Hubert Czerniak i Andrzej Kawka - Czy warzywa mogą zaszkodzić i należy jeść tylko mięso? Sprawdźcie!

Kawka combines this fast with a subsequent gut-healing diet. He notes that most patients are heavily carbohydrate-dependent and their mitochondria in brain cells are starved for proper fuel (animal fats). A 72-hour fast forces the body into ketosis, unlike gradual dietary keto adaptation, which can take months in a metabolically damaged person. The fast also triggers autophagy and a population shift in the microbiome. He has used this with autistic children: after 3 days of refusal and aggression, the child switches to accepting the real food offered, and their behavior improves dramatically. He emphasizes that plenty of salt water prevents the discomfort.

The protocol is designed to first clear the gut (via fasting), then provide easily absorbable nutrients that repair enterocytes. The collagen, glycine, and minerals from bones seal the tight junctions. Kawka explained that the gut is protected by a thick layer of good bacteria and mucus; when those are depleted, macromolecules leak through, causing inflammation. The bone broth provides the raw materials to rebuild that barrier. He emphasizes the scientific detail that the collagen molecule is missing glycine, which is abundant in skin, tendons, and bones — exactly what the long cooking extracts.

Kawka explains that natural milk straight from the animal contains live bacteria and enzymes that aid digestion. Pasteurization destroys these and the natural lactase enzyme, leading to lactose intolerance. By letting raw milk ferment for 5 days, the natural lactobacilli fully consume the lactose, converting it to lactic acid and creating a dense, sour probiotic. Even dead bacterial bodies serve as food for good bacteria and kill pathogens. He personally sources milk from a nearby goat farmer and Jersey cow, and recommends using small glass jars. The sour milk can be blended with ripe fruits and honey to improve taste for children, but without added sweeteners it’s already adequately sweet due to the fruit.

Kawka had been telling people that vegetables are healthy and should be eaten, even though he himself didn’t like them and ate very few. For eight years he used an iodine supplement — 32 drops daily — yet his intracellular iodine measurement (soczek) remained over 60% deficient. He then experimented with a strict carnivore diet, removing all plant foods. After just five weeks, his iodine deficit halved, and after ten weeks it was down to a mild deficiency. He attributes this to the removal of plant antinutrients (goitrogens, phytates, oxalates) that interfere with iodine transport into cells. This result convinced him that the less plants he eats, the better his mineral status.

Kawka points out that Buddhism, which promotes veganism for monks, had the least influence in Okinawa. Because of that, Okinawans traditionally ate more red meat than anywhere else in Japan. They also consumed marine animals and seaweed, which provided large amounts of iodine and minerals. The current decline in Okinawan longevity coincides with the introduction of Western market food. The 'plant-based' narrative, he argues, is a marketing creation that ignores the crucial role of animal foods in the original Okinawan diet.

Kawka explains that plants cannot run or fight, so they evolved biochemical warfare. The most protected parts are the seeds and grains, as they need to survive to reproduce. Cruciferous vegetables, for example, contain glucosinolates that can help in cancer therapy because they are toxic to cancer cells, but those same compounds can block iodine uptake in people with hypothyroidism or Hashimoto’s. He now treats all plants as 'zioka' (herbs) — substances with specific effects that can heal or harm depending on dose and constitution. This explains why some people thrive on raw salads while others develop autoimmune flares. He recommends that healthy individuals minimize plant intake, using vegetables only occasionally, and that diseased individuals use specific plants therapeutically.

Kawka explains the evolutionary strategy: trees produce fruit to attract animals that will eat the fruit and disperse the seeds in their droppings. The fruit is only ‘offered’ when the seed is mature — indicated by ripeness. Before that, the fruit contains lectins that damage the guts of would-be eaters. He references the plant defense theory: since plants can't move, they produce biochemicals. While he previously lectured that all fruits contain harmful lectins, he now understands that ripe fruit has minimal lectins. He recommends only eating fruit that is fully mature and ideally local and seasonal.
