Cereal syn values
Most plain cereals qualify as a Healthy Extra B at a measured portion, making breakfast effectively free. Flavoured or sugar-coated versions of the same cereals usually do not qualify — original Weetabix is HExB, chocolate Weetabix is not. Weighing the portion matters more than the brand.
