Dietary fat ratios impact the strength of immune cells and ability to fight disease

The types of fats we consume directly impacts the survival and strength of the body’s immune cells and ability to fight disease, researchers have found.

A University of Queensland team led an international collaboration that found diet could change the fat composition inside T cells – the immune cells that help protect a person from infections and cancer.

Professor Di Yu of UQ’s Frazer Institute said the research showed a diet with a lower ratio of polyunsaturated fatty acids (PUFAs) to monounsaturated fatty acids (MUFAs) makes T cells much more resilient and resistant to cell death.

The findings mark a profound leap in understanding of how our diet directly impacts immune system function.


Our immune system relies on T cells to manage the body’s immune response.
