I've told this story before, but here goes.
Visited an AK'er in Vermont several years back, he was giving me boxes of classical records for free. Yeah, a heck of a hump from Ky, but I'd never seen Vermont.
His wife is a serious gardener, and provided a small (toast size) plate of black beans she grew herself, rice, and a small chicken breast from the local farmer's market.
The wife and I ate this quality, tiny meal and
were not hungry for 12 hours.
Vitamins and minerals are what the body craves. When it doesn't get it, it tells you to eat more. Couple that with the continual slathering of "taste modifiers" and what some call "excitotoxins" and you have a perfect storm for obesity and disease.
Excitotoxins are substances, primarily food additives like MSG, aspartame, and hydrolyzed protein, that overstimulate neurons to death, causing brain damage, excitotoxicity, and neurological issues
. They work by overloading glutamate receptors, causing excessive calcium influx, leading to cellular dysfunction, memory loss, anxiety, and potential neurodegenerative diseases.
What Are Excitotoxins and How Do They Affect the Body
- Definition: Excitotoxins are compounds (often additives) that activate neurons to the point of destruction.
- Mechanism:They hyperactivate NMDA receptors (glutamate receptors), causing an excessive influx of calcium into cells
. This causes the cells to die (apoptosis)
.
- Common Sources: Monosodium glutamate (MSG), aspartame (NutraSweet), cysteine, hydrolyzed vegetable protein, and natural flavoring.
- Impact: They are linked to neurodegenerative disorders like Alzheimer's, Parkinson's, Huntington's disease, and amyotrophic lateral sclerosis (ALS).
Symptoms of Excitotoxicity (Glutamate Overload)
Symptoms often relate to nervous system dysfunction due to cell damage:
- Neurological: Agitation, anxiety, panic attacks, depression.
- Cognitive/Physical: Memory loss, sleeplessness, low energy.
- Other: Fatigue and pain, often associated with disorders like fibromyalgia.
Key Aspects of Excitotoxicity
- Cellular Excitotoxicity: A process where excessive extracellular glutamate triggers a massive calcium influx, causing neuronal cell death.
- Vulnerability: The immature nervous system (infants) is highly sensitive to these toxins. Elderly consumers are also more vulnerable.
- Management: Reducing intake of processed foods containing added monosodium glutamate (MSG) or aspartame is recommended to avoid symptoms.
