I did a quick search and I agree zinc would be beneficial. However, I am going to suggest some foods which will probably sound counter intutiative to you, given what your DD is going through, but this is what I would feed my child if I were in the same position as you.
Raw cows milk, raw cream (if you can get it), raw eggs with a little raw unheated
honey. I would also give her a little raw veggie juice (60% celery, 20% zucchini, 10% parsley and 10% cilantro) once a week. Immediately after giving the juice I would give my child some raw cream or raw butter because fats must be present with the juice to make sure the heavy metals pulled from the body from drinking the juice do not cause harm or stay in the body.
I would also give her a half tsp of high vitamin butter oil
with the omega 3 oils you are giving her. I don't what form your are giving her but if she were mine I would be giving her cod liver oil.
Okay, now why would I suggest these things, well first I would recommend reading this article from Dr Mercola's website on Autism and malnutrition, I understand your DD has been dx with Autism but as she is vaccine damaged and is obvioulsy malnurished from her condition I think it would be a useful article to read. Read the articles linked at the end of the article too.http://www.mercola.com/2004/jun/26/a...lnutrition.htm
Here's how I would serve the milkshake (2 servings):
2 ounces of raw milk
2 onces of raw cream (if you can't get raw cream, use 4 ounces of milk and don't shake it so you get the cream from the top.
1 raw egg
1/4 teaspoon unheated
Blend all the ingredients together for 5 seconds.
Before someone jumps on me about honey and infants I would like to add this:Unheated
honey contains an insulin-like substance that is produced by bees when collecting nectar. At temperatures over 93º F the insuline-like substance begins to detrimentally alter and is destroyed at 100º F. Unheated honey is fine for infants if fed small amounts at a time. Honey heated above 104º F may cause toxicity in infants.
I would also try kefir made with raw milk/cream.
