The view on fiber has started to change after it was reported that low fiber consumption causes many cases of chronic diseases such as coronary heart disease, appendicitis, diverticulosis, and colon cancer. The purpose of this community service is to provide nutrition education through counseling about the importance of fiber in early childhood. This is because counseling about fiber is still minimal. The method used is a nutrition education method in the form of counseling, such as lectures, exposure, pre- and post-tests, and the distribution of booklets and leaflets related to the material. The results of community service activities found that there was an increase in target knowledge after being given education, with a percentage increase in the good category of as much as 28%. The targets seemed enthusiastic about participating in the activity and increasingly knew that fiber is very important to consume from an early age. It is certainly true that this community service activity can be a solution to increasing knowledge among parents and students about prioritizing fiber intake during the golden period of early childhood growth.Keywords: early childhood, nutrition education, fiber.
