The unexpected food that puts your prostate at risk

Men with a higher consumption of dairy foods, especially milk, face a significantly increased risk of prostate cancercompared to men with a lower consumption, says Infosalus about the new research.

The study evaluated the dietary intake of more than 28,000 North American men on a diet rich in dairy and calcium. None of the participants had prostate cancer at the start of the study.

The researchers used state cancer registries to track the participants’ prostate cancer status. The follow-up was for almost 8 years.

The study reviewed by Infosalus revealed that:

  • Men who consumed about 430 grams of dairy per day (1 and three-quarters of a cup of milk) had a 25% increased risk of prostate cancercompared to those who only consumed 20.2 grams of dairy per day (half a cup of milk per week).
  • Men who ate about 16 ounces of dairy a day had an even higher increased risk of prostate cancercompared to those who did not consume any dairy in their diet.
  • Increasing dairy intake in 50-gram increments did not produce the same increases in risk as portion sizes became larger.
  • No significant associations were seen with cheese and yogurt.
  • There was minimal variation when whole milk intake was compared to reduced or skim milk intake.

Food: How does milk affect the prostate?

The Infosalus site says that Gary Fraser, principal investigator of the study and professor at the Loma Linda University School of Medicine and School of Public Health explained:

Our results add significant weight to other evidence associating dairy, rather than non-dairy calcium, as a modifiable risk factor for prostate cancer. Our results add significant weight to other evidence associating dairy, rather than non-dairy calcium, as a modifiable risk factor for prostate cancer.

And it is that, the study did not find that relationship between an increased risk of prostate cancer and non-dairy calcium intake.

This suggests that other substances in dairy products, in addition to calcium, could play a role in the increased risk of prostate cancer.

One interpretation of the study results is that “dairy foods, or some unknown closely associated risk factor, are causally related to prostate cancer risk“.

According to Fraser -says Infosalus- One of the possible reasons for these associations between prostate cancer and dairy milk could be the sex hormone content of dairy milk.

The study was published in the ‘American Journal of Clinical Nutrition’.

What food to eat for the prostate?

The principal investigator of the aforementioned study recommends considering other options such as sources of calcium.

“If you think you’re at higher than average risk, consider alternatives to soy, oatmeal, cashews, and other non-dairy milks.”

Non-dairy sources of calcium include nuts, seeds, cruciferous and other green vegetables, legumes, fruits, and fortified cereals.

For its part, the American Cancer Society says:

“It may be advisable to limit the intake of calcium supplements, as well as the amount of calcium-rich foods.”

Although, he clarifies:

“This does not mean that men being treated for prostate cancer should not take calcium supplements if their doctors recommend it.”
