I had never heard of that blood types determine what the best diet is...I agree, pure nonsense.
I`m sure the above wasn`t meant as an argument, because there is just an unbelievable amount of the things we don`t know
yet. On the other hand, you seem to be intrigued enough by the vegetarian "fashion", wanting to experience it for yourself,
which can be considered only a good thing.
Of course, I`m not saying I have a firm view on this matter, but I`m not sure if there are any nutrition specialist
contributing to this topic and thought you guys just want to exchange some info and views, without falling into discussion
winning contest.
Actually, I have three friends that have blood type "0" who tried to live without any kind of meat for a longer period. The
"winner" was the one who was able to "sustain this diet" for a month, but they all became very weak and felt really bad after this experiment.
Perhaps there are other reasons behind all this, other than "0" blood type, I don`t know, but I know plenty of other people
(non "0" blood types) who are vegetarians for decades and just seem to feel great and it is showing.
As with other things, I`m open to interesting views and I must say that if someone wins me with his argument in regard to anything, then be it.
Good luck!
