change food units
 

i am trying to enter my food on the iphone. The only uint I get is grams. How can I change it into another unit, slices or pieces for example?

Why not just input the food the way it was intended. (One-half of a Dole fruit pear @) 13 Carb (grams). This information will be more beneficial to your doctor and nutritionist. They don't really care what you at, they just want to see the carb count, bottom line.
