Description Fruits and vegetables (F&V) are important components of a healthy diet. WHO and European Guidelines on cardiovascular disease prevention in clinical practice recommend daily intake at least 400 g of F&V (EU standard). According to current Dietary guidelines for the Czech Republic (Society for Nutrition, 2012) daily intake of F&V (including vegetables cooked) should reach 600 g (CZ Standard). The aim of our study was to estimate whether the population of the city of Brno reaches the recommended daily intake of F & V and whether there are differences between genders and groups according to age and BMI. Methods: A cross-sectional study "Kardiovize Brno 2030" was conducted in 2013 – 2014. A representative sample of the population of Brno aged 25-64 was examined, n=2160 (1183 women, 977 men). Data from food frequency questionnaire were used to evaluate the consumption of F & V (answers to questions: "How often have you consumed raw fruit / fresh vegetables / cooked vegetables during the past 7 days?"; "What affects your daily intake of F&V?"). The sample size allows an approximation that each individual consumption corresponds to one standard portion. Assuming that a standard serving size is about 100 g, recommended intake is achieved by 4 or 6 consumptions per day (EU standard or CZ standard respectively). Total daily consumption (total consumption of fruits, raw vegetables, cooked vegetables), numbers and probabilities of the occurrence of the recommended intake (CZ standard = 6 or more servings / day, EU standard = 4 or more servings / day) by sex, age and BMI groups were calculated. Zero value of the logarithm of relative risk was tested by Wald statistical test at a significance level of alpha = 0.05. Results: CZ standard met 3.5 % of women and 0.9 % men. EU standard met 16.2 % of women and 7.1 % men. Numbers of men with insufficient consumption are significantly higher in comparison with women. For both genders, all age groups and BMI categories the percentage of people with insufficient consumption was significantly higher compared to those who met the recommendations. Differences in achieving standards when comparing age groups and BMI categories were not statistically significant. Although fruit and vegetable intake was inadequate in our sample, 52% of the examined subjects assessed their consumption as sufficient.
