Dietary Habits and Lifestyle, Including Cardiovascular Risk among Vegetarians and Omnivores during the COVID-19 Pandemic in the Polish Population.

This study assessed how two food groups-omnivores (OMN) and vegetarians (VEGE)-differ in lifestyle changes, including dietary habits during the COVID-19 pandemic. A total of 861 persons participated in the survey and were divided into two groups: persons following a mixed diet ( = 489) and vegetarians, including vegans ( = 372). The mean age shows no significant differences. An online survey was conducted on the Polish population during the COVID-19 pandemic. Data was collected using social media; the survey was intended for adults and included separate sheets for different diets (OMN vs. VEGE). The results in both groups were similar regarding the burden of premature diseases. Most respondents (~90%) did not indicate cardiovascular disease abnormalities. In the OMN group, overweight and obesity occurred more often, and the OMN group also showed a higher percentage of people reporting weight gain (OMN 42.7% vs. VEGE 35.9%). The results disclosed the VEGE group significantly more frequently chose products, i.e., vegetables ( = 0.029), legumes ( < 0.001), and dairy products or their plant substitutes ( = 0.002), compared to the OMN group. The VEGE group revealed the most regularities in dietary habits during the pandemic.
