As supremely health conscious as he is, even Mayor Bloomberg thinks it’s nutty that a state assemblyman is proposing to ban the use of salt in restaurant cooking.

“I think it’s ridiculous,” the mayor said this morning, referring to Bronx Assemblyman Felix Ortiz’s bill that would prevent chefs from adding a single grain of salt to a restaurant meal.

Bloomberg is pushing his own campaign against salt — but it involves a voluntary reduction by food manufacturers over five years, not an outright ban.

“You have to have salt when you cook,” observed the mayor on his weekly WOR radio show.

“I do. I use too much salt already myself. But also it makes a lot of foods, the way you cook them and bake them– salt is a real ingredient. So I don’t think that’s the right thing to do.”
