Modelling of avoidance of food additives: a cross country study

Chemical Contamination Pathways and the Food Safety Implications along the Various Stages of Food Production: A Review

Historically, chemicals exceeding maximum allowable exposure levels have been disastrous to underdeveloped countries. The global food industry is primarily affected by toxic chemical substances because of natural and anthropogenic factors. Food safety is therefore threatened due to contamination by chemicals throughout the various stages of food production. Persistent Organic Pollutants (POPs) in the form of pesticides and other chemical substances such as Polychlorinated Biphenyls (PCBs) have a widely documented negative impact due to their long-lasting effect on the environment. This present review focuses on the chemical contamination pathways along the various stages of food production until the food reaches the consumer. The contamination of food can stem from various sources such as the agricultural sector and pollution from industrialized regions through the air, water, and soil. Therefore, it is imperative to control the application of chemicals during food packaging, the application of pesticides, and antibiotics in the food industry to prevent undesired residues on foodstuffs. Ultimately, the protection of consumers from food-related chemical toxicity depends on stringent efforts from regulatory authorities both in developed and underdeveloped nations.

Knowledge about Sugar Sources and Sugar Intake Guidelines in Portuguese Consumers

In this work, we examined knowledge about sugars and guidelines for its consumption and explored the relationship between knowledge and measures related to nutritional information processing as well as sugar consumption. Specifically, we asked participants (n = 1010 Portuguese) to categorize a set of ingredients (e.g., glucose, aspartame) regarding their composition (i.e., intrinsic vs. added/free sugars) and origin (e.g., natural vs. artificial) and if they were aware of the WHO guidelines for sugar intake. Overall, despite using information about sugar frequently and considering attending to such information as very important to stay healthy, most participants were unaware of the WHO guidelines and revealed difficulties in the categorization task. Women, participants with a higher level of education, and those with children in the household reported higher use of sugar content information present in nutritional labels, higher perceived knowledge of nutritional guidelines, and higher hit rates in categorizing sugar sources. Almost one-fourth of the population exceeds the daily limit recommended by the WHO. Therefore, characterizing the knowledge of a Portuguese sample regarding sugar sources and sugar intake guidelines is particularly relevant, and our results emphasize the need to implement effective strategies to reduce sugar intake.

Knowledge and acceptance of interventions aimed at reducing sugar intake in Portugal

OBJECTIVE

Governments worldwide have been implementing interventions aimed at improving citizens' dietary habits. Examining how individuals perceive these interventions is relevant for promoting future policies in this area, as well as informing the way they are designed and implemented. In the current study, we focused on interventions aimed at reducing sugar intake in Portugal, given the current high sugar consumption patterns in the population.

DESIGN

Online survey to assess which interventions are the most salient and receive greater public support.

SETTING

Portugal.

PARTICIPANTS

1010 (76·7 % female, MAge 36·33, sd 13·22).

RESULTS

Data from a free-recall task showed that only about one-third of participants reported knowing about these interventions, namely those related to taxation, weight restrictions in individual sugar packets and limited availability of products with high sugar content. We also found evidence of high support for the eight interventions presented (except for replacing sugar by artificial sweeteners), positive attitudes towards the need of reducing sugar intake in the Portuguese population and high agreement with the importance of reducing sugar intake across all age groups, particularly among children. Participants also indicated paying attention to the amount of sugar in their diets and a low self-reported frequency of consumption of high sugary foods and beverages. A hierarchical regression analysis suggested that these variables were significantly associated with the overall acceptance of interventions, independently of social-demographic variables (i.e., age, education and sex).

CONCLUSION

By examining how people perceive and accept different interventions targeting the reduction of sugar intake, the current work aims to support policymaking in this domain.
