Purpose – The purpose of this paper is to determine the volume and quality of food waste in Finnish households and discuss drivers for waste being produced. Design/methodology/approach – In total, 380 households weighed all solid food waste and liquid milk waste daily each time they disposed food during a two-week period. The authors concentrated only on avoidable food waste, i.e. all wasted food and raw material that could have been consumed, had they been stored or prepared differently. Other biowaste, such as vegetable peelings, coffee grounds, or bones, was not measured. Findings – The amount of food waste in households ranged from 0 to 160 kg/year. The average annual food waste was 23 kg per capita, 63 kg per household, and in total about 120 million kg/year. When comparing purchased food amount with avoidable food waste, the average waste was about 4-5 per cent. The main discarded foodstuffs were vegetables, home-cooked food and milk products. The principal reasons for disposing of foodstuffs were spoilage: e.g. mould, expiry of best before or use by date, plate leftovers, and preparing more food than needed. When examining waste per person, singles generally produced most waste. Practical implications – Knowledge about food waste will help development of new practices to decrease waste. Originality/value – The study estimated amounts of food waste in households using diaries and weighing. Such studies have often been based on statistics or interviews rather than exact weighing of waste.

Purpose The purpose of this paper is to explore reasons for household preparation losses. Design/methodology/approach Observations of preparation behaviors and semi-structured interviews of nine people were conducted in their kitchens. The data were analyzed through a qualitative data analysis method. Findings Three types of preparation losses were identified, i.e. possibly avoidable food waste, excessive removals and unintentional losses. Possibly avoidable food waste and excessive removals were generated owing to people’s perception that is in the gray area between edible and inedible, their preferences, lower quality of food, convenience in preparation, lack of preparation skill and knowledge, and lack of concern about preparation losses. Unintentional losses were tiny pieces of food that were left on cooking tools. Research limitations/implications As this study’s participants were nine women living in Japan, further research is needed in order to achieve saturation. Originality/value Few studies have discussed reasons for preparation losses, and extant studies were based on a diary method and questionnaires. This present study uncovers several new reasons for preparation losses based on interviews and observations of consumer preparation behaviors. These new details would be helpful for campaigns or programs that aim to reduce food losses.

Purpose Food waste behavior in the workplace or work-related gatherings has been less researched compared to that in household context. This study aims to bridge this gap through unfolding how and when quality of food waste prevention communication mitigates food waste behavior among frontline employees in the hospitality workplace. Design/methodology/approach Participants in this research comprised employees from four- and five-star hotels operating in Vietnam. Findings The results lent credence to the dual mediation channels of moral attitudes toward food wasting and meaningfulness of food waste reduction for the impact of quality of food waste prevention communication on employees’ food waste reduction intention and their reduced food waste behavior. The contingency role of employees’ green role identity was marginally confirmed for the nexus between employees’ food waste reduction intention and their food waste behavior. Originality/value This inquiry advances the understanding of mechanisms underlying work-related food waste behavior among hospitality employees.

«Man is what he eats,» these words belong to the great Pythagoras. He meant by these words the connection of the origin of consumed food with the spiritual development of man. In fact, a lot depends on the nature of nutrition, the quality of food and, of course, on the degree of its perception by the body. Digestion process begins not in the stomach, but directly in the oral cavity as a result of mechanical processing of products with teeth and under the influence of the secretion of the salivary glands. That is why healthy teeth are the key to the normal functioning of the whole organism — people should start taking care of their teeth from the early childhood and dentists, who are far from being beloved by everybody and are often carelessly evaded, are called upon to help keep the teeth healthy.

Background: Bacterial counts in ready-to-eat foods are a key factor in assessing the microbiological quality and safety of food. Periodic assessment of the microbiological quality of food is necessary to develop a robust database and help to ensure food safety. </P><P> Methods: The bacterial contamination of a total of 336 bread samples collected from two bakeries and 10 vendors in Ojoo Area of Ibadan, Oyo-State, Nigeria (December 2014 -June 2015) was evaluated. The microbiological quality of the bread loaves was investigated using standard microbiological methods (morphological, phenotypic and molecular characterization). </P><P> Results: The results showed that the number of contaminated samples among the vended bread samples was higher than the bakery bread samples and can be summarized as Bacillus megaterium (4.30%), Staphylococcus arlettae (0.005%), Staphylococcus saprophyticus (2.78%), Citrobacter freundii (2.40%), Bacillus flexus (1.64%), Bacillus species (49.59%), Pseudomonas aeruginosa (4.12%), Pseudomonas fluorescens (0.92%), Pseudomonas species (0.045%), Escherichia coli (30.44%) Klebsiella sp. (0.040%) and Aeromonas hydrophila (3.72%). </P><P> Conclusion: The findings demonstrate that the bread samples which become contaminated after transport and handling can be considered a potential hazard to human health in the area. More stringent adherence to food safety regulations should be encouraged and enforced by the appropriate authorities. The findings of this study may be adopted to improve the hygienic conditions of bread distribution chain in the area as well as in other regions of the World.

We are in technical era where there is more of sedentary life style and stress along with this urbanization is affecting our quality of food and health. This is leading to many lifestyle disorders and hormonal imbalances in our body. Hypothyroidism one among the endocrinal disorder. Thyroid is an endocrinal gland secrets T3 and T4 hormones regulated by TSH which is secreted by Pituitary gland. These hormones have two major effects on the body, 1) To increase the overall metabolic rate in the body 2) To stimulate growth in children. Hypothyroidism is common health issue in India. The highest prevalence of hypothyroidism (13.1%) is noted in people aged 46-54yrs old. With people aged 18-35 yrs being less affected (7.5%). To prevent these hazards Panchakarma is beneficiary to maintain metabolic rate. Here an attempt is made to diagnose hypothyroidism in the light of Ayurveda and management guidelines through Panchakarma.

This chapter examines the impact of rapid urbanization and industrialization on food and eating out. It draws attention to the growing standardization of food and, with greater class differentiation, to the growing diversity in eating-out venues. Class, gender, and nation are again used as lenses to understand the different eating-out habits and their symbolic significance. Towards the end of the twentieth century, pubs moved more fully towards embracing dining. However, the quality of food, in general terms, began to improve significantly only towards the end of the century, and hospitality venues also moved towards selling food from diverse national origins.
