If you want more eye-openers, read the book Fast Food Nation - or watch the movie (warning - it's intense, and deserving of its R rating). Sobering stuff.
Not only were those 50s hamburgers much smaller, they probably didn't contain all the hormones which I believe can mess up our bodies and contribute to obesity and many other health issues.
Also another book, The End of Overeating, discusses how foods are designed by the food industry to hit as many taste receptors and pleasure centers in our brains as possible.
