Non-alcoholic fatty liver disease (NAFLD) is considered a significant global health issue related to serious metabolic disorders. However, effective pharmacological treatments are still limited. Flavonoids, a wide group of polyphenol substances, exert anti-inflammatory and lipid-lowering effects in preclinical data. Thus, implementing these researc...

Anthocyanins are phenolic compounds occurring in fruits and vegetables. Evidence from pre-clinical studies indicates their role in glucose level regulation, gut microbiota improvement, and inflammation reduction under diabetic conditions. Therefore, incorporating these research advancements into clinical practice would significantly improve the pre...

Flavonols are one of the most plentiful flavonoid subclasses found in natural products and are extensively used as dietary supplements. Numerous in vitro and in vivo studies have shown the cardioprotective properties of flavonols, especially quercetin. This group of substances exerts positive impacts primarily due to their antiatherogenic, antithro...

Introduction and objective Shift work has a number of negative effects on human health. It often leads to sleep deprivation, changes of circadian rhythm, level of physical activity and eating habits, and also increases the risk of development of metabolic disorders and gastrointestinal diseases. The aim of the study was to indicate and discuss the...

Low-grade chronic inflammation (LGCI) and oxidative stress act as cooperative and synergistic partners in the pathogenesis of a wide variety of diseases. Polyphenols, including anthocyanins, are involved in regulating the inflammatory state and activating the endogenous antioxidant defenses. Anthocyanins’ effects on inflammatory markers are promisi...

Introduction Airway infections represent one of the most common causes of mortality worldwide. The authors sought to describe patients hospitalized for lung and mediastinum abscesses in Poland from 2009 to 2016. To the authors’ knowledge, this is the first evaluation of the disease in Poland. Material and methods The authors conducted a retrospect...

Age-related macular degeneration (AMD) is a progressively degenerative disease at the central area of the retina, which results in severe visual impairment. It is the leading cause of irreversible blindness among people aged over 65 in developed countries. Therapies that focus on prevention through optimization of modifiable risk factors such as di...

Age-related macular degeneration (AMD) is the leading cause of blindness in the world and may affect about 30-50 million people. Due to prevalence of this disease and the progressive population aging in recent years, in addition to conventional methods of treatment of AMD, there are more preventive and treatment support factors that can be used. An...

Birth weight is a key determinant of perinatal outcomes which affect physical development and metabolic function. In this study, we evaluated the potential role of maternal body composition and nutritional status in programing fetal birth weight. This was a longitudinal study that included 29 pregnant women and their full-term newborns. Maternal di...

Objectives: Pregnancy is a critical period during which environmental factors such as nutrition can affect development. Maintaining proper nutrition becomes even more significant when pregnant women have diabetes. The aim of this study was to measure changes in energy and macronutrient intakes among pregnant women and patients diagnosed either with...

Introduction. A social campaign promoting healthy lifestyle are a tool for establishing positive behavior patterns in a society, while mass media are an inseparable form of communication for promoting healthy lifestyle. Aim of the study. The aim of the study was to evaluate the effectiveness of selected social campaigns on proper nutrition, physica...

Introduction: Disorders of nutritional status have a significant impact on the dysfunction of many body systems. Emerging evidence suggests that abnormal nutritional status has a significant impact on the occurrence of bone degeneration, joint damage and it leads to an increased occurrence of back pain. According to WHO, 36% of boys and 23% of girl...

Overweight and obesity, a cluster of multiple risk factors for atherosclerosis such as elevated blood pressure, elevated glucose level, and dyslipidemia, increase the risk of all-cause mortality and cardiovascular morbidity and mortality. Physical activity and a proper diet are essential preventive measures. The aim of the study was to evaluate the...

In recent years, growing attention has been focused on the use of natural sources of antioxidants in the prevention of chronic diseases. Flavonoids are the examples of such substances. It is a group of bioactive compounds that are widely distributed in many plant-based foods and beverages. Flavonoid-rich products include, among others, berries, cit...

This study seeks to evaluate the metabolic parameters such as body mass index (BMI), percentage of total body fat percentage (%BF), blood glucose, homeostatic index for quantification of insulin resistance and beta-cell function (HOMA-IR), sleep efficiency, and physical activity in liver transplant patients. The study group consisted of 24 male and...

Background. Liver transplantation (LTx) is the ultimate treatment for some hepatologic patients (pts), very often observed having excessive weight gain after operation, resulting in an increased risk of non-communicable diseases (NCDs). Objectives. The aim of the pilot study was to evaluate the chosen lifestyle risk factors of NCDs (nutritional sta...

Noncommunicable diseases (NCDs), also known as chronic diseases, principally cardiovascular disease (CVDs), diabetes, neurodegenerative diseases, and cancer, continue to be a burden for health systems in both developed and developing countries. NCDs and their complications are responsible for an increased number of deaths and expensive medical cost...

Background: Flavonoids are a group of bioactive compounds that are extensively found in foodstuffs of plant origin. Their regular consumption plays an important role in the prevention of degenerative diseases, particularly cardiovascular disease, and cancer. Objective: The purpose of the study was to estimate dietary flavonoid intake among Polis...

Flavonoids are a group of bioactive compounds that are extensively found in foodstuffs of plant origin. Their regular consumption is associated with reduced risk of a number of chronic diseases, including cancer, cardiovascular disease (CVD) and neurodegenerative disorders. Flavonoids are classified into subgroups based on their chemical structure:...
