Top 8 Nuts That May Help Shrink an Enlarged Prostate, Backed by Science


An enlarged prostate, also known as benign prostatic hyperplasia (BPH), affects millions of men as they age. But what if something as simple as a handful of nuts could make a difference in how you feel day to day? While no food is a magic fix, research suggests that certain nuts contain key nutrients that may support prostate health naturally. If you’re looking to snack smarter and support your well-being, these eight powerful nuts might be just what your body needs.

1. Walnuts: The Brain and Prostate Booster

Walnuts aren’t just brain food—they may support your prostate too. Rich in omega-3 fatty acids and antioxidants, walnuts have been studied for their potential to improve urinary function and reduce prostate-specific antigen (PSA) levels.

Why they matter:

  • A 2019 study published in the Journal of Medicinal Food found that men with BPH who ate 75g of walnuts daily experienced improved urinary health and quality of life.
  • Another study in The Journal of Nutrition showed positive changes in prostate health markers.

Try this: Add chopped walnuts to oatmeal, yogurt, or salads.

2. Pumpkin Seeds: Tiny but Mighty

Pumpkin seeds, also known as pepitas, are a zinc-rich snack loaded with antioxidants and magnesium—three things your prostate loves.

What science shows:

  • A 2020 study in the Journal of Medicinal Food found that pumpkin seed oil improved urinary symptoms in men with BPH.
  • Another 2021 study supported these results, linking pumpkin seeds to reduced prostate swelling and discomfort.

Easy ways to eat them:

  • Sprinkle on soups, blend into smoothies, or enjoy by the handful.

3. Pecans: Southern Charm with Health Perks

Pecans are buttery, flavorful, and full of healthy fats, fiber, and powerful antioxidants. They also show promising effects on prostate inflammation.

Backed by research:

  • In a 2014 study, men on a pecan-rich diet showed lowered PSA levels.
  • The antioxidants in pecans may reduce oxidative stress, one of the factors behind prostate enlargement.

Serving idea: Toss into trail mix or bake into whole-grain muffins.

4. Pistachios: Snack Green, Think Clean

Don’t underestimate the power of pistachios. Packed with protein, fiber, and essential nutrients, they’ve been linked to both prostate and overall male wellness.

Findings include:

  • A 2011 study reported that men with BPH who consumed pistachios daily saw significant improvements in urinary function.
  • Other research highlights their role in reducing oxidative stress, which can aggravate BPH symptoms.

Snack tip: Buy them shelled to make portion control easy.

5. Hazelnuts: The Subtle Supernut

Hazelnuts are more than just a spread ingredient. They contain healthy fats, vitamin E, and antioxidants that support cellular health—including in the prostate.

Potential benefits:

  • Studies suggest hazelnuts may help reduce inflammation in the prostate.
  • They also support urinary health in aging men.

Serving idea: Enjoy raw or roasted, or grind them into your own homemade nut butter.

6. Brazil Nuts: A Selenium Powerhouse

These large, creamy nuts are one of the best sources of selenium, a mineral linked to prostate health and immune support.

What the research says:

  • A 2014 study showed that men with high selenium levels had a significantly reduced risk of developing advanced prostate issues.
  • However, moderation is key—1 to 2 Brazil nuts per day is enough.

Tip: Too much selenium can be harmful, so keep servings small.

7. Almonds: Everyday Staple with Big Benefits

Almonds are rich in zinc and vitamin E—two nutrients that may play a role in maintaining a healthy prostate.

According to science:

  • A 2018 study found that zinc reduced inflammation in prostate tissues.
  • Vitamin E has been associated with a lower risk of aggressive prostate conditions.

How to eat them: Raw, roasted, or as almond butter—just watch your portions due to calories.

8. Watermelon Seeds: Don’t Toss Them!

Often overlooked, watermelon seeds are nutrient-dense and contain a plant compound called cucurbitacin, which may have anti-inflammatory effects.

What’s interesting:

  • A 2018 study found that cucurbitacin may help relieve BPH symptoms by reducing inflammation in the prostate gland.

Eat smart: Dry-roast the seeds for a crunchy, mineral-packed snack.

Snack Smart for Better Prostate Health

You don’t need to overhaul your entire diet to make a difference. Simply incorporating 1–2 servings of these nuts into your daily meals could support prostate function and help you feel more comfortable over time. Combine them with a fiber-rich diet, regular exercise, and routine checkups for a well-rounded approach to men’s health.

Quick Tips to Add These Nuts to Your Diet:

  • Mix into morning oatmeal or Greek yogurt
  • Add to smoothies or protein shakes
  • Use nut butters as spreads or dips
  • Top off roasted vegetables or grain bowls
  • Keep a small pack in your bag for convenient snacking
