Accent seasoning, also known as Monosodium Glutamate or MSG, looks much like regular table salt. The additive, used primarily in Asian dishes to enhance the flavor, is not used often in the United States because of its allergic reactions.

While studies are ongoing, Accent seasoning has shown it affects nerve impulse transmitters within the brain and could be linked to certain diseases, including Alzheimer's. The controversy surrounding the seasoning has led to certain restaurants displaying notices to customers that their food does not contain MSG.

Although controversial, some people use the seasoning sparingly in their dishes. Sprinkled onto sauteed vegetables and as a seasoning rubbed into meats, Accent adds a spicy, tangy flavor.
