Vegetarian Diet in Children: Benefits, Drawbacks and Risks

Introduction Vegetarianism is an eating pattern centred on plant-based food. It encompasses many diets that differ in terms of whether they contain goods originating from animals, like milk and eggs. Nowadays, vegetarianism is increasing in popularity in developed nations, particularly in Europe. Individuals choose vegetarian diets for reasons related to health, ethics, or ecology. The rising popularity of vegetarian diets is not limited to adults but is also increasing among children. Aim of the study Vegetarian diets are generally considered to be beneficial for health. However, there are concerns over the ability to meet the dietary requirements necessary during infancy, youth, and adolescence on a vegetarian diet. Therefore, the primary aim of this systematic review is to answer questions about the efficacy of a plant-based diet in meeting the nutritional requirements of children and how to avoid the risk of nutritional deficiencies among vegetarian children. Material and methods Article provides an overview of the current literature about the vegetarian diet in children. The information has been collected from a comprehensive search of electronic databases, scientific journals, and statement papers published by nutrition and paediatric organisations. Results Following a vegetarian diet can be a beneficial decision for all children, assuming that it is properly organised and well balanced. The majority of paediatric and nutrition organisations do not recommend more strict diets for children, such as a vegan diet, which fully excludes not only meat but all animal products

Advantages of oral collagen supplementation. Review of the literature

IntroductionCollagen is a protein that has found widespread use both as an ingredient in cosmetics applied externally and as an oral supplement. This substance is obtained from a number of animal sources, including bovine tissues, as well as marine fish. The characteristic properties of collagen peptides, such as scientifically proven anti-inflammatory effects, activation of fibroblast skin cells, stimulation of synovial cells to produce hyaluronic acid, and much more make this type of supplement promising in improving the body's general condition and in alleviating the symptoms of many ailments. Numerous scientific studies have shown that supplementation with hydrolyzed collagen has a beneficial effect on both the overall condition of the skin by improving its elasticity, hydration level, and positive action on its protective barrier and on the musculoskeletal system, where, when combined with appropriately selected physical activity, it can help to reduce pain associated with conditions such as osteoarthritis and even increase the range of movement in the joints. Easy availability, user-friendly forms of administration, such as powders or ready-to-drink liquid formulations, and a low incidence of side effects make this supplementation highly beneficial for users.  Aim of the studyThis study aims to discuss the known processes and review the evidence supporting the beneficial effects of hydrolyzed collagen supplementation on the human skin and musculoskeletal system.Material and methodThis article presents the current state of knowledge about the benefits of oral collagen peptide supplementation in various scientific articles. Publications describing the mechanisms of action and the effects of collagen supplementation on skin conditions and the musculoskeletal system, including recent reports in this field, were reviewed using the PubMed platform. The search included the keywords ‘collagen’, ‘collagen supplementation’, ‘nutritional supplement’, ‘recovery
