Fatty foods have been proven to harm the heart

Eating high-fat foods can impair the growth of heart muscles and increase the risk of seizures. This was proved by scientists at the University of Reading, the results of the study are published in the journal Biochemical and Biophysical Research Communications. Briefly about the scientific work is described in the press release on MedicalXpress.

According to experts, they were able to demonstrate that a fatty diet clearly damages muscle cells through oxidative stress, while the negative effect is mediated through the Nox2 protein, whose activity becomes excessive. However, the exact mechanism by which Nox2 induces pathological hypertrophy of cardiac tissue remains unknown.

In their experiments, the scientists fed the mice a high-fat diet. As a result, the activity of Nox2 in rodents doubled, which also led to twice the amount of reactive oxygen species involved in oxidative stress. In mice with a knocked-out gene encoding Nox2, which were also fed a fatty diet, the level of oxidative stress did not increase.
