I read a book a couple of years ago--Eat Right For Your Type. According to the book, each blood type should eat differently and even exercise differently. So what is healthy for an O isn't healthy for an A.
O's are the oldest blood type--the Hunters--the meat eaters. Then people began to establish stable and permanent communities and grain farming--and blood type A appeared....and so on.
O's thrive on meat.
A's on a vegetarian diet
I don't remember much about B or AB.
The book also explains difference in basic personality types.
O's are said to thrive on intense physical activity and carry a genetic memory of stength, endurance and self reliance.
A's adapted to live in a cooperative society. Clever, sensitive, and tightly wound. They are more likely to bottle up frustrations because the need to get along with neighbors to survive. Inner stress. Relaxation exercises are recommended as opposed to intense work-outs.
Anyway, it's big in Japan and there is much discrimination against certain types. My friend who grew up in Japan said that people are hired for certain jobs according to blood type.
I'm not sure I buy into all of that. However, I did "eat right" for type A for a couple of months and never felt so good in my life. Maybe because I was only eating health food store types of food. I was warm all the time--I think my metabolism was running at full capacity...and had energy like a 2 year old.
I believe in creation--so I'm still trying to figure out what blood types Adam and Eve were--AO and BO???
I heard this theory, which not surprisingly can be traced back to the 1930s, is still big in Japan, where it causes widespread discrimination. It’s also used by many matchmaking services there. Type As are supposed to be more conventional, Bs more SP-ish, and so on. Does anyone here believe this theory?
Interesting that you ask. I have been getting into this, stemming from when I found out your blood type is connected to your needed diet. The description of my blood type seems to match my personality, but it is still pretty general. Alot of Eastern theories on mind, body, and soul seem to be pretty wholesoom, and having some truth, so I think it's worth considering for sure. Sorry if that wasn't much help.
