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.
Restless Legs Syndrome Linked To Earlier Death Risk In Men
A new study from the US finds that men with restless legs syndrome (RLS) may have a 39% increased risk of dying earlier compared to men without the condition, which is characterized by an irresistible urge to move the legs when lying down, accompanied by creeping, pulling and burning sensations that usually feel worse at night.
Xiang Gao of Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts, and colleagues, write about their findings in the 12 June online issue of Neurology.
In a statement Gao says their study "highlights the importance of recognizing this common but underdiagnosed disease", which affects 5 to 10% of adults around the US.
Restless Legs Syndrome
Exactly what causes restless legs syndrome is somewhat of a mystery. As it seems to run in families, there could be a genetic factor, according to the National Institute of Neurological Disorders and Stroke (NINDS).
For example, in 2007, two independent groups of scientists discovered genes linked to restless legs syndrome. One of the groups also found a link between iron deficiency and one of the genes.
In a more recent study, researchers investigating the biology behind restless leg syndrome identified factors behind disrupted sleep, cardiovascular dysfunction and pain in the protein profile of people with the condition.
The syndrome has also been linked to kidney disease, the nerve disorder peripheral neuropathy, and other medical conditions. Alcohol and sleep deprivation may worsen or trigger symptoms in some people, and the condition can also occur with certain drugs and during pregnancy.
There is no specific test for restless legs syndrome. To diagnose it, doctors use a checklist of criteria, such as: is there an overwhelming urge to move the affected limb(s), do symptoms get worse at night, are they triggered by rest or sleep, do they go away with movement?
Prospective Study Followed Nearly 18,500 Men for 8 Years Gao and colleagues followed 18,425 men of average age 67 who were free of diabetes, arthritis or kidney failure when they were evaluated for restless leg syndrome at the start of the study period.
