This diet is well intentioned, but it lacks scientific evidence to support its claim that we should be regulating what we eat by our blood types.  It is hard to determine whether this would be a healthful diet to follow, as there are no recommended meal plans – you merely select what to eat from a list based on your blood type, so that you can avoid the appropriate “protein lectins”.
