I have had digestion problems. It could be a spleen problem. Julia Chang suggested that I follow the weak spleen program. No raw foods...no cold foods, no citrus, no bananas, no tomatoes and no cold drinks. It worked. I now take no enzymes. don;t belch,don't burp, and when I do eat a salad if I crave one... I burp and belch. But I pretty much follow the program. If I need the goodies from raw food I juice.
