Did the discovery of fire actually ruin human health?
We are taught that cooking food was humanity’s greatest evolutionary leap. But in Return to Nature!, Adolf Just points to the ancient myth of Prometheus—who stole fire from the gods and was chained to a rock to have his liver eaten by vultures—as a profound allegory. Fire is the origin of anti-naturalism, disease, and the “fall of man.”
Just argues that the human digestive tract is not designed for dead, cooked, or heavily seasoned food. It is designed for living, raw food that you can eat exactly as it grows on the tree or vine.
Here is the deep, hidden truth about why modern diets (even “healthy” ones) are failing you, and how returning to Nature’s raw menu can restore your body and soul.
The “Curse” of the Kitchen & The Cinderella Metaphor
Just asks us to look at the consequences of fire. Without fire, we could not cook meat, brew alcohol, or create artificial medicines. But fire also chained humanity to the stove.
Just compares the modern woman to Cinderella, enslaved by the smoky, poisonous kitchen. He writes that the cooking stove is the source of “poisonous vapors” that ruin women’s health, drain their vitality, and strip them of their original, natural beauty. By abandoning the raw, sun-ripened foods of the earth, humanity traded the effortless abundance of the garden for the exhausting, disease-creating labor of the kitchen.
The “Healthy” Vegetarian Trap & The Animal Proof
Just was highly critical of both the standard meat-eating diet and the modern vegetarian diet. Why? Because modern vegetarians rely on cooked grains, boiled potatoes, and baked bread. Just wrote: “Cooked foods are dead and insipid… The unnatural cooked foods oppress our intestines; they make us languid, dull, and tired of life.”
The Proof is in the Animals: Just observed that when animals are fed cooked food or fully ripe, dried grains instead of their natural raw forage, they become “stout and fat, ugly, languid and lazy,” and eventually grow “stiff in the joints.”
- A wild horse or zebra eating raw grass is fleet, enduring, and beautiful.
- A stable-fed horse eating cooked/ripe grains is sickly, stiff, and vicious. If cooked, starchy foods make our closest mammalian relatives sick and stiff, how can they possibly build a vibrant human body?
🧂🍷 The Pipeline to Poison: Spices and Alcohol
Cooked food doesn’t just deaden the life-force; it creates a dangerous domino effect in the body. Because cooked vegetables, grains, and potatoes are naturally bland and “insipid,” civilization felt forced to add salt and spices to make them palatable.
Just warns that salt and spices are “very deleterious to health” and directly responsible for stimulating the digestive organs to crave stronger, more exciting poisons. This unnatural thirst opens the door to the “demon” of alcohol, coffee, and tea. You cannot separate the modern epidemics of alcoholism and nervous exhaustion from the cooked, heavily seasoned diet that created the craving for them in the first place.
🐍 The “Original Sin” Was a Meat Diet
Perhaps the most shocking revelation in Return to Nature! is Just’s interpretation of the Bible. He argues that the “Tree of the Knowledge of Good and Evil” was not a literal tree, but a linguistic metaphor for the animal kingdom (creatures that have the “knowledge” of good and evil, unlike plants).
Therefore, the “Fall of Man” and the original sin was the eating of meat and the hunting of animals.
- Meat-eating brutalizes the soul, instilling a “murderous passion” and bloodthirsty cravings.
- It creates “foreign matter” that ferments in the gut, generating internal heat, disease, and “sensual lusts.”
- By returning to a raw, plant-based diet, we do not just heal the body; we restore the “image of God,” replacing brutality, hatred, and vice with gentleness, peace, and pure love.
Nature’s Schedule: Fasting and the Evening Feast
Nature doesn’t just dictate what we eat, but when we eat. Just observed that in the wild, animals feed chiefly in the evening. Beasts of prey hunt at night. The stomach is most active when the sun goes down.
- Fast Until Noon: Just strongly advocates for fasting until noon, noting that his patients experienced the most miraculous healing crises when they gave their digestive organs a complete rest in the morning.
- The Evening Feast: The main meal should be eaten in the evening, mirroring the natural rhythms of the forest.
- Eat it Raw and Even Unripe: Animals instinctively prefer unripe or half-ripe fruits and grasses because they contain the most vital, stimulating life-force. Don’t fear the tart, unripe apple or the green berry; they are nature’s most potent medicine!
✨ The Takeaway
Step away from the stove. The more you cook, process, and season your food, the more you deaden its life-force and burden your body with fermenting “foreign matter.”
Nature’s true menu requires no culinary art, no salt, and no fire. It requires only the pure, sun-ripened gifts of the earth: living raw fruits, forest berries, and the vital, natural fats of raw nuts. Fuel your body with living food, and watch your physical vitality and spiritual peace soar. 🌰🍇🍏
