Neither chicken essence nor monosodium glutamate is carcinogenic. Chicken essence is based on monosodium glutamate (MSG) with other flavoring substances added for blending, and like MSG, most of its main ingredients are monosodium glutamate, which are not carcinogenic. However, excessive use of monosodium glutamate is also harmful. The daily intake of monosodium glutamate for adults should not exceed 6g, because frequent intake of excessive sodium salt will induce high blood pressure and increase the burden on the kidneys, etc. On the other hand, chicken essence is specially added with other flavoring substances. On the other hand, the nucleotides specially added in chicken essence will decompose into uric acid in the human body, so patients with high uric acid are also not suitable for consuming chicken essence. It is recommended to use chicken essence and monosodium glutamate (MSG) reasonably in daily life and not to listen to rumors. People with high risk factors for cancer are advised to have regular medical checkups to avoid delays.
