I assume a lot of fruit, fish and meat people buy has no barcode unless you only buy stuff at a supermarket

How much of your daily intake comes from food that has a barcode on it?

I typically just measure ingredients and log it in Cronometer.

Nearly all food in the US has barcodes.

Produce, meat, etc might not always, but simply search those the same as you'd ask ChatGPt.

Personally everything that is not produce

Even the meat, i usually buy packaged
