Immune system weakening has long been attributed to aging and poor lifestyle choices, but according to an October 2023 study in Nature Communications, the key reason for this immune system decline is dysfunctional mitochondria, your cells' powerhouses, particularly the mitochondria found in T cells (a type of immune cell).
When the mitochondria don't work well, the T cells don’t have the energy required to perform their functions, which leads to a decline in immune system function. This in turn, results in an inability to ward off both acute infections and chronic diseases.
The study identifies glycolysis as an inefficient way to produce energy, and the reactive oxygen species (ROS) produced in the process damage T cells
The findings suggest reversing mitochondrial damage could improve immune response and cancer therapies
Excess linoleic acid (LA) intake and estrogen dominance are major contributors to mitochondrial dysfunction
Strategies that will improve your mitochondrial function include lowering your LA intake, reducing stress and taking a niacinamide supplement
