High-protein diet 'as bad as smoking 20-a-day'

We've been hearing today about the worrying statistic that eating a protein-rich diet is almost as bad for you as smoking 20 cigarettes a day, in terms of your risk of developing cancer.

The link between red meat and cancer has long been known about but a recent study has shown that the link may in fact be more widespread amongst protein in general. The University of Southern California found that protein from animals in particular carried higher risks to health, such as red meat and eggs.

The American research which has been published in the journal Cell: Metabolism, looked at thousands of adults for almost 20 years and found that those eating a protein-rich diet are a whopping four times more likely to die of cancer than someone following a low-protein diet. They were also found to be more likely to develop diabetes.

The study defined a high-protein diet as one where 20% of the calories come from protein.

We spoke to Atkins, the popular high-protein diet plan, to get their response on the study. They said, 'The sample used in the research consumed a high percentage of carbohydrates (51%) at the same time as protein, meaning this isn't representative of those who follow Atkins, who are advised to take less than 10% of their calories from carbohydrates.' 

Dr Eileen Crimmins, who co-authored the study, said, 'The research shows
that a low-protein diet in middle age is useful for preventing cancer
and overall mortality.'

However, some experts have said comparing eating red meat and other
protein to smoking could be putting across a dangerous message by making
people think that there's no point in giving up smoking if their
scrambled eggs are more likely to give them cancer than the cigarettes.

Salmon fillets, while considered a healthier source of protein, still account for 40% of your recommended daily intake.

It's also worth noting that on the other hand, the study suggested there are benefits to eating plenty of protein in later life. Dr Crimmins said: 'We also propose that at older ages, it may be important to avoid a low-protein diet to allow the maintenance of healthy weight and protection from frailty.'

Sources of protein like fish, chicken, grains, pulses and vegetables are considered to be the healthier options.

Ever get the feeling that just when one study tells you one thing, another will tell you the opposite? Would findings like this make you likely to eat less protein, or do you think they're just another statistic not to worry about? Leave us your thoughts in a comment below.

This is typical scaremongering and a distortion of the facts. The problem is not a high protein diet, but what else is taken in with the protein. The Inuit (Eskimo) peoples of the North have a diet consisting almost totally of whale, seal and salmon, and is also high in fats, with virtually no vegetables or fruit, yet they have a very, very low incidence of heart disease, cancer or diabetes, except, of course, where they live in settlements where the western diet is followed. The Inuit diet also has a good ratio of Omega 3 to Omega 6 fats, about 1/1, whereas our western diet has a very bad ratio, typically 1/20. (Up to 1/50 for junk food lovers). Also their diet contains NO refined carbohydrates - no refined sugar, no processed foods, in fact no 'so called' food manufactured in chemical factories. In addition, their wild animal food is NOT factory farmed, nor is it injected with synthetic growth hormones, or antibiotics. Where are the references to the research so that we can see what it actually says?
