For Ackera to determine the glycemic index, you must make sure all food-items in the meal have GI-values (must be 0 or positive value). Most food-items comes with a default value of -1. If one food-item in the meal has a negative GI-value, the glycemic index will always show n/a.
Ok , so how can i fix it?
Simply add a GI-value for the food-items that are missing GI-values. This can be done by updating an item. Check out the link below:
GI-value is found at the bottom, dont forget to scroll 🙂
