Eliza, there was something on the radio a couple of days ago about diet and "UPF", which means "ultra-processed food".

They said there was an experiment where one group of people was fed a diet of supermarket packet food and the other group a diet with the same amount of fat and sugar and salt and suchlike, but freshly made with proper fresh ingredients. The ones on a proper diet didn't get fat and some even lost a bit of weight but the ones eating supermarket packet food all put on weight.

The way to tell the difference is to read the labels on the food packets and if there is a long list of chemicals and things you've never heard of, that means it is UPF and IT WILL MAKE YOU FAT.

I will look at the crumpet packet next time and read the ingredients, but meanwhile you can carry on with the butter and cream and milk.
