White bread has 2.3 g fiber per 100 g – less than half of whole wheat. A meta-analysis (Reynolds et al., Lancet 2019) found higher whole grain intake reduces all-cause mortality by up to 30%. Commercial slices are relatively consistent, but brands vary from 25 to 40 g per slice. Check your brand's label once and use that weight for all future logs.
How should I track Bread, white, commercially prepared?
Bread, white, commercially prepared is a good source of iron. Bakery products like Bread, white, commercially prepared vary more than you would expect — even pieces from the same batch can differ by 25–50 g. Research on portion estimation (Almiron-Roig et al., Appetite 2013) shows that people are particularly bad at estimating baked goods because size, density, and moisture all vary. The simplest fix: weigh a few pieces with a kitchen scale and you will quickly learn what your usual portion actually weighs. This one-time calibration makes all future logging faster and more reliable.
