Impact of Food Literacy on Consumer's Food Purchasing Habits and Dietary Intake - A Systematic Review

Abstract

Introduction: A well-nourished population represents the sustainable development of a nation. Poor alignment between food intake and dietary recommendations results in consumption of high calorie, low nutrient dense foods. Aims & Objectives: The main goal of this study is to find the relation between food literacy and dietary intake. Secondly, to assess the influence of food literacy on food purchasing habits. Place and duration of study: For this review, collection of studies from PubMed and Cochrane databases was started in May 2020 and was finalized by June 2020. Material & Methods: The eligibility criteria were based on two factors; that the study be written in English and published through a peer reviewed journal. Through the database search, total 673 studies were identified. After checking studies thoroughly at various steps, only 26 were included in this review. Results: 11 studies claimed the link between food label reading and intake of nutrients, while there were 10 studies that measured the consumer's purchase and food choices by their awareness level about food labels. Conclusion: This systematic review demonstrates nutrition education to be directly correlated with the food-related habits of people. Further research is required to get a clear vision about knowledge of nutritional labels and its effect on real life dietary choices.
