Consumers do not demand the additives. What they demand is good taste, good texture, overall good tasting product, at a moderate price. And also the product must have a long shelf life; they don’t like it if the product is spoiled 2 or 3 days after they buy it.
The only answer to this is plenty of additives, preservatives etc. So consumers are not asking for additives and preservatives. But by the demand they place on their food, they are indirectly permitting the use of additives and preservatives.
That is all part of advertising, PR, countryboy. Word ‘healthy’ means nothing; it is not defined in government regulations somewhere. My definition of healthy maybe different from your definition of healthy. So you can hardly blame the food industry for using labels such as healthy, nutritious, etc. for their products. Unless and until governments and courts define exactly what is meant by ‘healthy’ or ‘nutritious’, it will continue.
My granddaughter in grade 4 knows the definition of both health and nutritious, too bad common sense is in such short supply. The only advantage McD's has over Denny's is McD's can deliver the "meal" faster, Denny's wins hands down for both value and being fit to eat. In fact you can get about 3 times the meal for about 25% more.
