I don't know too much about juicing; can you give an idea of how this would work? I would think it would be very difficult to do, because different people would put different items into the juicer, and in different quantities, so establishing a food or foods on the site for everyone to use might not be accurate.
It would probably be more accurate to create a custom food within your account on the site with the fruits and/or veggies you use and log it in that way.
