In the USA there are various products from Fibre One (General Mills). These have a very high fiber content, which has a good effect on the digestive system. Especially in today's fast-paced world, a high-fiber diet is not always easy. Even with enough vegetables, fruit and liquid intake, it is not always possible to get the digestive system going.
I am absolutely certain that these products would sell very well. They taste very good, and there are a number of products from muesli bars to cereals and bread.

It would be really great if Migros had something like this soon.
Have a look :-) Merci!
