Because variety is very important on a fruit-based diet, having this chart around has been invaluable. Growing up, I learned that 15g carb (one serving) of fruit amounted to 1/2 of a medium banana, one apple, or one orange. But what about for sapodilla, mango, papaya, black sapote, cherimoya, and all the other multitudes of yummy fruit out there waiting to provide delectable nourishment to our bodies? With this chart, I can know. :)
The two charts I have posted below were created during different phases of my eating. At first, I was eating small, measured amounts of fruits, and wanted to go by "serving size". The second chart was made after getting comfortable with a fruit-based diet, and shows carb amounts for whole fruits, which is now more realistic for my eating style.
One of the charts uses carb factors. Here is an introduction to carb factors, for those who are unfamiliar with it: simply weigh a fruit, using grams. Then multiply that particular fruit's carb factor by its weight in grams to get the number of carb grams in the weighed amount of the fruit you are eating.
Another very handy tool is a nutrition facts scale. We bought one of these last year and love it. Here is how they work. I can put my (plastic) blender jar on our nutrition facts scale, zero the scale, add in however many bananas I want, choose "bananas" as my food on the scale, and then the weight, calories, and carb grams are figured out for me. It's really cool. My hubby uses the memory function and adds multiple different fruits to the blender jar in the same way, to come up with his total calories and carb grams (and other nutrition info) for his smoothie.
Someday I will get this all down in a book. For now, here are my charts and the nutrition scale we use, provided in the hopes that it can be as helpful to your diabetes control as it has been for mine. :)
