This study assessed the correlation between micronutrient intakes and immune system function in human immunodeficiency virus (HIV)-infected patients. CD4 cells were counted in 119 patients. CD4 cells are white blood cells that boost the immune system. Their number is reduced in HIV-infected patients. The results showed that higher intakes of vitamin A and D increased the number of CD4 cells in HIV patients, thus indicating an improved immune function. More details can be found in the study.
