The main aim of this study was to identify the dairy sources of energy and 44 nutrients in the average Polish diet. Our research included: carbohydrates, protein, total fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), cholesterol, 18 amino acids, 9 minerals, and 10 vitamins. The analysis was conducted based on the data from the 2016 Household Budget Survey, a representative sample of the Polish population (i.e., 36,886 households). The category of milk and dairy products was divided into three main groups (i.e., milk, cheeses, and yoghurts, milk drinks and other dairy products) and seven sub-groups (i.e., whole milk, reduced fat milk, condensed and powdered milk, ripened and melted cheese, cottage cheese, yoghurts, milk drinks and other dairy products). Milk and dairy products provided 9.1% of the total energy supply. A high share (above 20%) in the supply of nutrients was noted in the case of calcium (54.7%), riboflavin (28.1%), vitamin B12 (26.1%), and phosphorus (24.6%). Supply at the level of 10–20% was observed for protein, SFA, zinc, total fat, cholesterol, potassium, magnesium, and vitamin A. Of the amino acids, the share above 20% from dairy category was recorded in the case of 6 amino acids (proline, tyrosine, serine, lysine, valine, and leucine) and at the level of 10–20% for 10 amino acids (isoleucine, histidine, threonine, tryptophan, phenylalanine, methionine, glutamic acid, aspartic acid, alanine, and arginine).

The main aim of this study was to identify the food sources of energy and 28 nutrients from cereals and cereal products in the average Polish diet based on data from a nationally representative sample of the Polish population attending in 2016 Household Budget Survey (i.e., 36,886 households). The contribution of energy and nutrients from cereals and cereal products were compared with reference values. The detailded analysis included five main groups and nine sub-groups of cereal food category. Our findings indicated that cereals and cereal products contributed 30.4% of total dietary energy supply, providing a significant percentage of six nutrients to the average Polish diet (i.e., 64.1% of manganese, 51% of carbohydrates, 48.5% of dietary fibre, 34.1% of iron, 33.6% of folate, and 31.3% of copper). Supply at the level of 20–30% was observed for protein, thiamin, phosphorus and zinc, and at 10–20% for polyunsaturated fatty acids (PUFA), sodium, potassium, calcium, riboflavin, niacin, and vitamin B6. For other nutrients i.e., total fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), cholesterol, iodine, vitamins: A, D, B12, and C, the share of cereals and cereal products contribution was below 10%. Cereals and cereal products were the major food category in meeting the reference values for the Polish population in case of manganese, carbohydrates (approximately 100%), and sodium (50%). The reference values was reached at the level of 30–40% for dietary fibre, protein, iron, copper, zinc, phosphorus and thiamin, and 20–30% for energy, magnesium, folate, niacin, riboflavin, vitamins B6 and E. For such nutrients as total fat, SFA, and potassium, the fulfillment of the reference values amounted to 10–20%. Our results document the importance of cereals and cereal products in the Polish diet, which should be emphasized from a nutritional and health point of view.

The aim of this study was to identify the food sources of protein and 18 amino acids (AAs) in the average Polish diet. The analysis was conducted based on the 2016 Household Budget Survey (HBS) on the consumption of food products from a representative sample of 38,886 households (n = 99,230). This survey was organized, conducted and controlled by the Central Statistical Office, Social Surveys and Living Conditions Statistics Department in cooperation with the Statistic Office in Łódź based on the recording of expenditures, quantitative consumption, and revenues in budget books for one month. 91 food products from 13 food categories (e.g., meat and meat products, grain products) consisting of 42 food groups (e.g., red meat, milk, cheese) were analyzed to determine protein and amino acid intake from these products. Three categories delivered 80.9% of total protein (meat and meat products: 38.9%; grain products: 23.9%; and milk and dairy products: 18.1%). The branched-chain amino acids (BCAAs: leucine, isoleucine and valine) were delivered mainly by meat and meat products (39.9%; 41.3% and 37.4%, respectively). Meat and meat products were also the most important source for other essential amino acids (EAAs: lysine 49.2%, histidine 46.6%, threonine 44.7%, tryptophan 41.4%, phenylalanine 35.3%, and methionine 44.2%). In terms of the contribution of the non-essential or conditionally essential amino acids to the average Polish diet, most important were grain products (for cysteine: 41.2%; glutamic acid: 33.8%; proline: 34.1%), and meat and meat products (for tyrosine: 38.3%; arginine: 46.1%; alanine: 48.7%; aspartic acid: 41.7%; glycine: 52.5%; serine: 33.6%). Five clusters were identified to assess the impact of socio-demographic and economic factors on the protein supply. The largest impact was observed for respondent education, degree of urbanization, study month, and usage of agricultural land. The shares of animal food in total protein supply amounted to 66.5% in total population and varied from 56.4% to 73.6% in different clusters.

This study aimed to examine the drivers and types of sustainable product innovations undertaken in bakeries with a particular focus on fibre-enriched bread. This type of bread contributes to a healthy diet due to its increased content of dietary fibre, which is an essential but deficient component of the diet, especially in modern consumption patterns in affluent countries. The study was carried out using the Computer Assisted Telephone Interview (CATI) method on a sample of 402 companies operating in the Polish baking industry. Multiple correspondence analysis (MCA) using Burt tables was used to analyse the results. Four groups of companies were identified according to the number of new products introduced to the market: non-innovative, poorly innovative, moderately innovative, and sustainable innovative companies. The results show that the development of a “new formula” was the most frequently mentioned type of innovation in all groups of companies. Other types of product innovation were also identified among the highly innovative companies: a new product for the company, a new product for the consumer, and new packaging. The basic motivation for launching innovative products on the market was to follow new trends and meet consumer expectations. Therefore, the results indicate that a consumer approach to innovation prevailed. The surveyed bakeries perceived fibre-enriched bread as a product with high nutritional value and environmental benefits. Our results contribute to a better understanding of the drivers of sustainable innovation in the food industry and have some practical implications for bakery companies seeking competitive drivers based on sustainable innovation. The study showed that capturing the voice of the customer is important in developing product innovations in bakeries. A consumer-oriented strategy is a win-win strategy, as it will result in an increased range of products suitable for a healthy sustainable diet and environmental benefits using fibre waste from food processing.

Our study aimed to explore the factors limiting the development of the organic food sector in Poland from the perspective of processing, distributing, and retailing companies. We used a qualitative approach with in-depth semi-structured interviews with the management board representatives of 17 large- and medium-sized enterprises and the owners of 10 small and medium companies. The potential limiting factors, including legal, economic, technological, and environmental factors, were identified by reviewing the corporate and market reports of processing and retailing companies operating in the Polish organic sector. We used a thematic analysis recommended in the literature to analyze qualitative data. The main factors indicated by the managers were the legal concerns, limitations resulting from a lack of constant supply of organic raw materials, and increased competition on domestic and international markets. In addition, business activities in the Polish organic sector were affected by the instability of the financial situation in terms of financial liquidity, adequate cost, capital structure, and credits. The results of the study may be of value for policymakers to ensure sustainable development of the organic food sector in Poland.

This study aimed to analyze the international literature on consumer behavior toward private label (PL) products, guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) method. We searched for peer-reviewed studies published until January 2021 in the Scopus and Web of Science databases using two main search terms, namely, “consumer behavior” and “private label,” which have several synonymous terms, such as “store brand,” “private brand,” and “own label.” A total of 44 eligible studies were selected for the analysis. We formulated research questions regarding the most studied categories of PL products, the non-health factors determining consumer behavior toward PL products, and the frequency of including health aspects in the choice of PL products. The following were analyzed in the studies included in the systematic literature review (SLR): general data and study design (authorship, year of publication, location, characteristics of the sample, and research category), research specifications (factors/variables, hypotheses, and measured parameters), and general findings (findings and practical recommendations). We found that most of the studies had analyzed dairy products as PL products, and the main non-health selection factors used were lower price and price–quality ratios. Health aspects were considered in only four of the analyzed studies, which focused on the evolution of PL products from low-cost products to sustainable brands with significant added value in terms of quality and health aspects.
