The Impact of the Nutritional Knowledge of Polish Students Living Outside the Family Home on Consumer Behavior and Food Waste.

Food waste remains a major problem for the world and food security. Despite the fact that consumers are significant producers of food waste, little research attention has been paid to young people who are in college and living away from the family home. The present study aimed to assess food waste among college students living away from the family home, taking into account the nutritional knowledge acquired during college. In addition, the goal was to compare how nutritional knowledge affects food waste and consumer behavior in the study group. Descriptive statistics were performed on behaviors with food management at home, as well as shopping planning and self-shopping at the store, for the total respondents, students with nutritional knowledge and students without such knowledge. A chi-square test was performed to show whether the field of study influences the frequency of food throwing away and the appropriate management of excess food. Spearman's rank correlations were calculated for the frequency of food discarding, the frequency and amount of shopping and the field of study. The results indicate that the field of study determined food discarding and appropriate food management (p < 0.05), while it was found that fermented dairy beverages, fruits and vegetables and bread were the most frequently discarded foods in both study groups (p < 0.05). Students with nutritional knowledge were less likely to throw away food compared to students without nutritional knowledge and were better at managing excess food.

Diet Quality and Changes in Food Intake during the University Studies in Polish Female Young Adults: Linkages with Food Experiences from Childhood and Perceived Nutrition Concerns.

The transition from adolescence to young adulthood may be associated with unfavorable changes in food intake due to some substantial transformations in social life and environment. Factors that affect food choices and diet quality during early adulthood are still not well-recognized. This paper aims to explore the relationship between females' childhood food experiences related to parents' monitoring practices and healthy eating guidance, perceived nutrition concerns, changes in food intake during university studies, and diet quality. A cross-sectional study with the use of CAWI (Computer-Assisted Web Interview) was carried out on 657 female students aged 19-30 years. Beliefs and Eating Habits Questionnaire (KomPAN) was used to assess the frequency of eating various kinds of food and then to calculate the diet-quality index (DQI). Adults' Memories of Feeding in Childhood (AMoFiC) questionnaire was used to assess food experiences from childhood, and Health Concern Scale (HCS) was used to assess nutrition concerns. Associations between changes in food intake, diet quality, and selected factors describing the study sample were verified using logistic regression analysis. The DQI of the majority of students indicated a low intensity of nonhealthy and pro-healthy dietary characteristics. The intensity was higher among nutrition and health students, those with low nutrition concerns, and those with childhood experiences of monitoring. The chances of a negative change in food intake were increased by a higher score for childhood food experiences associated with parents' monitoring practices. The chances of a negative DQI were increased by bigger concerns about nutrition and by technical and agricultural majors; however, they were reduced by positive changes in food intake. Both childhood food experiences and perceived nutrition concerns should be factored into strategies aimed at improving youth diet and educating parents about effective parental feeding practices.

Consumer Motives for Choosing Fruit and Cereal Bars-Differences Due to Consumer Lifestyles, Attitudes toward the Product, and Expectations.

Fruit and cereal bars are the response to the changing needs of consumers seeking health-promoting and convenient products. A cross-sectional study was conducted using the CAWI (Computer-Assisted Web Interview) method, with 1034 respondents consuming products of this kind. The aims of the study were (1) to identify consumer segments based on the importance they attached to the selected attributes of fruit and cereal bars and (2) to characterize the identified segments in terms of frequency and reasons for the consumption of fruit and cereal bars, views on their impact on health, and consumer behavior related to the selected lifestyle elements. Five distinct consumer clusters were identified. Involved and Health-oriented were more likely to consume bars, perceiving them as nutritious products, with a positive impact on health. Frugal and Visual consumed fruit and cereal bars the least frequently. They paid little attention to choosing healthier products in daily diet and physical activity. The Information seekers consumed bars to reduce stress and to improve their mood.
