Type of fat you consume directly affects the strength of your immune cells
A study by the University of Queensland has shown that diet can alter the fat composition of T cells, making them more resistant to death and increasing the effectiveness of vaccines and cancer therapies. An international team of scientists has discovered that a diet with a lower ratio of polyunsaturated fatty acids (PUFAs) to monounsaturated fatty acids (MUFAs) significantly strengthens T cells. These immune cells are responsible for protecting the body from infections and tumors, but they are highly vulnerable to a specific type of cell death caused by the accumulation of oxidized fats. When these fats destroy the outer membrane of a cell, the immune system becomes weaker.
The type of fats we eat is directly incorporated into the structure of T-cells. Foods rich in monounsaturated fats, such as olive oil and avocados, make cell membranes more resistant to oxidation. In contrast, an excess of polyunsaturated fats (found in fatty fish and soy) without proper balance can make cells more fragile. Scientists emphasize that lipid metabolism is a critical part of the immune system’s overall functioning.
Experimental models have shown that changing the composition of fats in the diet helps follicular T-helpers to more effectively stimulate the production of antibodies. This means that proper nutrition can significantly increase the protective effect of vaccination. In addition, more resilient T-cells begin to multiply and attack tumors more actively, which opens up new opportunities to improve the results of cancer treatment and prolong the lives of patients.
In the future, optimizing a patient’s diet may become an accessible way to enhance immunity, used in conjunction with immunotherapy. Although the exact ideal ratio of fats in the diet has yet to be determined through further research, it is already clear that nutrition is a powerful tool for managing the “viability” of our immune cells. This discovery suggests that food should be viewed not just as a source of energy, but as a way to directly modify the immune system to combat severe diseases.
