I'm also curious why we haven't seen a chorus of "I gave up msg and lost 10...25...50...100 pounds!" which I would expect to see if there was this effect.
Most likely because its extremely difficult to "give up MSG"...as its in just about everything we eat nowadays. You could say just eat fruit, veggies and meat and you will be naturally free of MSG right???...Wrong.....its actually found its way into the fresh produce via growth enhancers. Auxigro is a growth enhancer (ever wonder how the strawberries got to be so big?) that contains 30% glutamic acid. Yup...thats MSG...and its used on a wide array of crops...vegetables, fruits, grains, and nuts.
Its virtually impossible to say "I gave up MSG"....what on Earth would you eat?
Furthermore....thanks to the widespread use of MSG on the crops....its now found its way back into baby food. At one time MSG was removed from all baby food products but with the use of Auxigro and other growth enhancers unfortunately there is no guarantee your babies food will be free of MSG.
