I was in the process of experimenting what the effects of eating the different food items, when I stumbled upon this pretty amusing bug regarding carry weight and fruits:
It's funny enough that you can take 1 apple, and put in a container (like bucket, pot or basket), and then you have a bucket of apples. But even more so, that a container will weigh a lot if you put it into your inventory empty, but if you take any fruit or vegetable (e.g. apples, oranges, or tomatoes) and put it into the container on the ground, then put the filled continer in your inventory, it will weigh nothing! If you then eat the fruit from the container in your inventory, the container regains its original weight. Like the fruits make the container weightless??? :-)

Edit: The weightless efect does not work if you load the container when it is already in your inventory.

Btw, it seems that at least some of the food items have different effects depending on whether you eat them alone or from a container. Can anyone confirm this?
