Sturve bacteria to death. And where, in bowels (!?) What an increadible idea ! By using this diet you practically illiminate any iron containing food from your menu. So if you have digestive deasese and most likely, already having difficulties absorbing Vitamin B complex and iron - you are on the way to killing yourself. After being on SCD for 7 months and becoming progressively weak and pale, I've had a routine blood test done, which came up with Hematocrite of 23 (!) At that point my physycian was insisting on blood transfusion, but I was lucky to get out of the situation with just Iron pills.
