Prostate Health & Nutrition

Before reviewing oatmeal’s role in prostate health, it’s important to understand the relationship between diet and prostate health.

Nutrition plays a significant role in prostate health. Foods can either help or worsen prostate conditions. Additionally, proper nutrition can help prevent certain issues in the prostate gland.

We’re going to specifically focus on prostate cancer for this post.  

It is worth noting that a healthy diet is recommended for those with an enlarged prostate and frankly, the general population.  

Dietary interventions can reduce risk of prostate cancer and slow down progression. On top of that, foods can help during treatment and reduce recurrence. 

An overall healthy diet can help lower PSA levels, optimize treatments, and promote overall health– decreasing chance of chronic disease.

For optimal prostate health, you should include certain foods regularly. On the flip side, some foods should be limited. 


  • Whole Grains (oats, whole wheat bread)
  • Healthy Fat/Omega 3 Fatty Acids (avocado, fish)
  • Fruits and Vegetables 

Limit Intake: 

  • Processed Foods (microwave meals, chips)
  • Processed Meat (bacon, deli meat) 
  • Foods High in Saturated Fat (fried food, butter)  
  • Baked Goods (cookies, muffins, cakes)

Stages of Prostate Cancer

Next question, is oatmeal good for prostate cancer?

Everyone goes through a different journey when it comes to cancer. Each diagnosis and treatment plan is unique. 

There is limited research specifically investigating oatmeal’s relationship to prostate cancer. However, we do know a lot that can be connected.

Oatmeal is a great addition to a healthy diet while eating for prevention and reduced progression. As stated previously, healthy eating can decrease chance of prostate cancer.

You can also add oats to meal plans during treatment or in recovery.

It’s essential to consult with healthcare professionals for personalized advice and to incorporate oatmeal as part of a comprehensive approach to prostate health.


If your goal is to prevent prostate cancer, oats can be a part of your diet plan. They may lower prostate cancer risk due to their several phenolic compounds.

Rich in dietary fiber, antioxidants, and essential nutrients, oatmeal offers a multifaceted approach to supporting prostate and overall health. 

Plus, there is a link between the soluble fiber in oatmeal, specifically beta-glucans, and lowering cholesterol levels. This indirectly benefits the prostate by promoting overall cardiovascular well-being.

Moreover, oatmeal contains phytochemicals like lignans and avenanthramides, which possess anti-inflammatory and antioxidant properties.

Chronic inflammation has been associated with an increased risk of various cancers, including prostate cancer. By mitigating inflammation and neutralizing harmful free radicals, oatmeal contributes to a potentially protective environment against prostate cancer development.

Overall, oatmeal is a great addition to a healthy diet. Of course, eating oatmeal daily cannot guarantee prostate cancer prevention. However, studies show many benefits to oatmeal including promoting heart health and decreasing chance of chronic disease. Plus, there is a connection between a heathy diet and lifestyle and decreased cancer risk.

Reduce Progression

A balanced diet can help decrease prostate cancer progression. After diagnosis, many patients are instructed to make diet adjustments. Oats can be a part of this new diet plan.

Forming overall healthy habits, including eating plant based foods (like oats), is recommended once diagnosed with prostate cancer.

Emerging research suggests oats might play a role in slowing the progression of prostate cancer.

Oatmeal is a whole grain powerhouse with a high fiber content. The fiber in oatmeal has been associated with regulating blood sugar levels and maintaining a healthy weight, factors that may indirectly influence prostate cancer progression.

Additionally, a study showed a lower incidence of high grade prostate cancer with low total cholesterol for those in the active surveillance stage. It is well known that including oatmeal regularly can help lower cholesterol.

Recent studies show a correlation between insulin resistance and prostate cancer. Luckily, eating oatmeal may improve insulin resistance.

Furthermore, oatmeal’s anti-inflammatory and antioxidant content could help create an environment less conducive to cancer cell growth and proliferation. 

While oatmeal alone cannot be considered a definitive solution, its incorporation into a diet rich in a variety of cancer-fighting foods and a healthy lifestyle can contribute to an overall strategy for managing prostate cancer progression.


During prostate cancer treatment, oats can be a part of your meal plan.

If you have a decreased appetite, oatmeal can provide various nutrients in one meal. However, they may fill your stomach and can possibly cause abdominal pain due to their high fiber content. 

If oats are tolerable, they are a great addition. I recommend adding fruits and nuts to create a more nutrient dense meal during this time. 

If oats are intolerable, don’t consume during your treatment timeframe.

Finally, if you are experiencing constipation, oats are an incredible resource to resolve this issue.

The importance of adequate nutrition in the survivorship stage of prostate cancer cannot be overstated. Food can be used as a tool to lower risk of cancer recurrence and promote quality of life.

Moreover, nutrition can help increase energy, regain strength, and hopefully bring you back to where you were pre-treatment. 

It’s recommended to regularly consume fruits, vegetables, lean protein, healthy fat, and whole grains. Although oatmeal doesn’t have to be your main source of whole grains, it is important to incorporate whole grains into your diet plan after treatment for prostate cancer.

As stated previously, oatmeal, a nutritious whole grain, contains essential nutrients and antioxidants, such as beta-glucans, avenanthramides, and lignans.

Researchers have linked these bioactive compounds to anti-inflammatory and antioxidant effects that may contribute to creating an unfavorable environment for prostate cancer. In turn, helping reduce chance of reoccurrence.

 Oatmeal can be apart of the prevention, surveillance, treatment, and survivorship stage of prostate cancer. 


Oatmeal Health Benefits

Whether you’ve recently received a prostate cancer diagnosis or are working on prevention, oatmeal has a place in your meal plan.

Even if we haven’t fully established the relationship between oatmeal and cancer, we have proven that oatmeal can promote overall health, which is the bigger picture.

In other words, the benefits of oatmeal extend beyond prostate health.

First, oats are a whole grain and contain protein, lipids, carbohydrates, vitamins, minerals, and phytochemicals. They are a great source of dietary fiber.

Oat also provides micronutrients such as vitamin E, folate, zinc, iron, selenium, copper, manganese, carotenoids, betaine, choline, sulphur containing amino acids, phytic acid, lignins, lignane, and alkyl resorcinols.

Oats may help prevent cardiovascular disease, reduce blood glucose, promote gut health, boost immune function, and help prevent cancer.

Beta Glucan

As stated above, oatmeal contains beta glucan.

Beta glucan is a powerful fiber. It is the major active compound in oats with proven cholesterol-lowering and antidiabetic effects. It can also promote a healthy digestive tract.

This fiber acts as a defense mechanism against various pathogens. There is an association between beta glucan and prevention of diseases like cancer, stroke, and coronary heart diseases.

Heart Health

The biggest benefit of consuming oats is the effect on heart health. Oats can lower cholesterol and support a healthy blood pressure.

Research demonstrates that incorporating beta glucan rich oats or oat-derived products into one’s diet can notably reduce both blood lipid levels and blood pressure through the regulation of insulin metabolism in individuals with mildly elevated cholesterol.

Regular consumption of oat is associated with a decreased risk of cardiovascular disease. Additionally, eating oats can reduce risk of atherosclerosis due to their anti-inflammatory properties.

Finally, their low glycemic index makes oats an excellent choice for stabilizing blood sugar levels, further contributing to heart health.


Next, oats are beneficial for diabetes and blood sugar management.

The beta glucan in oats can help control blood sugar levels after eating. This substance slows down how our bodies break down food and absorb sugar. It’s like a kind of fiber that makes our stomach feel full, so we don’t absorb sugar too quickly.

The effectiveness depends on how you prepare it, how much you eat, and in what form you consume it. Different types of oats have different effects on blood sugar levels. Some types of oats are better for managing blood sugar than others.

In general, oats can be consumed for diabetes prevention and maintenance.

Weight Management

Studies show that the intake of dietary fiber and whole grains can lower body weight.

Oats can provide satiety and reduce hunger. In other words, oats can fill your stomach longer leading to decreased intake of other foods.

Oats can also reduce gastric emptying which can decrease overall body weight, body fat, BMI, and central adiposity. Finally, oat beta glucan can activate the gut hypothalamic axis and increase satiety.


Studies have shown a connection between the compounds found in oats and reduced risk of cancer. Specifically, oats have been shown to reduce risk of skin, colon, and lung cancer. 

Furthermore, researchers have found that saponins, which are present in oats, effectively inhibit the growth of colon cancer cells.

The antioxidant properties of compounds found in oatmeal may mitigate oxidative stress, which can contribute to cancer development.

Oat is rich in antioxidants such as vitamin E, phytic acid, phenolic compounds, flavonoids, sterols, and avenanthramides. Vitamin E prevents premature aging, chronic disease, cancer, cardiovascular disease, and strokes by acting as an antioxidant.

Gut Health

The gut microbiome has been gaining a lot of attention in recent years. This is where the microorganisms live in the digestive tract.

The gut microbiota is important for proper gastrointestinal health and can help prevent disease. Whole oat contain phytochemicals which can promote gut health leading to better digestion and overall health. Oats also have a bulking effect, further helping digestion. Plus, the resistant starch in oats supports gut health.

To conclude, oats offer various benefits including supporting heart health, blood sugar, weight management, gastrointestinal health and helping prevent cancer.

Choosing Oatmeal

Choosing the right oatmeal depends on your personal preferences and dietary needs.

When searching for the best oatmeal, I’d recommend plain oats. These typically come in a larger canister. With plain oats, you can adjust to your own taste preferences and prepare as you like. 

Some oatmeal is very high in sugar and is not the healthiest choice. Typically, these are prepackaged single servings.

Different types of Oatmeal:

  • Rolled Oats/Old Fashioned Oats: Partially cooked and flattened, making them quicker to prepare than steel-cut oats while retaining some texture and nutrition.
  • Instant Oats: Pre-cooked and flattened into thin flakes, resulting in the quickest cooking time. However, they may have lower nutritional value and may contain added sugars or flavors. 
  • Steel Cut Oats: The least processed oats and have a chewy texture. They take longer to cook but offer a nutty flavor and are higher in fiber.


  • Ingredients: Check the ingredient list for any additives, such as sugar, artificial flavors, or preservatives. Ideally, choose oats with minimal ingredients.
  • Sugar Content: If you prefer sweetened oatmeal, choose options with lower added sugar or consider using natural sweeteners like honey, cinnamon, or maple syrup.
  • Fiber Content: Look for oats that are high in fiber, as they can help keep you full and aid in digestion.
  • Recipe: If you’re following a recipe, choose the oats as directed because using different oats will yield altered results.
  • Gluten Free Option: If you have gluten intolerance or sensitivity, select certified gluten-free oats.
  • Organic: Organic oats are grown without synthetic pesticides or fertilizers. If this is important to you, opt for organic oatmeal.
  • Packaging: Oatmeal can come in various packaging, including bulk bins, canisters, or individual packets. Choose the one that suits your convenience and storage preferences.
  • Instant vs. Traditional Cooking: Consider how much time you have for breakfast preparation. Instant oats cook quickly, while steel-cut oats take longer. Choose accordingly.
  • Taste Test: If you’re uncertain about which type or brand of oatmeal you prefer, try different options to see which one suits your taste best.

It’s essential to choose an oatmeal you enjoy eating that fits your preferences and health goals. 

Add Ins

What is added to oatmeal is arguably more important than oatmeal itself.

Fruits and nuts can boost your oatmeal and make it a more nutrient powerful option. On the other hand, white sugar and butter is turning your oatmeal into a more unhealthy option.

Healthy Add Ins

  • Berries
  • Nuts
  • Seeds
  • Dark Chocolate (70% cacao content)

Unhealthy Add Ins

  • Butter
  • Salt
  • Sugar
