Acidophilus Yeast vs. Acidophilus Bacilli
By Dr. Royal Lee
Summary: In this primer, Dr. Lee explains the science behind his bowel-normalizing product Acidophilus Yeast (known today as Lactic Acid Yeast). This special “mycelium type yeast” converts any dietary carbohydrate into lactic acid within the colon. This not only acidifies the bowel—thus killing potentially dangerous microorganisms that thrive in a more alkaline environment—but also releases enzymes that aid in digestion and provides bulk to stool, all of which help ensure normal bowel movement. “It has been demonstrated time and time again,” Lee writes, “that the stools of patients who are constipated are, in a very large majority, alakin[e]…The lactic acid acts as a stabilizer of the hydrogen ion concentration in the colon.” Circa 1940.
Facts About Sauerkraut and How to Make It
By Dr. Royal Lee
Summary: Once an important "probiotic" condiment, raw sauerkraut—a lacto-fermented food—vanished with the high-heat methods of modern food processing. Unfortunately, cooked cabbage of any kind is of little nutritional value, Dr. Lee says, and it is intolerable to people with senstive gastrointestinal tracts. Lee not only explains the value of this nutritious food but provides a fantastically simple method for preparing it. Reprint 38C, 1955.
Lactic Acid Forming Yeast in Chronic Constipation
By Chester H. Lyon and James P. Hart
Summary: Perhaps the first published study of a probiotic supplement for the treatment of constipation and related bowel disorders. The researchers fed their subjects a special mycelium-type of yeast—developed by Dr. Royal Lee—that converts all carbohydrate foods into lactic acid in the colon. (The normal pH of the colon is acidic; this promotes the growth of beneficial bacteria and inhibits the growth of harmful bacteria.) Unlike lactobacillus-type bacteria, which can convert only lactose into lactic acid, the special yeast used in the study was able to convert any carbohydrate source into lactic acid. This efficient conversion restored the lower bowel to its normal pH and function and provided improvement in every parameter that was studied. Published originally in the journal Clinical Osteopathy under the title "Studies of a New Type of Yeast In Chronic Constipation." 1940.
