Q&A

• What recent research reveals about the role of MSG in health and metabolism?

  Recent research shows that MSG plays a vital role in metabolism and could be a healthier alternative to fat and sodium. Investigations into whether regular consumption of MSG is linked to obesity and adverse effects for some individuals, but moderate consumption of MSG is generally safe and enhances food flavor.

• How did the term 'Chinese Restaurant Syndrome' originate?

  'Chinese Restaurant Syndrome' stemmed from prejudices against Asian eating customs and use of MSG, fueled by biased journalism and inconclusive studies that led to fear-mongering about MSG and its effects.

• When and how did MSG become widely used?

  MSG, created by Dr. Kwok in the early 20th century, became a kitchen staple in Asia by the 1930s and then globally by the mid-20th century.

• Who discovered the molecule responsible for umami flavor?

  Dr. Ikeda Kikunae discovered the molecule responsible for umami flavor, recognized as one of the five basic tastes. It is produced by unique molecular mechanisms, particularly the release of glutamate from proteins when cooking or fermenting certain foods.

• What are sodium and glutamate, and what roles do they play?

  Sodium and glutamate are essential for our diet. Glutamate plays a key role in digestion, muscle function, and brain chemistry. It is found in various foods like mushrooms, cheese, tomatoes, and broth.

• What sparked international panic and biased science about MSG?
