Lycopene: How Tomatoes Can Help Prevent Enlarged Prostate (BPH) and Prostate Cancer

Amongst the top 5 foods highest in lycopene, tomatoes are among the richest dietary sources of lycopene, a powerful antioxidant responsible for their bright red color. Over the last two decades, researchers have investigated whether lycopene can help prevent prostate cancer and support prostate health in men with benign prostatic hyperplasia (BPH), commonly known as an enlarged prostate.

The findings are promising!!! 

What Is Lycopene?

Lycopene is a naturally occurring carotenoid found mainly in certain foods such as:

  • Tomatoes
  • Tomato paste
  • Tomato sauce
  • Watermelon
  • Pink grapefruit
  • Guava

Lycopene acts as an antioxidant, helping to neutralize harmful free radicals that may damage cells and contribute to inflammation, aging, and cancer development.

Tomatoes and Prostate Cancer Prevention: What Does Science Say?

A 2013 systematic review and meta-analysis published in the Journal of Nutritional Science and Vitaminology concluded that higher tomato and lycopene intake was associated with a lower risk of prostate cancer. Researchers suggested that lycopene may help protect prostate cells from oxidative damage and abnormal cell growth.

Researchers believe lycopene may work through several mechanisms:

  • Reducing oxidative stress
  • Lowering inflammation
  • Inhibiting abnormal cell proliferation
  • Protecting DNA from damage
  • Supporting normal cell signaling pathways

Although not every study shows the same degree of benefit, the overall evidence suggests that diets rich in tomato products may contribute to a lower risk of prostate cancer.

Considering tomatoes as a treatment for an enlarged prostate (BPH), a systematic review published in Maturitas in 2012 evaluated randomized controlled trials of lycopene for both prostate cancer and benign prostatic hyperplasia (BPH). The study concluded that lycopene may have beneficial effects beyond prevention of BPH and prostate cancer. The study suggests that the lycopene content of tomatoes can help in the treatment of enlarged prostate and prostrate cancer. 

One notable randomized clinical trial gave men with BPH 15 mg of lycopene daily for six months. The researchers found:

  • Reduced PSA levels
  • Less progression of prostate enlargement
  • Improvement in urinary symptoms compared with placebo

These findings suggest that lycopene may help slow the progression of enlarged prostate disease. 

How Best to Prepare Tomatoes for Maximum Lycopene

Why Cooked Tomatoes Are Better Than Raw Tomatoes

Many people assume raw tomatoes are healthiest, but when it comes to lycopene, cooked tomatoes often have an advantage.

The lycopene inside tomato cells is trapped within plant cell walls. Cooking breaks down these structures and makes lycopene easier for the body to absorb.

Research has consistently shown that processed and cooked tomato products provide more bioavailable lycopene than fresh raw tomatoes. From the list of the top 5 foods highest in lycopene, there are presented various ways to prepare tomatoes for maximum lycopene absorption.

Best Ways to Cook Tomatoes for Maximum Lycopene

1. Tomato Sauce with Olive Oil

This may be one of the best methods for increasing lycopene absorption.

Lycopene is fat-soluble, meaning it is absorbed much better when consumed with dietary fat.

A clinical trial found that people who ate tomatoes cooked with olive oil experienced an 82% increase in plasma trans-lycopene levels, significantly higher than those who consumed tomatoes without olive oil. In a layman term, this means one of the best ways to cook tomatoes for lycopene is by cooking it with olive oil.

This is one reason why traditional Mediterranean dishes that combine tomatoes and olive oil are often considered especially beneficial.

Here are a suggested way to prepare tomatoes with olive oil:

  • Simmer chopped tomatoes for 20–30 minutes.
  • Add extra-virgin olive oil.
  • Include onions and garlic for additional antioxidants.
Lightly stir-fried tomatoes in olive oil further improves lycopene bioavailability.

2. Tomato Paste

Tomato paste is highly concentrated and contains large amounts of lycopene.
  • Add to soups, stews, and sauces.
  • Pair with healthy fats for optimal absorption.

3. Slow-Cooked Tomato Stew

Gentle cooking helps release lycopene from the tomato matrix.

4. Mediterranean-Style Sofrito

Sofrito is a traditional Mediterranean cooking method, especially common in Spain, where tomatoes are slowly cooked with olive oil, onions, and garlic.

The ingredients are cooked slowly over low heat until they form a rich sauce.

The idea behind sofrito's potential health benefits is that:
  • Cooking breaks down tomato cell walls and releases more lycopene.
  • Olive oil improves lycopene absorption because lycopene is fat-soluble.
  • Garlic and onions contribute their own beneficial phytochemicals and antioxidants.
A 2019 study from researchers in Spain found that cooking tomatoes with olive oil in a sofrito increased the availability of lycopene and other bioactive compounds. The researchers also observed that some beneficial polyphenols from onions and garlic became incorporated into the tomato matrix during cooking, potentially enhancing their biological activity.

Cooking Method for Sofrito:
  • Heat olive oil over low heat.
  • Add onions and cook until soft.
  • Add garlic and cook briefly.
  • Add tomatoes.
  • Simmer gently for 20–40 minutes.
  • Stir occasionally until thickened.

How Much Tomato Should You Eat?

There is no official dose for prostate health, but studies often use amounts equivalent to:

  1. One serving of tomato sauce daily
  2. A glass of tomato juice
  3. Several cooked tomatoes per day
  4. Approximately 10–30 mg of lycopene daily
Regular consumption appears more important than occasional large servings.

Conclusion 

Current scientific evidence supports the idea that tomatoes and lycopene can contribute to prostate health, particularly in reducing the risk of prostate cancer. Evidence for enlarged prostate (BPH) is encouraging. 

For maximum benefit:
  • Choose red, ripe tomatoes.
  • Cook them rather than eating them only raw.
  • Add olive oil during cooking.
  • Consume tomato products regularly as part of a healthy diet.
While tomatoes are not an absolute cure for prostate disease, they remain one of the most evidence-supported foods for supporting long-term prostate health.
