Diet therapy is one of the main approaches to the treatment of a wide range of diseases of the digestive system. The treatment effectiveness of celiac disease depends on how strictly the patient adheres to a gluten-free diet. It is often disrupted due to the limited range of recommended foods and dishes, especially for children who are particularly sensitive to dietary restrictions. In this case, the development of new types of specialized gluten-free products is relevant, allowing to expand the diet both in terms of nutritional value and taste diversity. This study concerns the recipe developments of dry gluten-free mixtures using rice and amaranth with the inclusion of fruit and vegetable and berry raw materials intended for the nutrition of children over three years old suffering from celiac disease. When developing the recipes, researchers used various combinations of rice and amaranth flour, as well as fruit and vegetable powders. The rice flour composition varied in the range from 15 to 75%; amaranth – from 15 to 45%; fruit and vegetable and berry powders – up to 10%. The finished product was gluten-free cookies, muffins, pancakes made of rice and amaranth. Organoleptic evaluation showed that the studied samples of gluten-free cookies have high quality characteristics, have a pleasant taste and aroma. According to the calculated data, specialized gluten-free dry mixtures intended for children over three years with celiac disease can serve as an important source of: vegetable carbohydrates – from 26.81 to 55.19 g / 100g of finished products; protein – from 4.06 to 11.82 g/100g of finished products; dietary fiber – from 3.82 to 6.36 g/100g of finished products; and energy – from 158.12 to 333.96 kcal/100g of finished products) The developed recipess of gluten-free products can help to provide children with an adequate amount of nutrients and energy.

Gluten-free products based on starch and hydrocolloids are deficient in nutrients and do not contain pro-health substances. Therefore, they should be enriched in raw materials naturally rich in antioxidants, especially if they are intended for celiac patients, prone to high oxidative stress. Apart from the traditionally used pseudo-cereals, seeds, vegetables and fruits, innovative substrates such as the by-product (especially in Poland) dry apple pomace could be applied. The study material consisted of gluten-free bread enriched with apple pomace. The content of individual polyphenols, the content of total polyphenol and flavonoids, and also the antioxidant potential of the bread were determined by the UPLC-PDA-MS/MS methods. It was observed that apple pomace was a natural concentrate of bioactive substances from the group of polyphenols. In summary, gluten-free bread with 5% content of apple pomace showed the highest organoleptic scores and contained high levels of phenolic compounds. The values of total phenolic content, and the amounts of flavonoids, phenolic acids and phloridzin in this bread were 2.5, 8, 4 and 21 times higher in comparison to control.

Cookies, which form the largest category of bakery snacks, are considered a good vehicle to introduce nutrients into the diet. In this study, to increase the nutritional value of traditional commercial cookies, wheat flour was substituted with defatted flours made from flax, sesame, chia, and poppy, which are byproducts of the oil extraction industry. The differences in the technological properties, nutritional composition, and consumer acceptance of the reformulated cookies were evaluated. The results show that the wheat cookies used as the control showed a more elastic behavior than the cookies elaborated with defatted seed flours, which showed a greater tendency to crumble. The use of defatted seed flours yielded cookies with a higher content of protein and fiber, and a lower content in carbohydrates than the wheat cookies. Consumer evaluations for the sesame and flax cookies were similar to those for the traditional wheat cookies, with positive assessments on all of the parameters evaluated. On the other hand, the cookies elaborated using chia and poppy flours received the least positive evaluations from consumers. Thus, the use of some defatted seed flours, mainly flax and sesame, is proposed as an interesting alternative to produce health-promoting cookies in order to cover the current demand for gluten-free products.

The rise in gluten consumption over time has led to the increasing recognition of coeliac disease (CD) with associated complications. However, only recently has there been an appreciation that the spectrum of gluten-related disorders is greater than just CD, which may explain the growing global popularity in gluten-free products. Current literature suggests that a newly recognised clinical entity in the form of non-coeliac gluten sensitivity (NCGS) may be the most common gluten-related disorder encountered by healthcare professionals, although its exact prevalence is as yet unknown. This article will review the historical relationship between mankind and gluten as well as the progressive recognition that it is possible for gluten to have a deleterious effect on our health. To this effect we discuss the prevalence, diagnosis and complications of CD including the benefits derived from a gluten-free diet (GFD). Finally, we discuss our current understanding of NCGS, in addition to highlighting the need for further research to determine the extent, clinicopathological features and serological biomarkers to help recognise this emerging condition in clinical practice.

Introduction: Dietary trends such as consumption of lactose-free and gluten-free products or the use of alternative slimming diets are gaining increasing popularity, especially among young people. They determine their dietary choices, which are important from the point of view of human health. Unconventional diets are still considered as effective weight loss methods. The use of alternative diets may cause shortages of an essential nutrients, increase the risk of chronic non-communicable diseases and lead to the formation of incorrect eating habits. Balanced diet, in contrast to the alternative diet, takes into account the principles of rational nutrition and nutritional recommendations of the Institute of Food and Nutrition (IŻŻ). The aim: To investigate the influence of popular dietary trends on nutrition of high school adolescences. Material and methods: Subjects were adolescences in the age of 17-21 years attending high schools in Ruda Slaska (262 students, including 157 women and 105 men). Self-constructed questionnaire was applied in the study. Participation in the study was anonymous and voluntary. Results: In more than a half of young women (54,8%) and men (52,4%) the body mass deficiency was revealed (BMI<18 kg/m2). 33,6% of the respondents were on the non-balanced diets at least once in their lives. High school students knew gluten-free and lactose-free products but dietary trends, such as the consumption of gluten-free and lactose-free products, did not affect their diet. The main source of nutritional knowledge among respondents were their friends (78,2%). Conclusions: The results of the conducted research indicate the need to implement educational programs on the principles of proper nutrition. The increasing awareness of theyouth in this regard may contribute to reducing the interest in still popular alternative diets among young people and taking appropriate health behaviors by them.

The article highlights a complex of studies and a comparative assessment of flour of various varieties and hybrids of chia and sorghum. It was found that, in terms of their chemical composition, these crops are advisable to use as raw materials for the production of gluten free products. To live a full life, people with celiac disease must constantly consume gluten-free foods. Rice, buckwheat, millet, corn are considered safe, and amaranth, quinoa, sago, Setaria italica, sorghum are also less common in Ukraine. To obtain high-quality gluten-free products, it is important to choose the right raw materials and their ratio in chemical composition. Therefore, it is advisable to study and compare the chemical composition of sorghum and chia flour. The aim of the research was to study and compare the chemical composition of whole grain sorghum flour versus chia for use in the food industry as a source of gluten-free nutrition. The experimental part of the work was carried out during 2017–2019 in the hybrids of grain sorghum of Ukrainian (Lan 59), French (Targga) and American (Prime) selection and Spanish sage (chia) (Salvia hispanica) varieties: Salba, Tzotzol, Iztac. Whole grain sorghum and chia flours were obtained from their grains and various chemical constituents were determined. Comparative analysis of the chemical composition of sorghum and chia flour allows us to note that, on average, the protein content in sorghum was in the range from 9.53 to 10.6 g, in chia varieties from 14.98 to 16.52 g, which is on average five, 8 g more. The data on the determination of fats show that in the hybrid of sorghum of Ukrainian selection, this indicator was 2.8 g, French 1.24 g, and American – 3.3 g, as for chia, this indicator is much higher and varies by varieties from 30, 12 to 30.71 g. Starch is the main component of flour and in sorghum; its mass fraction is more in the Prime hybrid 63.7 g, Lan 59 – 63.1 g and the smallest amount in Targga – 62.7 g. It has been determined that grain sorghum and chia flour has a high content of B vitamins, which act as coenzymes of a number of metabolic processes. In addition to the vitamins listed above, sorghum flour contains vitamins B9, B5, B6 as well. Chia varieties have high levels of micro- and microelements. Key words: flour, vitamins, microelements, proteins, fats, carbohydrates, celiac disease, sorghum, chia.

Introduction. Diet therapy is one of the main approaches to the treatment of various diseases of the digestive system. A strict lifetime diet is the main method of treatment for gluten intolerance. However, young patients, who are particularly sensitive to dietary restrictions, often fail to follow the diet due to the limited menu of recommended foods and dishes. The diet for children with gluten intolerance should include a sufficient amount of gluten-free grain-based products. They provide children with carbohydrates, dietary fibers, vegetable proteins, fats, B vitamins, and minerals, e.g. potassium, magnesium, selenium, etc. In this regard, it is urgent to develop new types of specialized gluten-free products to expand the diet both in terms of nutritional value and taste diversity. Study objects and methods. The research is part of a project on the development of dry gluten-free mixes based on buckwheat and amaranth with fruit, vegetable, and berry raw materials. The new formulations are intended for children older than three years of age with gluten intolerance. The research objective was to study the main nutrients in amaranth and buckwheat flours. The study involved the method of infrared spectroscopy using a SpectraStar 2500 analyzer. The data obtained made it possible to calculate the nutritional and energy value of products based on amaranth and buckwheat flours, as well as fruit, vegetable, and berry powders intended for children older than three years of age with gluten intolerance. Results and discussion. Amaranth flour proved to be rich in protein (13.4%), lipids (5.1%), and ash (2.8%). Native buckwheat flour contained 7.5% of protein, 3.6% of lipids, and 1.4% of ash. The carbohydrate content appeared approximately the same in both samples (56–58%). The dry gluten-free mixes can serve as an important source of vegetable protein (up to 9.44 g per 100 g of the finished product), carbohydrates (up to 40.08 g per 100 g of the finished product, and energy (from 158.12 to 221.85 kcal per 100 g of the finished product). Conclusion. The high nutritional and biological value of amaranth and buckwheat flours, as well as fruit, vegetable, and berry powders, confirmed the prospect of using them as the main components for functional foods. Amaranth and buckwheat contain no gluten but are rich in protein, amino acids, saturated and unsaturated fatty acids, minerals, and biologically active elements, which makes them an important source of nutrition for children with gluten intolerance.

AbstractHealthy nutrition requires the intake of all macronutrients and micronutrients in optimal ratio and quantity. Nowadays, many people tend to gluten-free food without health and medical reasons. Many gluten-free products are nutritionally poorer than gluten-containing analogues. Although in many cases gluten-free products are nutritionally rich (either naturally or as a result of fortification), the bioavailability of nutrients is limited. The study focused on the influence of a six-week consumption of gluten-free bread and bakery products on mineral status in thirty healthy people without coeliac disease and the impacts eight weeks after the end of the consumption. Since the recommended daily intake for phosphorus, calcium, magnesium and iron was satisfied at only 84–88% for our volunteers, we consider the increase in the average serum levels of the monitored parameters to be positive (except for calcium). The six-week consumption of gluten-free bakery products had a positive effect on the mineral status of the monitored group of healthy consumers. We found a significant increase in phosphorus (P < 0.001) and magnesium (P < 0.01) levels, a certain increase in iron (P > 0.05), whereas the level of calcium insignificantly lowered (P > 0.05).
