Nutritional labelling in restaurants : whose responsibility is it anyway?

To explore consumer attitudes towards the potential implementation of compulsory nutritional labelling on commercial restaurant menus in the UK. This research was approached from the perspective of the consumer with the intention of gaining an insight into personal attitudes towards nutritional labelling on commercial restaurant menus and three focus groups consisting of participants with distinctly differing approaches to eating outside the home were conducted. The research suggests that while some consumers might welcome the introduction of nutritional labelling it is context dependent and without an appropriate education the information provided may not be understood anyway. The issue of responsibility for public health is unresolved although some effort could be made to provide greater nutritional balance in menus. Following this research up with a quantitative investigation, the ideas presented could be verified with the opinions of a larger sample. For example, a study into the reactions to nutritionally labelled menus in various restaurant environments. Consumers would react differently to the information being presented in a fine-dining restaurant than they would in popular catering or fast food. The obstacles faced by restaurants to provide not only nutritional information, but attractive, nutritious food are significant. Prior to this research there were few, if any, studies into the effects of food labelling on consumer choice behaviour in the context of hospitality management

Nutrition transition era: how does nutritional balance of West Sumatra fishermen’s families perform?

The purpose of this study is to observe the nutritional balance of fisherman's families in the Mandeh area of West Sumatra, Indonesia, in terms of food diversity, a clean and healthy lifestyle, physical activity, and nutritional status during the nutritional transition period. The sample size was 119 fishermen's families from the Mandeh area who were chosen randomly. An interview method that included a questionnaire and anthropometric measurements was used as the data collection technique. The interaction trend of nutritional status with food diversity, a clean and healthy lifestyle, and physical activity was seen by Chi-square analysis. The results found a significant relationship between physical activity and the nutritional status of fishermen's families, with a p-value of 0.020. Meanwhile, there was no correlation between food diversity, a clean and healthy lifestyle, and nutritional status (p>0.05). Additionally, nutritional problems, particularly obesity and malnutrition cases in fishermen's families in the Mandeh area of West Sumatera during the nutritional transition period, require attention; for instance, increasing prevention strategies to maintain nutritional balance

Uncovering the nutritional landscape of food

Recent progresses in data-driven analysis methods, including network-based approaches, are revolutionizing many classical disciplines. These techniques can also be applied to food and nutrition, which must be studied to design healthy diets. Using nutritional information from over 1,000 raw foods, we systematically evaluated the nutrient composition of each food in regards to satisfying daily nutritional requirements. The nutrient balance of a food was quantified herein as nutritional fitness, using the food's frequency of occurrence in nutritionally adequate food combinations. Nutritional fitness offers prioritization of recommendable foods within a global network of foods, in which foods are connected based on the similarities of their nutrient compositions. We identified a number of key nutrients, such as choline and alpha-linolenic acid, whose levels in foods can critically affect the foods' nutritional fitness. Analogously, pairs of nutrients can have the same effect. In fact, two nutrients can impact the nutritional fitness synergistically, although the individual nutrients alone may not. This result, involving the tendency among nutrients to show correlations in their abundances across foods, implies a hidden layer of complexity when exploring for foods whose balance of nutrients within pairs holistically helps meet nutritional requirements. Interestingly, foods with high nutritional fitness successfully maintain this nutrient balance. This effect expands our scope to a diverse repertoire of nutrient-nutrient correlations, integrated under a common network framework that yields unexpected yet coherent associations between nutrients. Our nutrient-profiling approach combined with a network-based analysis provides a more unbiased, global view of the relationships between foods and nutrients, and can be extended towards nutritional policies, food marketing, and personalized nutrition.Comment: Supplementary material is available at the journal websit

'Language is the source of misunderstandings'–impact of terminology on public perceptions of health promotion messages

Background: The high level of premature death due to non-communicable diseases has been associated with unhealthful lifestyles, including poor diet. The effectiveness of public health strategies designed to promote health via messages focusing on food and diets depends largely on the perception of the messages by the public. The aim of this study was to explore public perceptions of language commonly used to communicate concepts linking health, food and the diet.<p></p> Methods: This study is a qualitative and semi-quantitative cross-sectional survey exploring public perceptions of terms used to improve eating habits within public health strategies. We recruited adults with no background in nutrition or health-care, from May to July 2013, from urban areas of varying deprivation (n = 12) in Glasgow and Edinburgh, UK. Four key prompt-terms used to convey the idea of improving health through diet were selected for testing: Healthy Eating, Eating for Health, Balanced Diet and Nutritional Balance. Consumer understanding of these terms was explored using mixed-methods, including qualitative focus groups (n = 17) and an interviewer-led word-association exercise (n = 270).<p></p> Results: The word-association exercise produced 1,386 individual responses from the four prompt-terms, with 130 unique responses associated with a single term. Cluster analysis revealed 16 key themes, with responses affected by prompt-term used, age, gender and socio-economic status. Healthy Eating was associated with foods considered ‘healthy’ (p <0.05); Eating for Health and Balanced Diet with negative connotations of foods to avoid (both p <0.001) and Nutritional Balance with the benefits of eating healthily (p <0.01). Focus groups revealed clear differences in perceptions: Eating for Health = positive action one takes to manage existing medical conditions, Healthy Eating = passive aspirational term associated with weight management, Balanced Diet = old fashioned, also dieting for weight loss, Nutritional Balance = maximising physical performance. Food suppliers use Healthy Eating terminology to promote weight management products. Focus group participants welcomed product reformulation to enhance food health properties as a strategy to overcome desensitisation to health-messages.<p></p> Conclusions: Public perceptions of messages communicating concepts linking health, food and the diet are influenced by terminology, resulting in confusion. To increase individual commitment to change eating habits in the long term, public health campaigns need strengthening, potentially by investing in tailored approaches to meet the needs of defined groups of consumers

Awareness of Healthy Daily Nutrition Habits Among Adults

This research aimed to study the nutritional status of adults. The study concentrated on collecting information about the food habits and nutrition disturbances among adults. Questionnaire was used to collect data. The questionnaire composed of three parts; The first part was for personal information, while the second part concerned about nutrition disturbances and the disturbances. Nutrition habits diagnosed among the sample revealed different third part concerned about food intake. The results showed that the studied sample suffers from different nutritional imbalance food intake among the sample. Awareness of balance food program should be improved through educational nutrition programs. Keywords: Food intake, food disturbances, food habi

Case study of a female ocean racer: prerace preparation and nutritional intake during the Vendee Globe 2008.

The Vendée Globe is a solo round-the-world sailing race without stopovers or assistance, a physically demanding challenge for which appropriate nutrition should maintain energy balance and ensure optimum performance. This is an account of prerace nutritional preparation with a professional and experienced female racer and assessment of daily nutritional intake (NI) during the race using a multimethod approach. A daily energy intake (EI) of 15.1 MJ/day was recommended for the race and negotiated down by the racer to 12.7 MJ/day, with carbohydrate and fluid intake goals of 480 g/day and 3,020 ml/day, respectively. Throughout the 99-day voyage, daily NI was recorded using electronic food diaries and inventories piloted during training races. NI was assessed and a postrace interview and questionnaire were used to evaluate the intervention. Fat mass (FM) and fat-free mass (FFM) were assessed pre- (37 days) and postrace (11 days) using dual-energy X-ray absorptiometry, and body mass was measured before the racer stepped on the yacht and immediately postrace. Mean EI was 9.2 MJ/day (2.4-14.3 MJ/day), representing a negative energy balance of 3.5 MJ/day under the negotiated EI goal, evidenced by a 7.9-kg loss of body mass (FM -7.5 kg, FFM -0.4 kg) during the voyage, with consequent underconsumption of carbohydrate by ~130 g/day. According to the postrace yacht food inventory, self-reported EI was underreported by 7%. This intervention demonstrates the practicality of the NI approach and assessment, but the racer's nutrition strategy can be further improved to facilitate meeting more optimal NI goals for performance and health. It also shows that evaluation of NI is possible in this environment over prolonged periods, which can provide important information for optimizing nutritional strategies for ocean racing

Metabolic frailty in malnourished heart failure patients

Muscular wasting (MW) and cardiac cachexia (CC) are often present in patients with chronic heart failure (HF). Aim: To identify whether MW and CC are due to malnutrition or impairment of protein metabolism in HF patients. Material and Method: In 78 clinically stable HF patients (NYHA class II-III), aged from 32 to 89 years, we measured anthropometrical parameters and nutritional habits. In the identified 35 malnourished patients, we also measured: insulin resistance, gluconeogenetic amino acids blood concentration and nitrogen balance. Results: Seventy-five patients had eating-related symptoms. However we found significant nutritional impairment in 35 patients only. In addition, these 35 patients had: 1) significant increase of blood Alanine independently from both presence of insulin resistance or food intake reduction and 2) positive nitrogen balance. Conclusion: Food intake is not impaired in CHF patients. In spite of normal food intake, 35 of 78 patients had nutritional impairment with reduced anthropometric parameters and increased blood Alanine. These findings show alteration of proteins metabolism with proteolysis. We believe that specific physical training with nutritional supplement can be an additional therapy able to prevent protein disarrangement in CHF patients

DIETARY EVOLUTION OVER TIME IN EUROPE, BETWEEN CYCLOPS AND PHAECIANS . AN OUTLOOK ON THE ROLE OF SUPPLY-SIDE FACTORS IN DRIVING CHANGES IN THE FOOD PATTERNS

The present study intends to shed light, both from a descriptive and investigative point of view on the dietary evolution taking place in Europe during last 45 years, using secondary data from FAO FBS, which can cover the entire time span considered and allow for several extrapolation and timeseries analysis, differently than single survey data.. After a clustering of selected european national diets, using specific metrics with respect both to internal and external variety (as measured by appropriate indicators), we intended to check the actual distance that average, national diets have in front of the so called Food Pyramid, which consists in a balance of several food items in adequate proportions and in fact glorifies the healthy virtues of the Mediterranean Diet as a reference model among food patterns. Furthermore, if several studies focussed strictly on the evolution of diet per-se, from a nutritional perspective- our purpose was to put it in context with economic and materialistic factors which could have a part in the explanation. In particular, our intention was to provide a focus on trade factor as explaining the changing diets. We tested with causality tests the hypothesis behind, in order to find relationship between economic factors and nutritional aspects. Eventually, we propose a preliminary investigation about the role of GIs (Geographic Indication food products, such as PDO) in relation to globalised food patterns. The results are interesting, and let the doors open for interpretations and further research.diets, evolution, clustering, food pyramid, Europe, trade, GI, Agricultural and Food Policy, Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Health Economics and Policy, E37, Q18,

Between health and pleasure: perceptions of patients with cardiovascular disease following a nutritional intervention

The Brazilian Cardioprotective Nutritional Program (Balance)(f) consists of a nutritional counseling strategy aiming to prevent new cardiovascular events. This qualitative investigation is a case study of Balance aiming to understand the process of food choices related to the adherence of participants to the nutritional counseling. Semi-structured interviews were conducted with 10 participants and analyzed according to thematic content analysis. Patients reported incorporating nutritional advice and how they negotiate food choices to achieve a healthy diet while maintaining the consumption of pleasurable foods, some of them recommended avoiding. The continuous tensions and conflicts between healthy and pleasurable eating which permeate patients’ food choices should be addressed in nutritional counseling, enabling greater and long-lasting adherence to Balance

The determination of nutritional requirements for Safe Haven Food Supply System (emergency/survival foods)

The Space Station Safe Haven Food System must sustain 8 crew members under emergency conditions for 45 days. Emergency Survival Foods are defined as a nutritionally balanced collection of high density food and beverages selected to provide for the survival of Space Station flight crews in contingency situations. Since storage volume is limited, the foods should be highly concentrated. A careful study of different research findings regarding starvation and calorie restricted diets indicates that a minimum nutritional need close to RDA is an important factor for sustaining an individual's life in a stressful environment. Fat, protein, and carbohydrates are 3 energy producing nutrients which play a vital role in the growth and maintenance process of human life. A lower intake of protein can minimize the water intake, but it causes a negative nitrogen balance and a lower performance level. Other macro and micro nutrients are also required for nutritional interrelationships to metabolize the other 3 nutrients to their optimum level. The various options for longer duration than 45 days are under investigation
