Background. The links between dietary patterns, the perception of one’s body weight and diet as well preparing meals are poorly recognised in the literature. In order to develop effective nutritional education and focused interventions, more of such information is thereby required to improve the nation’s health. Objective. To identify dietary patterns based on declared food consumption rates and subject responses on whether dieting, perception of body weight and diet and preparing meals are linked to such dietary patterns. Material and methods. The survey was conducted in 2016 on 344 consumers chosen for age (20-65 years) and their consent for study participation. Rates of eating the foods selected were measured using a 7-point scale. Cluster analysis was used to identify three dietary patterns of behaviour: ‘potentially beneficial to health’, ‘potentially unfavourable for health; deficient’ and ‘potentially unfavourable for health; excessive’. The analysis was performed using IBM SPSS Statistics version 23.0. Results. There were significantly more subjects showing ‘potentially beneficial for health’ behaviour, normal body weight, those dieting (whether now or in the past) and those who evaluated their diet as being very good or good compared to other groups. They were also more involved in preparing their meals at home. Differences were found between the ‘unfavourable for health’ dietary patterns concerning subject’s involvement in meal preparation. The dietary pattern for ‘deficient’ behaviour found lower rates of those preparing their meals at home. Conclusions. The pattern of potentially beneficial dietary habits was linked to weight control through a slimming diet and greater involvement in the preparation of food for consumption. The results show the need to develop food choice skills rather than just transferring knowledge in the nutrition education process.
Food and nutrient goals for Polish population for the year 2000 formulated by the research workers from the National Food and Nutrition Institute and consulted with other nutrition specialists are presented. The concepts used in their preparation are described and the description of former Polish experiences in the formulation and implementations prospective food and nutrient patterns is included as well. The food goals for the year 2000 assume significant decrease of the consumption of visible fats and sugar. Taking into account the feasibility of the recommendations, very moderate increase in meat and milk consumption was suggested and more considerable one in case of fish. According to recommended food pattern the importance of fruit in the diet should grow very significantly. Implementation of the specified food goals will ensure the decrease of the energy content of the diet in relation to its current level and the reduction in the proportion of calories derived from fat.
Long-term changes in the national diet and in the CHD mortality rate in Poland were examined. The level and the composition of the national diet was assessed on the basis of the food balance sheets data. Statistics of the Central Statistical Office were used to study the trends in he CHD mortality rate. The period covering 1960—1989 was considered. It was shown that the CHD mortality rate rose fivefold between 1960 and 1989 while the total morality rate increased by some 40 per cent. It was revealed that Polish national diet was shifting towards more affluent one over this period. Alcohol consumption and tobacco use were subject to considerable increase too in the last three decades. It was demonstrated that there was a temporary decrease in the CHD mortality rate covering the period of 1979—1982. This decrease coincided with severe economic crisis which contributed to transitory reverse in the former long-term upward trend in the consumption of atherogenic foods, alcohol and tobacco.
The study was conducted on a group of 556 men. Their manner of nutrition was evaluated by the frequency of consumption of food items during last three months and also a 24 — hour consumption questionnaire was used. Dietary patterns were estimated by cluster analysis. According to the frequency of consumption, three dietary patterns were identified. In three conducted studies during 9 years, increased occurrence of the first dietary pattern, clasified as beneficial, was observed. On the contrary, the occurrence of the least beneficial pattern in nutritional sense was decreased. In each of those three studies, the level of education and physical activity, among others, affected the manner of nutrition.
Background. Dietary patterns (DPs) are defined as the amounts, types and combinations of various food products in habitual diets and the frequency of their consumption. Dietary pattern analysis is usually performed in order to assess the combined effect of consumed food products on health. Objective. The aim of the study was to assess and compare the nutritional value of dietary patterns identified in a group of patients staying on the oncological ward. Material and methods. The study group consisted of 100 patients (51 women and 49 men) aged 19-83 years. Dietary intake was assessed using a food frequency questionnaire (FFQ) validated for the population of Lower Silesian Voivodeship. Results. Factor analysis identified two main dietary patterns explaining 25.6% of variance. The “fruit and vegetables” DP consisted of vegetables, fruits, juices, unrefined grains and nuts, seeds and raisins. Instead, the “Western” DP was characterized by the consumption of high-fat and processed meat and poultry, fried fish, refined grains, honey and sugar, fats, sweets, beverages and chips. While higher scores for “fruit and vegetables” pattern were associated with increased intake of dietary fiber, antioxidant vitamins, folic acid and decreased glycemic load per 1000 kcal and sodium intake, for “Western” pattern observed relationships were opposite. Women were more likely to have higher factor scores for “fruit and vegetables” DP and lower factor scores for “Western” DP than men. Conclusions. Dietary patterns identified in the study group differed in terms of nutritional value, in spite of similar macronutrient content in the diet. “Western” DP was characterized by lower nutritional value than “fruit and vegetables” dietary pattern.
