Advances in Nutritional Science Can Beat Breast Cancer

Evidence shows we can reduce cancer rates – breast cancer particularly – by 90 percent or more by people adopting a Nutritarian  diet. 

Various populations around the world, who eat more natural plants, have less than one twentieth the amount of breast cancer compared to Americans. Even within the United States, some areas have a death rate from breast cancer that is twice as high as those in other areas. A Nutritarian diet is designed to include a full portfolio of the foods that scientific studies have shown to have the most powerful cancer-protective effects. These same foods also slow the aging process. Advances in nutritional science can make winning the war against cancer a reality in our lifetime.

A 2011 meta-analysis of 10 scientific studies found that higher fiber and phytochemical intake was associated with dramatically lower risk of breast cancer.[1] In 2012, another meta-analysis of 16 studies came to the same conclusion.[2] Natural plant foods contain a variety of anti-cancer phytochemicals. Some breast cancer-protective substances that have already been discovered include isothiocyanates from cruciferous vegetables[3], organosulfur compounds from onions and garlic,[4] aromatase inhibitors from mushrooms,[5] flavonoids from berries,[6] lignans from flax, chia and sesame seeds,[7] and inositol pentakisphosphate from beans.[8]

Higher intake of sugar, sweets and white bread, leading to a high dietary glycemic load (characteristic of refined grains and processed foods) is associated with an increase in breast cancer risk.[9] Increased body production of estrogen is also known to increase breast cancer risk.[10] However, fiber binds estrogen in the digestive tract, accelerates its removal, and prevents it from being reabsorbed into the body.[11] In addition, soluble fiber (as shown in studies using prunes and flaxseed) alters estrogen metabolism, preventing cancer.[12] Beans, oats, chia seeds, and flaxseeds provide extra protection due to their high soluble fiber content. Chia and flax are rich in seed-based lignans have been shown to dramatically reduce deaths from breast cancer, even in patients already diagnosed with breast cancer.

The acronym G-BOMBS (Greens, Beans, Onions, Mushrooms, Berries, Seeds) helps women remember the foods with the most powerful protection against breast cancer as determined by scientific studies. These foods contain anti-estrogenic compounds, angiogenesis inhibitors that inhibit tumor development, and isothiocyanates that fuel cellular repair of acquired DNA defects.

The Nutritarian Women’s Health Study (NWHS) is a long-term observational study on the effect of this life-saving Nutritarian diet on overall health, plus the occurrence, recurrence, and progression of chronic diseases (including all forms of cancer, diabetes, heart disease, and stroke). It was launched in October 2016 to document the benefits of this eating style, and potentially change the face of health care in America and the modern world. This unique study aims to show that we can win the war on breast cancer with proper nutrition.

The study’s two-tier approach will examine the effect of a Nutritarian diet on the occurrence, recurrence and progression of chronic diseases, including autoimmune diseases, cancer, diabetes, heart disease, dementia and stroke, with a directed focus on the prevention of breast cancer and the reversal of early-stage breast cancer.

The NWHS is an open-ended observational study conducted by researchers from Northern Arizona University. Principal Investigator Jay Sutliffe, Ph.D., R.D., emphasizes the importance of the study: “This research can move us from fear to freedom, from awareness to action, from disease to dynamic living.”


The goal is to recruit at least 10,000 women during the study. In the first six months, the study has been able to enroll more than 1,200 participants, with another 600 women currently in the process of enrolling. All participants first learn the science and the techniques of the program, and then pledge to follow this nutrient-dense, plant-rich protocol, which includes powerful longevity-promoting, anti-cancer foods. They will report periodically to the study team through questionnaires.

Our goal is to enlist a variety of women, of different ages and different health statuses, in order to study and publish data from the health outcomes of subgroups as well. There are many benefits to enrolling in the study. Two key benefits are:

  1. Participants receive an initial education about the Nutritarian diet, and will have the opportunity to continue to learn from Dr. Fuhrman and the research team about the best ways to promote good health, utilizing optimal nutrition, throughout the study. This benefit is critical to the success of the study, as we hope to demonstrate dramatic effects of a superior diet to lengthen human lifespan, to prevent the common diseases that afflict women as they age, and to improve the quality and enjoyment of life.
  1. This study also offers a unique opportunity to be part of something bigger than ourselves — to help ensure that future generations of women have better information on how to care for their health and the health of their families. From the mid-20thcentury into the 21st, healthcare solutions have been based, to an alarming degree, on pharmaceutical remedies. Yet, time and again, science has illustrated that those remedies are the least helpful, and can often be harmful. The results of this study promise to have an impact on our approach to disease treatment and prevention.


Participants will be asked to fill out periodic surveys and may be asked to submit other medical histories and speak with study team members. Every two years, participants will receive a kit with instructions to have bloodwork completed locally. Those enrolled gain support through a professionally staffed study office, regular blogs featuring study-specific articles, and access to a Facebook group that offers daily administrative support to answer questions and give direction.

How do women learn more about the Nutritarian Diet and the anti-cancer protocol developed by Dr. Fuhrman?

I write books on health and nutrition that everyone can read. However, the women seriously considering participating in this study are given a full package of information we need them to review, including my book Super Immunity, other reading materials, videos, and information about the study to review before making a commitment to participate.

Why aren’t men included in the research?

In the long term, the Foundation certainly plans to do a similar study focused on men’s health and wellness. However, new funding sources need to be established before this can happen.

This is a privately-funded clinical research study with no charge to our participants. Annual study costs are currently over $350k annually. We count on our friends and supporters to help us move this important work forward.
