Overview and Purpose
The Cancer Prevention Diet: The Macrobiotic Approach to Preventing and Relieving Cancer by Michio Kushi and Alex Jack (2005) is a comprehensive, 612-page guide presenting a holistic dietary and lifestyle framework aimed at preventing and supporting recovery from cancer. Rooted in macrobiotic philosophy and traditional Asian medicine concepts, the book emphasizes natural prevention strategies over conventional treatment-centric approaches. It addresses the rising cancer incidence in the United States and globally, highlighting environmental and dietary factors as primary contributors to cancer risk. The authors advocate for a balanced, whole-foods-based diet combined with emotional, spiritual, and environmental harmony to reduce cancer incidence and improve outcomes.
The book is intended for cancer patients, caregivers, health practitioners interested in integrative oncology, and individuals seeking cancer prevention through diet and lifestyle. It offers detailed nutritional protocols, home care practices, emotional and spiritual guidance, and environmental recommendations. The text integrates modern medical diagnostics with traditional observational methods, aiming to empower readers with self-care tools and encourage collaboration with medical professionals and qualified macrobiotic teachers.
Part 1: Preventing Cancer Naturally
This foundational section sets the stage by contextualizing the cancer epidemic and outlining the macrobiotic approach to prevention. It critiques the limited success of the "War on Cancer," attributing ongoing high cancer rates to insufficient focus on prevention, especially nutritional and environmental factors. The authors cite that 80-90% of cancers are linked to diet and environmental exposures, yet research funding and public health efforts remain disproportionately focused on treatment.
The macrobiotic diet is presented as a holistic system emphasizing whole grains (40-60% of intake), vegetables (25-35%), beans and sea vegetables (5-10%), with occasional fish and fruits. It excludes red meat, dairy, refined sugars, and processed foods. The diet is grounded in yin-yang principles, which classify foods and cancers to guide individualized dietary therapy aimed at restoring balance. For example, "yang" cancers such as prostate and colon are associated with excess animal fats and proteins, while "yin" cancers like breast and stomach cancers relate to sugary, processed, and dairy foods.
Beyond diet, the section stresses the importance of proper food preparation, thorough chewing, eating according to hunger cues, and avoiding late-night meals to optimize digestion and toxin elimination. Seasonal and regional adaptations are encouraged to align with natural cycles. Emotional health and spiritual practices, including meditation, prayer, sound therapy, and visualization, are integral to the approach, supporting healing and stress reduction. The authors caution against aggressive "battle" imagery in cancer care, advocating instead for compassionate self-love and emotional expression.
Environmental stewardship is emphasized, with recommendations to minimize exposure to electromagnetic radiation, synthetic chemicals, and pollutants. Physical activity, stress management, and avoidance of smoking and radiation complement dietary measures. Home care techniques such as body scrubs, compresses, and natural remedies are described to support the body's healing processes.
Dietary and Lifestyle Recommendations for Specific Cancers
Bone Cancer
Bone cancer is linked to excessive animal protein, saturated fats, and refined salt. The macrobiotic diet for bone cancer focuses on whole grains, sweet and root vegetables, beans (notably black soybeans), and sea vegetables, while avoiding animal foods and sweets. Home care includes compresses and body scrubs to improve circulation and detoxification. Emotional stability and maintaining order in life are highlighted as supportive factors.
Brain Cancer
For brain cancer, the diet excludes animal products, sugar, stimulants, and processed foods. Emphasis is placed on whole grains, vegetables, beans, sea vegetables, and minimal fish consumption after initial improvement. Home care involves cooling compresses and massage to reduce inflammation. Emotional positivity and minimizing exposure to electromagnetic fields are stressed as important adjuncts.
Breast Cancer
Breast cancer is associated with dairy, animal fats, sugar, and refined foods. The recommended diet centers on whole grains such as brown rice, millet, and barley; vegetables; fermented soy products; and sea vegetables. Dairy, red meat, sweets, and processed soy are avoided. Emotional expression and social support are considered vital for recovery. Special drinks and compresses are suggested to aid healing.
Children’s Cancer
Children’s cancers are linked to prenatal and early life nutrition, with dairy, sugar, refined flour, and processed foods identified as primary contributors. The diet emphasizes brown rice combined with millet or barley, steamed vegetables, beans, and sea vegetables, initially excluding animal foods. Emotional care and environmental factors are addressed to support holistic healing.
Colon and Rectal Cancer
Colon and rectal cancers are attributed to high intake of animal fats and proteins, low dietary fiber, and sedentary lifestyles. The macrobiotic protocol eliminates animal foods initially, focusing on whole grains, vegetables, beans, sea vegetables, and fermented foods. Home care includes body scrubs and compresses to stimulate circulation and detoxification. Emotional health and maintaining a positive attitude are emphasized.
Female Reproductive Cancers
Diet plays a significant role in menstrual cycle regulation and reproductive health. Imbalanced diets contribute to irregular cycles and tumor formation. The macrobiotic diet for female reproductive cancers avoids animal foods (except occasional white fish), dairy, sugar, sweets, refined flour, stimulants, oils, and chemically processed foods. It emphasizes whole grains (40-50%), especially brown rice with millet, barley, and aduki beans; soups with sea vegetables and vegetables; steamed or boiled vegetables; beans; sea vegetables; moderate condiments and homemade pickles; and minimal fruit and nuts (except chestnuts).
Food is to be chewed thoroughly, overeating and late-night meals avoided. Special drinks and dishes tailored for ovarian, uterine, and cervical cancers include porridges and teas with daikon, lemon, kumquat, tangerine, and sea vegetables. Home care practices involve body scrubs, compresses, daikon hip baths, vegetable plasters, and massage to improve circulation and relieve pain.
Emotional and lifestyle factors emphasize fostering positive emotions supported by whole grains, beans, leafy greens, sea vegetables, and white fish, while avoiding dairy, meat, sugar, and refined products. Honest communication, moderate exercise, breathing exercises, fresh air, and avoidance of smoking, radiation, electromagnetic sources, and synthetic products are recommended. The authors caution against artificial menstrual regulation, promoting natural birth control, home birth, and breastfeeding. Personal case studies illustrate improvement or reversal of cancers through macrobiotic diet and lifestyle changes, underscoring self-responsibility.
Chapter 36: Kidney and Bladder Cancer
Kidney cancer is linked to high-fat foods combined with cold foods and beverages, while bladder cancer is characterized as more yin and kidney cancer more yang. Dietary balance differs slightly: a more yin diet is advised for kidney cancer, and a more yang diet for bladder cancer.
Medical evidence includes observations of low cancer rates in African populations before the introduction of refined foods and a 72% lower bladder cancer incidence among Seventh-Day Adventists. Fermented brown rice has been shown to reduce bladder cancer in animal studies.
Diagnosis involves urinalysis and imaging, with needle biopsy discouraged for kidney cancer. Visual signs include dark circles or bags under the eyes, ear redness or oiliness, and urine color and frequency changes.
Dietary recommendations for both cancers include avoiding dairy, animal fats, sugar, refined flour, oily and cold foods, and spices. Emphasis is placed on whole grains, soups with sea vegetables, steamed vegetables, small amounts of beans and sea vegetables, minimal animal food (occasional white fish), and minimal fruit (preferably cooked). Beverages should be warm or hot, avoiding cold drinks.
Special drinks for kidney cancer include sweet vegetable drinks, carrot-daikon drinks, shiitake-daikon tea, aduki juice, rice juice, and beet juice. For bladder cancer, recommended drinks include dried daikon and shiitake tea, hijiki with daikon and shiitake, miso-scallion condiment, ume-sho-kuzu or ume-sho-bancha for bleeding, and cabbage juice for pain relief.
Home care involves body scrubs, compresses, palm healing, and ginger compresses for urethra blockage. Emotional aspects relate to sexuality and intimacy, with positive foods including whole grains, beans, leafy greens, sea vegetables, seeds, white fish, and sea salt. Harmful foods include eggs, dairy, meat, sugar, refined foods, stimulants, and alcohol.
Lifestyle recommendations include avoiding wool and synthetic clothing, limiting electromagnetic radiation exposure, taking moderate hot baths, and maintaining a positive mindset and body warmth. A personal case study of Sheldon Rice illustrates recovery from advanced bladder cancer through strict adherence to the macrobiotic diet and shiatsu therapy.
Chapter 37: Leukemia
Leukemia is characterized by uncontrolled white blood cell production, with acute and chronic forms. Causes include overconsumption of yin foods such as sugar, sweets, dairy, tropical fruits, and refined flour, as well as chemicalized foods and radiation exposure. Diet influences susceptibility by affecting blood pH balance, with leukemia linked to excessive yin diets increasing acidity.
Medical evidence includes caloric restriction reducing leukemia incidence in mice, whole grains and salt reversing leukemia in chickens, and lower rates among Seventh-Day Adventists. Genistein in soy has been shown to kill leukemia cells, and brown rice extracts inhibit leukemic growth.
Diagnosis involves blood tests and bone marrow biopsy, with visual signs including pale lips, whitish lower eyelids, and fingernail changes.
Dietary recommendations advise avoiding extreme yin foods (sugar, sweets, dairy, tropical fruits, oily foods, chemicals) and extreme yang foods (meat, poultry, eggs, cheese). Small amounts of white fish are allowed occasionally. The diet emphasizes whole grains, soups with sea vegetables and vegetables, cooked vegetables, moderate beans and bean products, daily sea vegetables, moderate condiments, and homemade pickles.
Fruit and fruit juices are avoided until improvement; sweets are avoided, with sweet vegetables and amasake used to satisfy sweet cravings. Nuts and seeds are limited. Beverages should be warm or hot, avoiding cold drinks and grain coffee initially.
Special drinks and dishes include miso-zosui with brown rice and vegetables and brown rice with aduki beans and kombu. Thorough chewing, avoiding overeating, and not eating late at night are emphasized.
For yang-type leukemia, kombu seasoning and sweet vegetables are recommended, avoiding fish except occasional white fish; yin-type leukemia may include fish more often. Emotional and lifestyle factors align with those for kidney and bladder cancers.
Liver Cancer
Liver cancer is a leading cause of cancer deaths worldwide, including hepatomas and cholangiocarcinomas. The liver’s functions include filtering toxins, producing bile, regulating blood sugar, and manufacturing hormones, with notable regenerative capacity.
Causes include overconsumption of animal protein and fat, alcohol, sugar, refined flour, toxins, and pollutants. Saturated fats block capillaries, while unsaturated fats can form free radicals. Liver cancer often follows hepatitis, jaundice, and cirrhosis.
Medical evidence supports the benefits of sea vegetables and shiitake mushrooms in improving fat metabolism. Populations with balanced diets, such as Mormons, show lower liver cancer rates. Shoyu (soy sauce) exhibits anticarcinogenic effects.
Diagnosis involves blood tests, imaging, and biopsy. Traditional signs include liver tenderness, forehead wrinkles, and skin color changes.
Dietary recommendations exclude animal foods high in protein and fat, sugar, stimulants, alcohol, and chemical additives. Refined flour and oils are limited, and cold foods and drinks, tropical fruits, spices, coffee, and black tea are avoided.
The diet emphasizes whole grains (brown rice with millet, barley, aduki beans), miso-based soups with sea vegetables, steamed vegetables (broccoli, carrot tops, daikon, burdock, cabbage), beans, sea vegetables, moderate condiments, and pickles. Fish and animal foods are avoided, with small amounts of white fish occasionally allowed if craved. Fruit is limited, and sweets and desserts are avoided until improvement, replaced by sweet vegetables and amasake.
Beverages include bancha twig tea, with grain coffee avoided initially. Thorough chewing, avoiding overeating, and not eating late at night are stressed.
Special drinks include roasted buckwheat and scallion tea, sour tastes such as lemon juice and tart apple sauce, brown rice and barley porridge with grated daikon, and teas made from dried daikon, burdock, shiitake, and cabbage.
Home care involves body scrubs and compresses such as hato mugi-potato-cabbage plasters. Emotional considerations highlight positive emotions like patience, strength, and courage, nourished by whole grains and leafy greens, while negative emotions such as impatience, frustration, and anger are discouraged.
Lung Cancer
Lung cancer is the leading cause of cancer deaths in the U.S., with multiple histological types and a poor five-year survival rate (~16%). Smoking is the primary cause, but secondhand smoke, radon, asbestos, heavy metals, radiation, and pollution also contribute. Diet plays a protective role, with beta-carotene-rich foods reducing risk.
Medical evidence shows diets high in grains, vegetables, and fruits and low in animal fats and dairy reduce lung cancer risk. Broccoli, miso, and azuki beans are protective, while dairy and sugar-rich foods increase risk significantly.
Diagnosis includes imaging, bronchoscopy, sputum exams, and biopsies, with oriental diagnosis using facial signs and pulse.
Dietary recommendations exclude meat, poultry, eggs, dairy (especially cheese), seafood, baked flour products, sugar, sweets, fruits and juices, stimulants, alcohol, drugs, and artificial/refined foods. The diet emphasizes whole grains (brown rice with millet, barley, aduki beans), vegetables (broccoli, carrot tops, daikon, lotus root), beans, sea vegetables, and moderate condiments.
Raw foods and oils are avoided during the first month, with moderate unrefined oil introduced later. Nuts and seeds are limited except chestnuts, and sweets/snacks are avoided initially. Thorough chewing is emphasized.
Special drinks and dishes include sweet vegetable drinks, dried daikon/shiitake/lotus root tea, lotus root juice, and brown rice porridge with grated lotus root. Home care involves body scrubs, finger massage, and compresses such as mustard and lotus root plasters.
Emotional health is linked to lung function, with lungs associated with wholeness and happiness. Unhealthy lungs correlate with sadness and rigidity. Environmental recommendations include avoiding smoking, smoky environments, metallic jewelry, electromagnetic pollution, smog, chemical fumes, and asbestos, while maintaining fresh air and indoor plants.
Personal cases demonstrate improvement with a macrobiotic diet emphasizing whole grains and vegetables.
Lymphatic Cancer (Lymphoma and Hodgkin’s Disease)
Lymphatic cancers include lymphoma and Hodgkin’s disease, with two types distinguished by yin and yang characteristics: overly yin types involve inflammation and expansion, while yang types involve hardening.
Causes include excessive yin foods such as refined/artificial foods, sugar, dairy, tropical fruits and vegetables, and spices causing swollen lymph nodes, and yang factors like excessive salt and baked flour contributing to hardening.
Hodgkin’s disease involves inflamed lymph nodes and spleen, while Non-Hodgkin’s lymphoma involves malignant lymphoid tumors.
Medical evidence links high animal protein intake to lymphoma risk, while grains and vegetables reduce risk.
Diagnosis involves lymph node biopsy, bone marrow biopsy, and scans, with oriental diagnosis using lip, eyelid, skin, temple, ear, and nose color.
Dietary recommendations exclude dairy, sweets, and animal foods except occasional fish, and avoid tropical vegetables. Raw foods are avoided initially. The diet emphasizes whole grains, vegetables, sea vegetables, beans, and pickles. Thorough chewing and avoiding overeating are stressed.
Special drinks and dishes include kinpira-style burdock, carrot, and kombu; dried daikon tea; sweet vegetable drinks; and ume-kuzu drinks. Home care includes body scrubs, compresses, fasting, and limited hot baths.
Emotional aspects are acknowledged but detailed discussion is truncated in the source material.
General Themes and Strengths
The book’s major strength lies in its detailed, integrative approach combining diet, lifestyle, emotional health, and environmental factors into a coherent cancer prevention and supportive care system. It provides practical dietary guidelines tailored to specific cancer types, supported by clinical observations, case studies, and references to scientific research. The macrobiotic philosophy’s emphasis on balance, moderation, and respect for natural cycles offers a comprehensive framework beyond nutrition alone.
Its inclusion of home care techniques, emotional and spiritual practices, and environmental recommendations broadens the scope of cancer support. The integration of traditional diagnostic methods with modern medical tests offers a unique perspective for early detection and individualized care. The book encourages collaboration with medical professionals and qualified macrobiotic teachers, promoting a complementary rather than alternative stance.
Limitations and Cautions
While the book presents extensive dietary and lifestyle protocols, it is important to note that many claims are based on observational studies, case reports, and traditional knowledge rather than large-scale randomized clinical trials. The authors advocate for further clinical research to validate macrobiotic approaches.
Some recommendations, such as avoidance of certain foods or supplements, may not align with all conventional medical advice and should be considered carefully in consultation with healthcare providers. The book’s strong emphasis on yin-yang classification and traditional Asian medicine concepts may require readers to familiarize themselves with these frameworks for full comprehension.
