NourmioWhat does a blank sugar value mean in a food diary?
See what Nourmio records when sugar is unknown, how a partial daily total works, and when to enter a label's 0 g.
Leave total sugar blank when your source gives no value. Enter 0 g when the matching label reports zero for total sugars. Nourmio can save calories with sugar left blank. If some entries have known sugar values, their sum can appear as a partial total.
Use the value you can verify
A blank sugar field means you have no number to record. The USDA makes this distinction in its branded food database: some nutrients have no supplied value. A missing field leaves the amount unknown. It can still be useful to save the calories when you have them.
If the matching package lists 0 g Total Sugars, use that reported value for the serving shown. The label can round small amounts to zero. Check the difference between Total Sugars and Added Sugars before copying the number.
What happened when sugar was left blank
In a Nourmio iPhone recording on November 8, a banana photo produced a calorie and sugar estimate. The person recording cleared the sugar field and left the 118 g portion and the calories in place. The saved entry showed Sugar unknown and 105 kcal. The Sugar view of Today also showed Sugar unknown and flagged the missing entry.
A second recorded entry used the estimated 12.2 g total sugar per 100 g with a 120 g portion. That works out to 14.64 g. The diary displayed 14.6 g. The recordings show what the app estimated and saved. They do not measure the banana’s nutrition.
What happened when 0 g was entered
A third entry used the same 120 g portion and 89 kcal per 100 g as the second. For this test, the person recording entered 0 g in place of the sugar estimate. The saved row displayed 0 g and 106.8 kcal. The zero was a test input. The recording did not establish that the banana contained zero sugar.
Read the partial total
The day showed 14.6 g after the second entry and kept that total after the zero was saved. The app still flagged one entry with missing sugar, the original 118 g entry. The calories from all three entries were included. The displayed calorie total went from 211.8 kcal to 318.6 kcal.
If you see a partial total, open the entries and look for Sugar unknown. Leave the field blank if you cannot confirm an amount. If you have a matching label, check its unit and portion before entering the value. The same check helps when you review an AI food estimate.
