Does sugar feed cancer?

Does sugar feed cancer?
In this article

Many patients with cancer often hear stories that sugar feeds cancer. This causes them to worry about consuming sugar. All cells, including cancer cells, need sugar (blood sugar) for energy. There is no scientific evidence that consuming more sugar feeds cancer cells. Similarly, consuming less sugar does not make cells grow more slowly.

The main problem is that too much sugar contributes to fat accumulation and obesity, which increase cancer risk. The sugars we mean are those used in sweetened drinks, cookies, cakes and other ultra-processed foods. These sugars have very little nutritional value. Apart from providing calories, they contribute very little to the diet. They can lead to unhealthy weight gain. Foods high in refined sugars can cause insulin resistance, cardiovascular diseases and obesity. The findings that obesity increases cancer risk are clear.

Should I stop consuming sugar?

"Should I eliminate all sugar from my life during cancer treatment?" If you ask this, the answer is "No!".

There may be times during treatment when you must not stop taking in calories or become dehydrated. At such times, where the calories come from is less unimportant. Nevertheless, patients and their relatives may be avoiding sugary foods such as rice pudding and milk pudding. If you do not have diabetes or are not taking a medication that restricts sugar consumption, enjoying a piece of dessert can be a source of happiness.

You can enjoy a dessert of your choice by controlling the portion

As your appetite returns, you can make healthier choices. You can talk to your oncologist or dietitian and identify foods that may be better for you.

Not all sugars are bad. The sugar naturally found in fruit is part of a balanced diet. Other healthy sugars are vegetables, whole-grain carbohydrates and low-fat dairy products.

There is no scientific study showing that a diet without sugars is healthy. The American Heart Association does not recommend consuming more than 6 teaspoons (24 grams) of sugar for women and more than 9 teaspoons (36 grams) for men.
