Using the recent anniversary of my birth as an excuse, Mr D and I seized the chance to go for a nice meal surrounded by grown-ups, before the only restaurants we get to patronise are those full of buggies and helpings of organic carrot.

We both enjoyed the meal hugely - unlike some of our fellow diners, who seemed to treat the place, despite the sommelier and linen tablecloths, rather as they would a corner caff.

But would I have enjoyed it as much if I had known how many calories were in my dressed crab, sea bream and Eton mess?

For such is the latest cunning wheeze of the Food Standards Agency, which is working with some major food chains to get the calorie counts of their wares displayed on menus.

It is also reported to be considering getting restaurants to "traffic light" their grub; highlighting what is considered to have a lot of fat, salt or sugar. Of course, a lot of processed and prepared food is swimming in fat, salt and sugar, and it is, of course, not a bad thing for consumers to be aware of what they are consuming, especially as health campaigners say one in six meals is now eaten away from the home. (Though unless they mean evening meals, that does not seem that much to me - can there be many people in this country who make it home for lunch on work days?)

It will also come in handy for those who are calorie counting, although I would suggest that coffee shops and pizza restaurants are probably best avoided by those dieters among us anyway.

But putting calories counts on some foods seems a bit obvious. While it might be nice to get a warning that a healthy looking sandwich is actually going to load you up with about 900 calories and it might encourage food chains to make their goods healthier, who wants to know how many calories are in a slice of chocolate fudge cake?

You don't eat such foods as part of a balanced diet, but because they taste nice, or because it has been raining for three days, or because if you don't scoff something sugar laden in the next five minutes you might burst into tears.

And no amount of calorie warnings are going to put me off those kinds of treats.
