In the text, the word ironically (paragraph 2) introduces

Are any foods safe to eat anymore? The fears and the facts 48 49 50

    Food was once seen as a source of sustenance and pleasure. Today, the dinner table can instead begin to feel like a minefield. Is bacon really a risk factor of cancer? Will coffee or eggs give you a heart attack? Does wheat contribute to Alzheimer’s disease? Will dairy products clog up your arteries? Worse still, the advice changes continually. As TV-cook Nigella Lawson recently put it: “You can guarantee that what people think will be good for you this year, they won’t next year.”

    This may be somewhat inevitable: evidence-based health advice should be constantly updated as new studies explore the nuances of what we eat and the effects the meals have on our bodies. But when the media (and ill-informed health gurus) exaggerate the results of a study without providing the context, it can lead to unnecessary fears that may, ironically, push you towards less healthy choices.

    The good news is that “next year” you may be pleased to learn that many of your favourite foods are not the ticking time bomb you have been led to believe...
