A Pizza Express supermarket pizza contains almost half the salt of the takeaway version.
That's the result of research by CASH (Consensus Action on Salt & Health), whose most eye-catching factoid is that the Adam & Eve pizzeria in Mill Hill serves pizza saltier than Atlantic seawater.
According to CASH, salt in one’s diet can triple the risk of having a stroke, and as 3/4 of it is hidden in food rather than shaken over it, the content of processed food is key.
The general finding that supermarket pizza is often healthier in terms of salt content than takeaway pizza reflects the general counter-intuitive pattern that supermarkets (where labelling informs consumers) generally take greater care about the health of their customers than the restaurant trade, where famous chefs -- often smokers who need salt to taste anything -- continue to try to persuade the world that the addition of salt is fundamental to gastronomic good taste.
