Are there any careers that tie psychology into food or vice versa?

I love to make food and enjoy that as a hobby. I would love working for a food company or something because although I enjoy making food I would not want to be a chef because I like to take my time when I do make food. But recently I realized that I am very interested in the human mind. I love psychology. I love finding out how different people react to situations and am very nosey because of this. So are there any careers that you would say tie those two together in some way?
