Recently you may have noticed a lot of stories in the news about sugar and cancer. Mostly there is a lot of chatter about sugar causing cancer. With so many different reports it is hard to make sense of it all. Is there any truth to these claims?
The short answer is no! Let’s take a look at why.
What is sugar?
Sugar is just another word for simple or small carbohydrate. Simple carbohydrates make up sweet tasting foods like table sugars or fruits. Smaller carbohydrates come together to form more complex carbohydrates that are found in grains, vegetables legumes, nuts, seeds, milk and other dairy. The important thing to note is that all carbohydrates get broken down into the same molecules by your body. Your body cannot tell the difference between the carbohydrates in vegetables or the carbohydrates in table sugar. It will break it down into the same thing.
Sugars feed all of the cells of the body
That’s right. Sugars (carbohydrates) give energy to all cells of the body, including cancer cells. It would be great if sugars only “fed” cancer cells. Then you could take it out of your diet and prevent cancer cell growth. Sadly that is simply not the case. Sugars give energy to all cells in the body, which in turn fuels activity and exercise as well as helps to maintain muscle in your body. Depriving your body of sugars can actually be harmful and it is not recommended.
Can you eat as much sugar as you like?
No! According to Pauline Wisdom-Gilliam, a Registered Dietitian at the Odette Cancer Centre, “Sugar, when eaten in the right amounts (especially if paired with protein and/or healthy fat – eg. a piece of fruit and some nuts), can fit into a well balanced diet.”
How can you make sugars a healthy part of your diet?
Wisdom-Gilliam has put together a list of tips to help make sure sugars are a healthy part of your diet.
Too much sugar = thumbs down
- Too much of anything is a bad thing. Sugars are no different. Too much sugar can result in excess weight and body fat. Fat cells produce high levels of hormones and proteins that can cause inflammation that is linked to increased risk of cancer and other chronic diseases.
Watch out for added sugars
- Added sugars are any sugars that are added to food during processing and preparation. Foods like pop, candy, chocolate and some cereals all have added sugars.
- Follow the American Heart Association recommendations on added sugar intake:
- Women – 6 teaspoons/day (25 grams)
- Men – 9 teaspoons/day (37 grams)
Whether sugar is natural or refined, worry about the amount
- To the body a sugar molecule is a sugar molecule whether refined (table sugar, corn syrup) or unrefined (molasses, honey, agave nectar, maple syrup)
- The amount is the problem, stick to 25 grams a day for women and 37 grams a day for men.
Eat as many whole, healthy, unprocessed foods as you can
- Eat vegetables, fruit, whole grains, legumes, nuts and seeds. They not only are a great source of sugars but they contain vitamins, minerals, fiber and antioxidants.
The bottom line is all foods with sugar feed the cells within your body, including cancer cells. If you don’t include any sugar in your diet it means your body does not get the fuel it needs to function. Eating a variety of foods in moderation is the best way to stay healthy and ensure your body is getting all the nutrients it needs.
American Heart Association recommended added sugar intake.
Nutrition for caregivers
Taking care of a loved one with cancer can be hard on you mentally and physically. Keeping yourself healthy is an important part of being a caregiver but how do you juggle your own health and wellbeing with the needs of your loved ones with cancer?
Tracey Rapier, a Registered Dietitian at the Odette Cancer Centre, has put together a list of health tips for caregivers to keep energy levels up and eat a healthy diet:
- Dehydration can cause a variety of problems from simple thirst to low blood pressure and increased heart rate. At extremes dehydration can affect your kidneys which can be dangerous.
- Water or other calorie free drinks like herbal tea are the best choices if you are trying stay hydrated throughout the day. The 8 cups of water a day rule is great but the amount of fluids you must drink per day depends on many factors like how much you exercise.

Eat enough fruits and vegetables
- Canada food guide recommends 7-10 servings of vegetables and fruit per day. A serving is the equivalent of a piece of fruit that fits the palm of your hand like a medium apple or banana or a cup of diced vegetables.
- Fruits and vegetables have also been shown to boost immune function, which will help prevent you from getting sick so you can continue to provide the care your loved ones need.
