Higher Consumption of Fruits, Vegetables May Lower Death Risk in Dialysis Patients

However, "future studies exploring the potential benefits of a whole dietary approach in the hemodialysis setting are also warranted and we aim to pursue them", noted lead researcher Giovanni Strippoli, Professor from the varsity

A higher consumption of fruits and vegetables may be associated with a lower risk of premature death in patients undergoing hemodialysis, finds a new study.

Kidney failure patients on hemodialysis are often discouraged from this type of diet due to its potential to cause a build-up of potassium.

The study showed that although a higher fruit and vegetable intake is linked with lower cardiovascular and all-cause mortality in the general population, its higher consumption is associated with lower all-cause and non-cardiovascular death in the hemodialysis population as well.

For the study, the researchers recruited 8,078 hemodialysis patients.

The findings, published in the Clinical Journal of the American Society of Nephrology (CJASN), showed that patients who had less than 10 servings of combined fruits and vegetables per week, had 10 per cent lower risks of death from any cause and 12 per cent lower risks of deaths from non-cardiovascular causes.

In addition, those who had more more than 10 servings had a 20 per cent lower risks of death from any cause and 23 per cent lower risks of deaths from non-cardiovascular causes.

“These findings suggest that well-meaning guidance to limit fruit and vegetable intake to prevent higher dietary potassium load may deprive hemodialysis patients of the potential benefits of these foods. However, intervention trials of fruit and vegetable intake are needed to support dietary recommendations for hemodialysis patients,” said Associate Professor Germaine Wong from the University of Sydney.

However, “future studies exploring the potential benefits of a whole dietary approach in the hemodialysis setting are also warranted and we aim to pursue them”, noted lead researcher Giovanni Strippoli, Professor from the varsity. (IANS)

More Vegetable Consumption May Not Cure Prostate Cancer: Study

Although the MEAL study revealed no positive impact on prostate cancer, it did demonstrate that behavioural modification can lead patients to make healthier food choices

Patients with prostate cancer assigned to eat seven or more servings of vegetables and fruits daily saw no extra protection from the increased consumption of micronutrients, researchers have found.

Previous studies suggest that foods with high carotenoids have antioxidant properties, which can protect men from prostate cancer. Some of those foods include leafy greens, broccoli, cabbage, carrots and tomatoes. However, the study, published in the Journal of the American Medical Association, shows that eating more produce won’t cure, nor stop the disease.

“These data indicate that despite prevailing scientific and public opinion, eating more vegetables will not alter the course of prostate cancer. It will not, to the best of our knowledge, suppress or cure it,” said study researcher J. Kellogg Parsons from University of California.

“However, while eating a healthy diet rich in fruits and vegetables and getting more exercise may not cure cancer, it may keep the body stronger and healthier, which may help patients tolerate cancer treatments,” Parsons added.

For The Men’s Eating and Living (MEAL) study, researchers enrolled 478 men aged 50 to 80 years at 91 sites in the US. The patients had been diagnosed with early-stage prostate adenocarcinoma and enrolled in an active surveillance programme in which patients defer immediate treatment until the disease advances.

Patients were randomised to a control group that received written information about diet and prostate cancer or to a telephone counselling behavioural intervention programme that encouraged participants to eat foods high in carotenoids, such as leafy greens, carrots and tomatoes, and cruciferous vegetables such as broccoli and cabbage.

Both groups were monitored for two years. Patients assigned to the intervention increased their intake of fruits and vegetables to a statistically significant degree, and significantly more than what control patients did. These findings were supported by significant changes in the blood carotenoid levels of the patients.

“Nonetheless, these data fail to support prevailing assertions in clinical guidelines and the popular media that diets high in micronutrient-rich vegetables improve cancer-specific outcomes among prostate cancer survivors,” said study researcher James Marshall.

According to the researchers, scientific studies have identified a strong role for changing diet to improve outcomes in diabetes and cardiovascular disease, but not in cancer.
