The 10 Worst Foods For Prostate Health — and What Can Help Written by Dr. Michael Ruscio, DNM, DC on March 2, 2022
How to Change Your Diet and Lifestyle to Boost Your Prostate Health
Eating well and avoiding too many processed foods has many general and more-specific health benefits, one of which may be to help men minimize prostate problems.
In men over 50, prostate conditions are common, causing symptoms such as pain when urinating, and needing to go to the bathroom more often. The most common issues are [1]:
Benign prostate hyperplasia (enlarged but not cancerous prostate)
Prostate cancer
Prostatitis (swelling and inflammation of the prostate gland)
Later in this article we’ll look in a bit more depth at how diet, lifestyle, and supplements can influence prostate health and your risk of developing one of the conditions above. But first, let’s dive right in with the 10 worst foods for prostate health so you know what to minimize or avoid for good prostate health.
10 Worst Foods For Prostate Health
Here, we’ll drill down into the foods and categories of foods that aren’t usually good for prostate health. But you should always bear in mind it’s the totality of the diet that counts, and it’s also possible to over-generalize as to what specific diet habits are good or bad for the individual.
However, science does point to some foods/nutrients that generally aren’t good for prostate health (and don’t tend to be great for overall health either). In no particular order, these include:
1. High-Glycemic Carbs
High-glycemic carbohydrates are sugary foods and refined carbohydrates (e.g. white rice, white flour, and refined cereals) that trigger large and rapid rises in blood sugar. Two meta-analysis reviews from 2015 and 2020 found a link between higher-glycemic carbohydrate intake and higher prostate cancer occurrence [2, 3]. High-glycemic foods can raise insulin levels, which in turn can stimulate the production and secretion of sex steroid hormones that are big contributors to prostate cancer development.
Some evidence, so far only demonstrated in animals but interesting nonetheless, suggests that a high-glycemic diet also changes the gut microbiome [4]. As we’ll see below, microbiome changes may also be linked to prostate problems.
2. Fried Foods
Fried foods like donuts, fried chicken, and fries may be linked with higher prostate cancer risk. Though the results of individual studies vary, a meta-analysis of these studies found that a larger intake of fried food was associated with a 35% increased risk of prostate cancer [5]. Potentially carcinogenic compounds, such as heterocyclic amines and polycyclic aromatic hydrocarbons, can form in oil when it’s heated to high temperatures [6].
3. Inflammatory Diets
A 2020 systematic review and meta-analysis found that overall, inflammatory diets were related to a greater risk of prostate cancer [7]. A similar 2019 review came out with comparable results [8]. Foods that tend to trigger inflammation for everyone include [9]:
Soda and other sugar-sweetened beverages
Refined carbohydrates, such as white bread and pastries
French fries and other fried foods
Excess red meat (burgers, steaks) and especially processed meat consumption (hot dogs, sausage, etc.)
Margarine and shortenings
Beyond these obvious culprits, any food can be inflammatory if you’re currently experiencing an intolerance to it. Experiencing gut sensitivities and microbiome imbalances in conjunction with other inflammatory health problems (including prostate inflammation) might mean you could benefit from an elimination diet to root out what these sensitivities are.
As an example, the Paleo diet removes many common culprit foods, allowing inflammatory symptoms to resolve. You can then experiment with reintroducing (healthy) foods one by one to figure out your individualized tolerance for specific foods (which can vary over time).
4. Dairy
Overall, a diet high in dairy products, milk, low-fat milk, cheese, and total, dietary, and dairy-based calcium may increase the risk of prostate cancer. For example, each 50-gram (2-ounce) cheese serving per day increased prostate cancer risk by 9%. It’s surmised that this might have to do with milk causing an increase in a substance called insulin-like growth factor (IGF) [10]. Eating more high-fat dairy products is also linked with a higher risk of benign prostate disease (BPH) [11].
5. Calcium Supplements
Higher total calcium intake from food and supplements also appears to be a risk factor for prostate cancer, according to two meta-analyses. As such, keeping supplementary calcium intake low or moderate may be wise for reducing the risk of prostate cancer [12, 13].
6. Spicy Foods
In a survey of men with chronic prostatitis, 47% reported that the consumption of spicy foods, hot peppers, and chili aggravated their symptoms. Spicy foods may mildly irritate the bladder and prostate, exacerbating symptoms [14].
7. Alcohol

Alcohol intake over a lifetime may significantly increase the risk of contracting advanced cancer. Men who drank at least seven drinks per week between ages 15 to 49 years had a more than threefold greater likelihood for developing high-grade prostate cancer than men who didn’t drink, according to one study [15].
8. Excess Salt
A high sodium intake can sometimes increase the urinary tract symptoms that are typical of BPH. Following a reduced-sodium diet by avoiding processed foods and not sprinkling the salt shaker over meals may therefore be helpful for some men. That said, sodium is an essential nutrient that helps the body balance its water levels, so extreme sodium restriction isn’t advisable.
9. Excess Saturated Fat
Total fat intake appears not related to prostate cancer risk, and healthy fats such as omega-3 fatty acids seem to be beneficial. However, a high intake of saturated fat or animal fat — the kinds found in full-fat dairy products and fatty meat products — has been associated with a higher risk of advanced prostate cancer [16, 17]. Overall though, saturated fat has been too much maligned and it isn’t the dietary demon that it’s sometimes portrayed as [18]. Consuming some saturated fat is perfectly fine, and in fact essential; it’s just excess that is an issue.
10. Eggs
In one large observational study, men who ate an average of 2.5 or more eggs per week had an 81% higher risk of developing a lethal form of prostate cancer compared to those who ate an average of less than half an egg per week. However, the study also found that men who consumed more eggs also tended to exercise less and have a higher BMI, and were more likely to smoke and have a family history of prostate cancer [19].
Other research suggested that eating five or more eggs per week could slightly increase the risk of dying from prostate cancer, but not developing it [20]. Eggs are nutritious and it’s fine to enjoy them in moderation, but ideally not in excess with prostate health in mind.
Common Prostate-Problem Symptoms
Most of the symptoms related to poor prostate health are urinary symptoms. This is because the prostate sits just under the bladder and surrounds the “exit” part of the urinary tract, known as the urethra (pee tube). When there’s prostate gland enlargement, this can press on and irritate the urethra.
Signs that you have a prostate issue, which may be benign or cancerous, include [1]:
A need to urinate more frequently
Getting up several times during the night to pee
Blood in the urine or semen
Pain or burning during urination or ejaculation
Pain or stiffness in lower back, hips, pelvic or rectal area, or upper thighs
Dribbling of urine
Any of these problems should be checked out by a doctor.
Diagnosing Prostate Problems
To diagnose prostate issues you might be given an internal examination (a gloved, lubricated finger is inserted into the rectum) and a PSA blood test that looks for a specific protein (prostate-specific antigen), which can be elevated in certain prostate conditions [21].
Depending on the results, you may need follow-up tests that help to refine a diagnosis [22].
Foods That Help Prostate Health
While there’s no one diet that can guarantee good prostate health, an anti-inflammatory dietary pattern has shown to be associated with better prostate health, particularly reduced prostate cancer risk [7].
Broadly speaking, an anti-inflammatory diet means an unprocessed diet that encompasses a wide variety of antioxidants from vegetables, berries, nuts, and seeds. Eating quality lean protein, and only modest amounts of higher nutritional-quality carbohydrates (e.g. whole grains, not refined) will also keep your diet in the anti-inflammatory zone.
Being aware of your own food sensitivities and how to identify them (as outlined briefly above) will also help you create an inflammatory diet tailored to your own needs.
Within these generalities, however, there are some more-specific foods and supplements that are recommended to consume for prostate cancer prevention. These include:
Green tea: Seven cups a day gave a good preventive effect against prostate cancer in one meta-analysis, but if that’s too much to stomach, green tea antioxidant supplements also seemed effective [23].

Cruciferous vegetables: Men who ate cruciferous vegetables like Brussels sprouts, cabbage, and broccoli typically had a 10-21% lower risk of prostate cancer in one study [24].

Tomatoes: Higher consumption of the antioxidant lycopene from cooked (not raw) tomatoes and sauces is associated with a reduced risk of prostate cancer. Cooking increases lycopene absorption [25, 26].

Saw palmetto: This herb can help benign prostatic hyperplasia symptoms, improving quality of life. A 2020 systematic review and meta-analysis comparing it with the pharmaceutical treatment tamsulosin, found the herb was as effective as the medication at improving quality of life, urinary flow rate, bladder emptying, and PSA levels. It wasn’t as good at reducing prostate volume, though [29].

However in another study, selenium supplementation in men who already had good selenium levels actually seemed to increase risk for aggressive prostate cancer [17]. The best idea seems to be to get your selenium from dietary sources such as Brazil nuts, whole grains, and tuna fish.
Prostate Health and the Microbiome
Several studies have indicated that an imbalanced gut microbiota can influence the imitation and growth of prostate tumors (and other cancers). It’s likely this is two-way, with the microbiota affecting the progression or response of cancers, and cancer also altering the microbiota’s composition [31].
One theory is that the gut microbiome may have a role in prostate cancer via the metabolism of estrogen, high levels of which have been associated with the development of prostatic cancer cells [32].
Overall, the relationship between the gut microbiome and prostate cancer is little understood, but studies do suggest that people with prostate cancer have a different microbial profile than people who do not.
For example:
Microorganisms associated with a higher risk of developing or having extensive prostate cancer include: Bacteroides, Streptococcus, Bacteroides massiliensis, and Mycoplasma genitalium.
Microorganisms associated with a lower risk of prostate cancer were Faecalibacterium prausnitzii and Eubacterium rectalie [32].
While this doesn’t mean we need to try to micromanage our gut bacteria, it does suggest that overall gut microbiome health is associated with prostate health, underscoring the importance of maintaining a healthy gut.
Evidence also suggests that gut dysbiosis (imbalances in gut bacteria) may be an underlying, primary cause of chronic prostatitis [33].
Rebalancing Gut Microbes
Rebalancing your gut microbiota isn’t one simple process and involves a healthy diet, adequate exercise, and good sleep. You can read more about it in my book, Healthy Gut, Healthy You.
However, taking probiotics is a simple step that can definitely help.
Though there’s no direct evidence that probiotics can reduce prostate cancer risk, we do know that the benefits of probiotics include improving gut dysbiosis and inflammation [34, 35], which might be underlying risk factors.
Probiotics have also shown to be helpful in improving symptoms of prostatitis [36, 37, 38].
