A close reading of a list of classic McDonald's recipes from the '50s through the '70s reveals a disturbing amount of Monosodium Glutamate (MSG), a chemical whose potential health effects have caused considerable controversy.
However, the use of MSG in McDonald's food is not solely a matter of history. MSG is still present in some forms in many modern McDonald's products, including their Grilled Chicken Filet, Sausage Patty, and French Fries.
Many other foods on their menu, especially those that contain "natural flavors" or "hydrolyzed protein" as ingredients, also contain MSG. Most of the MSG is in the form of glutamic acid, the chemical's active component.Studies have indicated that MSG can cause severe allergies and even brain damage. Most baby food companies have voluntarily stopped using MSG in their products.
Glutamic acid (MSG) is a major component of McDonald's food. While there's simply no excuse for consuming their French fries or diet soft drinks, one could make a logical argument to have their hamburgers, as long as you are not a carb type.
But this does not take into consideration the MSG added to their foods. MSG is a toxic substance people consume in processed foods, and probably wouldn't if they knew it causes many of their brain cells to die.
McDonald's and most all other fast food restaurants use MSG to help sell their foods. MSG is very inexpensive and makes the food taste good -- which in many ways is similar to sugar -- but MSG is far more toxic than sugar.
MSG, like L-cysteine and aspartame, are excitotoxins, chemical transmitters that allow brain cells to communicate, as described in Dr. Russell's Blaylock's book, Excitotoxins: The Taste That Kills. Excitotoxins are exactly what they sound like: Toxins like MSG that excite your brain cells to DEATH!
The bottom line is that you are going to need to invest some time in the kitchen if you want to stay healthy and avoid fast foods, which if consumed regularly will accelerate your departure from this planet.
