What’s the Wulzen Issue?
The time period “Wulzen Issue” refers back to the heat-sensitive substance recognized chemically as stigmasterol.
This fat-soluble vitamin regulates phosphorous metabolism within the physique.
It was recognized by researcher Dr. Rosalind Wulzen, who earned her doctorate in physiology and zoology from the College of California, Berkeley in 1912. (1)
Identification of the Wulzen Issue emerged from experiments with guinea pigs throughout Dr. Wulzen’s tenure as a college member at Oregon State College, beginning in 1933.
By way of Dr. Wulzen’s analysis within the late Nineteen Thirties and early Forties, she noticed {that a} weight-reduction plan missing sure vitamins brought on wrist stiffness and calcification. (2, 3)
The lacking nutrient was later recognized as plentifully current in uncooked milk and cream.
Most significantly, Dr. Wulzen additionally discovered that this joint stiffness and calcification may very well be reversed by including uncooked dairy again into the weight-reduction plan.
She documented this discovering within the paper titled “Results of Milk Diets on Guinea Pigs,” revealed within the American Journal of Physiology, that she co-authored with A.M. Bahrs. (4)
The paper particulars how guinea pigs on a weight-reduction plan of uncooked complete milk thrived, whereas these on pasteurized milk developed joint stiffness.
The distinction pointed to a vital, heat-sensitive nutrient that was later dubbed the Wulzen Issue.
Dr. Wulzen and Dr. Worth
You will have observed from the timeframes of Dr. Wulzen’s analysis described above that she was a up to date of Dr. Weston A Worth, creator of the guide Diet and Bodily Degeneration.
Printed in 1939, Diet and Bodily Degeneration focuses on Dr. Worth’s observations of 14 distinct conventional cultures from around the globe and the influence of their indigenous diets on dental and total well being.
He emphasised the significance of fat-soluble nutritional vitamins, significantly A, D and what he known as “Activator X,” later recognized as vitamin K2. (5)
These nutritional vitamins are present in nutrient-dense meals equivalent to butterfat, organ meats, egg yolks, and fish eggs.
In his guide, Dr. Worth extensively discusses the dietary superiority of uncooked, unprocessed animal meals, particularly uncooked dairy from grass-fed animals.
Thus, whereas Dr. Weston A. Worth didn’t particularly point out the “Wulzen Issue” in his writings that I’ve come throughout, the ideas he explored in Diet and Bodily Degeneration share a particular kinship of meals philosophy with the Wulzen Issue’s implications relating to the advantages of consuming uncooked, unprocessed animal fat.
What Meals Comprise Stigmasterol
Stigmasterol is present in therapeutic quantities in uncooked animal meals.
Particularly, uncooked butterfat (uncooked milk, uncooked cream, and uncooked butter) and uncooked egg yolks can be probably the most accessible meals to incorporate within the weight-reduction plan frequently to acquire healing quantities.
Uncooked butter oil would additionally include the Wulzen Think about concentrated quantities, whereas ghee (heated butter oil) wouldn’t.
The essential factor to notice is that the Wulzen Issue is destroyed by pasteurization, even low-temp, “vat pasteurized” heating strategies.
Nevertheless, freezing uncooked milk, cream, and butter doesn’t seem to hurt stigmasterol.
As proof of this, Dr. Worth wrote about his checks on uncooked butter that had been frozen for a yr. He found that there was no degradation of the fat-soluble nutritional vitamins after that time period. (6)
Different Well being Advantages from The Wulzen Issue
Whereas the Wulzen Issue is most well-known because the “anti-stiffness” issue for sustaining versatile joints freed from calcification, there are different profound advantages from consuming uncooked animal fat to acquire it as properly.
Analysis found that this substance may additionally function safety towards hardening of the arteries, cataracts, and calcification of the pineal gland. (7-9)
Thus, the time, expense, and generally appreciable inconvenience vital to acquire uncooked, grassfed dairy for your loved ones’s weight-reduction plan is properly value it!
The Wulzen Issue is likely one of the greatest, however apparently, least recognized advantages of consuming this extremely revered conventional meals.
