Just what is hydrolyzed vegetable protein (HVP) and why should you care? According to Wikipedia, HVP is a flavor enhancer produced by boiling cereals or legumes, such as soy, corn, or wheat, in hydrochloric acid and then neutralizing the solution with sodium hydroxide. The acid hydrolyzes, or breaks down, the protein in vegetables into their component amino acids. The result is a dark coloured liquid that contains, among other vegetable based amino acids, glutamic acid. It is used in many, many processed foods. HVP also contains aspartame.
Both glutamate (found in monosodium glutamate also known as MSG) and aspartame are
excitotoxins. Excitotoxins. like glutamate and aspartame are able to cross the blood-brain barrier. The blood-brain barrier protects the brain from blood toxins. Glutamate and aspartate are amino acids that can cross the blood-brain barrier. In normal amounts, they have cause no harm to the brain and are essential. In food additives, such as HVP, these amino acids are in much higher amounts than is required and therefore become toxic. They cause neurons to become "excited" and eventually die. HVP is one of the most dangerous additives because it contains both of these excitotoxins which together are more toxic on the brain then each one is by itself.
Aspartame is an artificial sweetener found in most diet soft drinks and diet foods. One of the best things you can do for your health is to stop drinking sodas of any kind. They have no nutritional value and in either form (sugar or sugarless) ruin your health. Drink water, teas, and water diluted 100% fruit juice. Even coffee is better for you.
Most products containing MSG or aspartame are also considered genetically modified since they use soy or corn to produce. Guinea pigs feed GM corn grew large tumors. Best to just eat whole foods and stay away from this cancer causing, brain wasting food.
For those of you who have pets. HVP can be found in pet food and pet supplements. I recently purchased Potassium Citrate Chewable pills for my dogs. Potassium citrate helps reduce the risk of kidney and bladder stones which my dogs are prone to get. I purchased them online. HVP was not listed as an ingredient online but was on the ingredient list when I received them. If HVP will destroy your brain, it will destroy your pet's brains too. Be just as careful purchasing supplements and food for them as you would for yourself.
