What was the orginial purpose of Kelloggs corn flakes and grahan crackers?

Kellogg's Corn Flakes and Graham Crackers were both originally created as health foods.

Kellogg's Corn Flakes were invented by John Harvey Kellogg, a Seventh-day Adventist minister and physician, in the late 1800s. Kellogg believed that a diet of bland, healthy foods could help to reduce sexual desire and promote good health. His cornflakes were originally marketed as a "breakfast food for invalids," but they quickly became popular with the general public.

Graham Crackers were invented by Sylvester Graham, a Presbyterian minister and nutritionist, in the early 1800s. Graham was also a believer in the power of healthy eating, and he developed his crackers as a way to provide a nutritious alternative to other processed foods. Graham crackers were initially made from unsifted wheat flour, which gave them a coarse texture and a nutty flavor. However, they later became popular with refined flour, which made them lighter in color and more palatable.
