Food literacy: Definitions, components, learning and links to diet and health outcomes

Recently, the term ‘food literacy’ has emerged in policy, research and practice to describe the collection of knowledge, skills and behaviours required to practically meet food needs. This presentation will described research undertaken to empirically define the term and propose its impact on nutrition

Condition-specific associations of symptoms of depression and anxiety in adolescents and young adults with asthma and food allergy

Objective: This study examined associations of asthma and food allergy with symptoms of depression and anxiety at 14 and 21 years of age to determine whether condition-specific associations exist. Methods: Data come from 4972 adolescents in the Mater University Study of Pregnancy. Symptoms of depression and anxiety were assessed using the Youth Self-Report and Young Adult Self-Report. Results: Condition-specific associations between asthma and depression, OR=1.37 [1.12, 1.67] and between food allergy and anxiety, OR=1.26 [1.04, 1.76] were found during adolescence, but not in young adulthood. Whereas asthma was associated with resolved depression, OR=1.70 [1.13, 2.55], food allergy was associated with persistent anxiety, OR=1.26 [1.01, 1.59]. Conclusions: In adolescents, asthma is associated with an increased risk of clinically relevant symptoms of depression and food allergy with and increased risk of clinically relevant symptoms of anxiety. Future research is needed to clarify directionality and mechanisms explaining these relationships. Health professionals should be aware of the increased risk of mental health problems in adolescents with asthma or food allergy.

Where have all the zebras gone? The pedestrian ranks lowest in the food chain of Kathmandu's urban jungle

This article presents an overview of pedestrian environment in Kathmandu, Nepal to briefly discuss some of the emerging problems. It argues that pedestrian ranks lowest in the food chain of Kathmandu's urban jungle as there is too little concern shown by the government agencies in improving the quality of the street space for walkers.

Clinical tips: Food poisoning

Food poisoning is used to describe a range of illnesses caused by drinking or eating contaminated drink or food. Infectious pathogens include bacteria, viruses, parasites, or their toxins, though food poisoning can also be a result of eating poisonous plants e.g. some mushrooms, or animals e.g. puffer fish. Common symptoms include nausea, vomiting, watery diarrhoea, abdominal pain and cramps, and fevers, though these will vary depending on the causative pathogen or toxin. Symptoms can start within hours of eating contaminated food, or may begin days or weeks later. Most food poisoning is mild in nature, lasts for several hours to a few days, and generally resolves without treatment. However, some cases of food poisoning can also be extremely severe, with people requiring medical attention or admission to hospital...

Taste over waste: Ugly food movement winning friends

Consumer driven food trends are nothing new. “Organics”, gluten-free, and more recently buying “local” have all captured consumers, encouraging supermarkets around the globe and in Australia to respond. But the next emerging European food trend that may have the biggest impact on what we buy each week is “ugly food”.

Biofuels from food processing wastes

Food processing industry generates substantial high organic wastes along with high energy uses. The recovery of food processing wastes as renewable energy sources represents a sustainable option for the substitution of fossil energy, contributing to the transition of food sector towards a low-carbon economy. This article reviews the latest research progress on biofuel production using food processing wastes. While extensive work on laboratory and pilot-scale biosystems for energy production has been reported, this work presents a review of advances in metabolic pathways, key technical issues and bioengineering outcomes in biofuel production from food processing wastes. Research challenges and further prospects associated with the knowledge advances and technology development of biofuel production are discussed.

What do prisoners eat? Nutrient intakes and food practices in a high secure prison

There are limited studies on the adequacy of prisoner diet and food practices, yet understanding these are important to inform food provision and assure duty of care for this group. The aim of this research was to assess the dietary intakes of prisoners to inform food and nutrition policy in this setting. This research used a cross-sectional design with convenience sampling in a 945 bed male high secure prison. Multiple methods were used to assess food available at the group level, including verification of food portion, quality, and practices. A pictorial tool supported the diet history method. Of 276 eligible prisoners, 120 dietary interviews were conducted and verified against prison records, with 106 deemed plausible. The results showed the planned food to be nutritionally adequate, with the exception of vitamin D for older males and long chain fatty acids, with sodium above Upper Limits. The Australian Dietary Targets for chronic disease risk were not achieved. High energy intakes were reported with median 13.8MJ (SE 0.3MJ). Probability estimates of inadequate intake varied with age groups: magnesium 8% (>30 years), 2.9% (<30 years); calcium 6.0% (>70 years), 1.5% (<70 years); folate 3.5%; zinc and iodine 2.7%; and vitamin A 2.3%. Nutrient intakes were greatly impacted by self-funded snacks. Results suggest nutrient intakes nutritionally favourable when compared to males in the community. This study highlights the complexity of food provision in the prison environment, and also poses questions for population level dietary guidance in delivering appropriate nutrients within energy limits.

Improving food supply

Improving the availability, accessibility and affordability of healthy food equitably is fundamental to improving nutrition and health. While theoretical models abound, in real world complex systems rarely are there opportunities to address leverage points systematically to improve food supply. This presentation describes efforts over the last 30 years to do just that by remote Australian Aboriginal communities, where a single community store is usually the major dietary source. Areas addressed include store governance and infrastructure, wholesale supply, transport and pricing policies including cross-subsidization. However, while there have been dramatic improvements in the availability, quality and price of fruit, vegetables and most other healthy foods over this time, the proportion of communities' energy intake from energy-dense nutrient-poor foods and drinks has increased. One cause may be the disproportionate increase in supply of unhealthy choices in terms of variety and shelf-space, consistent with changes in the food supply in broader Australia. The impact of changing social and environmental factors, food preferences and price elasticity will also be explored briefly. Clearly much more needs to be done to reduce the high prevalence of diet-related chronic disease in some vulnerable groups. In particular, efforts to continually improve the availability and affordability of healthy food also need to address the predominance of unhealthy choices in the food supply.
