Make adding foods more user friendly

When I go to add new foods or edit ones that are already in there -- it's a nightmare! Please make this more user friendly. For example, add more options for serving sizes when adding the food. Every time I try to add something it only goes in at 100ml as a serving size, then, when I try to add an additional serving size (like an "each" option), I put in the actual serving size and suddenly it's completely different than the numbers I put in the first portion! I like many aspects of the app, but adding foods is incredibly complicated and not at all intuitive.
