Two points about your list. One: hydrolyzed vegetable protein. In the past, processors could use unspecified hydrolyzed protein as an ingredient. The protein source could be casein. Under the latest FDA rules, a casein-containing ingredient must be listed as hydrolyzed milk protein or the equivalent. Hydrolyzed vegetable protein can no longer contain casein or whey. Either way, however, hydrolyzed, by definition, means broken down into constituent amino acids. It is conceivably possible but highly unlikely that they would cause reactions. After all, the safest, most non-allergenic infant formulas are made from hydrolysates. Two: lactates. Lactates are salts of various minerals. They are not proteins. They contain no milk products at all. Hope this helps, Steve Carper author of Milk Is Not for Every Body: Living with Lactose Intolerance http://ourworld.compuserve.com/homepages/stevecarper
