Together we will beat cancer


People reading some of today’s alarming headlines will be relieved to learn that – for the vast majority of people – eating protein isn’t “as bad for you as smoking”.

Tobacco is the single biggest cause of preventable disease and early death in the UK.

It’s difficult to overstate the harm that tobacco causes – half of all long term smokers die as a result of their habit, and half of them in middle age.

If you smoke, even if you are partial to the odd cheeseburger, the best thing you can do for your health and cancer risk is to quit smoking.

Inconclusive study

Today’s media stories were triggered by an interesting but far from conclusive study, published in the scientific journal Cell Metabolism.

The study asked around 6,400 US adults, aged 50 and over, what they’d eaten over a 24 hour period along with some other questions about their lifestyles.

The researchers then ‘followed up’ these people over a period of up to 18 years to see, essentially, which people died and what of.

The most striking finding was that people who were aged 50-65 when the study began and who said they ate a diet with high levels of animal protein – as a proportion of their total calorie intake – were four times more likely to die from cancer than people who said they ate a low-protein diet.

But when the researchers looked at people aged 66 and over, they found the opposite – the people who ate the highest amounts of protein were less likely to have died from cancer during the study than people who ate only a little.

On the face of it, this is quite a strange finding – why would protein be seemingly so bad for you at one point, but then protective a few years later? So it’s worth considering whether factors in the study design, or just pure chance, could help to explain the findings.

There are several reasons why we think caution is required when interpreting the results of this study:

  • 6,400 people may seem like a lot, but by the time the researchers were looking at deaths from cancer the numbers were in the hundreds. We’d really like to see many more people than this to be more confident in the results.
  • The conclusions are based on a single survey of what people reported eating in the preceding 24 hours. It’s a big leap to presume that people’s diets didn’t change in the following 18 years.
  • It’s not clear how accurately the researchers adjusted for other things such as whether people smoked in the past.
  • Because this research looked at deaths from cancer, not cases of cancer, we can’t know whether protein was linked with people’s chance of surviving cancer, developing the disease in the first place, or both.
  • The study didn’t compare the risks of smokers versus people who ate lots of animal protein, so it’s not accurate to say that high protein diets are as deadly as smoking.

Does protein still have a place in a healthy diet?

Yes, but it’s not quite that simple.

There’s good evidence linking diets high in red and processed meat – including beef, pork, lamb, and sausages and bacon – with a moderate increased risk of cancer, particularly bowel cancer, as well as heart disease. So if you’re a self-confessed meat fiend – and eat piles of red and processed meat – then we would encourage you to cut down to help reduce your risk of cancer.

Because this study looked at animal protein as a whole, we can’t tell whether the links the researchers saw were driven by red and processed meats, rather than fish, poultry and dairy.

But they did note that vegetable proteins – from things like beans and other pulses – didn’t seem to be associated with an increased risk.

This fits with what we already know about food groups and health – beans and pulses are also usually high in fibre, plus a serving counts as one of your five-a-day. Getting plenty of fibre, fruit and veg – and swapping other protein sources for red and processed meat – are all good ways to make your diet better for you.

Balance and moderation are key

It’s important, so we’ll repeat ourselves – if you want to improve your health and you’re a smoker, quit.

And when it comes to diet, whatever your age, balance is the key to healthiness.

It might be boring, but it’s true. Healthy living is about moderation. If you’ve got a tab at the local kebab house or burger van, then you probably already know you could benefit by cutting down a little. But on the other hand, as New Scientist note, you can has cheezburger every now and then.

Our message on diet remains the same and is backed by decades of evidence – eat plenty of fibre, fruit and vegetables; cut back on red and processed meat, salt, and high calorie foods; and cut back on alcohol.

Making healthy choices like this means giving yourself the best possible chance when it comes to avoiding diseases like cancer, diabetes and heart disease.

I have seen way too many people die while in normal cancer treatment to believe that there is something “better” in these treatment techniques. They are good in prolonging the suffering, but the real cure, as Julie Priestley stated below, is the diet and healthy lifestyle. Although I am not medical professional, I have my doubts about the cancer research, since it was started (and heavily funded ever since) in the 60s or 70s. Where are the real, tangible results – not just statistical manipulation with the data to let it seem like people are getting cured. They are not, especially if they don’t change their habits.

Our only hope is to receive unbiased information (which is almost impossible with too many interests from the companies and hospitals which provide cancer treatment). And to live a healthy life, with a plant based diet.

I do not want to look like I believe the only way how you can get cancer is by eating red meat or eating other animal products. There are obviously many other hazards, as for example asbestos or lead in your old home’s pipes.

The issue here is not JUST about red meat….all animal foods make the body ACIDIC, plant foods make it ALKALINE. The evidence is already out there, an acidic body cannot fight disease, be it cancer, rheumatoid arthritis, or any other auto-immune disease. The body’s defence is it’s immune system…plant foods feed the immune system, animal foods feed disease – the diet should be no more than 20% animal food to 80% plant based food. There is no point throwing endless money into drug companies – research should be directed at diet, lifestyle & the holistic approach. In most instances chemo just obliterates the only defence mechanism the body has….the immune system.. why, after SO many years of research do we have no cure for cancer? Because we already know, that in a nutshell, an acidic body is why we get ill, and the immune system, given the correct nutrition, is the only way to healing. There are numerous books written by professional people that explain this in detail eg: ‘The pH Miracle’ by Dr. Robert Young, ‘Never Fear Cancer’ Again by Raymond Francis Msc, ‘The Rave Diet’ by Mike Anderson – all hugely enlightening. This is not quackery.
As a former trained nurse, I have seen the amount of people with cancer soar, but still after year upon year of research, still no ‘cure’. My sister recently died of pancreatic cancer, which is why I did extensive research of my own, on top of my nutrition knowledge, to try and determine why. She said herself that her diet was bad, loads of meat & animal products, not much veg, no fruit. An operation & chemo were devastating to her. The sooner the powers that be wake up to the fact the present ‘treatments’ don’t work, despite bamboozling us with figures to suggest they do, the better!!

No there is NOT good evidence linking red meat and cancer, The EPIC study gave a risk ratio of 1.02 for red meat. It merely sews confusion to keep on propagating this myth. See
