ABSTRACT
The aim of the study was to assess the lifestyle of a selected group of inhabitants of the Mazowieckie Voivodeship before the pandemic and to analyse the impact of lockdown on changes in lifestyle, including changes in the consumption of selected food products that are a source of vitamins and minerals. In August 2020, a survey was conducted based on a proprietary questionnaire. It was shown that during the lockdown period, 24.7% of women and 27.1% of men made changes in their lives. The changes concerned working hours, nature of work, hours of sleep, number of meals consumed and diet. The analysis of the diet showed a decrease in the consumption of vegetables, fruits and legumes in some respondents, which, with low frequency of consumption, may lead to a deficiency of dietary fibre, vitamin C, folic acid, polyphenols and potassium. The consumption of fish, spreadable fats, salt, sugar and drinks was not compliant with the recommendations of healthy eating. Public education about healthy lifestyles is essential to prevent complications from COVID-19.
