Invite Health Podcast, Episode hosted by Jerry Hickey. Ph
In the 1970's when I started studying Pharmacy and the 1980's when I started studying nutrition, scientists at leading academic research institutions were already trying to sort out what increases the risk for common cancers and what decreases the risk. And we've come a long way with that research; you can definitely point at lifestyle habits and nutrients that reduce your risk for prostate, breast, colon or pancreatic cancer and others that increase your risk. Now, prevention is different than treatment.
It's interesting to mention that may of the things that reduce the risk of prostate cancer, also improve the treatment. You will see this frequently in research. On today's episode we will discuss things that men do every day that can increase their risk of developing prostate cancer and the lifestyle habits, foods and nutrients that may help to reduce that risk. Each part of this discussion is based on the results of multiple human studies
Being Overweight or Obese
One of the risks for many cancers is being overweight, especially being obese. About 40% of Americans can be categorized as obese. In other words, they have an awful lot of fat. So many American adults are overweight, but a serious number of people are obese. Being obese is extremely dangerous; this increases your risk of sleep apnea, atrial fibrillation, snoring, back aches, knee pain, arthritis, and of course cancer.
An American Cancer Society Study showed that, for men who were overweight (not obese), the extra risk of developing prostate cancer was 8%. Now, that may not sound huge to you but prostate cancer and being overweight is so common, that this percentage does translate into quite a few men developing cancer. Now, obese men had a 20% increased risk of developing prostate cancer, according to the study. Being severely obese showed a 34% increased risk of developing prostate cancer.
According to a study published in the Journal of Clinical Oncology
by The American Cancer Society in Atlanta, researchers wanted to know what happens to men who are overweight if they develop prostate cancer. This study highlights that there are connections between prevention and treatment. After diagnosis of prostate cancer in obese men, results showed that there was a prostate cancer specific mortality trend. In other words, these men were more likely to die from the cancer and have advanced stages of it. But they also had a much higher risk of dying from heart disease and all-cause mortality.
It is important to understand that excess weight not only increase the risk of prostate cancer, but it also makes it more dangerous. Part of the reason why this happens is that there is fatty tissue lining the prostate. This fatty tissue can contribute to the prognosis of prostate cancer. Science has found that, in obese men, this fatty tissue releases cytokines. These are chemical messengers that inflame the cancer and make it grow and spread more easily.
Diet and Prostate Health
The Journal of Human Nutrition and Dietetics
published a systematic review on what increases the risk of prostate cancer and what reduces it. In this review, researchers noted that red meat
slightly increased the risk and found that processed meats
was even more dangerous. Processed meats include hot dogs, spam, salami, bologna, bacon and sausage. Also to note when it comes to meat consumption, it seems to be worse if the meat is barbecued, smoked, fried or grilled.
is what makes tomato sauce red. When you cook down tomatoes, you are releasing this red-pigment called Lycopene. So whenever you use Lycopene as a supplement, you want those tomato ollio resins in it and you want it to be natural Lycopene. A systematic review has found, if you have tomato sauce - or Lycopene (5mg or more, 2x a week or more) - it may help reduce your risk of developing prostate cancer. Also found, the amount of Lycopene in your blood is connected to a reduced risk of prostate cancer, an advanced prostate cancer or progression of prostate cancer in three recent-case controlled studies. In other words for men who had prostate cancer, if they had higher levels of lycopene in their blood, it was less likely to become dangerous or advance. A meta-analysis of other case-controlled studies (21 studies) and 10 cohort studies found an association between Lycopene and a decreased risk of prostate cancer. The research concluded that, "Lycopene - even when looking at Lyopene in the blood - was associated with a lower risk."†
A very large perspective cohort study in Japan found that Green Tea
reduced the risk of prostate cancer, and it was dose-dependent. This simply means that the study found that the more Green tea, the better. Now, you should never have eight-ten green tea cups per day. But these researchers found that five cups per day was beneficial for reducing the risk of prostate cancer. Separately, in the journal Medicine
, a systematic review and meta-analysis of ten studies studied Green tea and prostate cancer risk. This research found that more cups of Green tea daily reduced the risk; they found that seven cups per day reduced the relative risk by 62%, and it was a linear trend. In the archives of the Italian Journal of Urology and Andrology from Gint University and the University of Insubula in Italy, performed a meta-analysis of four human clinical trials where they studied men with an increased risk of prostate cancer, or high-grade PIN. Not every man has the same risk of developing prostate cancer. Some men have a condition called high-grade PIN, which stands for prostatic intraepithelial neoplasia (when the cells in your prostate are damaged). And, if this converts to something called ASAP (atypical small acinar proliferation, when some of the cells may actually be prostate cancer), that creates an even bigger risk of prostate cancer. The research found, for the men in the Green tea group, 8% developed prostate cancer. But for the men in the placebo group, 22% of them went on to develop prostate cancer. Researchers noted that, there was a significant - 59% - reduction in the risk of developing prostate cancer. The H. Lee Moffitt Cancer Center (also a research institute) in Tampa, Florida published a study in the journal Cancer Prevention Research
that reports in the incidence of prostate cancer, especially the death rates, is much lower in parts of Asia where they consume a lot of green tea. Researchers go on to say that, "Men who move from countries like Japan and stop drinking green tea, their incidence of prostate cancer increases and it becoming a risk increases to that of men who have grown up in the United States."†
