The criteria are very different, PIP is looking at the assistance you need with eating, ESA is looking at the function of eating and specifically whether you can "Convey food or drink to the mouth" and whether you have problems with "Chewing or swallowing food or drink". Issues that you obviously have with the preparation and presentation of food will not be counted for ESA.
