If this magazine tells me a certain pair of heels is a "must-have", I want them. If it tells me how to bake a heart-shaped jam tart for summer picnics, I'll get the ingredients. And if it tells me how to detox or retox my diet, I'll make a mental note to stock up on lemons.

Or tequila, depending on what week it is.

But when my magazine featured an article on Prebiotics: The New Superfood Craze, I rolled my eyes.

Sure, I was down with the whole inner cleansing thing. I have my five-a-day covered, and I take vitamins when I remember. But it's fast becoming that everything we consume and ingest is being decided upon by its antioxidant value or whether it's fat-breaking or metabolism-boosting.

Don't have white grapes, have dark ones. And, instead of an orange, have a grapefruit. There again, an orange will help you fly, so, you should probably eat one of those too. Chop them up, eat them together with a spoonful of Greek yoghurt and some seeds for energy. That said, yoghurt is fattening and the contrasting acidity might cause you to bloat and feel tired mid lunch. What is there left?

"Dark fruits stop you ageing" was the headline in one tabloid not so long ago. Nope, I'm betting they don't. Still, that doesn't stop me being about £11 worse off every lunch time after a trip to M&S to buy a box of (plastic wrapped) grapes (so of course I don't mind paying 5p for being so uneconomical as to dare ask for a plastic bag).

But getting our heads around probiotics took long enough to grasp. The concept of actively putting bacteria into our bodies was alien to some and, to many, still is.

Probiotics, found in forms of live yoghurt, contain "good" bacteria and help to strengthen our natural defence and immune system, as well as aiding digestion and inner wellbeing. Prebiotics, found in foods like Jerusalem artichokes, unrefined wheat and raw oats, apparently work to support the actions of probiotics, helping to strengthen the immune system and benefit mineral absorption.

But is it all just one big con? Are we being sold revelatory health benefits or are we just being sold a ploy?

I'm tired of being told potatoes are cancer-fighting and goji berries hold the secret to eternal truth, so health shops can get away with selling them for a pot of gold per 200 grams.

Surely if we all eat a healthy, stable and varied diet, we'll get all our RDA of vits, pros, pres, antioxidants etc., without having to read daily bulletins about what's slowly killing us and what's going to give us superhero immunity.
