Thursday, Feb. 16, 2023 (HealthDay News) — Following a healthy plant-based diet after a prostate cancer diagnosis may help prevent the disease from progressing or recurring, new study finds. Suggested.

Men who ate a diet rich in fruits, vegetables and whole grains had a 52% lower risk of cancer progression and a 53% lower risk of cancer recurrence compared with those with the lowest amount of plants in their diet. was discovered by researchers.

“Progression to progressive disease is one of the most important concerns among prostate cancer patients, their families, caregivers, and physicians,” said the principal investigator. Vivian LiuClinical Research Coordinator, Osher Center for Integrative Health, University of California, San Francisco.

“These findings directly inform clinical care by providing dietary recommendations as guidance for managing health and reducing the incidence of the most common cancers facing American men. It may offer other positive health benefits for preventing other chronic diseases as well.

Fruits and vegetables contain antioxidant and anti-inflammatory components, so a plant-based diet may have these benefits.

The diet also reduces potentially harmful exposure to animal foods, such as hormones and heterocyclic amines produced during high-temperature cooking, especially linked to prostate cancer, Liu said.

A diet high in animal protein can also increase insulin resistance, she noted, and milk and dairy products can increase levels of the growth factor IGF1, which has been linked to prostate cancer risk.

For this study, Liu and her colleagues used data from a study that collected information on more than 2,000 men with prostate cancer.

Over a median of 7 years, the researchers found that men who reported the highest plant-rich diet had a lower risk of both progression and recurrence compared to men who ate the least plant. This association did not change with age, walking speed, or cancer severity.

“A healthy, plant-based diet after diagnosis, including vegetables, fruits, legumes and whole grains, may be associated with a reduced risk of prostate cancer progression and recurrence, and a reduction in diabetes.” It adds to the list of many other health benefits, including cardiovascular disease and overall mortality.

The findings will be presented Thursday at the 2023 American Society of Clinical Oncology (ASCO) Genitourinary Cancer Symposium in San Francisco. Findings presented at medical conferences are considered preliminary until publication in a peer-reviewed journal.

Dr. Anthony D’AmicoThe results are encouraging, but they cannot prove that a plant-based diet improves prostate cancer outcomes, said Dr. Dana, director of the Genitourinary Radiation Oncology Division at the Dana-Farber Cancer Institute in Boston. warned. Association between the two.

That said, he added that there is biological evidence that plant-based diets are healthier and can boost the immune system.

“So there is a biological basis that the risk of cancer progression can be delayed as a result of immune surveillance,” D’Amico said. “Conversely, people who follow a plant-based diet are also more likely to exercise, which has been shown to boost their immune system.”

A healthy lifestyle also lowers the risk of cancer recurrence and progression. This is because patients are better able to tolerate treatment, are more likely to receive full treatment, and are more likely to adhere, said D’Amico.

“I don’t want to completely dispute these findings. I don’t want to poop. That’s not a bad thing. I just don’t want people to think it’s proof,” D’Amico said. “I encourage you to consider the big picture: exercise, don’t smoke, don’t drink, eat healthy, reduce stress, all of this helps.”
