Does Sugar Feed Cancer
There is no conclusive research that proves sugar causes cancerous cells to grow. While it is true that cancer cells need sugar to grow, the same could be said for nearly every cell in the body. If you were to avoid all sources of natural sugars found in grains, vegetables, fruits, milk and beans, you would starve healthy cells, which could result in malnutrition.
There is some evidence that consuming large amounts of sugar that produce a high glycemic indexrapidly increasing blood sugar levelsmay be associated with an increased risk of certain cancers, including esophageal cancer. And a 2010 study found that fructose may fuel the growth of pancreatic cancer. Studies of a high glycemic index diet and cancer risk are mixed, but suggest a high glycemic index diet may increase risk of some cancers, especially in those who are overweight, inactive, which may increase risk of insulin resistance.
Experts recommend you avoid consuming large amounts of refined sugarsthe bad sugars found in soda, candy, cakes, etc.and get your sugar intake from whole foods. Besides being an excellent source of naturally occurring sugar, fruit contains many vitamins, minerals, phytochemicals and fiber that may help with achieving and maintain a healthy body weight, maintain cellular integrity and help support the immune system.
What If Any Is The Link Between Sugar And Cancer
There is no question that obesity is associated with an increased risk of cancer, and that the abundance of carbohydrates in our diet is one of the major foundations on which the worldwide epidemic of obesity is built.
The fundamental basis of obesity is eating more calories than you can burn over a period of time. Many people assume that if a person has a lot of body fat, its because they ate too much fat. That makes intuitive sense, but it isnt the truth. Pretty much all you do with fats that you eat is burn them for energy.
The fats you put into your fat cells are by and large made from carbohydrates. But it took us 25 years to figure that out. And as we learned recently, some groups tried to discourage or prevent that research.
Where Does The Idea That Cancer Is Addicted To Sugar Come From
About 90 years ago, a German scientist named Otto Warburg noticed that tumor cells in a dish tended to consume more glucose than non-dividing normal tissues. He also noticed that although the cancer cells were consuming massive amounts of glucose, they werent taking advantage of the most efficient method of harvesting energy from that glucose, which is to essentially burn it using oxygen in the mitochondria. Instead, they converted the glucose to lactate, leaving much of the energy untapped. This has come to be known as the Warburg effect or Warburg metabolism.
Warburg assumed that cancer cells must have a defect in their mitochondria, because why else would they resort to this inefficient method of obtaining energy? But we now know that Warburg was wrong. Tumor cells possess functional mitochondria and rely on them for energy in some situations.

Over The Course Of About 12 Years 11576 Women Were Diagnosed With Invasive Breast Cancer:
In postmenopausal women, higher glycemic load and higher carbohydrate intake were associated with a significantly greater risk of estrogen receptor negative and estrogen-receptor-negative/progesterone-receptor-negative breast cancers.Glycemic load, glycemic index, and carbohydrate intake were not associated with overall breast cancer risk for all women.
Previous studies have suggested that diets with a higher glycemic load could stimulate insulin receptors in breast tissue or influence other hormones that affect breast cancer risk.

1 in 2 of us will get cancer in our lifetime. All of us can support the research that will beat it.
This post was first published in 2017 but has been reviewed and updated in October 2020.
Theres a lot of confusing information and advice out there around sugar.
Does it cause cancer? Does sugar feed cancer cells, making them grow more aggressively? And how does the sugar we consume through food and drink affect our health, and what can be done about this?
In this post were taking a long hard look at sugar.
Well focus specifically on sugar and cancer, busting some myths and covering what researchers are studying in the hopes of finding new ways to treat people with cancer.
And well cover why the amount of sugar in our diets is cause for concern. A high-sugar diet can be bad news when it comes to cancer risk, but not for the reasons that often appear in the headlines.
But first the basics, what our bodies need sugar for and where it comes from in our diet.

Association Of High Blood Sugar Levels With Treatment Outcomes In Colorectal Cancer Patients
In a retrospective study done by the researchers in Taiwan, they analyzed data from 157 stage III colorectal cancer patients who were classified into 2 groups according to their fasting blood sugar levels one group with blood sugar levels 126 mg/dl and another with blood sugar levels < 126mg/dl. The study compared the survival outcomes and chemoresistance of the oxaliplatin treatment in the two groups. They also carried out in vitro studies to evaluate the impact of an anti-diabetic drug on cell proliferation after administering glucose.
Glucose addition increased the colorectal cancer cell proliferation in vitro. It also showed that administration of an anti-diabetic drug called metformin could reverse the enhanced cell proliferation and increase the sensitivity of the oxaliplatin treatment. The study on the two groups of patients suggested that a high blood sugar may be associated with a higher incidence of the disease relapse. They also concluded that patients with stage III colorectal cancer and high blood sugar levels may exhibit markedly poor prognosis and may develop resistance to the oxaliplatin treatment in a short period.
Findings from this study suggest that high blood sugar can impact the oxaliplatin treatment outcomes in Colorectal cancer patients. Hence, colorectal cancer patients undergoing this treatment may have to avoid very high intake of concentrated sugar.
What We Can Do
Knowing what our own risk factors are is essential, as, when we do, we can work toward choosing risk reducers that take on new meaning because they are personal.
And this is empowering.
So, what should we remove?
- Processed meats
- Red meat
- Refined grains
- High-fat dairy products
What should we limit ?
And, what should we include?
General Cancer Nutrition Guidelines
- Moderate meals that include lean protein, whole grain carbohydrate, and healthy fat to achieve and maintain balanced blood glucose levels
- MyPlate method for meal structure
- Plant-based diet that includes a rainbow of phytochemicals that optimize our bodies in fighting cancerchoose as many colors as possible daily6
Lastly, physical activity is recommended as appropriate per the ability of an individual. And dont forget adequate hydration from water and other non-caffeinated sources as the power of hydration is often underestimated! Remember that our bodies are largely comprised of water and need adequate hydration to function properly and optimally.
In total, this inverted lens that moves the focus off of sugar as a culprit and onto a whole food-based diet in combination with physical activity is the key to personal empowerment and breast health.

Cancer And Sugar: Does Changing Your Diet Starve Cancerous Cells
You may have heard that ‘sugar feeds cancer cells’, fuelling their rapid growth.
Or that eliminating sugar from our diet can starve or stymie cancer growth.
But is there any truth to these beliefs?
Well, the oft-repeated claim that sugar feeds cancer cells is true in a strict sense and that may seem scary. But of course, it’s not the whole story.
The reality is that alongside cancer, sugar feeds most cells in the body and is vital to our everyday function.
The most simple forms of sugar are single molecule sugars, like glucose and fructose. These can combine to form more complex sugars like table sugar .
All carbohydrates are sugars too, meaning foods you wouldn’t think of as sugary like potatoes, pasta and grains do eventually break down to simple sugars in the body.
And sugar plays a critical role in fuelling the body’s cells. Glucose, either eaten directly or broken down from carbohydrates, is critical to cell functioning.
This is the grain of truth at the heart of the concern around sugar and cancer yes, sugar feeds cancer cells.
But it fuels them in exactly the same way it feeds all other cells in the body.
And our body can’t dictate which cells it sends energy to and which it doesn’t.
What About Ketogenic Diets Can They Lower Your Risk Of Developing Cancer
A ketogenic diet is when you restrict carbohydrates and eat more fat. On a ketogenic diet, youre burning fats and your metabolic rate goes up just a little bit. It makes you use more calories from what you eat in just maintaining yourself every day. And you have very little ability to store the extra fats that you eat, so you pee them out as ketones. Thats why its called ketogenic. And its why people lose weight on a ketogenic diet theyre getting rid of more of the calories that they consume.
So does a ketogenic diet help you decrease your chances of getting cancer? If you are overweight and it helps you lose weight, then yes, it does. If you can tolerate it, its perfectly fine. I was on a ketogenic diet for two and a half to three years back in 2004, 2005. I lost 40 pounds. But I eventually gave it up and Ive since gained back most of the weight. Its almost impossible to stay on a ketogenic diet for any significant length of time. Food just doesnt taste the same. But I still dont eat a lot of refined sugar in any way, form, or shape.
Now does a ketogenic diet matter once you have cancer? Does it help improve your cancer care? We have no evidence that thats true, or that you should use a ketogenic diet while youre receiving cancer treatment. In fact, a person going through cancer treatment might benefit from additional calories and nutritional support to help his or her body recover.

Association Of Consumption Of Sugary Drinks With Breast Cancer Risk
A recent meta-analysis used data from the French NutriNet-Santé cohort Study which included 1,01,257 participants aged 18 and over. The study evaluated the association between consumption of sugary drinks such as sugar sweetened beverages and 100% fruit juices, and artificially sweetened beverages and cancer based on a questionnaire based data.
The study suggested that those who had an increased consumption of sugary drinks were 18% more likely to develop overall cancer and 22% more likely to develop breast cancer compared those who did not or seldom consume sugary drinks. However, the researchers suggested more well designed prospective studies to establish this association.
A similar study was conducted which evaluated data from 10,713 middle-aged, Spanish females from the Seguimiento Universidad de Navarra cohort study with an average age of 33 years, who didnt have a history of breast cancer. The study evaluated the association between consumption of sugar-sweetened beverages and incidence of breast cancer. After a mean follow up of 10 years, 100 breast cancer incidences were reported.

A Little Carbohydrate Background
Carbohydrates are one of three macronutrients necessary in the diet to support energy, growth, and life, and include a wide range of starches, sugars and fiber.
Some sugars are NATURALLY OCCURRING, like the sugar found in fruits, vegetables, whole grains, and some dairy products. Other sugars, such as high fructose corn syrup, are produced commercially and then ADDED to foods.
Carbohydrate is a category that includes a wide range of starches, sugars , and fiber.
There are many TYPES of sugar, which are classified by chemists according to their chemical structure i.e. monosaccharides and disaccharides , and several FORMS of sugar, i.e. glucose, fructose and galactose, which come together to createeven more forms of sugar, like the lactose in milk , and the maltose found in molasses
The concern for newly diagnosed and metastatic patients is that sugar feeds cancer, making it grow faster and uncontrollably, hastening its potential and/or further spread throughout the body.
For patients undergoing treatment, there may be concern that sugar interferes with chemo and/or radiation. For women without a breast cancer diagnosis or are NED post-treatment, the concern is that sugar will cause an initial cancer diagnosis or a recurrence.

Carbohydrates Raise Insulin Levels Could Abnormal Levels Of Insulin Lead To Cancer
Insulins job is to tell the cells in our body, Hey! Theres a lot of glucose. We should use it. Therefore, if we could get people to produce less insulin, they might do better. But the real root problem of the worldwide obesity epidemic and cancer as a result of obesity has to do with too much caloric intake. It has little to do with abnormal insulin signaling.
Should We Cut Off Sugar Completely From Our Diet To Prevent Cancer
Cutting off all forms of sugar from the diet may not be the right approach to avoid cancer, as the healthy normal cells also require energy to grow and survive. However, keeping a check on the following may help us stay healthier!
- Avoid regular intake of high sugar sweetened beverages, sweetened carbonated beverages, high concentrated sugary drinks including certain fruit juices and drink lots of water.
- Take just the right amounts of sugar as part of our diet by having whole fruits instead of separately adding table sugar or other forms of sugar to our foods. Restrict the amount of table sugar in your beverages such as tea, coffee,milk, lime juice and so on.
- Reduce the consumption of processed foods and include more fruits and vegetables.
- Avoid sugary and fatty foods and keep a check on your weight, as obesity is one of the major risk factors for cancer.
- Take a personalized cancer diet which supports your treatment and cancer.
- Along with healthy food, do regular exercises to stay healthy and avoid gaining weight.
What food you eat and which supplements you take is a decision you make. Your decision should include consideration of the cancer gene mutations, which cancer, ongoing treatments and supplements, any allergies, lifestyle information, weight, height and habits.

What Are Artificial Sweeteners And How Are They Regulated In The United States
Artificial sweeteners, also called sugar substitutes, are substances that are used instead of sucrose to sweeten foods and beverages. Because artificial sweeteners are many times sweeter than table sugar, much smaller amounts are needed to create the same level of sweetness.
Artificial sweeteners are regulated by the U.S. Food and Drug Administration . The FDA, like the National Cancer Institute , is an agency of the Department of Health and Human Services. The FDA regulates food, drugs, medical devices, cosmetics, biologics, tobacco products, and radiation-emitting products. The Food Additives Amendment to the Food, Drug, and Cosmetic Act, which was passed by Congress in 1958, requires the FDA to approve food additives, including artificial sweeteners, before they can be made available for sale in the United States. However, this legislation does not apply to products that are generally recognized as safe. Such products do not require FDA approval before being marketed.
