As parents, we always strive to provide the best care and support for our children. When it comes to health, especially concerning serious illnesses like cancer, it’s natural to seek out information that can help us make informed decisions.
One question that frequently arises is whether sugar consumption contributes to cancer development or progression. In this article, we will examine the link between sugar and cancer, dispel common myths, and offer practical advice for maintaining a healthy diet.
The “Sugar Feeds Cancer” Narrative: Fact or Fiction?
The notion that sugar fuels cancer cells has been circulating since the 1920s when a German physiologist observed that some tumor cells consumed more glucose than healthy cells. Consequently, low-sugar diets emerged, promising to cure cancer. However, recent scientific research suggests otherwise.
While diets high in added sugars may increase the risk of developing cancer over a lifetime, cutting out all sugars does not combat existing tumors. Glucose is an essential energy source for all cells, including healthy ones.
According to Philipp Scherer, a diabetes researcher at UT Southwestern Medical Centre, the brain and many types of cancers utilize glucose for their metabolic needs. However, it’s worth noting that some cancers primarily rely on fat as their primary energy source, dispelling the notion that all cancers prefer glucose.
The Link Between Excess Sugar Consumption and Cancer
Although sugar itself is not a carcinogen, excessive consumption of added sugars, such as those found in cookies, cakes, and soft drinks, has been associated with an increased risk of cancer. Several studies published in 2018 highlighted the connection between added sugar and sugary beverage consumption with an elevated cancer risk. Overindulging in sugar can trigger chronic inflammation, which may damage cells, potentially leading to cancerous changes.

Furthermore, excessive sugar intake can compromise the immune system, making it easier for cancer cells to spread. Additionally, sugar can alter metabolism, contributing to obesity and diabetes, conditions that heighten the risk of developing cancer.
Sugar and Cancer Patients: Managing Diet without Fear
If you or your loved one has been diagnosed with cancer, it’s essential to understand that eliminating sugar from the diet is not a solution to slow or stop cancer growth. At this point, the cancer itself drives its progression, not sugar intake. However, naturally occurring sugars found in dairy products, fruits, and vegetables are integral to a healthy diet.
Natalie Ledesma, an oncology dietitian at the UCSF Helen Diller Family Comprehensive Cancer Centre, suggests that patients focus on avoiding excess added sugars. In particular, patients with certain solid tumors, like breast, colon, and prostate cancers, have been associated with worse outcomes and higher mortality rates when consuming excessive added sugars.
Maintaining a Healthy Diet and Lowering Cancer Risk
While it’s crucial for everyone, including cancer patients, to avoid diets high in added sugars, it’s equally important not to develop a fear of food. Striking a balance is key. Following a healthy diet that includes an abundance of whole fruits and vegetables is an effective way to lower cancer risk.
Studies have shown that Mediterranean diets align with these goals and help reduce the risk of cancer. When consuming carbohydrates, pairing them with protein, fiber, and fat can prevent glucose spikes that may impact metabolism and increase cancer risk. For example, enjoying an apple slice with a small amount of peanut butter offers a satisfying and balanced snack.

In terms of sugar intake, Stacy Shawhan, an oncology dietitian at the University of Cincinnati Cancer Center, recommends adhering to the guidelines provided by reputable health organizations. The US Department of Agriculture suggests limiting added sugar intake to twelve teaspoons per day, while the World Health Organization recommends an even lower intake of six teaspoons per day.
Sugar Substitutes and Cancer: What We Know
The impact of sugar substitutes on cancer and cancer risk remains inconclusive. As experts continue to study this area, it is advisable to exercise caution and avoid excessive consumption of sugar substitutes. Instead, consider naturally sweet alternatives when sweetening recipes.

Natalie Ledesma prefers incorporating bananas, frozen berries, and applesauce into her non-dairy ice creams. Additionally, spices like cinnamon or ginger can provide natural sweetness without adding extra calories or sugar.
Promoting a Healthy Lifestyle for Cancer Prevention
While the relationship between sugar and cancer is complex, maintaining a balanced and nutritious diet is crucial for overall well-being and cancer prevention. Focus on consuming whole foods, limit added sugar intake, and incorporate a variety of fruits, vegetables, proteins, and healthy fats into your meals. By making informed dietary choices, you can contribute to your long-term health and well-being.
Remember, if you or a loved one is facing cancer, consult with a healthcare professional, such as an oncology dietitian, for personalized advice and guidance on maintaining a healthy diet during treatment and recovery.
