glútamát

Glutamate is a non-essential amino acid, meaning the human body can synthesize it. It plays a crucial role in metabolism, particularly in protein synthesis and energy production. Beyond its metabolic functions, glutamate is also the most abundant excitatory neurotransmitter in the vertebrate nervous system. In this capacity, it is vital for synaptic plasticity, learning, and memory. Glutamate receptors are found on neurons throughout the brain and spinal cord, and their activation triggers neuronal firing.

Monosodium glutamate (MSG) is a salt form of glutamic acid that is widely used as a food additive to enhance savory flavors, commonly referred to as umami. While MSG has been a subject of public debate regarding its potential health effects, scientific consensus, based on extensive research and reviews by regulatory bodies like the U.S. Food and Drug Administration (FDA), indicates that it is safe for consumption by the general population at typical levels. Some individuals may report sensitivity to MSG, experiencing symptoms such as headaches or flushing, though controlled studies have often failed to consistently link these symptoms to MSG consumption.
