In most countries, health and nutritional claims that are made to present or promote foods to consumers are strictly regulated.

In Europe for example a claim that a food is a source of fibre (or any claim likely to have the same meaning for the consumer) may only be made if the product contains at least 3 grams of fibre per 100 grams of bread, or at least 1.5 grams of fibre per 100 kcal. A claim that a food is high in fibre (or any claim likely to have the same meaning for the consumer) may only be made if the product contains at least 6 grams of fibre per 100 grams of bread, or at least 3 grams of fibre per 100 kcal.

It is important to note that all breads contribute toward daily fibre intake. In general, as they contain more than 3 grams of fibres per 100 grams of bread, brown breads and multi-cereals breads are sources of fibres. Wholegrain breads are rich in fibres as they contain more than 6 grams of fibres per 100 grams of bread.
