“…However, we observed 62% of students listed vitamins, as this is the most indicated nutrient. The data is compatible with Enochson & Redfors (2012) studies, where students refer to vitamins as their first option when they have to name nutrients.…”

“…Students who made mistakes pointed calcium, zinc and carbohydrates as vitamins with higher frequencies; however, some answers also included fibers, phosphorus and sodium. Among vitamin C, vitamin B2 and vitamin B6, found in nutrition facts tables A and B, the most listed was vitamin C. We relate this result to the facts presented by Enochson & Redfors (2012), since the authors relate social aspects to vitamins, emphasizing how media can disclosure information related to the benefits of vitamins; in addition, according to Santos & Barros Filho (2002), people relate vitamin C to the prevention of cold and flu.…”

The study was undertaken to investigate the conceptions of Brazilian Basic Education (Elementary and High School) Students about food nutrients, food pyramids, processed food labels and nutrition facts tables. The research involved groups from sixth to ninth grades of Elementary School and first to third grades of High School in a public school from Paraná State, Brazil. In this study, 257 students, aged 11-17 years old, took part. For the identification of conceptions, group activities were performed using food pyramids, processed food labels and nutrition facts tables, aiming the analysis of their nutritional composition by students. Analysis showed students do not show satisfactory and coherent conceptions about food nutrients, and many students were not able to distinguish nutrients from food. In this sense, we highlight the need of Food Nutrition programs to endorse and include initiatives for students, regarding the positive comprehension of nutrients and their benefits to the body, besides healthy eating habits.

In this paper we focus on how South African students' ideas about the human body are constituted in their descriptions of three different scenarios involving the pathway of a sandwich, a painkiller and a glass of water through the body. In particular, we have studied the way in which the students transferred ideas between the sandwich and the painkiller compared with the students' ability to explain the water pathway. The study surveyed 161 ninth-grade students in five different schools in South Africa. Data collection methods used were: drawings, written questions (open-ended items) and interviews with selected students. The questions emerged from the three scenarios-what happens in the body when you eat a sandwich, swallow a painkiller and drink a glass of water. We report that it is difficult for the students to transfer knowledge of the digestive system horizontally from the sandwich scenario to descriptions of the painkiller and water scenarios. The integration of three organ systems (digestive, circulatory and excretory) to describe the water scenario was even more difficult for the students than the horizontal transfer from the sandwich scenario. The students also showed a diversity of nonscientific descriptions, especially concerning the water scenario. The paper discusses why a large percentage of the students (∼50%) included non-scientific ideas in their decriptions of the water scenario.
