The danger of growing up surrounded by endless sweet and salty industrial concoctions is not that we are innately incapable of resisting them but that the more frequently we eat them, especially in childhood, the more they train us to expect all food to taste this way.

Learning to cook in the 1990s, I thought 'proper olives' meant black. The benchmark was Kalamata from Greece: purple-black with an almost mushroomy depth of flavour. Other fine examples were tiny Coquilles from Nice and plump round Tanches from Nyons.

I'd rather have a good food - lots and lots of different varieties of good foods - than search for something perfect.

Protein, we keep being told, is the vital nutrient that will give us a boost. It will burn fat, build muscle, reduce tiredness and kill our hunger pangs. Maybe if we shake enough protein powder into our daily smoothie, we will actually morph into Gwyneth Paltrow.
