This is a scientific article I don’t expect you to read (unless you want to), but my interest is always on realizing and expressing how I and many believe that the food industry is so knowledgeable and uses this most physiological human nature to get us to eat more of their food. This is one of the main reasons why I think this generation has succumbed to the twin epidemic of diabesity. Food everywhere, billboards, television...you walk into a food place and the smells of food are abundant...our insulin is constantly triggered. This could not have been so in the previous centuries.
"... seeing and thinking about food and that individuals showing this response show a greater tendency toward weight gain in a food-abundant environment."
