<<Disclaimer: Verify this information before applying it to your situation.>> I don't see any relation between no harm & wheat starch. Have you any data to know that all people taked wheat starch? How do you know that a person take 100 grams of wheat starch per day? I think that the only way to see the minimum level of gluten (that sure depends by the person), is to make a specific test with "blind" testers.
