Salt? Good question.
Im waiting for the food industry to wake up and offer "reduced salt" food items, just as they did with fats and sugars in food. Potato chips, fries, crackers, all food items need way less salt.
And they can reduce salt without harming the flavor by "dusting" food items with smaller dust-like salt particles. The flavor stays the same, with a lot less salt intake.
Salt is just as bad as sugar and fats when it comes to food.
I cannot believe not one name brand potato chip company has not come out with reduced salt chips.
