Abstract

Vegetables play an important role in healthy diet. Recently, there has been an increase in the demand for functional foods, which have positive effect on the body. They contain vitamins and minerals that have an important role in maintaining health. Among vegetables, lettuce is popular among consumers due to its beneficial dietary effect and also because it can be consumed as fresh vegetable throughout the year. Due to its short growing season, it is a very good experimental test plant. In our experiment, tried to answer the question whether lettuce can be a functional food, and whether the increase of zinc content of the nutrient solution increases the zinc content of lettuce heads.
