I am not entirely sure that i buy all this, but it appears otherwise quite worthy anyway once you are able to tolerate it. It certainly was used by British sailors for a long time. I think though it is convenient enough to add into your morning regimen. Add in a side of kimchee and a poached kipper and you have a perfect breakfast in my humble opinion.
It appears to be an excellent digestive stabilizer or tonic. Again it helps to be eating excellent food and scant cereals. skip the pancakes.
We will all learn to eat properly some day. Perhaps after we ban Krafts..
