Comparing foods based on energy, chemical content, fiber, and meal compositions is difficult because of the complexity and the lack of data on physiological responses, regardless of the amount of processing. Since many in the general public are confused about nutrition recommendations, simplifying messages may be of help: unless the simple message adds to confusion. More rigorous and standard definitions for food and nutrition research and communication are fundamental to the development of healthy, safe, inexpensive, shelf stable foods.
