The differences between the metabolism and the physiology of cancer cells and the cells of the human body are assessed and used in most anticancer treatments. These differences encompass, among others, increased glucose metabolism in the changed cells. The aim of the paper was to discuss the results of studies concerning the relationship between lowcarbohydrate diets and fasting and the course of cancer. An inappropriately composed diet consisting of high amounts of simple sugars supplies cancer cells with nutrients, which may impair the effectiveness of cancer patients treatment. Lowcarbohydrate diets may, therefore, constitute an element of supplementary therapy in cancer treatment. The mechanism of low-carbohydrate diets in combination with standard treatment has not been completely explained, though. In initial studies it was proven that patients who were able to continue low-carbohydrate diets showed improvement in health and reduction of tumor mass or its slower growth. Moreover, it was observed that the inability of cancer cells to adapt in new environmental conditions that occur while fasting may have toxic effect on them. Introduction of fasting may sensitize cancer cells to chemotherapy, decrease concentration of growth factors and lead to repair of normal cells. On the other hand, fasting may also promote autophagy and, as can be concluded from the literature, its mechanism may have twofold activity: as a process impacting the survival or death of cancer cells.
Background: Proper nutritional behaviors are one of the most important factors shaping our health, as they influence people's physical and mental state. Good eating habits help prevent many chronic diseases, including cardiovascular disease, type II diabetes, some types of cancer, and osteoporosis. The Polish population aged 20-34 years displays improper nutritional behaviors which may put them at risk of developing diet-dependent diseases in the future. There is a need to assess students' lifestyle, including their eating habits, as it would help adapt already existing education programs. Objective. We evaluated and compared eating habits and lifestyle of students studying cosmetology and physiotherapy in association with selected risk factors of civilization diseases. Material and methods. We used a standardized dietary questionnaire evaluating respondents' physical activity, smoking and dietary habits. The obtained results were compared with the recommendations from the Polish food-based dietary guidelines. We evaluated respondents' nutritional status based on their anthropometric measurements such as body weight, body height, hips and waist circumferences and then we estimated their body mass index (BMI) and waist hip ratio (WHR). Results. Students studying cosmetology and physiotherapy obtained on average 5.3 ±1.5 points based on their compliance with the nutritional recommendations. The academic youth did not meet principles of healthy nutrition according to the given recommendations. There were no significant differences in nutrition status between the faculties, except for products that provide complete protein. Conclusions. There is a need to increase nutritional awareness of academic youth, especially students of health-related faculties, because better knowledge on nutrition would help them choose healthier food options.
Background. Nutrition education is one of the most important factors determining the effectiveness of treatment and maintaining an adequate quality of life (QoL) in children and adolescents with type 1 diabetes. Objective. The primary objective was to compare the influence of two methods of nutrition education on the QoL. The secondary objective was to identify other determinants of the QoL. Material and Methods. A randomized single-blind study was conducted between October 2017 and April 2019 at the Children’s Clinical Hospital in Warsaw. The study included 170 patients (aged 8-17) with at least 1-year history of type 1 diabetes, treated with insulin pumps. The participants were randomly divided into two groups: a control group (C) – traditional/ informative education methods, and an experimental group (E) – modern/interactive methods. PedsQL Diabetes Module 3.0 questionnaire was used in the assessment of the QoL. Total PedsQL score was the primary outcome. The secondary outcomes included the results obtained in five subscales of the questionnaire. The relationships between selected variables and changes in scores were also verified. Results. Data obtained from 136 patients were analyzed. In both groups no significant changes regarding total PedsQL were noted 6 months after the intervention. However, a significant reduction occurred as regards the scores of ‘Communication’ subscale in group C. Analyzing other determinants of the QoL, significant dependencies were observed between: the level of physical activity and a change in ‘Diabetes symptoms’ subscale, and the level of parents’ education and a change in ‘Treatment barriers’ subscale. Conclusions. Both methods of nutrition education exerted a comparable influence on the total QoL. However, modern methods were more effective in terms of the improvement in the aspect of communication. Additionally, moderate physical activity and parents’ tertiary education constituted valid determinants of various aspects of the QoL in children and adolescents with type 1 diabetes.
