Ever wonder why we prefer some food over another for no reason?

Another one from Mat...

Ever wonder why we prefer some food over another for
no reason? For me, naturally I will prefer fish over
poultry or meat, which I myself cant figure out the
rational explanation for that until 3 weeks ago when I
found a book in MPH about eating right based on your
blood type written by Peter D'Adamo.
This book describe about the foods suitable for us
based on our blood type as a remedy to a blood type
can be a poison to another. As for me, with A blood
type, fish is the best source of protein, as people
with A blood type is having less stomach acid for
digestion. Therefor poultry and meat are foods that
should be taken lesser if not to be avoided totally.
People with A blood type also tend to have this
indigestion problem due to low secretion of stomach
acid, the doctor recommended a king size breakfast and
a small dinner to overcome this problem. Among other
things recommended, people with A blood type also
should go for more softer protein source like soy
extracts e.g Nattou, Tempe(this one really shocked
me)etc. Have a good night sleep, make sure you already
in bed by 11pm so as to keep cortisol level low and
keep it consistent so as not to disturb the circadian
rhythm.
It is critical to keep the cortisol level low as A
blood type persons tend to be weak to allergy, perhaps
due to short of strong source of bovine antibody from
meat. Therefor intake of green vegetables for various
type of minerals could support this deficiency.
There is so much new finding in this book that can
help us and our family live a healthier life. I will
try to get more info posted to the blog for our benefit.
