Even if the progression of this trend is difficult to measure at the European and global level, the popularization, the values of the younger generations and the awareness of the state of the environment, suggest the progression of vegetarianism.
Diet and eating habits change over time and are influenced by many social and economic factors. Nowadays, we can notice an awareness of the benefits of a healthy diet on people’s health. According to the WHO, a healthy diet is a diversified and balanced diet adapted to age, gender, lifestyle and physical exercise (14).
In Switzerland, a survey conducted in 2009 showed that “taste, quality and health, followed by diversity, balance and freshness” are priority factors for the population in terms of nutrition (15). According to a more recent survey, conducted by menuCH between 2014 and 2015, three out of four people have heard of the Swiss food pyramid and two thirds of people were aware of the “five a day” campaign (16).
Various entities and organizations also advocate for a healthy diet with a low environmental impact (17), the so-called planetary diet, i.e. a diet that is optimal from a health and ecological point of view (18).
