IS nothing sacred? Bacon is part of our national heritage, the staple of many a meal and loved by millions for its yummy taste.

Unfortunately for aficionados, we are now being warned of a new threat ...death by bacon butty.

An alert has been issued after the discovery that customers at certain roadside vans are eating more than their entire daily quota of salt by munching through just one of the sarnies.

It’s a fair bet that anyone eating one will go on to consume a lot more salt in other things during the day.

And that can’t be a good thing.

Unlike picking up food in the supermarket, it is not possible to analyse fat content, calorie level and salt grams on a takeaway menu.

So any work to make the food healthier can only be a good move – especially in areas where levels of obesity and heart disease are high.

If in doubt, ask this question: Who in their right mind would want to feed their loved ones food which is killing them?
