Love you, Dr. Li! You've changed my life. I don't put anything in my mouth that does not fight disease. I have no inflammation and a healthy body. Most people think I eat like a crazy person, but I've learned to love organic veggies, fruits, nuts, and legumes. No sugar, but my coffee and tea always has organic cacoa, cinnamon, and soy milk. Have different teas, honey occasionally and sprouted grains, barley, occasionally brown rice. I look younger and feel better at 63. Thank you for changing my life. I have a big family and have a lot to live for! The 5 body mechanisms of defense are crucial to learning. Not I'm going to add Earl Grey. God bless you and your family!
