NOTE: This information is not designed to make you feel guilty, upset or ashamed if you have or have had breast cancer. It is actually the opposite. It is designed to show you how much power over breast cancer you have regardless of your health status.
More meat = higher cancer risk
It is interesting that NZ women now eat 4x more meat than they did in the 1960s, consuming 300g per day. Breast cancer rates are now 3-4x higher than they were in the 1960s. In 1978 your risk of breast cancer was 82 times higher in the meat-eating USA than in plant-eating Kenya. Women eating meat daily have a 200% higher risk of breast cancer – regardless of what else is eaten.
Animal foods linked to early menstruation
Japanese meat-eaters have 8 times higher rates of breast cancer than Japanese vegetarians. Rural vegetarian Indian women get breast cancer at a rate 400% lower than American women. A high meat diet gives girls a 75% higher risk of having their first period by age 12. Experiencing menstruation earlier means a far higher risk of breast cancer.
Girls experiencing their first period at age seven have doubled in the last 10 years alone
Girls on a high-meat diet in England, Denmark and USA are now hitting puberty at ages 7-10. American girls on the typical modern high-meat diet get their first period at an average age of just 11. Rural Chinese girls on a plant-based wholefood diet get their first period at an average age of 17. Researchers in England have found that higher levels of IGF1 and other hormones in girls are associated with the earlier onset of menstruation.
What increases IGF1 at an earlier age?
The typical modern diet high in meat, dairy fat and refined sugar-rich foods.
Breast Cancer & Lifestyle
Smoking raises your breast cancer risk by 70%. There are over 150 NZ breast cancer cases every year due to second-hand smoke. Regular exercise lowers breast cancer risk. Getting just 6 hours sleep per night raises your breast cancer risk 62%. Alcohol is possibly the biggest single cause of breast cancer. There are 2,600 cases of Australian breast cancer from alcohol alone each year. Regular sunlight directly on the skin (without getting burnt) lowers breast cancer risk by 75% due to the delivery of vitamin D.
- There is NO drug cure for breast cancer
- Over 90% of breast cancer cases have no family history
- Over 90% of breast cancer cases ARE NOT GENETIC
- Your genetic odds of breast cancer are actually less than 1%
- If you want to avoid breast cancer then make the healthy GOLDEN choices and avoid the known breast cancer triggers
- Everything about breast cancer from prevention, to treatment, to support, to recovery, can be helped by a healthy plant-based wholefood diet and smart lifestyle changes
The research, studies and food recommendations from the WCRF & AICR, 2017, to help lower your risk of, and to prevent, breast cancer, are built around following; a no-alcohol, plant-based wholefood diet.

- The Interagency Breast Cancer and Environmental Research Coordinating Committee 2013 Report “Most breast cancers occur in people with no family history, so environmental factors – broadly defined – must play a major role in the etiology of the disease. Prevention is the key to reducing the emotional, physical, and financial burden of breast cancer. By urgently pursuing research, research translation, and communication on the role of the environment in breast cancer, we have the potential to prevent a substantial number of new cases of this disease in the 21st century”.
- “We found that women who ate the most red meat in adolescence or early adulthood had an increased risk of developing breast cancer later in life. One serving a day increment in red meat intake during adolescence was associated with a 22% higher risk of premenopausal breast cancer and each serving per day increment during early adulthood was associated with a 13% higher risk of breast cancer overall. Our analysis took into account most of the known breast cancer risk factors, and we adjusted for smoking, alcohol intake, age, hormone therapy, and oral contraceptive use. Still red meat was one the important breast cancer risk factors. If women decrease the amount of the red meat they eat—for example, having it once a week instead of twice a day—they will decrease their risk of developing breast cancer. And because red meat is not the only risk factor for risk of breast cancer, we suggest that women adopt a healthy lifestyle: drink less alcohol, don’t smoke, and get some physical activity” Scientist Maryam S Farvid, Harvard School of Public Health, October 2014.

- “Higher red meat intake in early adulthood may be a risk factor for breast cancer, and replacing red meat with a combination of legumes, poultry, nuts and fish may reduce the risk of breast cancer”. Substituting one serving/day of legumes for one serving/day of red meat was associated with a 19% lower risk among premenopausal women. Substituting one serving/day of legumes for one serving/day of red meat was associated with a 15% lower risk of breast cancer among all women. Substituting one serving/day of combined legumes, nuts, poultry, and fish for one serving/day of red meat was associated with a 14% lower risk of breast cancer overall.
