A. Ensure that you are entering the food items correctly. Double-check the spelling and try using different variations of the food name. If the food item is not recognized, consider using the barcode scanning feature if available, or manually inputting the nutritional information if you have it.

B. If the app has a community feature, check if other users have logged the same food item. You can also report the issue within the app if there is an option to do so, which may help improve the food database over time.
