Flaxseed – The Basics

You’ve probably heard that flaxseed is deemed the most potent plant-based food on the planet. And for a good reason.

The worldwide flaxseeds market is estimated to be worth over $423 million, with a possible growth rate of 12.7% by 2025.

That’s a lot for such a simple food. Or is it?

Cohort studies indicate that the product has numerous beneficial properties. It can decrease the risk of heart problems, diabetes, reduce cholesterol, etc. Due to its high omega 3 fatty acid content, it has some remarkable uses.

Since it is packed with nutrients, it can aid digestion and provide the body with a good healthy boost.

Because of that, it is also used in supplements.

The main reason people purchase a product like this is to give the body a natural boost.

What’s the Connection With Prostate Carcinoma?

The use of the food dates back to ancient China and Egypt, which has made it one of the oldest fiber crops to be cultivated.

The seeds are packed with vitamin B1, manganese, and other nutrients. Even though research is limited, flaxseed might have the potential to protect the body from conditions such as prostate cancer and metabolic illnesses. 

Beneficial Properties for Carcinoma of the Prostate

Everyone knows that physical activity and a nutritional dietary pattern are great for prostate health.

A diet packed with vitamin E, minerals, and nutrients can decrease overall cancer risk. 

While being overweight drastically amplifies the risk of advanced prostate cancer or aggressive prostate cancer that could potentially spread. The high fatty acid and fiber content makes flaxseeds excellent for the body.

Data indicates that severely obese men are at great risk for prostate carcinoma death. They have a 34% bigger risk as opposed to healthy-weight patients.

A healthy diet and lifestyle are here to manage the side effects of prostate cancer treatment and boost overall health.

As a natural antioxidant with profound nutritional contents, flaxseeds could help with:

  • Constipation
  • Cardiovascular health
  • Blood sugar control
  • Pre-diabetes prevention
  • Hot flashes management
  • Cholesterol control

According to animal studies, a diet supplemented with 5% flaxseed can inhibit the development and growth of prostate carcinoma.

After 20 weeks of treatment, the experimental group experienced a similar difference to the one seen after 30 weeks of treatment, meaning that flaxseed supplementation was beneficial for prostate cancer.

Other research showed similar results. The study published direct evidence that flaxseed supplementations, particularly consumptions of plant lignans, inhibited cancer cell growth and possibly slightly reduced the tumor in a prostate cancer patient.

Due to their chemoprotective elements, consumables, such as flaxseed, which is packed with enterolignans, need further exploration. More studies can help identify the exact impact of a prostate cancer diet. 

Cautions When Using Flaxseed

Flaxseed in diet can definitely be fit for those who want to work on their prostate or prostate cancer. The impact may vary but can be of use.

While it can’t replace conventional cancer treatment, a diet rich in vitamin E, nutrients, and minerals, could assist the system to some degree with early-stage prostate cancer. 

However, if you don’t watch the intake, or your body is not too fond of flaxseed in your diet, then you can experience some bowel changes. Increased doses are most likely linked to gastrointestinal adverse effects. 

Is There a Right Way to Add Flaxseed to a Diet?

The majority of nutritionists suggest ground flaxseed over whole flaxseed in a diet. This is because the ground form is much easier on the stomach.

When incorporating it into a diet, it is important not to go overboard. That can be achieved with the following tactics. 

These include:

  • Pouring 1 tablespoon of ground flaxseed in a breakfast cereal bowl. 
  • Combining a tablespoon of the product with 8 ounces of yogurt.
  • Smearing a teaspoon of ground flaxseed on a mustard or mayonnaise spread when preparing a sandwich. 

The trick is not to use the product together with oral medications.

If you decide to implement flaxseed in your diet via supplements, then it’s best to consult with a specialist.

They can decide the most viable diet changes that could come in handy for the prostate and overall health. 

Other Diet Perks for Prostate Carcinoma

Many men with localized prostate cancer who are on active surveillance are eager to find a suitable prostate cancer diet.

Even if the body doesn’t have cancer yet could be susceptible to some level of cancer risk, healthy food choices can prove useful. 

Healthy food doesn’t provide a guaranteed cancer prevention tactic. It is here to give the body the boost it requires that might benefit prostate cancer prevention to some extent.

Here are a couple of other diet perks and disadvantages for prostate carcinoma that can help you make that choice. 

To start, it is important to point out the impact of cruciferous vegetables on cancer.

Options like broccoli, cauliflower, and cabbage are rich in beneficial compounds that could lessen cancer risk from prostate cancer.

Mediterranean Diet

The Mediterranean diet is considered to be even more influential for cancer.

Experts have found a solid link between lower risk of cancer grade progression and high baseline diet score. 

Experts found a >10% drop in cancer progression risk for every point added in the Mediterranean diet score.

Western Diet

While the effects of the Western diet are completely the opposite.

After a patient has been diagnosed with prostate cancer, and they’ve opted for processed meat, meals high in animal fat, like red meat, or too much saturated fat, they’ve experienced a drastically elevated risk of both overall mortality and prostate cancer mortality.

Research shows that fermented dairy products could influence prostate cancer via the intestinal microbiome.

Very high milk consumption or other dairy products could boost the proliferation of cancer, which can amplify the possibility of prostate cancer.


Focusing on vitamin E and vitamin D intake is equally impactful.

Vitamin E is said to have a mild protective effect on prostate cancer.

In comparison, vitamin D from supplements and diet depict a correlation with reduced BPH (benign prostatic hypertrophy) prevalence rate.  Vitamin D supplementation could lessen prostate volume in BPH patients.

Plant Based

Although people don’t have to necessarily dedicate their life to a plant-based diet or completely eradicate dairy products from their meal plans because of cancer, they can take things in moderation.

A diet rich in healthy oils, omega 3, fruits, and veggies is a great choice for a fully functioning prostate.

While the Mediterranean diet seems to be the most popular prostate cancer diet for a healthy prostate.

Another thing to have in mind is heterocyclic amines. These chemicals can form in poultry, fish, or meat when the product is cooked at very high temperatures. The risk may be low, but they can cause cancer. 

The goal is simple. Instead of saturated fats, a lot of salt, and sugar, people can choose monounsaturated fats to lessen the possibility of cancer death. These are avocados, olive oil, nuts, etc. Soy foods can be a healthy alternative to meat, at least from time to time. 

After getting a prostate cancer diagnosis, and even before that, people should eat healthily and focus on fresh produce.

Depending on the cancer stage or the possibility for cancer recurrence, patients may be advised to get hormone therapy.

But, only a doctor can suggest the most beneficial treatment after analyzing the state of the prostate cancer cells.  


Flaxseeds and other dietary food choices can create a positive impact on overall health.

However, they are not the first line of treatment for cancer.

They have an added benefit and could prove advantageous when changing your lifestyle or diet. 

Being physically active is highly important. As well as skipping foods that may aggravate cancer.

But, for serious conditions, like cancer, you should always consult with a doctor.

Any drastic changes to your diet can impact your current health condition.
