From the archives: What is junk food?

Per reader request, here is the link to the classic article, Junk-foods and empty words, by Dr. Johan H. Koeslag, head of the Department of Medical Physiology at the University of Stellenbosch, Tygerberg, South Africa, explaining what junk food really means. This delightfully entertaining article captured the disconnect between science and beliefs about food and what it means to eat healthy. This was first covered in Mythology of health food and junk food, which revealed the real brain food.
