Eating your fruits and vegetables, especially a rainbow assortment of them, is associated with a lower risk of prostate cancer as well speeding up recovery in men who received radiation treatment for prostate cancer.
Two recent studies by the same group of Australian researchers found that certain micronutrients found in foods are lower in men with prostate cancer (compared to healthy men). These are lycopene, selenium, lutein, lycopene, α-carotene, β-carotene. Lycopene and selenium appear to be especially important.
Tomatoes and tomato products (e.g., tomato sauce) are an especially good source of lycopene. Other lycopene rich foods are: watermelons, grapefruits, guava, melons, papayas. Selenium rich foods include Brazil nuts, seafood, organ meats, beef, pork, chicken, turkey, and eggs.
From Medical Xpress: Rainbow of fruit and veg the best prevention against prostate cancer
Men who consume colorful fruits and vegetables on a regular basis are less likely to be diagnosed with prostate cancer (PC), according to new research by University of South Australia scientists.
A rainbow of foods rich in certain micronutrients helps to prevent prostate cancer (PC) as well as speed up recovery among men who undergo radiation treatment for the disease.
The findings, from two studies published in the journal Cancers, highlight the importance of a Mediterranean or Asian diet that includes these foods.
Researchers compared micronutrient plasma concentrations of prostate cancer patients with a healthy control group, revealing low levels of lutein, lycopene, alpha-carotene, and selenium in PC patients and high levels of iron, sulfur, and calcium in the same group, relative to controls.
Increased DNA damage after radiation exposure was also associated with low lycopene and selenium in blood plasma.
Men with plasma concentrations lower than 0.25 micrograms (ug) per milliliter (mL) for lycopene and/or lower than 120ug/L for selenium have an increased risk of prostate cancer and are likely to be more sensitive to the damaging effects of radiation.
Foods that are rich in lycopene include tomatoes, melons, papayas, grapes, peaches, watermelons, and cranberries. Selenium-rich foods include white meat, fish, shellfish, eggs, and nuts.
Study co-author Dr. Permal Deo says eating foods that are naturally rich in lycopene and selenium is preferable to taking supplements, where the benefits are limited, according to previous studies.
