Is it possible to prevent Cancer by having a healthier diet?
Prostate cancer patients who replace animal fats and some carbohydrates with vegetable fats have a lower risk of premature death, researchers from the University of California reported in JAMA Internal Medicine.
In the United States alone, nearly 2.5 million men currently live with prostate cancer. Not much is known about how diet may influence prostate cancer progression and death rates, the authors wrote as background information.
Erin L. Richman, Sc.D., and team carried out a study involving 4,577 men from the Health Professional Follow-up Study with non-metastatic prostate cancer between 1986 and 2010. They focused on the patients' dietary fat intake after diagnosis. Every four years, they completed questionnaires which asked how often they ate and drank over 130 different types of foods and drinks. Higher vegetable fat intake reduced prostate cancer death rates and deaths from any cause Over a follow-up period of 8.4 years, 315 men died from prostate cancer and 1,064 died from any cause. Those who replaced 10% of their dietary calorific intake of carbohydrates with vegetable fat had a 29% lower risk of lethal prostate cancer and a 26% lower risk of death from any cause.
The authors wrote:
"In this prospective analysis, vegetable fat intake after diagnosis was associated with a lower risk of lethal prostate cancer and all-cause mortality."
The results of this study go against what many doctors advise their recently diagnosed prostate cancer patients to do, which is "Cut out all fats from your diet". The right advice appears to be to tell the patient to consume more fat, fewer carbohydrates, and to make sure the fats come from plants and not animals.
The authors concluded:
"Overall, our findings support counseling men with prostate cancer to follow a heart-healthy diet in which carbohydrate calories are replaced with unsaturated oils and nuts to reduce the risk of all-cause mortality. ... The potential benefit of vegetable fat consumption for prostate cancer-specific outcomes merits further research."
Commentary: Dietary Fat Reduced Prostate Cancer Mortality Dr. Stephen J. Freedland, from Duke University Medical Center, Durham, North Carolina wrote in an invited Commentary:
"Using data from food frequency questionnaires completed every four years during follow-up, they found that men who consumed more vegetable fat had a lower risk of prostate cancer death.
Thus, in the absence of randomized trial data, it is impossible to use these data as 'proof' that vegetable intake lowers prostate cancer risk, and the authors have carefully avoided such statements.
Dr. Freedland says that the only modifiable risk factor associated with prostate cancer death risk is obesity. In other words, if you are diagnosed with prostate cancer, make sure you don't become obese, and if you are, lose weight.
