Immediately is the day that this longstanding oversight is lastly corrected. 😊
I credit score the Wulzen Issue as the first motive I’m nonetheless doing the identical outside actions right now that I used to be doing in my teenagers and twenties.

What’s the Wulzen Issue?
The time period “Wulzen Issue” refers back to the heat-sensitive substance identified 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 school member at Oregon State College, beginning in 1933.
By means of Dr. Wulzen’s analysis within the late Thirties and early Forties, she noticed {that a} food regimen missing sure vitamins brought about 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 food regimen.
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 food regimen of uncooked entire milk thrived, whereas these on pasteurized milk developed joint stiffness.
The distinction pointed to a crucial, heat-sensitive nutrient that was later dubbed the Wulzen Issue.
Dr. Wulzen and Dr. Worth
You might have seen from the timeframes of Dr. Wulzen’s analysis described above that she was a recent 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 general 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 corresponding 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 concerning the advantages of consuming uncooked, unprocessed animal fat.
What Meals Include 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 could be essentially the most accessible meals to incorporate within the food regimen 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 exams on uncooked butter that had been frozen for a 12 months. 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 nicely.
Analysis found that this substance might 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 essential to acquire uncooked, grassfed dairy for your loved ones’s food regimen is nicely value it!
The Wulzen Issue is among the greatest, however curiously, least identified advantages of consuming this extremely revered conventional meals.
