Why hasn't the problem been solved yet?

Tesco has agreed to have "traffic light" labelling on its food, informing idiots their customers which foods are healthier or have less salt or more of whatever happens to be the fashionably good or bad ingredient. I seem to recall this being tried in other stores in the past and then quietly dropped as being too expensive and of no use whatsoever. Apparently, my memory is slightly at fault.

The retailer has for years resisted using the colour-coded system on its products. The on-the-packet traffic light label grades food as red, amber or green depending on how nutritious it is, with red being the most unhealthy.

Instead, Tesco has since 2005 used a ‘guideline daily amounts’ (GDA) system which shows the percentage of salt, sugar and fat in a product but does not involve colours.

However the chain, which has annual sales of £47 billion in the UK, said that following new customer research it will now develop a “hybrid” labeling system incorporating traffic lights and GDA.

The move will bring it in line with rivals Sainsbury’s, Asda and Marks & Spencer who have used hybrid labeling for years.

(Incidentally, why is the Telegraph using American spelling?)

Naturally all the so-called charities, lobbying organizations and quangos who deal with health, diet, obesity and other related matters rushed in there joyfully, acclaiming this latest move against something that does not seem to go away.

Given the number of these organizations and the extent to which food manufacturers and retailers have been bullied into providing perfectly pointless information (knowing how much salt there is in something is one thing, being told how much is red, amber or green is something else) surely by now we should have no disorders, syndromes or illnesses caused by the "wrong" kind of food, let alone obesity.
