What Do Doctors Tell About This Problem?
According to Dr. Carolyn Dean, M.D., N.D., the author of The Magnesium Miracle
Why People Use Aspartame?
Aspartate and glutamate are amino acids. They act as natural neurotransmitters in the brain. The concentration of glutamate and aspartate is small — however, the same acids used as food additives. The quantities are different.
Glutamate is in MSG, powerful food additive. MSG is a flavor enhancer, found in various processed foods. Plenty of Chinese buffet places use MSG.
Aspartate is one of three components in the aspartame. It acts as the sugar substitute. Famous names are NutraSweet or Equal.
Why Are These Food Additives Dangerous?
Food additives containing glutamate and aspartate in high quantities stimulate brain cells. This prolonged stimulation overexcites cells. The constant stimulation can push brain cells to death. This process is called excitotoxity.
Conclusion
Aspartame and MSG are excitotoxins. These food additives contain amino acids, glutamate, and aspartate, which in average body’s metabolism work in tiny quantities. Significant amounts of aspartame and MSG overstimulate brain cells. It leads to undergo a process of cell death. It is called excitotoxity.
Do we need it? It is op for you to choose. There is plenty of healthy and good tasting food which could bring pleasure and benefits to our body. Why rush destroying our bodies? Let’s cherish it and avoid food additives such as aspartame and MSG.
