Kellogg was the director of the Battle Creek Sanitarium, a long-term hospital he ran using holistic methods. As a Seventh-day Adventist he believed in, and practiced vegetarianism, abstinence from alcohol and tobacco, as well as regular exercise and enemas.

While Kellogg didn’t want to add sugar to corn flakes, his brother did. This dispute led them to establish separate companies. Unfortunately, his brother’s corn flakes (containing sugar) would eventually become the Kellogg Company staple.

Here’s the best part…Kellogg’s rival, Post Cereals, was started by one of Kellogg’s patients, Charles William Post. And according to Kellogg, Post stole the recipe from the safe in his office.

I learned about this fact from: “Salt, Sugar, Fat – How the Food Giants Hooked Us” by Michael Moss and http://en.wikipedia.org/wiki/John_Harvey_Kellogg
