Thank you for taking the time to write and tell me about yourself. I find this very interesting. I completely understand the reasons and yes, it is so important to listen to your body and soul. Exactly the warmth, the inner digestive fire was one of my biggest question marks when I switched to raw food: I also studied Chinese nutrition and Ayurvedic nutrition. I then heard a wonderful answer from a raw vegan chef from Switzerland. He studied also in India...His name is Urs Hochstrasser. He is probably raw since around 1990 I guess...He said: If you take the plant as it is and don't cook it, it contains all the elements... including the fire, wood and warmth. Even if you eat it raw. I'll see how it works for me. I started with raw food as a self-experiment. I didn't set myself a goal or anything like that. I just keep going as long as it feels right and see where it takes me. Last weekend I ate roasted peanuts and they were delicious ;)
