MSG is a well known additive to enhance flavor in foods--again, because the "food" doesn't have good flavor on its own. But it can have devastating health effects. See the following quote.
"MSG is a major excitotoxin and is known to damage the part of the brain that governs many other systems in the body. This damage may appear as symptoms of the autonomic nervous system and endocrine system. Thus it can manifest in disrupted sleep patterns, food cravings, and persistent hunger, which often leads to obesity. MSG also induces migraine headaches, asthma attacks, behavioral disorders, depression, heart irregularities, arthritis, sinus problems and many digestive problems including diarrhea."- from the book ‘Is
MSG Safe?’, published by the Consumer’s Association of Penang

Read the list of ingredients on all the food you buy. If there are ingredients you can't identify, think about why you are eating them and what they might do to your health and that of your family. Then think about why they don't have to list ingredients in fresh whole foods. A banana is just-a banana. Rice is just rice.
