Impact of Christian Orthodox Church Fasting on Metabolic Syndrome Components in Adults Aged 18-49 Years. Nutrients 2023; 15:nu15071755. [PMID: 37049597 PMCID: PMC10096952 DOI: 10.3390/nu15071755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 03/30/2023] [Accepted: 04/01/2023] [Indexed: 04/14/2023] Open
Abstract
OBJECTIVE Studies regarding health effects of religious fasting have been increased during the last decade. Our aim was to investigate the effects of Christian Orthodox Church (COC) fasting on metabolic syndrome in young adults. METHODS Participants were 224 men and women, of whom 111 had been following the COC fasting regime and 113 were non-fasters, all aged 18 to 49 years (mean age 29.23 ± 8.78 years). Anthropometric measurements, including the Bioelectrical Impedance Analysis, were performed on individuals, and they also completed food intake questionnaires, and provided blood samples for biochemical analysis. Metabolic syndrome was defined according to criteria of the National Cholesterol Education Program-Adult Treatment Panel III and all variables were checked. RESULTS Fasters did not statistically differ in anthropometric measurements when comparing to non-fasters. Differences were found in terms of biochemical variables, and more specific in HDL cholesterol, LDL cholesterol and total blood cholesterol, and in systemic and diastolic blood pressure, although non statistically significant. Statistically significant differences were only noticed in heart pulses and insulin levels, with fasters having lower heart pulses (69.44 ± 9.84 versus 72.63 ± 10.74) and greater mean values of insulin levels (4.16 ± 4.66 versus 3.12 ± 2.35). When analysis was carried to identify which variables were met for metabolic syndrome, it was found that fasters had statistically significant lower values of blood pressure when compared to non-fasters. In more details mean systolic blood pressure was 121.67 ± 12.21 versus 123.41 ± 11.73 for fasters and non-fasters respectively, and mean diastolic blood pressure was 75.77 ± 8.82 versus 78.27 ± 10.07 for fasters and non-fasters. Furthermore, the mean energy intake was higher in non-fasters (1698.25 ± 515.99 kcals) when compared to fasters (1590.24 ± 404.19 kcals) but not statistically significant different. CONCLUSIONS Young adults aged 18 to 49 years who fast according to the COC fasting regimes do not have different metabolic syndrome prevalence when comparing to non-fasters, but there was a statistically significant difference in the prevalence of elevated blood pressure with fasters having lower values.

Christian Orthodox Fasting as a Traditional Diet with Low Content of Refined Carbohydrates That Promotes Human Health: A Review of the Current Clinical Evidence. Nutrients 2023; 15:nu15051225. [PMID: 36904225 PMCID: PMC10004762 DOI: 10.3390/nu15051225] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Accepted: 02/27/2023] [Indexed: 03/05/2023] Open
Abstract
INTRODUCTION Christian Orthodox fasting is a pattern high in complex carbohydrates and low in refined carbohydrates. It has been explored in association with its potential health benefits. The present review aims to comprehensively explore the existing available clinical data concerning the potential favorable impact of the dietary pattern of Christian Orthodox fasting on human health. METHODS PubMed database, Web of Science and Google Scholar were extensively searched in order to identify the more appropriate clinical studies that explore the effect of Christian Orthodox fasting on health-related outcomes in humans utilizing relative keywords. We initially retrieved 121 records through database searching. After applying several exclusion criteria, 17 clinical studies were finally included in this review study. DISCUSSION Christian Orthodox fasting showed beneficial effects concerning glucose and lipid control, whereas the data for blood pressure remain inconclusive. Concerning weight control, fasters were characterized by lower body mass and lower caloric intake in the course of the fasting periods. During fasting, this pattern is higher in fruits and vegetables, showing the absence of dietary deficiencies for iron and folate. Nevertheless, dietary deficiencies were recorded for calcium and vitamin B2, and also hypovitaminosis D has been noticed in monks. Interestingly, the vast majority of monks do present with both good quality of life and mental health. CONCLUSIONS Overall, Christian Orthodox fasting is a dietary pattern low in refined carbohydrates and high in complex carbohydrates and fiber that may be beneficial for human health promotion and chronic disease prevention. However, further studies are strongly recommended on the impact of long-term religious fasting on HDL cholesterol levels and blood pressure.

Vitamin D and Calcium in Osteoporosis, and the Role of Bone Turnover Markers: A Narrative Review of Recent Data from RCTs. Diseases 2023; 11:diseases11010029. [PMID: 36810543 PMCID: PMC9944083 DOI: 10.3390/diseases11010029] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/01/2023] [Accepted: 02/03/2023] [Indexed: 02/11/2023] Open
Abstract
Osteoporosis is a common disease, defined primarily by a low measured bone density, which is associated with an increased risk of fragility fractures. Low calcium intake and vitamin D deficiency seem to be positively correlated with the prevalence of osteoporosis. Although they are not suitable for the diagnosis of osteoporosis, the biochemical markers of bone turnover can be measured in serum and/or urine, enabling the assessment of the dynamic bone activity and the short-term effectiveness of the osteoporosis treatment. Calcium and vitamin D are essential for maintaining bone health. The aim of this narrative review is to summarize the effects of vitamin D and calcium supplementation separately and in combination, on bone density and circulating serum and blood plasma vitamin D, calcium, parathyroid hormone levels, markers of bone metabolism concentrations, and clinical outcomes, such as falls and osteoporotic fractures. We searched the PubMed online database to find clinical trials from the last five years (2016-April 2022). A total of 26 randomized clinical trials (RCTs) were included in this review. The present reviewed evidence suggests that vitamin D alone or in combination with calcium increases circulating 25(OH)D. Calcium with concomitant vitamin D supplementation, but not vitamin D alone, leads to an increase in BMD. In addition, most studies did not detect significant changes in circulating levels of plasma bone metabolism markers, nor in the incidence of falls. Instead, there was a decrease in blood serum PTH levels in the groups receiving vitamin D and/or Ca supplementation. The plasma vitamin D levels at the beginning of the intervention, and the dosing regimen followed, may play a role in the observed parameters. However, further study is needed to determine an appropriate dosing regimen for the treatment of osteoporosis and the role of bone metabolism markers.

Abstract
Objective The aim of the study was to identify and describe the dietary patterns seen in a carefully selected sample that follows the Christian Orthodox Church (COC) fasting regime in Greece. Methods A number of 361 individuals from Northern Greece participated in this cross-sectional study. A number of 176 subjects have been fasting according to the COC recommendations since childhood and 185 non-fasters acted as the control group. Dietary data from a validated food frequency questionnaire were used to derive dietary patterns by principal component analysis (PCA). Results Three distinct dietary patterns were identified in the fasting population, the “COC Fasting,” the “Western,” and the “Traditional” dietary pattern, whereas in the non-fasting population, two dietary patterns were found the “Western” and the “Traditional.” The dietary patterns in the fasting population were associated with healthier lifestyle choices, such as abstaining from alcohol and smoke and reduced red and processed meats consumption. Conclusion Findings from the study revealed that people who adhere to the COC fasting recommendations since childhood tend to follow this dietary pattern throughout the year. By gaining insights into the energy and nutrient intake of this unique dietary pattern, public health stakeholders could promote healthier eating behaviors to prevent non-communicable chronic diseases, such as obesity and metabolic syndrome.

Abstract
Aging in modern societies is often associated with various diseases including metabolic and neurodegenerative disorders. In recent years, researchers have shown that both dysfunctions are related to each other. Although the relationship is not fully understood, recent evidence indicate that metabolic control plays a determinant role in neural defects onset. Indeed, energy balance dysregulation affects neuroenergetics by altering energy supply and thus neuronal activity. Consistently, different diets to help control body weight, blood glucose or insulin sensitivity are also effective in improving neurodegenerative disorders, dampening symptoms, or decreasing the risk of disease onset. Moreover, adapted nutritional recommendations improve learning, memory, and mood in healthy subjects as well. Interestingly, adjusted carbohydrate content of meals is the most efficient for both brain function and metabolic regulation improvement. Notably, documented neurological disorders impacted by specific diets suggest that the processes involved are inflammation, mitochondrial function and redox balance as well as ATP production. Interestingly, processes involving inflammation, mitochondrial function and redox balance as well as ATP production are also described in brain regulation of energy homeostasis. Therefore, it is likely that changes in brain function induced by diets can affect brain control of energy homeostasis and other brain functions such as memory, anxiety, social behavior, or motor skills. Moreover, a defect in energy supply could participate to the development of neurodegenerative disorders. Among the possible processes involved, the role of ketone bodies metabolism, neurogenesis and synaptic plasticity, oxidative stress and inflammation or epigenetic regulations as well as gut-brain axis and SCFA have been proposed in the literature. Therefore, the goal of this review is to provide hints about how nutritional studies could help to better understand the tight relationship between metabolic balance, brain activity and aging. Altogether, diets that help maintaining a metabolic balance could be key to both maintain energy homeostasis and prevent neurological disorders, thus contributing to promote healthy aging.

Effects of Periodic Religious Fasting for Decades on Nutrient Intakes and the Blood Biochemical Profile. Nutrients 2021; 13:nu13113963. [PMID: 34836217 PMCID: PMC8619925 DOI: 10.3390/nu13113963] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 11/04/2021] [Accepted: 11/04/2021] [Indexed: 11/16/2022] Open
Abstract
The aim of the present study was to examine differences and correlations in nutrient intakes and serum parameters related to nutrient intake (lipid profile, vitamins, and trace elements) in 200 lifelong Christian Orthodox Church (COC) fasters with periodic abstinence from certain foods (predominantly of animal origin) for approximately half of the year and 200 non-fasting controls, all of whom did not take dietary supplements. Nutrient intakes were assessed through three-day dietary recalls. Blood samples were drawn for the analysis of potential biomarkers of nutrient intake. Fasters had lower energy intake, due to lower fat and protein intake, compared to non-fasters (p < 0.05). Fasters also had lower intakes of vitamins A, B1, B2, B6, B12, D, folate, pantothenate, sodium, calcium, zinc, and phosphorus. Most participants (in both groups) did not meet the recommended dietary allowances of most vitamins and elements. Most serum biochemical parameters did not reflect the differences in nutrient intakes between groups, and none exhibited a correlation coefficient above 0.5 with nutrient intakes. Our findings suggest that COC fasting is associated with reduced intake of many nutrients, although this does not seem to have an impact on the blood biochemical profile.

Abstract
Fasting has been a practice among followers of different religions for many years. Christian Orthodox Church (COC) fasting is a periodic vegetarian-type diet while seafood and snails are allowed on most fasting days. The present scoping review aimed to present available data regarding the benefits of COC fasting on metabolic syndrome (MetS) risk factors. Databases were searched for available studies. Twenty publications, with a total of 1226 fasting participants, provided data on the effects on different variables of the MetS, including blood pressure, blood lipids and anthropometric measurements. Fasters' diet is characterized by low saturated and trans fat intake, high complex carbohydrate and fiber consumption, due to foods allowed to consume. COC fasting has no deficiency in essential amino acids intake since seafood and snails allowed on fasting days. Fasters have healthier blood lipid profiles during and after COC fasting periods, total cholesterol, low-density lipoprotein cholesterol, systolic blood pressure, body weight and body mass index are reduced after a fasting period. Due to restricted or forbidden intake of specific foods during the COC fasting periods, one might expect that fasters may have reduced intake of macro- and micro-nutrients, but as showed in the available literature there are no deficiencies. Future research on COC fasting is needed in areas not investigated at all, like MetS, before reaching definite conclusions.

Abstract
We investigated whether periodic abstinence from foods of animal origin and a conservative lifestyle, with reduced sunlight exposure, affect vitamin D status. In a cross-sectional design, we measured the serum 25-hydroxyvitamin D concentration and assessed dietary vitamin D intake and sunlight exposure in 200 adults adhering to religious fasting for decades and in 200 non-fasters, with no differences between groups in bone mineral density. Fasters showed lower 25-hydroxyvitamin D concentration than non-fasters in winter and spring. Vitamin D intake and some indices of sunlight exposure (including two related to winter and spring) were lower in fasters, and 378 of the 400 participants exhibited vitamin D insufficiency or deficiency. In conclusion, individuals following a religious lifestyle had lower vitamin D intake, sunlight exposure and, at times, serum 25-hydroxyvitamin D concentration than controls, although these differences did not impact bone health.

Abstract
Lifestyle choices significantly influence mental health in later life. In this study we investigated the effects of the Christian Orthodox Church (COC) fasting diet, which includes long-term regular abstinence from animal-based products for half the calendar year, on cognitive function and emotional wellbeing of healthy adults. Two groups of fasting and non-fasting individuals were evaluated regarding their cognitive performance and the presence of anxiety and depression using the Mini Mental Examination Scale, the Hamilton Anxiety Scale, and the Geriatric Depression Scale (GDS), respectively. Data on physical activity, smoking, and vitamin levels were collected and correlated with mental health scoring. Negative binomial regression was performed to examine differences in the GDS scores between the two groups. Significantly lower levels of anxiety (7.48 ± 4.98 vs. 9.71 ± 5.25; p < 0.001) and depression (2.24 ± 1.77 vs. 3.5 ± 2.52; p < 0.001), along with better cognitive function (29.15 ± 0.79 vs. 28.64 ± 1.27; p < 0.001), were noticed in fasting compared to non-fasting individuals. GDS score was 31% lower (Incidence Rate Ratio: 0.69, 95% Confidence Interval: 0.56–0.85) in the fasting group compared to the control, while vitamin and ferrum levels did not differ. The COC fasting diet was found to have an independent positive impact on cognition and mood in middle-aged and elderly individuals.

Abstract
We examined whether bone health is related to protein intake from different sources by utilising a distinct, rare dietary pattern: avoidance of animal foods for approximately half of the year according to Christian Orthodox Church fasting. Four-hundred adults, of whom 200 had been following religious fasting for a median of 15 years and 200 were non-fasters, underwent anthropometry, measurements of bone mineral density (BMD) and bone mineral content (BMC), and completed a food frequency questionnaire. Groups did not differ significantly in anthropometric measures, BMD, or BMC. Fasters had higher consumption of seafood and lower consumption of red meat, poultry-eggs, dairy products, and grains-cereals than non-fasters. Protein intake from these food groups exhibited similar differences; overall, fasters had lower protein intake than non-fasters. BMD and BMC were positively, though weakly, correlated with red meat and poultry-egg consumption. Thus, protein intake seems to play a minor (if any) role in bone health.

Abstract
Proper nutrition throughout childhood and adolescence is crucial for normal bone development. We investigated whether adherence to Christian Orthodox Church fasting is characterized by periodic avoidance of animal foods (including dairy products), since childhood affects stature or bone health in young adults. This cross-sectional study included 200 healthy men and women, aged 18-35, of whom 100 had been following religious fasting for a median of 14 years, starting at the age of 10, and 100 were non-fasters. Measurements included body height; bone mineral density and bone mineral content at the lumbar spine, right hip, left hip, right femoral neck, and left femoral neck; prevalence of bone fracture; serum biochemical parameters; food and nutrient intake; and physical activity and smoking habits. Fasters did not differ from non-fasters in anthropometric measures (including height), bone mineral density and content, or prevalence of low bone mineral density at any of the five sites measured; number of bone fractures; or serum calcium or 25-hydroxyvitamin D concentrations (P > 0.05). Fasters had lower daily calcium and protein intakes, as well as lower dairy consumption than non-fasters. Groups did not differ in physical activity, and fasters smoked less than non-fasters.Conclusion: Despite lower calcium intake and lower dairy product consumption, individuals adhering to religious fasting since childhood did not differ in height, bone mineral density and content, or prevalence of fractures from controls. Therefore, periodic abstention from dairy and, generally, animal products since childhood does not seem to compromise bone health in young adults.What is Known: • Bone health is an important determinant of overall health and longevity. • Proper nutrition throughout childhood and adolescence is crucial for normal bone development. • Adequate intake of dairy products is considered important due to their high calcium content.What is New: • Young adults with limited calcium intake and dairy product consumption, due to adherence to the fasting rules of the Christian Orthodox Church since childhood, do not differ in height or indices of bone health from non-fasting controls.
