Doesn't seem accurtate

Fleshbits

I am trying to Keto diet and cronometer was suggested to me. I've been trying it out for 2 days now. Both days, according to the app, I went way over my limit on carbs. Today, I checked what it was reporting as having the highest carbs. Red Onion and Bell Pepper? huh?

According to the app, 1 cup of chopped red onion has 21.3g of carbs, which means that is all I can eat all day...
According to the internet, it has 13.

Bell Pepper is about double too.

I dunno if these are accurate and with so little wiggle room, I need pin point accuracy.

Hi @Fleshbits, Welcome to Cronometer! Absolutely, it is a must to pinpoint accuracy! For this reason, we choose data from the best sources! Our high quality data from USDA and NCCDB is lab tested, and data marked CRDB from branded products is reviewed and edited by our curation team before being added to our public database!
Two very important things to keep in mind are:
1. 1 cup of your chopped onion may be a very different actual amount than my chopped onion! How firmly you pack the cup, if you are using a UK or US cup or how finely you chopped the pepper can all play a factor in the difference! For this reason, try weighing your foods instead of measuring them by volume! Sure, measuring by volume is easier, but weight is far superior for accuracy!
2. Choose your data source! NCCDB and USDA contain lab tested data with the most nutrients listed. Try to use these sources as much as possible. While scanning a barcode may be easier, the lab tested data is going to be the most complete and accurate.
