I think last year they changed the beef they were using in their hamburgers. I used to like it, but since last year I can’t eat it.
As a side note - a week or so ago I ordered a sausage mcmuffen because I missed breakfast and ask for some water to take a pill. They charged 20 cents for the water...
I used to really enjoy sausage McMuffins... but the last two or three times that I got them I noted feeling “odd” afterwards. Not “sick to my stomach”, but like it messed up something with my nervous system, like with dulled senses. A foggy feeling.
I suppose it is MSG, or as they call it now (because they are so smart and the consumer is so uninformed), “Yeast Extract”.
I think I am done buying them.
I suspect that the change in taste last year has to do with McD's decision to stop washing the burger meat in ammonium hydroxide: http://buzz.naturalnews.com/000893-McDonalds-ammonium_hydroxide-hamburgers.html
