The immunity in our bodies comes from very special and diverse cells in the blood. With respect to cell-mediated immunity, retinol is important in the activation of T cells (73), and vitamin A deficiency may affect cell-mediated immunity by decreasing the number or distribution of T cells, altering cytokine production, or by decreasing the expression of cell-surface receptors that mediate T-cell signaling (56). Vitamin C helps NK cells track and destroy tumor cells as well by reducing the shielding effect of platelets (blood clotting cell fragments) that would prevent NK cells from destroying them. Vitamin C is also an essential part of your skin’s defense system, where its antioxidant properties enable it to help strengthen your skin’s natural barriers against environmental damage.

Leptin resistance has been documented in mouse models of obesity, but more research is needed to better understand leptin resistance in human obesity (257). With respect to innate immunity, zinc deficiency impairs the complement system, cytotoxicity of natural killer cells, phagocytic activity of neutrophils and macrophages, and immune cell ability to generate oxidants that kill invading pathogens (188-190). These cells express surface receptors that identify pattern recognition receptors that are unique to pathogenic microorganisms but conserved across several families of pathogens (Figure 1) (2, 11). As the body is not able to make vitamin C on its own, it is very important to include plenty of vitamin C-rich foods in your diet, and not just in winter.
