Breast cancer prevention: Physicians call for less meat and dairy in US dietary guidelines

The key issue is not whether diet matters at all, but how confidently we can translate broad nutritional patterns into breast cancer prevention advice. Surveys can show awareness gaps and public beliefs, but they cannot prove that changing guidelines alone will change cancer outcomes. That distinction matters when headlines move quickly from opinion to policy.

The most defensible takeaway is about pattern, not a single โ€œsuperfood.โ€ Plant-forward eating is often associated with better cardiometabolic health, which may indirectly support long-term cancer risk reduction, but the evidence is rarely simple enough to isolate one food as protective on its own. Fiber-rich foods, legumes and minimally processed meals are practical examples of that pattern.

There is also a communication problem hidden inside the nutrition message. Misunderstandings about soy, protein quality, and what a plant-based diet actually looks like can make prevention advice feel contradictory or unrealistic. For many people, the barrier is not lack of willpower but confusion, habit, cost, access and cooking skills.

So the most useful reading of this story is cautious and actionable: nutrition can be part of cancer-risk reduction, but it works best when framed as one piece of a broader lifestyle picture alongside screening, physical activity, body-weight management and other evidence-based prevention steps. Strong claims should be treated more carefully than the underlying public-health goal.


A new US-wide survey by the Washington D.C.-based Physicians Committee for Responsible Medicine (PCRM) reveals that only 28% of women are aware of the importance of a healthy diet for lowering the risk of developing breast cancer. โ€œAn overarching problem is the US dietary guidelines โ€” they must be revised to decrease the focus on dairy and meat despite their known links to health problems,โ€ Stephanie McBurnett, a registered dietitian with PCRM, tellsย Nutrition Insight. โ€œInstead, the guidelines should focus on the multitude of benefits of a plant-based diet. Additionally, physicians and other health care providers arenโ€™t adequately trained in nutrition. That is a huge barrier to the lifesaving message of dietโ€™s role in disease prevention reaching patients,โ€ she details. The survey collected the responses of 2,017 US women interviewed in July 2024. Responding to a question about the specific foods they see as having the potential to reduce breast cancer risk, 23% mentioned vegetables and 16% fruits. Soy products were identified as beneficial by 17% of participants, while 16% wrongly stated that they believe soy increases the risk of developing breast cancer. โ€œHealth care providers have a huge responsibility, but it all begins with ensuring theyโ€™re appropriately educated on nutrition.โ€

The results from theย surveyย indicate that awareness of the preventive steps women can take to prevent the development of breast cancer has not been increasing. A similar survey of 510 women conducted in 1995 yielded similar results. Given that awareness has not significantly increased since 1995, McBurnett calls for new strategies to effectively communicate the link between nutrition and cancer. โ€œMedical schools have to begin acknowledging and plugging curriculum gaps in nutrition when it comes to training the next generation of physicians,โ€ she asserts. โ€œStates can increasingly consider passing laws that enhance nutrition education for physicians,โ€ she continues. โ€œFor example, New York Governor Kathy Hochul recently signed into law a bill that will ensure physicians are kept informed about the latest continuing medical education opportunities in nutrition.โ€ โ€œThe new law will help doctors in the state improve patient health outcomes and reduce racial disparities for the millions of New Yorkers struggling with diet-related diseases like type 2 diabetes and heart disease through clinically proven methods like adopting a plant-based diet.โ€ She points out that healthcare advocacy organizations also play a role in bridging โ€œthe nutrition-education gap.โ€ โ€œThe PCRM, for example, provides medical students and other health care professionals with plant-based resources, including workshops and presentations, to change the future of patient care.โ€

Diet tips

Dr. Kristi Funk, a breast cancer surgeon and leading prevention expert from Los Angeles, US, says that it is clear that millions of women have yet to fully realize that what they eat and drink โ€œstronglyโ€ influences their chances of developing breast cancer. โ€œScience shows nearly 50% of cases are preventable through diet and lifestyle, at least in theory, and in my opinion, 80-90% of cases could be avoided.โ€ Neal Barnard, president of the PCRM, similarly states: โ€œPublic education programs on breast cancer have focused on mammograms, which play a vital role, but are not enough. It is essential to empower people with steps they can take to protect themselves, and a healthy diet is at the top of the list.โ€ McBurnett provides examples of foods that align with the low-fat, plant-based diet recommended for breast cancer prevention. McBurnett recommends chickpea-based foods, such as falafel and hummus for breast cancer prevention.โ€œFoods that provide extra breast-boosting power are items rich in fiber like chickpeas, perhaps in a hummus and chickpea falafel wrap, or meals that have soy, the breast superfood, in a shredded tofu taco with all the fixings, including salsa, black olives, roasted corn and avocado.โ€ She encourages women to join the โ€œLetโ€™s Beat Breast Cancerโ€ campaign to be notified of upcoming events, get cancer-fighting tips and to gain access to Funkโ€™s recipes, such as the โ€œCancer-Kicking Buddha Bowl.โ€ The campaignโ€™s e-cookbook also contains healthy plant-based meals, such as a 5-Minute Carrot Cake Oatmeal, a Spicy Tofu Stir-Fry, Bean and the โ€œAvocado Tostitos Supreme.โ€

Plant-based diets can be indulging

A common misconception about plant-based diets that McBurnett faces when recommending a plant-based diet to her patients is the idea that such meals can be boring or unappealing. โ€œContrary to the belief that a plant-based diet is limited to just salad, it actually can include a diverse range of foods. Your plate can be filled with whole grains, beans like roasted chickpeas, sauteed mushrooms and grilled vegetables, for example, ensuring a satisfying and nutritious meal,โ€ she asserts. โ€œDispelling another myth, plant-based diets are not lacking in protein. In fact, research shows thatย Original Postlant-based-proteins-offer-complete-source-of-essential-amino-acids-experts-reveal.html">plant proteins, when consumed in adequate amounts, not only provide sufficient protein, but are also superior for our health.โ€ โ€œUnlike animal-based proteins,ย plant proteinsย are cholesterol-free, lower in saturated fat and rich in fiber, making them a healthier choice.โ€ She brings attention to the PRCMโ€™s directory of plant-based dietitians โ€œwho are well versed on the benefits of eating plant-based diets, as well as the barriers that an individual can face when making their health a priority through diet.โ€ โ€œDietitians and other health care providers are extremely important when it comes to disseminating health information. Dietitians know that what we eat can make a huge impact on health and should be leaned on to provide education to the community,โ€ McBurnett concludes.
