The Claim
In mice fed an ultra-processed diet, treatment with N-acetylcysteine reduces myocardial oxidative stress, HMGB1 accumulation, inflammation, and cardiac dysfunction.
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.
In mice eating a highly processed diet, N-acetylcysteine lowers levels of oxidative stress and inflammation in the heart and improves heart function.
See the scientific wording
In mice fed an ultra-processed diet, antioxidant treatment with N-acetylcysteine reduces myocardial oxidative stress, HMGB1 accumulation, inflammation, and cardiac dysfunction, supporting the role of reactive oxygen species as a key mediator in this pathway.
Eating ultra-processed food causes heart cells to produce too much stress, which turns on a protein called calpain-1. This protein makes mitochondria leak out harmful molecules called reactive oxygen species. These molecules change the shape of another protein, HMGB1, forcing it to leave the nucleus and escape the heart cell. Once outside, HMGB1 signals immune cells to become inflammatory, causing swelling, tissue scarring, and reduced heart pumping ability.
What the research says
1 studyIn mice eating junk food, giving them an antioxidant called NAC helped their hearts work better by reducing harmful stress and inflammation, and stopping a trouble-making protein (HMGB1) from causing damage.
