Chocolate Bad, Salt Good?

So this Scottish wowser is calling for a tax on chocolate. Chocolate, he declared on the radio this morning, is 'a major player in the rising obesity crisis' (and obesity is, he points out, 'a mushrooming problem'). He's especially indignant about the good press chocolate has been getting lately, giving people the impression it's good for them. Well, that depends, of course, on what you call chocolate. In my book, proper chocolate begins at 70 percent cocoa solids (and ends some way short of the all but uneatable 99 per cent). Unfortunately, what most people regard as chocolate has percentages in the 20s and is mostly fat and sugar. The obvious thing to do - and I've been saying this for a long time - is to tax sugar, a substance which has no place in the human diet. Best, indeed, to tax all sweeteners, as they only encourage the 'sweet tooth' and make us fat. Sole exemption - honey, because I like it and therefore conclude it's health-giving. Sorted.
I also like salt - and there's good news on that front. It may kill you, but at least you'll die happy. Of course, like all such 'findings', this should be taken (hem hem) cum grano salis.
