Sourdough fermentation reduces phytic acid by 62% versus 38% for yeast alone. Research (Lopez et al., J Agric Food Chem 2001) shows this improves mineral absorption and lowers glycemic response. Sourdough is also gentler on digestion than standard wheat bread — fermentation breaks down the carbs that cause gut discomfort. Sodium runs 595 mg per 100 g, so weigh your slices.
How should I track Sourdough Bread?
Sourdough Bread is a good source of iron. Bakery products like Sourdough Bread 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.
