I recently read an article that was published in 1929 in the Journal of Biological Chemistry, and I want to summarize it for all of you. It is titled “The Influence of Cereals Upon the Retention of Calcium and Phosphorus in Children and Adults.”
Keep in mind, cereal as we know it today was invented in 1877, and the Kellogg company was founded in 1906. All of the first cereal producers were Seventh Day Adventists and staunch vegetarians and believed that eating cereal for breakfast was better for humans than eggs or meat. (Side note: The Kelloggs believed that we would have a less promiscuous culture if everyone ate cereal ;)).
In 1924, Wheaties were invented: the first cereal aimed at kids, with sugar as one of the ingredients.
