Ewa Dąbrowska
After being cleansed of toxins, the body is said to activate its self-healing mechanisms.
„Seeing the surprising effects this method produced, she understood what a remarkable phenomenon the human body is: after being cleansed of toxins, it activates its self-healing mechanisms. She devoted the following years of her professional work to this subject, culminating in the development of the Dr. Ewa Dąbrowska® diet and the establishment in 2018 of”Widząc zaskakujące efekty, jakie przynosiła ta metoda, zrozumiała, jak wielkim fenomenem jest ludzki organizm, który po oczyszczeniu z toksyn uruchamia samoleczące mechanizmy. Dalsze lata swojej pracy zawodowej poświęciła temu zagadnieniu, co zostało uwieńczone opracowaniem diety dr Ewy Dąbrowskiej® i powołaniem w 2018 r.

Fasting is said to cleanse the body of toxins and activate its self-healing mechanisms.
„Seeing the surprising effects, she understood that our health depends largely on our lifestyle—that is, mainly on what we eat and how much we move—and that fasting, by cleansing us of toxins, activates our self-healing mechanisms. She devoted the following years of her professional work to spreading this truth. This culminated in the development of the Dr. Ewa Dąbrowska® diet, putting her experiences into publications, and establishing the Dr. Ewa Dąbrowska Health Promotion Institute in 2018.”Widząc zaskakujące efekty, zrozumiała, że nasze zdrowie w głównej mierze zależy od stylu życia, czyli głównie od tego, co jemy i jak się ruszamy i że post oczyszczając nas z toksyn, uruchamia samoleczące mechanizmy. Dalsze lata swojej pracy zawodowej poświęciła upowszechnianiu tej prawdy, co zostało uwieńczone opracowaniem diety dr Ewy Dąbrowskiej®, przelaniem na papier doświadczeń w formie publikacji oraz powołaniem w 2018 roku Instytutu Promocji Zdrowia dr Ewy Dąbrowskiej.

Short, periodic fasts are said to help remove toxins and restore the body’s balance.
„Even short, periodic fasts help cleanse the body of toxins, provide bioactive plant compounds and trace elements, and restore the body’s physiological balance. Practiced regularly, fasting may prevent many chronic diseases.”Nawet krótkie, okresowe posty pomagają oczyszczać organizm z toksyn, dostarczać bioaktywnych związków roślinnych i mikroelementów, a także przywracać fizjologiczną równowagę organizmu. Regularnie praktykowany post może zapobiegać wielu chorobom przewlekłym.

Short-term symptoms may occur at the beginning of the treatment. Ewa Dąbrowska links them to toxins being released from tissues into the blood.
„At the beginning of the treatment, as the body is detoxified, short-lived “healing crises” may occur, such as weakness, headaches, nausea, diarrhea, a slight fever, and so on. These are said to reflect the release of toxins from tissues into the blood. Similar symptoms can also be seen after using other natural methods of cleansing the body of toxins, for example”Na początku kuracji, w miarę odtruwania organizmu, mogą pojawić się krótkotrwałe „kryzysy” ozdrowieńcze np. osłabienie, bóle głowy, nudności, biegunka, stany podgorączkowe itp., jako wyraz uwolnienia toksyn z tkanek do krwi . Podobne objawy można obserwować także po zastosowaniu innych naturalnych metod oczyszczania organizmu z toksyn np.

After the short-lived crises, Ewa Dąbrowska describes a gradual improvement in well-being and diseases subsiding.
„After the short-lived crises, a gradual improvement in well-being and diseases subsiding are observed. If headaches or other symptoms occur, the intestines can be cleansed (with an enema), as the body then gets rid of large amounts of toxins and health improves quickly.”Po krótkotrwałych kryzysach obserwuje się stopniową poprawę samopoczucia i ustępowanie chorób. W razie pojawienia się bólów głowy, czy innych dolegliwości – można wykonać oczyszczenie jelit (lewatywa), gdyż wówczas organizm pozbywa się dużych ilości toksyn i następuje szybka poprawa stanu zdrowia.

Calorie restriction and fasting are said to activate the cells’ cleansing mechanisms and support repair processes.
„In her book “How to Support Cancer Treatment with Fasting,” Dr. Ewa Dąbrowska draws on current scientific knowledge and many years of clinical experience to:
explain how a cancer cell differs from a healthy cell and why its altered metabolism may matter in the development of disease,
show links between excess glucose and insulin, obesity, chronic inflammation, and the development of cancer,
explain how calorie restriction and fasting may quiet cell-growth signals (insulin, IGF-1, and the mTOR pathway), activate cellular cleansing mechanisms (autophagy), and support the body’s repair processes,,
describe the role of the immune system—our “internal doctor”—in recognizing and eliminating abnormal cells,
discuss how fasting and appropriately selected foods may support the body during cancer treatment without replacing treatment provided by an oncologist,
outline modern cancer treatments—from surgery, chemotherapy, and radiation therapy to immunotherapy, targeted therapies, and modern approaches that use the immune system,”Dr Ewa Dąbrowska, opierając się na aktualnej wiedzy naukowej oraz wieloletnich doświadczeniach klinicznych, w książce „Jak wspomóc postem terapię nowotworów”:
wyjaśnia, czym komórka nowotworowa różni się od zdrowej i dlaczego jej zmieniony metabolizm może mieć znaczenie dla rozwoju choroby,
pokazuje związki między nadmiarem glukozy i insuliny, otyłością, przewlekłym stanem zapalnym i rozwojem nowotworów,
tłumaczy, jak ograniczenie kaloryczne i post mogą wyciszać sygnały wzrostu komórek (insulinę, IGF-1 i szlak mTOR), uruchamiać komórkowe mechanizmy oczyszczania (autofagię) oraz wspierać procesy naprawcze organizmu,,
przedstawia rolę układu odpornościowego – naszego „wewnętrznego lekarza” – w rozpoznawaniu i eliminowaniu nieprawidłowych komórek,
omawia, w jaki sposób post i odpowiednio dobrane żywienie mogą wspierać organizm podczas terapii onkologicznej, nie zastępując leczenia prowadzonego przez onkologa,
przybliża współczesne metody leczenia nowotworów – od chirurgii, chemioterapii i radioterapii po immunoterapię, terapie celowane i nowoczesne metody wykorzystujące układ odpornościowy,

Fiber in plant foods is said to help remove toxins and other waste from the body.
„These foods have common features:
they are living (able to grow and produce seeds),
they provide all the nutrients needed for life, such as proteins, carbohydrates, fats, vitamins, trace elements, enzymes, and bioactive substances, often with medicinal properties (anti-cancer, anti-inflammatory, or able to normalize blood pressure or blood sugar levels),
the fiber they contain helps cleanse the body of waste substances (toxins, cholesterol, bacteria, and heavy metals),
they provide nourishment for Acidophilus bacteria, which produce vitamins, especially B vitamins, including vitamin B12, as well as substances that protect the intestine against cancer.”Pokarmy te posiadają wspólne cechy:
są żywe (zdolne do wzrostu i wydawania nasion),
są źródłem wszystkich potrzebnych do życia składników pokarmowych takich jak białka, węglowodany, tłuszcze, witaminy, mikroelementy, enzymy, a także substancji bioaktywnych, często o właściwościach leczniczych (przeciwrakowych, przeciwzapalnych, normalizujących ciśnienie, czy poziom cukru we krwi),
dzięki obecności błonnika zapewniają oczyszczanie organizmu z substancji odpadowych (toksyn, cholesterolu, bakterii, metali ciężkich),
stanowią pożywkę dla bakterii Acidophilus syntetyzujących witaminy zwłaszcza z grupy B, w tym również witaminę B12, jak i czynników chroniących jelito przed rakiem.

The review suggests that fasting may trigger adaptive redox responses, although its effects on antioxidant mechanisms depend on the protocol and the group studied.
Aim of the study: The ever-increasing disparity between lifespan and healthspan represents a challenging global issue, with metabolic dysregulation playing a central role in the initiation and progression of chronic non-communicable diseases (NCDs). This review highlights the importance of maintaining optimal redox homeostasis, with particular emphasis on reduced glutathione (GSH), for preserving metabolic health during aging.
Results: Fasting may promote adaptive redox responses by inducing mild oxidative stress and activating the same molecular mechanism, although the effects on GSH-related antioxidant mechanisms remain heterogeneous across fasting protocols and study populations. Altogether, the available clinical evidence suggests that these nutritional and lifestyle interventions exhibit more consistent beneficial effects in individuals characterized by increased oxidative burden and underlying metabolic dysfunction. Interindividual differences in GSH responses further underscore the need for targeted, tailor-made approaches that account for genetic, epigenetic, and lifestyle factors. Collectively, targeting GSH homeostasis through nutritional and lifestyle interventions represents a promising strategy for improving metabolic health and may further contribute to healthy aging, positioning redox biology at the forefront of aging research and NCD prevention.

„Metabolic Reset: Ketogenic Diet & Fasting Modern chronic disease is often driven by insulin resistance, mitochondrial dysfunction, and chronic inflammation. A well-formulated low-carb or ketogenic diet, paired with intermittent or prolonged fasting, helps restore metabolic flexibility, reduce inflammation, and enhance autophagy and mitochondrial repair. Minimizing ultra-processed foods-including industrial seed oils-is critical to reducing inflammation and metabolic damage. Key Tools: Carnivore or ketogenic diet, time-restricted eating, prolonged fasting (2-7 days/month), minimizing ultra-processed foods (including seed oils). 3.”Metabolic Reset: Ketogenic Diet & Fasting Modern chronic disease is often driven by insulin resistance, mitochondrial dysfunction, and chronic inflammation.

„Environmental pollutants increase the need for nutrients The need for efficient detoxification and excretion is greatly increased by environmental pollution from the chemical industry, herbicides and pesticides used by industrial agriculture, antibiotic treatment of animals, transport, and plastic packaging. [29] In our polluted world, the increased toxic load may be compensated for by an increase in nutrients to promote detoxification. One can respond by taking large doses of supplements of essential nutrients, for example, antioxidants vitamin C and E, and an adequate dose of selenium, which help the body detoxify harmful chemicals.”Environmental pollutants increase the need for nutrients The need for efficient detoxification and excretion is greatly increased by environmental pollution from the chemical industry, herbicides and pesticides used by industrial agriculture, antibiotic treatment of animals, transport, and plastic packaging.
