The study explores whether type 2 diabetes (T2D) diagnosis affects food consumption patterns in line with the dietary recommendations provided to individuals in relation to a diagnosis.

Based on detailed food purchase data, we explore which dietary changes are most common following a T2D diagnosis. Changes are investigated for several energy-adjusted nutrients and food groups and overall adherence to dietary guidelines.

We use data on diagnosis of T2D and hospitalisation in relation to T2D for a sample of adult Danes registered in the official patient register. This is combined with detailed scanner data on food purchases, which are used as a proxy for dietary intake.

We included 274 individuals in Denmark who are diagnosed during their participation in a consumer panel where they report their food purchases and 16 395 individuals who are not diagnosed.

Results suggest some changes in dietary composition following diagnosis, as measured by a Healthy Eating Index and for specific food groups and nutrients, although the long-term effects are limited. Socio-economic characteristics are poor predictors of dietary changes following diagnosis. Change in diet following diagnosis vary with the pre-diagnosis consumption patterns, where individuals with relatively unhealthy overall diets prior to diagnosis improve overall healthiness more compared to individuals with relatively healthy diets prior to diagnosis.

Adherence to dietary advice is low, on average, but there is large variation in behavioural change between the diagnosed individuals. Our results stress the difficulty for diagnosed individuals to shift dietary habits, particularly in the long term.

The current study aimed to assess Uruguayan consumers’ accounts of their own need to change their dietary patterns, their intended changes and the barriers related to doing so, and to compare the intentions and barriers with the recommendations of the national dietary guidelines.

An online survey with 2381 Uruguayan employed adults, aged between 18 and 65 years, 65 % females, was conducted. Participants had to answer two open-ended questions related to changes they could make in the foods they eat and/or the way in which they eat to improve the quality of their diet and the reasons why they had not implemented those changes yet. Content analysis using inductive coding by two researchers was used to analyse the responses.

Consumers mainly intended to change consumption of types of foods, particularly eating more fruits, vegetables and legumes and consuming less flour, but also intended to alter their eating patterns. Lack of time and the fact that healthy foods are perceived as being more expensive than unhealthy foods were major barriers to behaviour change. Some of the recommendations of the dietary guidelines, particularly those related to enjoying cooking and meals and engaging in it as a social activity, were not represented in consumer accounts.

Accompanying policies to the dietary guidelines need to underline the importance of changes in dietary patterns, including greater enjoyment and sharing food preparation and meals in the company with others, address misconceptions about flour, and provide concrete, consumer-derived recommendations on how to enact the guidelines.

The traditional Mediterranean diet includes high consumption of fruits, vegetables, olive oil, legumes, cereals and nuts, moderate to high intake of fish and dairy products, and low consumption of meat products. Intervention effects to improve adoption of this diet may vary in terms of individuals’ motivational or volitional prerequisites. In the context of a three-country research collaboration, intervention effects on these psychological constructs for increasing adoption of the Mediterranean diet were examined.

An intervention was conducted to improve Mediterranean diet consumption with a two-month follow-up. Linear multiple-level models examined which psychological constructs (outcome expectancies, planning, action control and stage of change) were associated with changes in diet scores.

Web-based intervention in Italy, Spain and Greece.

Adults (n 454; mean age 42·2 (sd 10·4) years, range 18–65 years; n 112 at follow-up).

Analyses yielded an overall increase in the Mediterranean diet scores. Moreover, there were interactions between time and all four psychological constructs on these changes. Participants with lower levels of baseline outcome expectancies, planning, action control and stage of change were found to show steeper slopes, thus greater behavioural adoption, than those who started out with higher levels.

The intervention produced overall improvements in Mediterranean diet consumption, with outcome expectancies, planning, action control and stage of change operating as moderators, indicating that those with lower motivational or volitional prerequisites gained more from the online intervention. Individual differences in participants’ readiness for change need to be taken into account to gauge who would benefit most from the given treatment.

To describe changes in consumption of different types of beverages from pre-pregnancy to early pregnancy, and to examine associations with maternal age, educational level and BMI.

Cross-sectional design. Participants answered an FFQ at inclusion into a randomized controlled trial, the Fit for Delivery (FFD) trial, in median gestational week 15 (range: 9–20), reporting current consumption and in retrospect how often they drank the different beverages pre-pregnancy.

Eight local antenatal clinics in southern Norway from September 2009 to February 2013.

Five hundred and seventy-five healthy pregnant nulliparous women.

Pre-pregnancy, 27 % reported drinking alcohol at least once weekly, compared with none in early pregnancy (P<0·001). The percentage of women drinking coffee (38 % v. 10 %, P<0·001), sugar-sweetened beverages (10 % v. 6 %, P=0·011) and artificially sweetened beverages (12 % v. 9 %, P=0·001) at least daily decreased significantly from pre-pregnancy to early pregnancy, while the percentage of women who reported to drink water (85 % v. 92 %, P<0·001), fruit juice (14 % v. 20 %, P=0·001) and milk (37 % v. 42 %, P=0·001) at least daily increased significantly. From pre-pregnancy to early pregnancy higher educated women reduced their consumption frequency of coffee significantly more than women with lower education. Older women reduced their consumption frequency of coffee and artificially sweetened beverages and increased their consumption frequency of fruit juice and milk significantly more than younger women.

There is a significant change in beverage consumption from pre-pregnancy to early pregnancy among Norwegian nulliparous women.

Between 1980 and 2008, two Pacific island nations – Nauru and the Cook Islands – experienced the fastest rates of increasing BMI in the world. Rates were over four times higher than the mean global BMI increase. The aim of the present paper is to examine why these populations have been so prone to obesity increases in recent times.

Three explanatory frames that apply to both countries are presented: (i) geographic isolation and genetic predisposition; (ii) small population and low food production capacity; and (iii) social change under colonial influence. These are compared with social changes documented by anthropologists during the colonial and post-colonial periods.

Nauru and the Cook Islands.

While islands are isolated, islanders are interconnected. Similarly, islands are small, but land use is socially determined. While obesity affects individuals, islanders are interdependent. New social values, which were rapidly propagated through institutions such as the colonial system of education and the cash economy, are today reflected in all aspects of islander life, including diet. Such historical social changes may predispose societies to obesity.

Colonial processes may have put in place the conditions for subsequent rapidly escalating obesity. Of the three frameworks discussed, social change under colonial influence is not immutable to further change in the future and could take place rapidly. In theorising obesity emergence in the Pacific islands, there is a need to incorporate the idea of obesity being a product of interdependence and interconnectedness, rather than independence and individual choice.

To investigate maintenance of changes in food intake and motivation for healthy eating at follow-up 2 data collection after a lifestyle intervention among Pakistani immigrant women.

A culturally adapted lifestyle intervention, aiming at reducing the risk of type 2 diabetes mellitus. Data collection including FFQ and questions on intentions to change dietary behaviour was completed at baseline, right after the 7 ± 1 month intervention (follow-up 1) and 2–3 years after baseline (follow-up 2).

Oslo, Norway.

Pakistani women (n 198), aged 25–60 years, randomized into control and intervention groups.

From follow-up 1 to follow-up 2 there was a shift from action to maintenance stages for intention to reduce fat intake (P < 0·001), change type of fat (P = 0·001), increase vegetable intake (P < 0·001) and reduce sugar intake (P = 0·003) in the intervention group. The reduction in intakes of soft drinks with sugar, fruit drinks with sugar and red meats, and the increase in intakes of vegetables and fish from baseline to follow-up 1 were maintained (significant change from baseline) at follow-up 2 in the intervention group. The intake of vegetables was higher (P = 0·019) and the intake of fruit drinks with sugar lower (P = 0·023) in the intervention group compared with the control group at follow-up 2.

The culturally adapted intervention had the potential of affecting intentions to change food behaviour among Pakistani immigrant women long after completion of the intervention and also of leading to long-term maintenance of beneficial changes in diet.

The main purpose of the study was to investigate the feasibility of using workplaces to increase the fruit consumption of participants by increasing fruit availability and accessibility by a minimal fruit programme. Furthermore, it was investigated whether a potential increase in fruit intake would affect vegetable, total energy and nutrient intake.

A 5-month, controlled, workplace study where workplaces were divided into an intervention group (IG) and a control group (CG). At least one piece of free fruit was available per person per day in the IG. Total fruit and dietary intake was assessed, using two 24 h dietary recalls at baseline and at endpoint.

Eight Danish workplaces were enrolled in the study. Five workplaces were in the IG and three were in the CG.

One hundred and twenty-four (IG, n 68; CG, n 56) healthy, mainly normal-weight participants were recruited.

Mean daily fruit intake increased significantly from baseline to endpoint only in the IG by 112(se 35) g. In the IG, mean daily intake of added sugar decreased significantly by 10·7(se 4·4) g, whereas mean daily intake of dietary fibre increased significantly by 3·0(se 1·1) g. Vegetable, total energy and macronutrient intake remained unchanged through the intervention period for both groups.

The present study showed that it is feasible to increase the average fruit intake at workplaces by simply increasing fruit availability and accessibility. Increased fruit intake possibly substituted intake of foods containing added sugar. In this study population the increased fruit intake did not affect total energy intake.

For effective healthy eating promotion, it is necessary to understand the attitudes towards and beliefs about nutrition of the general public. The objective of this study was to provide data on attitudes towards eating a healthy diet and the perceived need to alter eating habits from a random sample of adults in the Republic of Ireland and in Northern Ireland, using a self-administered questionnaire.

Cross-sectional survey using a self-administered attitudinal questionnaire on beliefs and attitudes to healthy eating.

The survey was carried out between October 1997 and October 1999 in the Republic of Ireland and in Northern Ireland.

A randomly selected sample of 1256 adults from the Republic of Ireland and Northern Ireland completed the attitudinal questionnaire.

A majority of subjects (62%) perceived that they make conscious efforts to eat a healthy diet either most of the time or quite often, while just over half (52%) agreed that they do not need to make changes to their diet as it is healthy enough. Subjects most likely to make conscious efforts to try to eat a healthy diet were females, older subjects (51-64 years) and those with the highest intakes of fruit and vegetables and lowest quartile of fat (% food energy). When self-assessed adequacy of fruit and vegetables was examined, two-thirds of the total sample felt they ate too little fruit while just one-third felt they ate too little vegetables.

Results of the present study, in general, revealed good agreement between attitude and behaviour with respect to healthy eating. This suggests that people appear to be reasonably accurate at evaluating their own diet in terms of how healthy it is. In terms of the two food groups examined in this study, some optimistic bias was evident for vegetables but not for fruit. It may be useful therefore to assess attitudes and beliefs about healthy eating by way of examining attitudes to such food groups individually.

To describe scales that measure motivations for changing dietary behaviour, and to examine associations of these scales with current diet and dietary change.

A secondary analysis of a randomised trial of a self-help intervention to promote lower fat and higher fruit and vegetable consumption.

Participants and setting: Participants were 1205 adults selected at random from enrolees of a large Health Maintenance Organization. At baseline, data were collected on motives for changing diet, fruit and vegetable intake, fat-related dietary habits, and demographic characteristics. Participants were then randomised to receive the intervention or to receive no materials. A follow-up survey was administered at 12 months.

A majority of participants reported that it was very important to make dietary changes to feel better (72%) and to control an existing medical problem (57%), but very few (4%) were motivated by pressure from others. Factor analysis of the diet motivation items yielded two intrinsic (‘self-image’ and ‘personal health’) and one extrinsic (‘social pressure’) scales with fair internal consistency reliabilities (Cronbach's α = 0.59 to 0.68). Motivation scales were statistically significantly associated with demographic characteristics and baseline diet. For example, desire for a better self-image was a stronger motivator for changing diet among females, while personal health was more important to older persons and men (P < 0.001). Social pressure to change diet was statistically significantly associated with higher fat intake (r = 0.11) and self-image was associated with lower fat intake (r = −0.14, both P < 0.001). Motivation by social pressure and self-image were both significantly associated with greater fat reduction at 12 months post-intervention (P < 0.05).

The intrinsic and extrinsic motivation scales were weakly associated with current diet and predicted response to dietary intervention. More research is needed to better characterise and measure motives for dietary change, and to test whether tailoring interventions based on individuals' motives for dietary change would improve intervention effectiveness.

This paper explores the unique nutrition transition shifts in diet and activity patterns from the period termed the receding famine pattern to the one dominated by nutrition-related non-communicable diseases (NR-NCDs). The paper examines the speed and timing of these changes; unique components, such as the issue of finding both under- and overnutrition in the same household; potential exacerbating biological relationships that contribute to differences in the rates of changes; and political issues.

The focus is on lower-and middle-income countries of Asia, Africa, the Middle East and Latin America.

These changes are occurring at great speed and at earlier stages of these countries economic and social development. There are some unique issues that relate to body composition and potential genetic factors. The significance of the high number of persons exposed to heavy insults during pregnancy and infancy (foetalorigins hypothesis) and the subsequent rapid shifts in energy imbalance remains to be understood. Countries that are still addressing major concerns of undernutrition are not ready to address these NR-NCDs.

The developing world needs to give far greater emphasis to addressing the prevention of the adverse health consequences of this shift to the nutrition transition stage of degenerative diseases.
