Wholemeal Wheat Sourdough Bread (US) and IBS: what to know

For an IBS lunch record, note how much wholemeal sourdough went into the sandwich, including any extra bread eaten alongside it. The bread's low result does not describe fillings, dressing or spreads. The US preparation should not be treated as a universal rating for all wholemeal or sourdough loaves.

Gut-friendly ways to eat wholemeal wheat sourdough bread (us)

Weigh the bread on its own before assembling a sandwich. Hand-cut slices are especially worth checking because thickness can vary across the loaf. Keep the product description when changing brands or grains. Light rye sourdough and oat sourdough have separate portions and group patterns; choose the matching guide for a substitution.
