I am thinking that you are talking about the popular term referring to the ongoing battle against obesity. If I am wrong, ignore my answer. Here is what I think:
It is a very contradictory thing. Right now on American TV there are around 5 celebrities getting paid high dollars to advocate Jenny Craig, Atkins, Weight Watchers, Nutrisystem, the Organic Juice and the South Beach diet. On the same token, we have highly paid Chefs advocating for "foodies" and food shows featuring all kinds of food are hitting the HD market.
So, common sense tells us that moderation is key. But yet, there is another market always attacking- The fast food market.
In the US, for example, gourmet and healthy food is extremely expensive compared to the $10 dollar and $5 dollar pizza deals from Pizza Hut and Little Ceasar's respectively. Every fast food restaurant as a very convenient "dollar menu" now, for which an average college kid could get a 5 course, highly caloric, and extremely junkie meal for $7 including tax.
On top of that, every commercial linked to an upcoming holiday is about the chocolate, candy, junk, or outrageous meals you could be eating.
So, on one hand we have paid sponsors telling us to join a diet plan while another is telling us to love food, and the mainstream media is telling us to save money by eating junk.
Bit ironic, isn't it?
