I assume a lot of food is produced like toothpaste. I used to know a guy whose dad had a factory that produced toothpaste and shampoo for almost all big brands.

I assume a lot of food is produced like toothpaste. I used to know a guy whose dad had a factory that produced toothpaste and shampoo for almost all big brands. They did R&D for them and just put slightly different recipes into the branded boxes. That means that a lot of shampoos and toothpaste (and probably) are basically only slight variations of the same thing.
