The immunity system represents the capacity of an individual to defend their health against physical, emotional, and environmental challenges. The vitality of an individual is represented through various indicators of health. Although very complicated, digestion, elimination, and energy are some of the simple examples to represent the efficiency of metabolism functions of the body; helping to harvest energy and nutrition from food, as well as elimination of toxic burden, keeping the body nourished and clean.
According to Vedic scholars and Maharishis of Ayurveda said that the key to enhance your immunity can be done through the meals you intake.
Any food that transforms quickly into ojas is good for immunity. If food causes ama, it's bad for immunity.Ojas is the end product of complete digestion that creates radiant good health, stable emotions, and immunity. Ama, the digestive impurities caused by eating hard‐ to‐ digest food or by unhealthy eating habits, creates the opposite effects‐ it compromises immunity and health.Maharishi Ayurveda uses the seed‐land theory to explain how immunity works. In this analogy, the human body is like the land, and infection is the seed. Ama and other impurities make the body fertile for infection.If you want to keep the seeds of infection from sprouting, you must take care to create ojas in your body, not ama.
