Monosodium Glutamate & Hydrolyzed Protein - Industry spokes persons and publications of various national governments assure us that Monosodium Glutamate ( MSG ) is good for us, with no detrimental effects.
Such assurances are totally meaningless to those of us who find even small amounts of Monosodium Glutamate ( MSG ) can cause a feeling of swelling head, headache, spaciness, anxiety, and make it difficult to sleep.
(Going on a chocolate binge can do the same to me.)
Hydrolyzed Protein ( HP ) is made from various foods (such as soybeans, corn, wheat, or milk whey) by acid hydrolysis.
This is usually made into flavor enhancers for processed foods. Hydrolyzed Protein ( HP ) is often used with Monosodium Glutamate ( MSG ).
HP causes me pronounced after-taste and mouth / tongue swelling, which keeps me from using numerous "quick meal" kits.
Learn from others, but trust your own observations.
