Background: This study assessed how two food groups—omnivores (OMN) and vegetarians (VEGE)—differ in lifestyle changes, including dietary habits during the COVID-19 pandemic. Materials: A total of 861 persons participated in the survey and were divided into two groups: persons following a mixed diet (n = 489) and vegetarians, including vegans (n = 372). The mean age shows no significant differences. Methods: 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). Results: 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 (p = 0.029), legumes (p < 0.001), and dairy products or their plant substitutes (p = 0.002), compared to the OMN group. Conclusions: The VEGE group revealed the most regularities in dietary habits during the pandemic.
本研究评估了两种食物群体——杂食者（OMN）和素食者（VEGE）在生活方式改变方面的差异，包括在 COVID-19 大流行期间的饮食习惯。
共有 861 人参与了这项调查，并分为两组：混合饮食组（n = 489）和素食者组，包括纯素食者（n = 372）。两组的平均年龄没有显著差异。
在 COVID-19 大流行期间，对波兰人口进行了在线调查。数据通过社交媒体收集；该调查针对成年人进行，包括针对不同饮食（OMN 与 VEGE）的单独问卷。
两组在导致过早发病的因素方面结果相似。大多数受访者（约 90%）没有报告心血管疾病异常。在 OMN 组中，超重和肥胖更为常见，而且 OMN 组报告体重增加的比例也更高（OMN 为 42.7%，VEGE 为 35.9%）。结果显示，VEGE 组选择蔬菜（p = 0.029）、豆类（p < 0.001）和奶制品或其植物替代品（p = 0.002）的频率显著高于 OMN 组。
VEGE 组在大流行期间的饮食习惯更有规律。
