Divine Caroline has an article about the Ten Worst Artery Cloggers in America. At the same time, they also have an article on Ten Foods That Will Improve Your Mood.
As far as the first one, not very many of them are actually available in Canada. However, I am sure we have substitutes. The Domino’s Chicken Carbonara Pasta Bread Bowl, for example, sounds a lot like like something introduced at KFC recently -- a bowl (but not a bread bowl) with fried chicken, mashed potato, corn, gravy, and cheese -- just the thing to make up for a lipid deficiency. And I am happy to put a Double Big Mac up against a Triple Whopper with cheese.
Bad though they are, these are all best selling products because we are evolved to want sugar (in this case carbs) and fat -- and these products mainline their delivery to us like heroin from a junkie's needle.
Based on the other list, it sounds like one of the best food experiences that we could have would be to start outside on a sunny day with an edamame bean appetizer leading up to eating a lot of turkey. The accompaniments would be a lentil salad and a spinach salad, followed by a chocolate banana dessert. The sunny day would allow us the manufacture vitamin D through direct exposure to sunlight. All the other foods would max out tryptophan and folate (a vitamin B compound), and the net result would be a lot of happy people. Gotta try this...
