Whole Grain Oat Cereal Biscuits (UK) and IBS: what to know

In an IBS breakfast record, note the number and dry weight of the cereal biscuits before adding milk. Fruit, sweeteners and other toppings are separate contributions to the meal. The low cereal rating is a portion result, not a promise about how a full breakfast will affect an individual.

Gut-friendly ways to eat whole grain oat cereal biscuits (uk)

Place dry biscuits in a tared bowl, including any broken pieces from the packet. Add milk or yoghurt only after recording that weight. For crushed biscuits used in a recipe, calculate the dry cereal share in each serving. If switching to gluten-free corn flakes, follow that food's guide and assess its formulation rather than matching bowl volume.
