For my readers outside of the UK, Dr Ben Goldacre's analysis of the problem with Gillian McKeith will not seem very compelling. However, Goldacre's discussion of how McKeith is essentially a charlatan offers him the opportunity to open up a much more interesting and wide-ranging topic for discourse: how socio-economic inequities are what actually pose the greatest threat to health in this country (and within other nations). Here is a pertinent extract from the article.
In reality, again, away from the cameras, the most significant “lifestyle” cause of death and disease is social class. Here’s a perfect example. I rent a flat in London’s Kentish Town on my modest junior doctor’s salary (don’t believe what you read in the papers about doctors’ wages, either). This is a very poor working-class area, and the male life expectancy is about 70 years. Two miles away in Hampstead, meanwhile, where the millionaire Dr Gillian McKeith PhD owns a very large property, surrounded by other wealthy middle-class people, male life expectancy is almost 80 years. I know this because I have the Annual Public Health Report for Camden open on the table right now.
This phenomenal disparity in life expectancy – the difference between a lengthy and rich retirement, and a very truncated one indeed – is not because the people in Hampstead are careful to eat a handful of Brazil nuts every day, to make sure they’re not deficient in selenium, as per nutritionists’ advice.
And that’s the most sinister feature of the whole nutritionist project, graphically exemplified by McKeith: it’s a manifesto of rightwing individualism – you are what you eat, and people die young because they deserve it. They choose death, through ignorance and laziness, but you choose life, fresh fish, olive oil, and that’s why you’re healthy. You’re going to see 78. You deserve it. Not like them.
