Factors Favorable and Unfavorable to Cancer

By Dr. Royal Lee

Summary: In this brief but poignant passage, Dr. Royal Lee observes that cancer tends to develop only in people with a weakened or imbalanced endocrine system. Healthy thyroid function in particular, he says, is critical in defending against the disease. This includes optimizing the effect of the gland’s hormone thyroxine by ensuring adequate levels of vitamin F, a complex of fatty acids that was recognized in the early days of nutrition as an essential nutrient in food but is inexplicably unacknowledged today. While vitamin F works synergistically with thyroxine to help prevent cancer, Dr. Lee says, one substance that should be avoided is anterior pituitary growth hormone, or “human growth hormone” (HGH). This compound, popular among bodybuilders and athletes today for its performance enhancement, is a “most potent stimulator of cancer,” he warns, and any product that might contain it should be categorically avoided in treatment of the illness.

Acidophilus Yeast

By Dr. Royal Lee

Summary: In this primer on the benefits of lactic acid to digestion, Dr. Royal Lee explains the science behind his remarkable bowel-normalizing product Acidophilus Yeast (known today as Lactic Acid Yeast), which has the special distinction of being able to convert any dietary carbohydrate into lactic acid within the colon. Not only does this action acidify the bowel, thus killing potentially dangerous microorganisms and promoting balanced gut flora, but the yeast also releases enzymes that aid digestion, and it provides bulk to stool—all of which help ensure proper bowel function. Dr. Lee backs up his comments by presenting a clinical study showing Acidophilus Yeast’s impressive results in combating constipation, the researchers stating unequivocally the chief reason for the yeast’s effectiveness: “It has been demonstrated time and time again that the stools of patients who are constipated are, in a very large majority, alkaline…The lactic acid acts as a stabilizer of the hydrogen ion concentration in the colon.” With many alternative health practitioners today promoting indiscriminate alkalization of the body, the words of these investigators are well worth remembering.

Guanidine, Cider Vinegar, and Health

By Dr. Royal Lee

Summary: Dr. Royal Lee lauds Vermont physician Dr. D.C. Jarvis, author of the classic book on holistic health Folk Medicine. In particular, Lee praises Jarvis’s recommendation of apple cider vinegar as a natural remedy for a host of disorders, from guanidine toxicity as a result of the overconsumption of meat to a dysbiotic gut to constipation to low thyroid to overweight. (Two teaspoons of cider vinegar in a glass of water at each meal dependably effected gradual weight loss, Dr. Jarvis observed.) Dr. Lee discussing Dr. Jarvis is a must for any fan of nutrition, history, or both.

The Effects of Vitamin Deficient Diets on Rats, with Special Reference to the Motor Functions of the Intestinal Tract In Vivo and In Vitro

By Louis Gross

Summary: Historically significant British study from 1924 on the pathological lesions appearing in the nervous system and digestive tract of rats fed vitamin deficient diets. This article demonstrates the seriousness and excellence of early vitamin research. From The Journal of Pathology and Bacteriology, 1924. Lee Foundation for Nutritional Research reprint 24.

Studies of a New Type of 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 and known today as Lactic Acid Yeast—that converts 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, Lactic Acid Yeast is 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. Clinical Osteopathy, 1940.

The Use of Raw Potatoes

By Dr. Royal Lee

Summary: Dr. Lee discusses the nutritional value of potatoes, explaining that much of that value is lost when they are cooked. “We may estimate that 25 percent of the vitamins are lost in cooking either by heat or leaching. The loss of vitamin C is particularly fast….” In addition, he says, “the cooked potato contains no enzymes, as all enzymes are destroyed by heat.” One such enzyme, studies showed, helps relieve constipation, while others are even more precious. “One of the enzymes found in raw potatoes is phosphatase, which promotes assimilation of calcium and iron in particular; another is tyrosinase, an essential component of the vitamin C complex and associated directly with the function of the adrenal glands.” (Dr. Lee often referred to raw potatoes and raw mushrooms as the best food sources of tyrosinase available.) Lee gives tips on conserving potatoes’ nutrients when cooking them and instructs readers to be sure to add lemon juice to freshly extracted potato juice, which keeps the juice from oxidizing and turning black.

Protective Colloids Found in Ancient Remedies

By Dr. Royal Lee

Summary: The word hydrophilic means water loving, and in this 1958 article, Dr. Royal Lee discusses the digestive benefits of substances known as hydrophilic colloids, which are found in foods such as apples and okra but also in nonnutritive materials such as clay. In the gastrointestinal tract, these compounds draw up liquid, creating bulk that initiates peristalsis and fosters bowel regularity. At the same time, they also soak up irritants, making hydrophilic colloids uniquely effective against both diarrhea and constipation. The modern use of nonnutritive hydrophilic colloids such as kaolin and bentonite to ameliorate digestive woes affirms the wisdom of ancestral cultures that used similar clays to combat dysentery and food infections, says Dr. Lee, a claim he supports with the following remarkable quote by Dr. Weston A. Price, from Price’s his classic 1939 text on traditional human diets and health, Nutrition and Physical Degeneration: “Among the groups (natives) in the Andes, Central Africa, and Australia…each knapsack contained a ball of clay, a little of which was dissolved in water. Into this they dipped their morsel of food while eating. Their explanation was to prevent ‘sick stomach’.” While modern science has elucidated much when it comes to food and health, it is important to remember that eons of human trial and error have much to teach us about nutrition as well. From Let’s Live magazine, 1958.
