Why People Avoid Glutamic Acid
People may avoid glutamic acid due to dietary restrictions such as veganism, since it can be derived from both plant and animal sources. Without explicit labeling of the source, it is difficult to determine if the glutamic acid is vegan-friendly. Additionally, some individuals may seek to avoid additives in general or have sensitivities to glutamates.
