Examining the "Veggie" personality: Results from a representative German sample.
2017
Abstract An increasing proportion of people choose to follow a vegetarian diet. To date, however, little is known about if and how individual differences in personality relate to following a vegetarian diet. In the two studies presented here, we aimed to (1) estimate the prevalence of self-defined vegetarians in two waves of a German representative sample (N = 4496 and 5125, respectively), (2) analyze the effect of socio-demographic variables on dietary behavior, and (3) examine individual differences between vegetarians and meat eaters in personality traits, political attitudes, and health-related variables. In Study 1, a strict definition of vegetarians was used, while in Study 2 the defi…
Nutrient intake of endurance runners with ovo-lacto-vegetarian diet and regular western diet
1994
During an endurance run (1,000 km in 20 days) it was investigated whether an ovo-lacto-vegetarian diet (OLVD) could cover the nutritional requirements of endurance athletes. A regular western diet (RWD) was used as reference. Both diets were offered with an energy content of 4,500 kcal per day and an energy percentage of carbohydrate:fat:protein of 60:30:10. The runners were divided into two dietary groups according to their usual dietary habits. The results of the 55 participants who completed the race show that runners from both groups had the same intake of energy, carbohydrate, fat and protein. Runners of the OLVD group consumed more dietary fiber and polyunsaturated fatty acids as well…
Aesthetics of Nutrition, Ethics of Animality: the Packaging of Vegan and Vegetarian Products in the Italian Organised Distribution Market
2018
The topic of this paper concerns the packaging of vegan and vegetarian products in the Italian organised distribution market. Large-scale organised distribution and vegetarianism's choice of packaging is related to current dietary trends which, as is often the case with eating choices and habits, intertwine as they massively spread. Which are the visual and verbal strategies that are adopted to give meaning, in the Italian culinary landscape, to vegan and vegetarian foods sold through large-scale distribution? The aim is to outline, through the methodology of Semiotics, the sensorial mechanisms and cultural grids that shape this food universe, and the way it interacts with other categories …
Adequate vitamin B12 and folate status of Norwegian vegans and vegetarians
2022
AbstractPlant-based diets may increase the risk of vitamin B12 deficiency due to limited intake of animal-source foods, while dietary folate increases when adhering to plant-based diets. In this cross-sectional study, we evaluated the B12 and folate status of Norwegian vegans and vegetarians using dietary B12 intake, B12 and folic acid supplement use, and biomarkers (serum B12 (B12), plasma total homocysteine (tHcy), plasma methylmalonic acid (MMA) and serum folate). Vegans (n 115) and vegetarians (n 90) completed a 24-h dietary recall and a FFQ and provided a non-fasting blood sample. cB12, a combined indicator for evaluation of B12 status, was calculated. B12 status was adequate in both v…
Dietary Conversions and Forms of Life
2019
This paper regards the emergence of forms of life in the field of food and dietary choices. It aims at connecting meat-free diets with the notion of form of life, especially focussing on the moment of “conversion” from an omnivourous diet to vegetarianism or veganism. The semiotic mechanisms of transitions between forms of life connected to dietary regimens will be highlighted. How does the conversion happen? Like in spiritual and religious discourses, the conversion is often a striking event, a punctual episode in the subject’s life, affecting particularly his/her pathemic and sensorial spheres. In other cases, conversions imply complex and slow processes, affecting pragmatic and cognitive…
Diet, authoritarianism, social dominance orientation, and predisposition to prejudice
2015
Purpose – The purpose of the paper is to examine whether reported food habits (vegan, vegetarian, or carnivore diet) are associated with right-wing authoritarianism, prejudices against minorities and acceptance of social dominance. Design/methodology/approach – In total, 1,381 individuals completed validated questionnaires on dietary habits and attitudes. Associations were analysed using analyses of covariance on attitudes, adjusted for age with gender and diet as factors. Findings – Of the respondents, 35 per cent reported eating mixed food (including meat and fish), 31 per cent vegetarian food (excluding meat and fish) and 34 per cent vegan food (excluding animal products entirely). Auth…
The effects of calorie restriction, intermittent fasting and vegetarian diets on bone health.
2019
Uncountable health care organizations, clinicians, and individuals are striving to prevent obesity and the many chronic medical conditions linked to it by advocating a healthy lifestyle that includes measures such as reducing dietary calorie intake (i.e., calorie restriction = CR and intermittent fasting = IF) or limiting/abolishing animal source foods (i.e., practices termed vegetarianism and veganism). Although these regimens are traditionally considered healthy, their real impact on bone health has yet to be established, and some studies have reported that they have negative effects on bone outcomes. The current work provides an overview of the studies carried out to examine the effect/s…
Do Body Composition and Values of Selected Nutritional Status Indices Influence the Glycaemic Index Values of Vegetarian Dishes? A Pilot Study in a G…
2022
An ageing population brings with it the need for public policy to respond to the demands and health needs of this group of people. The ageing process has been shown to be associated with changes in body composition. These mainly concern a decrease in muscle mass and an increase in body fat. Body composition and other indicators of nutritional status are important factors differentiating carbohydrate management. Glycaemic index (GI) values may be affected by differences resulting from individual metabolism. The rate of carbohydrate digestion is also influenced by a number of factors, including the degree to which the product is processed, the structure of the starch, and the presence of prot…

Under control: how a dietary additive can restore the gut microbiome and proteomic profile, and improve disease resilience in a marine teleostean fis…
2017
[Background]: The constant increase of aquaculture production and wealthy seafood consumption has forced the industry to explore alternative and more sustainable raw aquafeed materials, and plant ingredients have been used to replace marine feedstuffs in many farmed fish. The objective of the present study was to assess whether plant-based diets can induce changes in the intestinal mucus proteome, gut autochthonous microbiota and disease susceptibility of fish, and whether these changes could be reversed by the addition of sodium butyrate to the diets. Three different trials were performed using the teleostean gilthead sea bream (Sparus aurata) as model. In a first preliminary short-term tr…
