What are the long term effects of monosodium glutamate?

It has been incriminated to cause wide range of effects comprising retinal degeneration, metabolic disorders, endocrinal disorders including reduced fertility rate in both male and female experimental mice and rats following neonatal exposure.

What is MSG and how does it affect the body?

Effect on brain health For starters, it acts as a neurotransmitter — a chemical substance that stimulates nerve cells to transmit signals ( 1 , 2 ). Some studies claim that MSG can lead to brain toxicity by causing excessive glutamate levels in the brain to overstimulate nerve cells, resulting in cell death ( 2 , 7 ).

How does monosodium glutamate affect the environment?

The toxicity of MSG wastewater on the growth ability of seeds of Chinese cabbage and wheat were also observed. A research study done by Liu and Zhou [18] showed that monosodium glutamate manufacturing in China released ammonia into the atmosphere. This man-made excess ammonia can cause respiratory health problems [19].

How does monosodium glutamate affect the taste of cured meat?

Based on the definition of umami (savory+salty), low level of MSG reduced the salty flavor because of its savory taste (Ikeda, 2002; Manabe, 2008; Yamaguchi and Takahashi, 1984). Therefore, it is essential to use MSG in the actual meat products such as pork patties.

Does MSG damage the brain?

When MSG enters the brain, not only does it kill brain cells, it wreaks havoc on brain functions. Many people react within 48 hours of ingesting MSG, even in minute amounts, which can make it difficult to trace back to the food source that caused the reaction.

Why do food products treated with monosodium glutamate as an ingredient often taste fuller or better?

MSG elicits a unique taste, known as umami, that is different from the other basic tastes (bitter, salty, sour, sweet) and thus enhances the complex flavours of meat, poultry, seafood, and vegetables. Ikeda’s discovery led to the commercial production of MSG from seaweed.
