This study aimed to investigate whether there was any difference in eating pattern, abnormal eating behaviour, obesity and the number of food addiction symptoms according to food addiction presence. A total sample of 851 healthy subjects living in Ankara (n = 360 male, n = 491 female) aged 19–65 years were included in this cross-sectional survey. Data on demographic information, 24-hour dietary recalls, Yale Food Addiction Scale (YFAS), Eating Attitudes Test-26 (EAT-26), and anthropometric measurements were collected through face-to-face interviews. Overall, 11.4% of participants were identified as “food addicted” (F: 13.0%; M: 9.2%). Subjects meeting criteria for ‘food addiction' had higher body mass index (35.1% were obese and 3.1% were underweight), compared to subjects without food addiction (13.1% were obese and 10.2% were underweight) (p<0.05). Abnormal eating attitudes estimated with EAT-26 were determined as 45.5% in males, 37.5% in females and 40.2% in total, among subjects with food addiction. Daily energy, protein and fat intakes were significantly higher in food addicted females, compared to non-addicted females (p<0.05). Participants with food addiction reported significantly more problems with foods, which contain high amounts of fat and sugar, compared to the participants without food addiction. Food addiction behaviour should be considered as a part of efforts towards reducing food related problems involving obesity.

The use of the nutrition facts label has been associated with healthy eating behaviors for adults. However, the relationship between nutrition facts label use and overall diet quality is not well known in young adults, a vulnerable group that acquire lifelong eating behaviors during this period of life. This study aimed to assess if the use of information on the nutrition facts label is associated with a higher diet quality in young adults. In this cross-sectional study, 958 university students aged 18–34 years were recruited. Nutrition facts label use was recorded. Dietary intake was assessed using 24-h dietary recall. Healthy Eating Index-2005 (HEI-2005) scores were calculated. HEI-2005 score was significantly associated with using nutrition facts label (p < 0.001). The mean total HEI-2005 score was 60.7 ± 10.11, 62.4 ± 11.43 and 67.1 ± 12.23 respectively for never, sometimes and everytime users of nutrition facts label (p < 0.001). Sub-group scores of HEI-2005 for total fruits, whole fruits, total vegetables, whole grains, milk, oils, saturated fat, and calories from solid fat, alcohol and added sugar (SoFAAS) were significantly higher in regular nutrition facts label users (p < 0.05, for each). This study showed that young adults who regularly use the nutrition facts label have a higher diet quality.

Purpose This study aims to determine the effects of nutrition knowledge on the use of nutrition facts labels in emerging adults by defining the nutrition education status. Design/methodology/approach For this cross-sectional study, 919 young adults, aged 18–24 years, were recruited. Participants trained by dietetic professional at least 2 h per week during the period of at least one education period were considered as having nutrition education. Food label use, specific circumstances and different food products were recorded. The participants were also asked about their attitudes regarding food label use with a questionnaire including 15 products. Findings Nutrition facts label is mainly used when buying a product for the first time, a product of an unknown brand or comparing different companies’ similar products, regardless of nutrition education status. Participants with nutrition education had a higher nutrition facts label use and they use the score for specific food products including breakfast cereal (p = 0.003), snacks (p < 0.001), beverages (p = 0.004), ready to eat soups (p = 0.004) and diet products for special occasions (p < 0.001). Mean total score of attitudes regarding food label use for participants who had nutrition education was found as 58.9 ± 6.1 and who did not have nutrition education was found as 51.7 ± 9.2 (p < 0.01). Originality/value Nutrition education, which is related to the nutrition facts label use, would be especially useful in helping people for the selection of healthier foods. As habits acquired from childhood will last for a lifetime, more effective nutrition education programs and nutrition label reading education programs should be designed. The findings need to be considered for promoting nutrition facts label use by developing nutrition education.
