Is it gluten-free? Relationship between self-reported gluten-free diet adherence and knowledge of gluten content of foods.

OBJECTIVE:
To assess the relationship between self-reported adherence to a gluten-free diet (GFD) and the ability to determine correctly the appropriateness of particular foods in a GFD.

METHODS:
Persons with celiac disease were recruited through clinics and support groups. Participants completed a questionnaire with items related to GFD information sources, gluten content of 17 common foods (food to avoid, food allowed, and food to question), GFD adherence, and demographic characteristics. Diagnosis was self-reported.

Eating like there's no tomorrow: public awareness of the environmental impact of food and reluctance to eating less meat as part of a sustainable diet.

Reducing meat consumption is central to many of the scientific debate on healthy, sustainable diets because of the high environmental impact of meat production. Missing from this debate, however, is the public perspectives about eating less meat and consideration of cultural and social values associated with meat. The aim of this study was to explore public awareness of the environmental impact of food and their willingness to reduce meat consumption.

The importance of habits in eating behaviour. An overview and recommendations for future research.

There is ample evidence to suggest that a significant part of daily eating behaviours consists of habits. In line with this, the concept of habit is increasingly incorporated into studies investigating the behavioural and psychosocial determinants of food choice, yielding evidence that habit is one of the most powerful predictors of eating behaviour.

Vegetarian nutrition: past, present, future.

Early human food cultures were plant-based. Major religions such as Hinduism and Buddhism have recommended a vegetarian way of life since their conception. The recorded history of vegetarian nutrition started in the sixth century bc by followers of the Orphic mysteries. The Greek philosopher Pythagoras is considered the father of ethical vegetarianism. The Pythagorean way of life was followed by a number of important personalities and influenced vegetarian nutrition until the 19th century. In Europe, vegetarian nutrition more or less disappeared during the Middle Ages.

Meat, beyond the plate. Data-driven hypotheses for understanding consumer willingness to adopt a more plant-based diet.

A shift towards reduced meat consumption and a more plant-based diet is endorsed to promote sustainability, improve public health, and minimize animal suffering. However, large segments of consumers do not seem willing to make such transition. While it may take a profound societal change to achieve significant progresses on this regard, there have been limited attempts to understand the psychosocial processes that may hinder or facilitate this shift.

Investigation of lifestyle choices of individuals following a vegan diet for health and ethical reasons.

The proportion of individuals choosing to follow a vegan diet has increased in recent years. The choice is made for different reasons, primarily concern for animals (ethics) and health, which may impact both specific food choices and other lifestyle behaviors linked to health outcomes. To determine the extent to which the reason for following a vegan diet was associated with health behaviors, we conducted an online survey recruiting an international sample of 246 individuals who reported adhering to a vegan diet.
