Can certain foods increase your risk for advanced prostate cancer?

 

Avoid these foods if you have a prostate. It’s a good idea even if you don’t have a prostate.

Can certain foods increase your risk for advanced prostate cancer?

According to this research, it can. The researchers examined total, unprocessed, and processed red meat, poultry, and eggs in relation to the risk of lethal prostate cancer (Richman EL, et al., 2011).

 

 

They started following 27,607 men without cancer from 1994 to 2008 who developed distant organ metastases (it spread to other parts of the body), and men who died from prostate cancer during the follow-up. This is what the researchers found.

Men who consumed 2.5 or more eggs per week had an 81% increased risk of lethal prostate cancer compared with men who consumed less than 0.5 an egg per week.

 

 

It was also found suggestive, but not statistically significant, positive associations between poultry 3.5 servings or more compared to 1.5 servings or less per week, and processed red meat 3 or more servings a week compared to 0.5 serving or less per week. The following study is also interesting.

The researchers examined whether dietary choline or choline-containing compounds increased the risk of lethal prostate cancer (Richman EL, et.al., 2012). These men were followed for 22 years.

 

 

47,896 men were included in the study, and they found that the highest quintile choline intake was associated with an increased risk of lethal prostate cancer.

Where do we find high amounts of choline? You may have guessed it, especially in eggs.

We do need choline since the body doesn’t produce enough, but we can get adequate amounts from plant-based food.

Prostate cancer: The most important foods to avoid.

As men get older prostate cancer gets more and more common.

Here are some interesting facts.

After reviewing 13 independent studies, the researchers concluded that the consumption of milk and dairy products increases the risk of prostate cancer (Qin LQ, et al. 2007). Milk stimulated the growth of prostate cancer cells in cell cultures in 14 separate experiments (Tate PL, et al. 2011).

Why would dairy products stimulate prostate cancer?

The kinase mTORC1 which is a regulator of tissue growth and also regulates cell death is stimulated by dairy, and it is upregulated in nearly 100% of advanced prostate cancers (Melnik BC, et al. 2012). It is also another reason and that is hormones which naturally is found in milk.

A study including 47,896 men, the ones with the highest intake of choline, had a 70% increased risk of lethal prostate cancer (Richman EL, et al. 2012).

Where do we find choline?

The foods containing the highest amount of choline are meat, milk and eggs.

Can exercise on it’s own affect prostate cancer?

Posted by on 11:27 pm Cancer, Prostate cancer | 0 comments


We know that exercise, incorporated with a plant based diet and stress management, has a beneficial effect on prostate cancer, but what about exercise on it’s own?

This has now been researched and here are the results.

Patients with recurrence following radical prostatectomy, or patients managed on active surveillance, were either put in a group doing home-based endurance training 3 times per week for 24 months, or a control group receiving usual care (Hvid T, et al. 2015). The participants in the exercise group showed significant improvements in triglycerides, adiponectin, IGF-1, IGFBP-1 and fasting glucose levels.

Adiponectin is a hormone involved in glucose regulation and fatty acid oxidation. IGF-1 is a growth factor and IGFBP-1 stands for IGF-1 binding protein which alters IGF-1 interaction with cell receptors. What is especially interesting is that PSADT (PSA doubling time) increased from 28 to 76 months during the first 6 months of exercise.

PSADT is a calculated number, and a higher value is associated with a reduced risk of disease progression.

None of these changes were taking place in the control group.

This is good news.

Exercise by itself makes a difference, but the smart thing to do is to also incorporate an effective dietary regime as well as stress reduction.

Can you reverse the progression of prostate cancer with lifestyle changes?

Posted by on 10:55 pm Cancer, Prostate cancer | 0 comments

Yes you can, research has shown that it is possible.

The participants in this study were men who had chosen not to undergo any conventional treatment (Ornish D, et al. 2005). These men had a PSA of 4-10 ng/ml and cancer Gleason scores of less than 7.

One group was asked to eat a vegan diet, participate in a stress reduction program, and do light exercises. The control group underwent the usual care. The study lasted for 1 year.

The PSA decreased 4% in the experimental group while it increased 6% in the control group.

6 patients in the control group underwent conventional treatment due to increased PSA and/or a progression of disease as shown on MRI, but none of the patients in the experimental group did.

Implementation of diet and lifestyle changes makes even more sense as a preventative measure.

Omega 3 fatty acid and prostate cancer

If you have watched the news lately, you have probably heard about a study linking increased risk of prostate cancer with omega 3 fatty acids ( Brasky TM, et al. 2013). The media, looking for big headlines, presented this as a new truth about omega 3 fat. Supposedly, it was now dangerous to eat fish and take fish oil. If you have followed this, you have probably also seen a lot of objections to that conclusion, and authorities in this field have been pointing out flaws in the study.

This study is a good example of bad science. The conclusion that omega 3 fatty acids are causing prostate cancer can not be made. It was not a cause and effect study, showing that if you take omega 3 fatty acids you get prostate cancer.

These researchers did not account for important risk factors for prostate cancer. Without doing that, a lot of things can be found to cause prostate cancer. The study participants who developed prostate cancer could have started to take omega 3 fat after they had already been diagnosed with prostate cancer, yet there was no information related to that possibility.

The study did not consider any of the research showing that omega 3 fatty acids are beneficial if you have prostate cancer. Harvard University researchers have completed research on the effects of omega 3 fatty acids from fish on prostate cancer incidence and mortality which included 20167 men and 382144 person-years of follow ups (Chavarro JE, et al. 2008). They found that omega 3 fatty acids from fish was unrelated to prostate cancer incidence, but may improve prostate cancer survival. A Canadian study found no strong evidence for a protective association of fish consumption with prostate cancer, but it did show a significant 63 percent reduction in prostate cancer specific mortality.

How about women, breast cancer and omega 3 fatty acids?

As an example, one study concluded that DHA, one of the active ingredients in omega 3 fatty acids from fish, may slow the proliferation of tumor cells and minimize their metastatic potential (Blanckaert V,et al. 2010). There are also numerous studies showing benefits for the brain as well as the cardiovascular system. I don’t think all of this research can be wrong, so I prefer to keep taking my omega 3 fish oil.

Deep-fried food and the risk of prostate cancer

The study referred here investigated if deep-fried food may increase the risk of prostate cancer (Stott-Miller M,et.al.,2013).

Other research suggests that high-heat cooking may increase the risk of prostate cancer possibly because of the formation of carcinogens.

The researchers found a positive association with prostate cancer risk for people that ate french fries, fried chicken, fried fish, and donuts one or more times per week. The association was even slightly stronger for more aggressive cancers.

Since it wasn’t clear if it was the high heat cooking or the frying that increased the risk, it’s better to just avoid both.
