Is Hydrolyzed vegetable protein (HVP) Safe for Multiple Sclerosis (MS)?

Status for MS
Why this rating?
A plant protein broken down with acid to intensify flavour. The process naturally produces free glutamates, which some people with sensitive digestion associate with symptoms.
People who are sensitive to this ingredient may notice gi. Individual responses vary, so this symptom category does not replace the condition-specific rating above.
Editorial summary
This summary is editorial and is not part of the clinical review. Ratings above are unchanged.
What HVP is
Hydrolyzed vegetable protein is made by breaking down a plant protein, often from soy, corn or wheat, into its component amino acids. It is used as a savory flavor enhancer in soups, broths, snack seasonings, sauces and processed meats.
Glutamate and the MSG question
The process frees glutamate, the same amino acid found in added MSG. The FDA explains that ingredients that naturally contain free glutamate, including hydrolyzed vegetable protein, autolyzed yeast, yeast extract and soy extracts, must be listed on the ingredient panel, but the label does not have to say that they contain glutamate. Foods made with them cannot claim No MSG or No added MSG. The FDA considers added MSG generally recognized as safe and notes that studies have not consistently triggered reactions in people who say they are sensitive, which is why our rating rests on individual tolerance.
Gluten and allergens
Because HVP can be made from wheat, soy or corn, the source matters for people who avoid those foods. Wheat and soy must be declared on a U.S. label, and a hydrolyzed wheat protein cannot be used in a food labeled gluten-free unless the finished food contains less than 20 parts per million of gluten. For inflammatory bowel disease, the NIDDK says no specific food has been proven to cause symptoms, so use a food diary with your doctor to find out whether highly seasoned processed foods bother you.
