[The role of phytates in human nutrition].

Claims that consumption of phytate-rich grains, by definition, worsens mineral status needs to be clarified as new evidence emerges about the role of phytic acids (FA) from whole grains in improving population health outcomes. In this regard, it seems appropriate to draw the attention of practitioners to the need to correct patient's diet in order to prevent non-communicable diseases. The aim of this review was to generalize and analyze the modern data on the role of phytates in human nutrition. Material and methods. A search for domestic and foreign literature in the bibliographic databases of articles on medical sciences was carried out using the PubMed, MEDLINE and eLibrary search engines. Results. Deficit of minerals and trace elements in the diet, especially deficiency of iron, calcium, selenium, zinc, iodine, is an urgent public health problem in many countries. Calcium, magnesium, zinc, selenium, and iron deficiencies are associated with impaired immune function and an increased risk of both acute and chronic diseases. Vegan and vegetarian behavior styles with the restriction and exclusion of animal sources of bioavailable minerals and trace elements are gaining more and more popularity in our country. FA is the main storage form of phosphorus in nuts, grains, legumes, and seeds, which satisfies the biosynthesis needs of growing tissues during germination. FA is known as a dietary inhibitor that chelates minerals and trace elements, limiting their bioavailability and reducing their absorption. Pre-treatment methods to reduce phytate levels and increase the nutritional value of diets are fermentation, soaking, and sprouting. Reducing phytate content in plant foods by processing leads to a measurable improvement in mineral status, however, the chelating and antioxidant properties of phytates may be beneficial and their potential in the prevention of cancer, cardiovascular disease, diabetes mellitus and kidney stone formation is currently being studied. Conclusion. Essential components of a healthy diet are whole whole grains, legumes, vegetables, seeds and nuts, despite the fact that most of them are relatively high in FA. Despite some antinutrient properties, FAs have preventive effects on public health.

[Clinical efficacy of a modern probiotic for the correction of intestinal microflora in patients with irritable bowel syndrome with diarrhea and antibiotic-associated diarrhea].

Despite the fact that dietary supplements (DS) are not medicines, an increasing number of publications testify to the effectiveness of probiotics consumed with food in the complex treatment and prevention of a number of diseases of the gastrointestinal tract, including irritable bowel syndrome (IBS) and antibiotic-associated diarrhea (AAD). The purpose of the study was to evaluate the effectiveness of the complex probiotic in the relief of diarrheal syndrome associated with intestinal microbiota dysbiosis in patients with IBS with diarrhea and AAD. Material and methods. The study included 54 patients (31 with IBS with diarrhea and 23 with idiopathic AAD) aged 18 to 50 years. All patients included in the study were prescribed 1 capsule (350 mg) of the DS Neobiotic Lactobalance® per day for 21 days. One capsule contains: bifidobacteria (Bifidobacterium longum CBT BG7, Bifidobacterium lactis CBT BL3 Bifidobacterium bifidum CBT BF3), lactobacilli (Lactobacillus acidophilus CBT LA1, Lactobacillus rhamnosus CBT LR5), lactic acid bacteria (Streptococcus thermophilus CBT ST3), fructooligosaccharides, vitamin C. The daily intake of bifidobacteria was 8.7×108 CFU, lactobacilli - 6.1×109 CFU, lactic acid bacteria 3.1×108 CFU and vitamin C - 12 mg. The severity of symptoms was assessed in points (from 0 to 7 points) using the GSRS questionnaire (Gastrointestinal Symptom Rating Scale). All patients underwent a microbiological analysis of feces with an assessment of the degree of dysbiosis before and after the administration of DS. Results. In patients with IBS with diarrhea, the assessment of the manifestations of diarrheal syndrome according to the GSRS questionnaire decreased statistically significantly from 17 to 6 points (2.9 times), abdominal pain - from 12 to 4 points (3.0 times) and dyspeptic syndrome - from 8 to 3 points (in 2.7 times). In patients with AAD, also according to the GSRS questionnaire, the manifestations of diarrheal syndrome decreased statistically significantly from 13 to 3 points (4.3 times), abdominal pain - from 4 to 1 points (4.0 times) and dyspepsia syndrome - from 5 to 2 points (in 2.5 times). Against the background of DS intake, according to the data of bacteriological examination of feces, intestinal microbiota normalized by day 21 due to an increase in the number of lacto- and bifidobacteria (p=<0.05). Conclusion. The study showed that the DS Neobiotic Lactobalance® contributes to the normalization of the intestinal microbiota and reduces the severity of clinical manifestations (diarrheal disorders or manifestations of diarrhea) in IBS and idiopathic AAD.
