Why was peanut butter invented?

Peanut butter was first invented by the Inca, but made a reappearance in North America due to its rediscovery by John Harvey Kellogg in 1895. Peanut butter was made with the purpose of helping older people who couldn’t chew solid foods gain nutrients such as protein. Although it made a reapperance in 1895, it was sold to the public in 1904.
