Garlic is an important ingredient in nearly every cuisine in the world—and for good reason. Garlic contains the sulfoxide alliin, and when crushed or chewed, alliin turns into allicin. Because allicin is unstable, it converts to sulphur-containing compounds, which are thought to give garlic its medicinal properties. Garlic has been shown to enhance the function of the immune system by stimulating macrophages, lymphocytes, natural killer cells, dendritic cells, and eosinophils. It does so by modulating cytokine secretion, immunoglobulin production, phagocytosis, and macrophage activation.
Garlic is simple to include in most any meal you are preparing. Use it when making roasts, chicken, lamb, and fish. Or even add it to rice or mashed potatoes while boiling for a delicious, flavorful, and healthy kick to your meals.
