The prostate is a small gland in the male reproductive system that plays an essential role in producing seminal fluid. As men age, the risk of prostate issues increases, such as benign prostatic hyperplasia (BPH) and prostate cancer. An enlarged prostate may lead to lower urinary tract symptoms, such as increased urinary frequency and a weak urine stream.
Fortunately, certain foods and drinks can affect prostate health positively. This article will delve into foods that shrink the prostate gland and those beneficial for prostate health in general, all supported by scientific evidence.
The Importance of Diet in Prostate Health
Your diet plays a critical role in maintaining a healthy prostate. A balanced diet rich in fruits, vegetables, and healthy fats can reduce the risk of developing prostate cancer and benign prostatic hyperplasia (BPH). Research suggests that such a diet can alleviate BPH symptoms and lower urinary tract symptoms. For instance, a study found that a high intake of vegetables was associated with a 35% lower risk of developing prostate cancer [1].
Foods that shrink prostate gland: Fruits and Vegetables
Tomatoes
Tomatoes are rich in lycopene, an antioxidant that reduces the risk of prostate cancer. Men who consume more tomatoes and tomato sauce have a 19% lower risk of developing prostate cancer [2].
Cruciferous Vegetables
Broccoli, cauliflower, Brussels sprouts, and other cruciferous vegetables—incredibly dark green leafy vegetables that contain sulforaphane—inhibit cancer cell growth. Consuming these vegetables may reduce prostate growth and lower the risk of prostate cancer by 16% [3].
Healthy Fats
Omega-3 Fatty Acids
Found in fish such as salmon, omega-3 fatty acids have anti-inflammatory properties. Men who consume more fish have a 63% lower risk of dying from prostate cancer. Omega-3 fatty acids in a healthy diet can reduce inflammation and manage symptoms of an enlarged prostate [4].
Nuts and Seeds
Almonds, flaxseeds, and pumpkin seeds are good healthy fats and Vitamin E sources. These fats may help reduce BPH symptoms and the risk of prostate issues [5].
Beverages
Green Tea
Green tea contains polyphenols, which have antioxidant properties. Drinking green tea can reduce the risk of developing prostate cancer by 32% and may even help manage symptoms of an enlarged prostate [6].
Pomegranate Juice
Pomegranate juice contains antioxidants beneficial for prostate health. One study found that pomegranate juice prolonged the doubling time of prostate-specific antigen (PSA) levels by about 12 months in men with prostate cancer [7].
The Role of Supplements in Prostate Health
While a balanced diet is essential for maintaining a healthy prostate, dietary supplements can also offer benefits. Supplements such as saw palmetto, zinc, and soy isoflavones are often promoted for prostate health.
Saw palmetto, for instance, has been studied for its potential to manage benign prostatic hyperplasia (BPH) and lower urinary tract symptoms, although results are mixed.
Zinc supplements can support immune system function and may have protective effects against prostate cancer, although excessive zinc can be harmful. Soy isoflavones have shown promise in reducing prostate growth and mitigating the risk of developing prostate cancer. However, it's crucial to consult health professionals before starting any dietary supplements, as they can interact with medications or worsen symptoms in some instances.
The Mediterranean Diet and Prostate Health
The Mediterranean diet, rich in fruits, vegetables, whole grains, and healthy fats like olive oil, has been linked to various health benefits, including improved prostate health.
Studies indicate that this diet can be especially effective in preventing benign prostatic hyperplasia (BPH) and reducing lower urinary tract symptoms. One study found that adhering to a Mediterranean diet was associated with a lower risk of BPH and less severe BPH symptoms.
The anti-inflammatory properties of the Mediterranean diet can also aid in reducing prostate enlargement and may even lower the risk of developing prostate cancer. Olive oil, a staple in the Mediterranean diet, contains antioxidants that may help prevent cellular damage and regulate the inflammatory response, which can affect prostate health.
A simple lifestyle like a Mediterranean diet could benefit your overall health strategy if you want to manage symptoms or reduce risk factors.
Foods and Habits to Avoid
Red Meat and Processed Meats
High consumption of red meat and processed meats like sausages can increase inflammation and worsen benign prostatic hyperplasia (BPH) symptoms. These foods are also risk factors for developing prostate cancer [8].
Saturated Fats
Saturated fats in fast and processed foods can exacerbate urinary tract symptoms and increase prostate enlargement risk [9].
Reflection by a urologist dedicated to prostate care
A balanced diet rich in specific foods like tomatoes, cruciferous vegetables, and fish, as well as beverages like green tea and pomegranate juice, can significantly impact prostate health. Incorporating these foods may help reduce the risk of benign prostatic hyperplasia, BPH and prostate cancer while also helping to manage lower urinary tract symptoms. Always consult with healthcare professionals for personalised medical advice.
