It’s hard to believe, but the American Cancer Society (ACS) estimates that about one in eight American men suffers from prostate cancer. In addition to skin cancer, prostate cancer is the most common cancer diagnosed in the United States and the second leading cause of death from cancer among American men.
In 2022 alone, ACS predicts 268,490 new diagnoses and 34,500 new deaths from prostate cancer.
Unfortunately, modern medicine does not know exactly what causes prostate cancer. Like other diseases, prostate cancer is caused by changes and mutations in DNA at the cellular level. Some of these gene mutations are inherited, but most are not. In fact, ACS suggests that most of the gene mutations associated with prostate cancer observed in men are not inherited, but were acquired at some point in the patients ’lives.
So, what are some of the identified external risk factors that can lead to prostate cancer in men? To get started, take action. About 60% of all prostate cancers occur in men over 65 years of age.
Another potential risk factor is obesity. Some studies have found that abdominal obesity is associated with a more aggressive form of prostate cancer. An unexpected factor may be widowhood. One study found that even widowed men were more likely to develop advanced prostate cancer.
A new study has now been published at Loma Linda University and published in the journal American Journal of Clinical Nutrition has identified a new major dietary risk factor for prostate cancer. Read on to learn more!
Too much milk can lead to prostate disease
There are many things you like about milk. It is full of essential vitamins and minerals, is excellent for bone health and contains a powerful protein for loading. The results of this new study, however, show this Drinking milk is associated with a greater risk of prostate cancer.
The authors of the study reported that men who consumed more regular milk were at increased risk of prostate cancer compared to other men who drank less milk. Specifically, the study found that men who drank 430 grams of dairy products (1.75 cups) per day showed a 25% higher risk of prostate cancer than other men who drank less milk daily (half a glass per week). Among those who drank milk daily, the risk of prostate cancer was higher than among men who did not drink milk at all.
Calcium has previously been linked to prostate cancer, and dairy products such as milk contain tons of calcium. Most importantly, the study found no correlation between the risk of prostate cancer and the intake of calcium other than milk. In other words, although it is clear that something in milk is related to the development of prostate cancer, it is not just calcium.
“Our findings add significant weight to other evidence linking dairy products other than calcium to milk as a variable risk factor for prostate cancer,” he says. Gary Fraser, MBChB, PhDchief researcher of the study and professor of the School of Medicine and School of Public Health at Loma Linda University, in a press release.
Interestingly, there was no link between the risk of prostate cancer and the consumption of cheese and yogurt.
Drinking 150 grams of milk a day increases the risk of prostate cancer
The authors of the study note that their work did not find that the risk of prostate cancer increases indefinitely with more milk. The risk increases to flatten two-thirds of a cup of milk every day.
“Most of the continued increase in risk is about two-thirds of a cup of milk a day when you reach 150 grams,” he said. Fraser explains. “It’s like any biological or biochemical way is saturated with two-thirds of a cup of milk per day.”
Solving the secret of milk
As mentioned above, this study proves that calcium alone is not responsible for the connection between prostate cancer and milk. So what’s going on here?
“One interpretation is that dairy products, or some closely related unknown risk factor, are associated with an increased risk of prostate cancer,” the study said.
Dr. Fraser theorizes that sex hormones found in breast milk may be involved. Most (up to 75%) of lactating cows are pregnant, and prostate cancer is simply hormone-responsive cancer. In addition, previous studies have shown that ingestion of milk and other animal proteins is associated with high levels of a specific hormone (IGF-1) in the blood, and that IGF-1 supports the growth of certain cancers, including prostate cancer.
Milk is also linked to breast cancer
This work is well combined with previous research conducted at LLU. This project found that ingestion of breast milk was associated with an increased risk of breast cancer in women.
“The similarities between the paper on women’s breast cancer a year ago and the paper on men are striking,” she said. Fraser’s comments. “It looks like the same biological mechanisms are working.”
In conclusion, the study’s authors do not confirm that breast milk causes prostate cancer, but warn that there is a link between milk intake and the risk of prostate cancer. Finally, more research is needed before any final conclusions can be agreed.
Researchers say that men with prostate cancer may still think twice about using moderate amounts of breast milk.
“If you think you have a higher than average risk, consider alternatives to soy, oats, cashews, and other non-dairy foods,” says the doctor. Sentence conclusions.
These findings are not based on a small-scale research project. The study involved more than 28,000 men in North America, and it took an average of less than eight years.
All participants were cancer-free at the beginning of the study, but their individual dairy / calcium intake habits were very different. Some men drank a ton of milk, while others refused milk altogether. Each person’s normal dairy products were assessed using food frequency questionnaires (FFQ) and a 24-hour diet. The baseline survey, completed by each subject, also collected demographic information such as BMI, exercise habits, smoking habits, family history of cancer, and pre-prostate cancer screening.
After gathering all the initial data, the researchers looked at the state cancer registry for the next eight years. By the end of the follow-up period, a total of 1,254 prostate cancers had been diagnosed.
The research team found that non-dairy calcium intake (nuts, fruits, seeds, vegetables, greens, etc.) was followed by the statistical model regardless of other factors (non-dairy calcium, family medical history, age, etc.).
Overall, the study authors say that the approach they used and the large sample of people who had to work with them made them unique for their research on this topic.
“Because our study cohort showed large differences and differences in dairy products and calcium levels, we were able to ask the question with extraordinary force,” the doctor said. Fraser adds.
