The Famous 42-Day Breuss Juice Diet from Austria: Origins, Recipe, and What Science Says

The concept of using food as medicine is ancient, but in the 20th century, a particular fasting regimen gained worldwide attention for its ambitious health claims: the Breuss Juice Diet. This 42-day regimen, developed by an Austrian naturopath, promises a radical cleanse focusing solely on a specific blend of vegetable juices and teas.


🇦🇹 The Origins: Rudolf Breuss and the 42-Day Fast

The diet is the brainchild of Rudolf Breuss (1899–1990), an Austrian naturopathic practitioner.

  • The Philosophy: Breuss based his diet on the belief that cancer cells can only survive on solid food protein, and if a person consumes only vegetable juices and teas for an extended period, the cancerous growth will starve, while the body’s healthy cells remain nourished.

  • The Goal: The original intent, detailed in his book, was to create a 42-day “Total Cancer Treatment” to “nourish the body but starve the cancer.”

  • The Popularity: Breuss claimed to have helped thousands of individuals with his regimen, leading to significant popularity across Europe and the rest of the world, often cited as a natural or alternative therapy for various health conditions, not just cancer.
