Abstract: The paper's focus is on reviewing of the constituents of the foods that help sustain life, aid growth and maintain the body systems and organs in general, the foods that are immunity boosters and those specific foods having within them the medicinal properties. Going by the popular saying that "all drugs are chemicals, but all chemicals or not drugs?, the study is an attempt to find the rationale behind some foods or food constituents which have immunity enhancing and medicinal properties. The search for the study is carried out with the hypothesis that the ?foods are for life sustenance, immunity and disease fighting". The foods in general are for providing energy, for growth and maintenance of the body systems, and for the general well-being. Food is responsible for one to be healthy and sickness-resistant too. Thus foods act as immunity boosters to develop the capacity of the body to fight diseases on a preventive mode. Some of the foods, special as they are, act as medicines - directly fighting with the diseases to cure them. The paper covers all types of foods that our body needs, and provides vivid information which will be of guidance to people.
