cancer. These diets include vegetarian and Mediterranean-style diets that are rich in whole grains, lean protein, and fruits and vegetables.

Protein Supplements

As for protein supplements, Paulson says, "I always tell patients they're called supplements for a reason." The rise of high-protein diets and protein supplements can be linked to the rise of fitness influencers, weight loss trends on social media, and the growing use of GL1P medications.

Adequate protein can be harder to get when you're exercising as much as fitness professionals, but for the general population that's moderately active and able to eat a well-balanced diet, it's not necessary to supplement protein.

Still interested in protein supplements? Consider plant-based proteins such as soy and pea-based proteins. These proteins are just as effective as whey-based proteins and are great for building and maintaining muscle mass.
