<<Disclaimer: Verify this information before applying it to your situation.>> Hello! I received an e-mail to one of my posts regarding olive oil and its gluten-free, casein free status from Lucia Crosson at Omega Nutrition. If anyone would be interested in this post, I will e-mail it too you. I thought that her information was helpful, since my husband has multiple sensitivities. She indicates that olive oil is gluten-free and lactose & casein free. Kristen S. White Marbledale, CT
