The Claim
Aspartame induces chromosome aberrations in human blood cells at concentrations that reduce cell viability, indicating that genotoxic effects are secondary to cytotoxicity rather than resulting from direct DNA damage.
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.
Aspartame causes structural damage to chromosomes in human blood cells at concentrations that also kill cells, and this damage occurs because the cells are dying, not because aspartame directly breaks DNA.
See the scientific wording
Aspartame induces chromosome aberrations in human blood cells at concentrations that also reduce cell viability, suggesting that genotoxic effects may be secondary to cytotoxicity rather than direct DNA damage.
Aspartame breaks down into methanol, which turns into formic acid inside blood cells. Formic acid blocks a key energy-producing machine in the cell, causing energy levels to drop and cells to die. When too many cells die, their DNA gets damaged and chromosomes break apart during cell division.
What the research says
1 studyThe study found that aspartame breaks chromosomes in blood cells only when it kills so many cells that they’re dying — not because it directly damages DNA. When cells are still mostly alive, no chromosome damage happens.
