Will Eating Sugar Make My Cancer Worse?

Be careful, if sugar is not consumed with the care it can generate different problems in our body!

Will Eating Sugar Make My Cancer Worse?

You may have read or heard something about “sugar feeding Cancer,” leading you to wonder if you should stop eating sugar for fear of feeding Cancer growth.

Research supports the notion that cancer cells consume more sugar than normal cells, but there is no conclusive evidence proving that eating sugar will make Cancer grow or spread more quickly or that cutting out sugar will slow down its growth.

All cells in our bodies, including cancer cells, need sugar (glucose) for energy. Our bodies have several back-up strategies to keep blood sugar levels normal. Even without eating carbohydrates, your body will make sugar from other sources, including protein and fat.


During cancer treatment and recovery, our bodies need energy. If you are restricting your diet under the assumption that you are helping, you may, in fact, be depriving yourself of sources of energy that you need to fight Cancer.

Now comes the but — namely, that this doesn’t mean that a high-sugar diet is healthy. Eating too many calories from sugar has been linked to weight gain, obesity, and diabetes, which are all risk factors for the development of Cancer.
