Higher Levels of Melatonin May Reduce Risks of Prostate Cancer

 Prostate Health  Comments Off on Higher Levels of Melatonin May Reduce Risks of Prostate Cancer

Being reported in LiveScience is that “Men with higher levels of the sleep hormone melatonin may be less likely to develop prostate cancer.” This new study also indicates that men with higher levels of melatonin in their urine have a 75% decreased risk of developing advanced prostate cancer.

The researchers do not know if the higher levels of melatonin are naturally occurring or from supplements.

Men who had the lower levels of melatonin were those who took medication for sleep problems, and difficulty in falling and staying asleep. The Independent reports that “Sleep loss and other factors can influence the amount of melatonin secretion or block it altogether, and health problems associated with low melatonin, disrupted sleep, and/or disruption of the circadian rhythm are broad, including a potential risk factor for cancer.”

The researchers stress that this is a small study, and needs verification through replication.

Past studies have also hinted at an increased risk of breast cancer associated with night shift work. As reported by the Journal of the National Cancer Institute, “An increased risk of breast cancer was found among subjects who reported not sleeping during the period of the night when nocturnal melatonin levels are typically at their highest.”

Our body produces melatonin in the dark at night. This hormone regulates our sleep-wake cycle, and influences our circadian rhythm. People with low levels of melatonin typically experience disrupted sleep.

Our bodies typically produce melatonin at levels near 0.3 mg per day. So, you don’t need mega doses of this hormone as a supplement to maintain normal body levels. And according to the University of Maryland, “1 to 3 mg 1 hour before bedtime is usually effective (for insomnia), although doses as low as 0.1 -0.3 mg may improve sleep for some people.” As with all supplements, discuss it with your doctor before taking it.

The medical community is becoming increasingly aware of the role melatonin may play in preventing some cancers like breast and prostate cancers. Poor night sleep and low melatonin levels are associated with increased risk of both cancers. If you decide to take melatonin as a supplement, remember that only small doses are needed. Of course, always talk to your doctor first before taking any supplement.

How To Reduce Your Risk of Prostate Cancer

Stop eating deep-fried foods!

Results of new research from the Fred Hutchinson Cancer Research Center indicate that eating deep-fried food is associated with an increase risk of developing prostate cancer. And frequent consumption of deep-fried foods makes you more likely to develop the aggressive form of prostate cancer.

More specifically, men who report eating French fries, fried chicken, fried fish and/or doughnuts at least twice per week were more likely to develop prostate cancer than men who ate these foods less than once each month. In other words, regular consumption of these deep-fried foods led to a 30 to 37 percent increase risks of developing the disease.

Previous studies have shown that high-heat cooking methods, like grilling meats, has an increase risk of prostate cancer. This is the first study to indicate that deep-frying also has an increase risk.

These studies seem to be indicating that exposing oils and fats to high temperatures creates carcinogenic compounds that lead to cancer. These deadly compounds include

  • Acrylamide which is found in carbohydrate-rich foods like French fries
  • Heterocyclic amines and polycyclic hydrocarbons which are formed when meats are cooked at high temperatures
  • Aldehyde – found in cooking oils exposed to repeated high temperatures
  • And Acrolein – found in fried foods, cooking oils and roasted coffee

High temperature prepared foods also contain high concentrations of advanced glycation end products (AGE’s). AGE’s are associated with increased inflammation, which can lead to cancers, diabetes and heart disease. High cooking temperatures, like when deep-frying, and long cooking times increase the level of AGE’s in food.

This is just one more study that suggest we stay away from foods that are deep-fried or exposed to high temperatures for long periods of time. If you are willing to stay away from deep-fried foods and foods prepared with high heat over a long period of time, you can significantly reduce your risk of developing prostate cancer.
