Look, I'm just the messenger here. Someone mentioned Dr. Freedlander's talk about diet and Pca, so I decided to listen to it and summarize his main points for you. No one mentioned taking away your beloved coffee, green tea or alcohol. I have a small expresso machine and love to drink Nespresso coffee laced in with coconut milk; I also drink matcha green tea, as well as other teas. Sorry, I stopped drinking in graduate school, so I can't join you there. I suggest you watch the documentary "What the Health" on Netflix for an entirely different spin on which diet is best for you.
