Dietary Recommendations for Cancer Prevention and Supportive Care

According to Marleen I. Meyers, MD, a breast medical oncologist at NYU Langone Health, a cornerstone of cancer prevention lies in a balanced, nutrient-rich diet. Oncologists like Meyers emphasize prioritizing whole foods, particularly fruits and vegetables, over relying on supplements.

The common saying of "eating the perimeter of the grocery store" highlights the importance of incorporating green leafy vegetables and other natural sources of vitamins and minerals. While supplements may be necessary for individuals with documented deficiencies, the general recommendation is to obtain essential nutrients from food. This means choosing an extra serving of vegetables or fruits over processed foods or a plethora of supplements.

For patients navigating cancer treatment and seeking to optimize their health post-therapy, Meyers emphasizes the importance of a colorful diet. This approach pushes for the consumption of a variety of fruits and vegetables, encompassing a spectrum of colors beyond just green. While broccoli is beneficial, Meyers explains how incorporating yellow and orange produce ensures a wider range of vital nutrients. This diverse dietary intake, along with regular physical activity, forms a strong foundation for overall well-being.

Further, Meyers explains that attention to portion control is crucial. Even healthy foods like broccoli and whole grains contain calories. Patients often express concerns about weight gain during or after treatment, particularly when on hormonal therapies. While certain medications can contribute to weight fluctuations, reducing portion sizes across all food groups can be an effective strategy for managing weight. Emphasizing whole, unprocessed foods while maintaining mindful portions empowers patients to take an active role in their health, supporting treatment outcomes and promoting long-term wellness.

“One easy thing that one can do is to just decrease portions across the board, because even broccoli has calories. While you want to be eating broccoli, kale, and whole grains, [with] all of those good foods for you, you do have to be cautious about how much you're eating,” says Meyers.
