{"abstract":"The purpose of the study was to determine how well the school lunch program affected students' dietary needs and academic performance. It took place at Tagpaco Elementary School in the 2022–2023 school year. To collect the necessary data, the study used an experimental research design. The weighted mean, standard deviation, and standard t-test were applied to the study's problem statement. According to the results, there was a substantial difference in the learners' Body Mass Index (BMI) before and after being exposed to the feeding program. The Body Mass Index (BMI) and academic achievement of the study's participants had no discernible association. Therefore, this suggested that there were other factors that affected the academic performance of the learners other than the Body Mass Index (BMI). It was important also to note that a weak positive correlation may still exist, but it was not strong enough to be statistically significant. It was recommended to continue the conduct of the feeding program and plan even more meals that were nutritious for learners who were subjected to school feeding. The school administration should continue to look forward to potential sponsors that would help the school in sustaining the feeding program. This research showed the effectiveness of the feeding program in the nutritional status of the learners but not in the academic performance of the learners.","abstract_source":"original","authors":["Karl Vincent Macarandan","Omar Hussien"],"date":"2024-09-04","doi":"10.5281/zenodo.13683786","id":3540,"issue":8,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"9b13c9183de4f840b8047840f3a42a04335b9a22c99d8099037fd229539fa065","schema":"scimatic-article/1","title":"Effects of the School Based Feeding Program to the Nutritional Status and Academic Performance of the Learners","volume":24}
