I'm going to go out on a limb here, but I think that the dishwasher and the microwave are contributing to the obesity problem in this country. This thought came to me the other day when, in 30 minutes, I covered some very healthy strawberries in some very unhealthy chocolate. I started with washing the berries and ended with washing the dishes and still got it all done in 30 minutes thanks to the microwave. I even used two different kinds of chocolate.
For Halloween each year I make chocolate covered caramel apples. When I was a kid this was the type of thing you got once a year at the fair, twice if your family went to Gatlinburg. Can you imagine the time and mess involved in making such a treat before microwaves and the clean up before dishwashers? No wonder people didn't make these for themselves. Now all it takes is a corning ware dish, a microwave, and a dishwasher. I can knock those things out in minutes.
Later I got to thinking about all the things I make quickly and easily that a few years ago would have taken all day and messed up every pot in the kitchen. It would quickly become a dish not worth the trouble or best saved for special occasions.
What I'm realizing here is that if you take a treat normally reserved for once a year and invent something that allows you to make it easily once a month then it stands to reason that people will start to put on some extra weight unless they restrain themselves. I don't know if you've noticed, but our generation is not real big on restraint.
