In other words, I mean, even if 0 blood group people are somewhat more at
risk of duodenal ulcers, what should they do?
1. Eat their soluble fiber (as everybody should). Yet, not overeat it.
2. Eat lots of soluble fiber, more than other people should.

I guess the correct answer might be no. 1.
In that case, there is not really a specific diet for each blood group, but
- at most - a specific reason to follow a certain recommendation in a
generally correct diet.
What do you reckon?
