<<Disclaimer: Verify this information before applying it to your situation.>> Thank all those who answered my plea for an explanation of the ingredient, L-Bulgaricus used in yogurt. It turns out that L. bulgaricus is "Lactobacillus bulgaricus", a bacterium. I was told this good bacteria makes its home in the intestines and helps digestion. It is totally unrelated to Bulgar Wheat, and is therefore acceptable for a GF diet. Thanks again, Carol in NJ
