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.

CVD remains the major cause of death for dialysis patients. Dialysis patients have both traditional and nontraditional risk factors, including the retention of advanced glycation end products (AGE). Tissue AGE can be measured by skin autofluorescence (SAF) and are a reliable measurement of chronic exposure. Dietary intake of AGE may be lower in vegetarian patients than in non-vegetarian patients, so we determined whether vegetarian patients had lower SAF than non-vegetarian patients. We measured SAF in 332 adult haemodialysis patients using a UV technique in a standardised manner.

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.

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.
