Diet rich in fruit, vegetables and nuts can HALVE odds of prostate cancer spreading, finds study

A diet rich in fruit, vegetables, nuts and whole grains may reduce the chances of prostate cancer spreading by almost half, research suggests.

Men who ate the most plant-based foods were less likely see their cancer grow, spread to the bones or ultimately die from it than those who ate the least.

Scientists believe this could be down to reasons including the high levels of antioxidants and anti-inflammatory compounds in fruit and veg, which have been shown to protect against the disease.

The findings indicate simple lifestyle changes can help many men living with lower-level disease to live a full life.

The research involved more than 2,000 men in the US diagnosed with localised prostate cancer between 1999 to 2018 which had not spread.

They were quizzed about their diet and lifestyle and followed for an average of 6.5 years.

Those with the most plant-based diets typically ate 1.9 portions more portions of veg, 1.6 additional servings of fruit and 0.9 more servings of whole grains a day than those who ate the least.

They also ate on average one less serving of dairy — such as cheese — 0.4 less servings of animal fat, slightly less egg and marginally less meat.

Researchers from the University of California, San Francisco, prostate cancer progression including recurrence, secondary treatment — were 47 per cent lower in those who ate the highest plant-based diet levels.

'These findings suggest that consuming a primarily plant-based diet may be associated with better prostate cancer-specific health outcomes among men with prostate cancer,' they wrote in the JAMA journal.

'Slightly reducing intake of animal products and placing more emphasis on more nutrient-dense plant-based foods may be advantageous.'

It builds on previous research which showed the Mediterranean diet — which also includes oily fish — was linked to slower tumour progression among men with localised prostate cancer.

More than 52,000 men are diagnosed with prostate cancer every year on average in the UK, making it the most common cancer in men. Around 12,000 men die every year from the disease - the equivalent of one every 45 minutes

Eating less meat and dairy has also been associated with a reduction in the common side effects seen in prostate cancer patients, including erectile dysfunction and loss of bladder control.

It comes the day after experts declared the UK was at the start of a 'prostate cancer revolution' with a trial which is hoped will lead to a national screening programme.

In a major victory for the Daily Mail's End the Needless Prostate Deaths campaign, the TRANSFORM trial will enroll around 300,000 men to find how best to catch it early and differentiate aggressive from low-risk cancers.

Scientists are confident this will double the number of men that could be saved by screening, reducing deaths by around 40 per cent and green-lighting a national screening programme.

Dr Matthew Hobbs, director of research at Prostate Cancer UK, said: 'This could save thousands of men's lives every year in the UK alone. 

'But it won't just be the UK – this trial could change practice globally.'

WHAT IS PROSTATE CANCER?

How many people does it kill? 

More than 11,800 men a year - or one every 45 minutes - are killed by the disease in Britain, compared with about 11,400 women dying of breast cancer.

It means prostate cancer is behind only lung and bowel in terms of how many people it kills in Britain. 

In the US, the disease kills 26,000 men each year.

Despite this, it receives less than half the research funding of breast cancer and treatments for the disease are trailing at least a decade behind.

How many men are diagnosed annually?

Every year, upwards of 52,300 men are diagnosed with prostate cancer in the UK - more than 140 every day.   

How quickly does it develop? 

Prostate cancer usually develops slowly, so there may be no signs someone has it for many years, according to the NHS

If the cancer is at an early stage and not causing symptoms, a policy of 'watchful waiting' or 'active surveillance' may be adopted. 

Some patients can be cured if the disease is treated in the early stages.

But if it is diagnosed at a later stage, when it has spread, then it becomes terminal and treatment revolves around relieving symptoms.

Thousands of men are put off seeking a diagnosis because of the known side effects from treatment, including erectile dysfunction.

Tests and treatment

Tests for prostate cancer are haphazard, with accurate tools only just beginning to emerge. 

There is no national prostate screening programme as for years the tests have been too inaccurate.

Doctors struggle to distinguish between aggressive and less serious tumours, making it hard to decide on treatment.

Men over 50 are eligible for a ‘PSA’ blood test which gives doctors a rough idea of whether a patient is at risk.

But it is unreliable. Patients who get a positive result are usually given a biopsy which is also not fool-proof. 

Scientists are unsure as to what causes prostate cancer, but age, obesity and a lack of exercise are known risks.
