The present study deals with the documentation and study of food potential of some traditional wild edible fruits, consumed by tribal communities and village peoples of Nagapattinam district of Tamil nadu, India. Numbers of plant species were documented as wild plants used for food purposes along with their nutritional food value and medicine from the study area. It has been observed that the traditional knowledge is sharp and valuable. The fruits are rich in minerals and carbohydrates. They provide the minerals like sodium, potassium, magnesium, iron, calcium, phosphorus etc. They can be used as remedy for various diseases. This type of study could contribute to educate the younger generation about the importance of wild edible fruits. These wild edible fruit plants can be incorporated as border plants or fence crop along with the commercial crop plants. This will improve planting pattern, food scarcity, economical wealth in villages and tribal areas and also helps in regeneration of barren waste lands.
