The Claim
High dietary sugar consumption promotes the growth and progression of cancer.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Consuming large amounts of dietary sugar is associated with increased growth and progression of cancer.

High dietary sugar consumption promotes the growth and progression of cancer
When sugar is consumed in large amounts, cancer cells use it to make energy and building blocks for growth. Sugar triggers changes that turn on genes that help cancer cells multiply, avoid death, and damage their own DNA. It also activates pathways that tell cells to make more proteins and take in more glucose, making tumors grow faster and resist treatment.
What the research says
2 studiesThis study found that cancer cells in the colon use fructose (a type of sugar) to grow faster and resist chemo. When scientists reduced fructose in the mice’s diet, the tumors grew slower and chemo worked better. So eating too much sugar—especially fructose—can help cancer grow.
Study: High sugar diet promotes tumor progression paradoxically through aberrant upregulation of pepck1
When flies with cancer ate a lot of sugar, their tumors grew bigger and they died sooner. But when scientists turned off a specific gene (PEPCK1) that sugar activated, the tumors shrank and the flies lived longer. This shows sugar makes cancer worse.
