Adequate Calcium Intake Research Articles

Nutrition and Osteoporosis Prevention.

Osteoporosis affects 50% of women and 20% of men after the age of 50. Fractures are associated with significant morbidity, increased mortality and altered quality of life. Lifestyle measures for fragility fracture prevention include good nutrition including adequate protein and calcium intakes, vitamin D sufficiency, and regular weight bearing physical exercise. Dietary protein is one of the most important nutritional considerations as it affects bone mineral density, trabecular and cortical microstructure, and bone strength. When calcium intake is sufficient, higher dietary protein intake is associated with lower risk of fracture. Dairy products are a valuable source of calcium and high quality protein. Dairy product consumption, particularly fermented dairy products, are associated with a lower risk of hip fracture and vegan diets are associated with increased fracture risk. Other dietary factors associated with reduced fracture risk include at least 5 servings per day of fruits and vegetables, regular tea drinking, adherence to a Mediterranean diet and other dietary patterns which provide fibers, polyphenols and fermented dairy products. Such dietary patterns may confer health benefits through their effect on gut microbiota composition and/or function. A balanced diet including minerals, protein, fruits and vegetables is an important element in the prevention of osteoporosis and of fragility fracture.

Current concept of osteoporosis diagnosis and treatment in children

Osteoporosis (OP) is a disease characterized by a decrease in bone strength, leading to an increased risk of fractures. Bone fragility in children may be due to genetic disorders, chronic underlying conditions or taking medications that negatively affect bone metabolism. The article considers the modern classification of OP in children, approaches to its diagnosis, the role of dual-energy X-ray absorptiometry for diagnosis.The main goal of OP prevention and treatment is to achieve a higher peak of bone mass, improve bone microarchitectonics, and, as in adults, reduce the risk of fractures, prevent skeletal deformities, improve mobility, independence and quality of life. Recommendations for lifestyle changes are presented, including adequate calcium intake and vitamin D, taking antiresorptive drugs, as well as prospective management of children with OP.

Maternal Dietary Intakes and Risk of Spontaneous Abortion: A Systematic Review

Background: The loss of a fetus before the 20th week of pregnancy is known as spontaneous abortion (SA). Objective: This systematic review aimed to evaluate the results of previous studies about the dietary intake of mothers who suffered from SA. Methods: We conducted a comprehensive search in the Web of Science, Cochrane, PubMed, ProQuest, Google Scholar, Science Direct, and Scopus databases to collect relevant published studies between 1990 and November 2022. The data from case-control and cohort studies that had assessed dietary intakes before and during pregnancy of women with SA were included. Results: High consumption of butter increases the risk of SA, but a very low intake of olive oil and omega-3 fatty acids can reduce the risk of SA. In addition, an adequate intake of high-quality proteins and calcium from dairy products and enough intake of fiber and phytochemicals from chocolate, fresh fruits, and vegetables can reduce the risk of SA. A number of mechanisms, such as providing essential nutrients for fertilization and implantation, promoting fetal growth, reduction of inflammatory conditions, and insulin resistance, have been proposed to explain the protective effects of these food groups against SA. Conclusion: An unhealthy diet and eating sufficient amounts of these food groups will be helpful and recommended.

Nutrition, Vitamin D, and Calcium in Elderly Patients before and after a Hip Fracture and Their Impact on the Musculoskeletal System: A Narrative Review.

Hip fractures are a major health issue considerably impacting patients' quality of life and well-being. This is particularly evident in elderly subjects, in which the decline in bone and muscle mass coexists and predisposes individuals to fall and fracture. Among interventions to be implemented in hip fractured patients, the assessment and management of nutritional status is pivotal, particularly in subjects older than 65. Nutrition plays a central role in both primary and secondary preventions of fracture. An adequate protein intake improves muscle mass and strength and the intestinal absorption of calcium. Other nutrients with recognized beneficial effects on bone health are calcium, vitamins D, K, and C, potassium, magnesium, folate, and carotenoids. With reference to calcium, results from longitudinal studies showed that the consumption of dairy foods has a protective role against fractures. Moreover, the most recent systematic reviews and meta-analyses and one umbrella review demonstrated that the combination of calcium and vitamin D supplementation significantly reduces hip fracture risk, with presumed higher efficacy in older and institutionalized subjects. Owing to these reasons, the adequate intake of calcium, vitamin D, protein, and other macro and micronutrients has been successfully implemented in the Fracture Liaison Services (FLSs) that represent the most reliable model of management for hip fracture patients. In this narrative review, papers (randomized controlled trials, prospective and intervention studies, and systematic reviews) retrieved by records from three different databases (PubMed, Embase, and Medline) have been analyzed, and the available information on the screening, assessment, and management of nutritional and vitamin D status and calcium intake in patients with hip fractures is presented along with specific prevention and treatment measures.

Nutraceuticals and Functional Foods: A Comprehensive Review of Their Role in Bone Health.

Bone health is the result of a tightly regulated balance between bone modeling and bone remodeling, and alterations of these processes have been observed in several diseases both in adult and pediatric populations. The imbalance in bone remodeling can ultimately lead to osteoporosis, which is most often associated with aging, but contributing factors can already act during the developmental age, when over a third of bone mass is accumulated. The maintenance of an adequate bone mass is influenced by genetic and environmental factors, such as physical activity and diet, and particularly by an adequate intake of calcium and vitamin D. In addition, it has been claimed that the integration of specific nutraceuticals such as resveratrol, anthocyanins, isoflavones, lycopene, curcumin, lutein, and β-carotene and the intake of bioactive compounds from the diet such as honey, tea, dried plums, blueberry, and olive oil can be efficient strategies for bone loss prevention. Nutraceuticals and functional foods are largely used to provide medical or health benefits, but there is an urge to determine which products have adequate clinical evidence and a strong safety profile. The aim of this review is to explore the scientific and clinical evidence of the positive role of nutraceuticals and functional food in bone health, focusing both on molecular mechanisms and on real-world studies.

Role of Nutrition in the Management of Patients with Multiple Endocrine Neoplasia Type 1.

Multiple endocrine neoplasia type 1 (MEN1) is a rare syndrome caused by inactivating mutations in the MEN1 tumor suppressor gene. The three main clinical manifestations of MEN1 are primary hyperparathyroidism (PHPT), duodenal-pancreatic neuroendocrine tumors (DP-NETs) and anterior pituitary tumors. Endocrine tumors in patients with MEN1 differ from sporadic tumors because of their younger age at onset, common multiple presentations and the different clinical course. MEN1 is characterized by a complex clinical phenotype; thus, patients should be followed by a multidisciplinary team of experts that includes an endocrinologist, a surgeon, a oncologist, a radiotherapist, and not least, a nutritionist. It is important to remember the fundamental role that diet plays as a primary prevention tool, together with a healthy and active lifestyle in preventing osteoporosis/osteopenia and reducing the risk of developing kidney stones due to hypercalciuria, two frequent clinical complications in MEN1 patients. Is very important for MEN1 patients to have an adequate intake of calcium, vitamin D, magnesium and phosphate to maintain good bone health. The intake of foods containing oxalates must also be kept under control because in combination with calcium they concur to form calcium oxalate crystals, increasing the risk of nephrolithiasis. Another aspect to consider is the management of patients with pancreatic neuroendocrine tumors undergoing major surgical resections of the pancreas that can lead to alterations in digestion and absorption mechanisms due to partial or total reduction in pancreatic enzymes such as amylase, lipase, and protease, resulting in malabsorption and malnutrition. Therefore, the nutritionist's aim should be to devise a dietary plan that takes into consideration each single patient, educating them about a healthy and active lifestyle, and accompanying them through various life stages by implementing strategies that can enhance their quality of life.

Abstract 7305: Chemoprevention of colorectal cancer: Role of trace minerals in conjunction with calcium

Abstract Background: Colorectal cancer (CRC) is a leading cause of cancer-related deaths worldwide. CRC usually develops from adenomas (CRC precursors) after a long latency period. Prevention is crucial in reducing CRC incidence and progression to cancer. Among several prevention options, calcium has been a widely considered chemo-preventative agent. Aims: Calcium plays a vital role in the regulation of epithelial cell differentiation, which is essential for epithelial growth control. Epidemiological studies have demonstrated that adequate calcium intake is crucial for protection against colonic polyp formation and colorectal cancer. However, recent interventional trials with calcium have had only modest and mixed results, and the question is how to improve efficacy. One potential strategy is to use calcium in combination with additional minerals and trace elements. Results: Our preclinical studies employing monolayer cultures with CRC cell lines and colon organoids cultures from colon polyps have shown that a calcium-rich mineral combination derived from fossilized red algae (Aquamin) is more effective than calcium alone in inducing differentiation, suppressing growth and upregulation of calcium-sensing receptor. When colonic adenomas in culture were subjected to differential proteomic analysis, Aquamin upregulated several proteins involved in proliferation suppression, DNA mismatch repair and inducing differentiation, and apoptosis. Two long-term mouse studies have demonstrated that Aquamin is more effective in suppressing polyp & CRC incidence compared to calcium alone. Based on these findings, we conducted a 90-day FDA-approved trial (a pilot study with ten subjects per arm) comparing the two interventions in human subjects at risk for CRC. Results showed that Aquamin treatment reduced proliferation and increased cell differentiation observed by immunohistochemistry. Proteomic analysis also revealed that the minerals upregulated several proteins related to growth suppression, inducing differentiation and those contributing to cell-cell and cell-matrix adhesion functions and downregulated proteins involved in proliferation and nucleic acid metabolism. Conclusion: These results provide convincing evidence that a multi-mineral combination derived from red algae can provide benefits in preventing CRC that are not seen with calcium alone. Further studies, such as a polyp-prevention trial in human subjects, are warranted to advance these CRC prevention efforts.

DSOG Guideline Bulletin: Vegetarian and vegan diets during pregnancy

Vegetarian and vegan diets are becoming increasingly common among Danish women of reproductive age. We reviewed the available literature via PubMed and concluded that varied and well-balanced vegetarian and vegan diets are safe and sufficient during pregnancy and lactation, provided that dietary supplements for folate, vitamin B12, and vitamin D are taken regularly. Additionally, it is important to ensure adequate intake of calcium, protein, and iron. Protein requirements may be higher for vegetarians and especially for vegans, though evidence is limited regarding the recommendation for increased protein intake if the diet is exclusively plant-based. Routine blood tests are not recommended unless there has been insufficient supplementation leading up to or during pregnancy, or if symptoms suggest a deficiency. We found no evidence to support supplementation with docosahexaenoic acid (DHA). There is no indication of an increased risk of malformations for pregnant Danish women on a vegetarian or vegan diet compared to omnivores. The risk of delivering small for gestational age and low birthweight infants (<2500 grams) may be increased, but the evidence is conflicting and of poor quality. Vegetarian and vegan diets may offer benefits, such as a lower risk of excessive gestational weight gain and women consuming the lowest amounts of meat have a significantly lower risk of gestational diabetes. Vegans may face a lower risk of having large for gestational age infants. Vegetarian and vegan lifestyles are also compatible with breastfeeding, and provided women take the recommended supplements, there is no difference in the micronutrient content of the breast milk of vegetarian/vegan women compared to that of omnivores. Children of vegans and vegetarians with limited or no consumption of milk products or eggs are recommended to breastfeed or receive baby formula for at least the first two years of life.

Effects of Daidzein, Tempeh, and a Probiotic Digested in an Artificial Gastrointestinal Tract on Calcium Deposition in Human Osteoblast-like Saos-2 Cells.

Adequate calcium intake is crucial for the prevention and treatment of bone-related issues. Developing a nutritional source of readily bioavailable calcium is particularly significant for individuals deficient in this essential element and at risk of developing osteoporosis. This research aimed to evaluate the impact of tempeh (T), daidzein (D), and Lactobacillus acidophilus (LA) within a simulated intestinal environment consisting of Caco-2 epithelial and Saos-2 cells, focusing on their implications for bone mineralization mechanisms. In the initial phase, calcium bioaccessibility from calcium citrate (CaCt), LA, D, the daidzein combination D-CaCt-LA (D1:1:1), and the tempeh combination T-CaCt-LA (T1:1:1) was assessed through digestion simulation. The calcium content of both untreated and digested samples was determined using atomic absorption spectrometry (AAS). In the subsequent stage, the digested samples were used to induce intestinal absorption in differentiated enterocyte-like Caco-2 cells. The permeable fractions were then evaluated in a culture of osteoblast-like Saos-2 cells. Preliminary cellular experiments employed the MTT assay to assess cytotoxicity. The results indicated that the analyzed products did not influence the deposition of extracellular calcium in Saos-2 cells cultured without mineralization stimulators. The combined formulations of permeable fractions of digested CaCt, LA, D, and T demonstrated the capacity to enhance the proliferation of Saos-2 cells. In Saos-2 cells, D, D1:1:1, and LA showed no discernible impact on intracellular calcium accumulation, whereas T and T1:1:1 reduced the calcium deposits. Additionally, mRNA transcripts and alkaline phosphatase (ALP) activity levels in Saos-2 cells cultured without mineralization induction were unaffected by the analyzed products. An examination of the products revealed no discernible effect on ALP activity or mRNA expression during Saos-2 cell differentiation. Our findings suggest that tempeh, daidzein, and L. acidophilus did not positively impact cellular calcium deposition in Saos-2 cells. However, tempeh, daidzein and its combination, and L. acidophilus might enhance the process of osteogenic differentiation in Saos-2 cells. Nevertheless, this study did not identify any synergistic impact on calcium deposition and the process of osteogenic differentiation in Saos-2 cells of isoflavones and probiotics.

Improving health indicators of mothers and newborns by empowering communities in urban slums of Mumbai, Maharashtra, India

Abstract Background: Newborns represent the most vulnerable segment of our society, constituting nearly 30% of all under-5 mortality cases. Despite well-established healthcare systems in metropolitan areas, urban slum dwellers, comprising approximately 50%–60% of the population, often lack access to these services. The Society for Nutrition, Education, and Health Action (SNEHA) operates within urban slums, aiming to enhance health outcomes for mothers and children. At SNEHA, we firmly believe that a healthy society starts with the well-being of mothers and infants. Our organization is dedicated to empowering communities to improve the health status of newborns in urban slums. Material and Methods: As part of the intervention, 7819 households with a population of 35,000 were targeted. SNEHA’s field workers conducted regular visits to these households, providing counseling on breastfeeding immunization and identifying potential health risks. Married women of reproductive age were specifically identified and consistently educated about the significance of early pregnancy registration. Pregnant women received support for registering their pregnancies, attending regular antenatal care (ANC) check-ups, adhering to ANC visit schedules, and maintaining adequate iron, calcium, and nutrition intake. Additionally, they were informed about the advantages of institutional delivery and encouraged to prepare for childbirth. Mothers of children under 2 years were urged to bring them to primary health centers for routine immunizations. Furthermore, they were advised on contraception methods to ensure proper spacing between children. Results: Our endeavors have resulted in a 34% rise in early pregnancy registration, a 22% increase in the number of women attending four antenatal check-ups, an 11% uptick in institutional deliveries, a 24% improvement in exclusive breastfeeding rates, and a notable 67% surge in the prevalence of contraception. Conclusion: Our intervention has proven that it is possible to improve the health indicators of women and children through behavior change communication, regular home visits, and community awareness.

Examining The Relationship Between Children's Dietary Patterns and The Development of Dental Problems

Background: This cross-sectional study explores the relationship between children's dietary patterns and the development of dental problems in a sample of 200 participants aged 6 to 12 years. Recognizing the critical role of nutrition in pediatric oral health, the study aims to identify associations between dietary habits, nutrient intake, and prevalent dental issues. Methods: Dietary patterns were assessed using a Food Frequency Questionnaire (FFQ), and nutrient intake was analyzed. Clinical examinations by trained dental professionals evaluated dental problems, including caries, enamel erosion, and malocclusions. Statistical analyses, including logistic regression, were employed to examine associations between dietary patterns and dental outcomes. Results: Demographic characteristics indicated a balanced sample with equal gender distribution and representation across age groups. Analysis of dietary patterns revealed mean values within recommended ranges for caloric intake, protein, carbohydrates, fat, and calcium. Significant associations were found between high sugar consumption and dental caries, low calcium intake and enamel erosion, and irregular snacking habits and malocclusions Conclusion: This study underscores the importance of understanding the intricate relationship between children's dietary patterns and dental health. The identified associations provide insights for targeted interventions aimed at reducing sugar consumption, promoting adequate calcium intake, and addressing irregular snacking habits to enhance pediatric oral health.

The influence of zinc and iron intake on osteoarthritis patients' subchondral sclerosis progression: A prospective observational study using data from the osteoarthritis Initiative

ObjectiveThe purpose of this investigation was to elucidate the relationship between the zinc and iron intake and the advancement of subchondral sclerosis among patients with osteoarthritis (OA). The goal was to establish personalized, nutritionally-informed strategies designed to retard the progression of subchondral sclerosis and conserve joint structure. MethodsFor the purposes of this research, we derived data from the Bone Ancillary Study (BAS), a constituent study of the Osteoarthritis Initiative (OAI). The intake of zinc and iron was evaluated via a food frequency questionnaire. Magnetic Resonance Imaging trabecular morphometry was employed to ascertain the microarchitecture of the subchondral bone. For the analysis of collected data, we employed logistic regression along with generalized additive models (GAMs). ResultsThe participant cohort was comprised of 474 OA patients (216 females, 258 males, mean [SD] age 64.1[9.2]). Notably, an increment in zinc consumption was linked with a significantly reduced likelihood of deterioration in Tb.N (OR = 0.967, 95 % CI, 0.939–0.996, P-value = 0.026), Tb.Th (OR = 0.958, 95 % CI, 0.929–0.989, P-value = 0.008), and Tb.Sp (OR = 0.967, 95 % CI, 0.939–0.996, P-value = 0.013). An elevation in iron intake seemed to enhance the risk of subchondral sclerosis, as indicated by the GAM. Subgroup analysis revealed an interaction between the effectiveness of zinc intake and factors such as gender, age, radiographic severity, and macronutrient consumption. An increased intake of calcium amplified the beneficial impact of zinc on subchondral sclerosis. ConclusionsOur findings indicate a positive association between elevated zinc intake and a slowdown in the progression of subchondral sclerosis in OA patients, notably among females, middle-aged individuals, and those with higher calcium and magnesium intake. Conversely, a higher iron intake might intensify subchondral sclerosis. These results suggest that personalized, diet-based interventions focusing on zinc consumption, in tandem with adequate calcium intake, could potentially decelerate the progression of subchondral sclerosis in individuals afflicted with OA.

Calcium food sources in primary school children with low calcium intakes in Kuala Lumpur.

Background: Adequate calcium intake at an early age is crucial to achieving peak bone mass. Nevertheless, low calcium intake is common in Malaysian children. Aim: This study examined the calcium food sources and factors associated with low calcium intake among 243 children aged 9-11 years in Kuala Lumpur. Methods: Diet histories and bone density were measured. Results: The mean calcium intake was 370 ± 187 mg/day. The main contributors to calcium intake were beverages (19.2%), cereal (18.6%), milk and dairy (13.0%), meat and poultry (12.9%), and fish and seafood (10.1%). Within each food group, calcium-contributing foods tend to be from low bioavailability sources such as rice, cocoa-based and malted drinks, and chicken rather than milk. Children who practised regular meals, ate breakfast and snacks and consumed milk more than one serving daily have a higher calcium intake. Conclusion: In conclusion, public health strategies to improve the status of low calcium intake and poor choices of calcium-rich foods are needed to optimise bone health in this population.

Total Calcium Intake Is Associated With Trabecular Bone Density in Adolescent Girls With Type 1 Diabetes.

Type 1 diabetes (T1D) confers an increased risk of fracture and is associated with lower bone mineral density (BMD) and altered microarchitecture compared with controls. Adequate calcium (Ca) intake promotes bone mineralization, thereby increasing BMD. The objective of this analysis was to evaluate the associations of total daily Ca intake with bone outcomes among youth with T1D. This was a cross-sectional analysis of girls ages 10-16 years with (n = 62) and without (n = 60) T1D. We measured Ca intake with a validated food-frequency questionnaire and BMD, microarchitecture, and strength estimates with dual-energy X-ray absorptiometry and high-resolution peripheral quantitative computed tomography. Total daily Ca intake did not differ between groups (950 ± 488 in T1D versus 862 ± 461 mg/d in controls, p = 0.306). Serum 25OHD was lower in T1D (26.3 ± 7.6 versus 32.6 ± 9.0 ng/mL, p = <0.001), and parathyroid hormone (PTH) was higher in T1D (38.9 ± 11 versus 33.4 ± 9.7 pg/mL, p = 0.004). Trabecular volumetric BMD and thickness at the tibia were lower in T1D (p = 0.013, p = 0.030). Ca intake correlated with trabecular BMD at the radius and tibia among T1D participants (β = 0.27, p = 0.047, and β = 0.28, p = 0.027, β = 0.28, respectively) but not among controls (pinteraction = 0.009 at the radius, pinteraction = 0.010 at the tibia). Similarly, Ca intake was associated with estimated failure load at the tibia in T1D but not control participants (p = 0.038, β = 0.18; pinteraction = 0.051). We observed the expected negative association of Ca intake with parathyroid hormone in controls (p = 0.022, β = -0.29) but not in T1D participants (pinteraction = 0.022). Average glycemia as measured by hemoglobin A1c did not influence the relationship of Ca and PTH among participants with T1D (pinteraction = 0.138). These data suggest that youth with T1D may be particularly vulnerable to dietary Ca insufficiency. Increasing Ca intake may be an effective strategy to optimize bone health in this population. © 2023 The Authors.

Knowledge of Osteoporosis among women of 40 years and above in Nepalgunj sub-Metropolitan City

Background: Osteoporosis is a global problem with a lifetime risk of osteoporotic fractures in women. It is the condition that reduces bone mass per unit volume of normally mineralized bone resulting in fractures, even minor trauma which increases as an increase in age. Objectives: The study aimed to assess the osteoporosis knowledge among women of 40 years and above residing in Muktipur-12, Nepalgunj, Banke. Methods: A quantitative cross-sectional study was carried out in Muktipur-12, Nepalgunj Sub Metropolitan city among 150 women of 40 years and above. Face to face interview was conducted during July-August, 2018. Statistical Package for the Social Sciences (SPSS) version-16 was used for descriptive and inferential statistics. Results: Study showed 61.3% women of 40 years and above had fair knowledge of osteoporosis. Personal presence of osteoporosis was reported by 26% of respondents. Diet low in calcium (79.3%), lack of exercise (57.3%) and personal history of fracture as an adult (44.7%) were the major reported causes of osteoporosis. Regarding knowledge on symptoms, lower back pain (78%), stooped position (64.7%) and bone fracture (42.7%) were reported. More than three fourth (84%) answered adequate calcium intake as preventive measures for osteoporosis. Knowledge of osteoporosis was found to be significantly associated with age (p&lt;0.001), literacy (p=0.028) and occupation (p=0.019) of the participants. Conclusion: Study concluded fair level of knowledge regarding osteoporosis. Osteoporosis awareness program need to be continued and expanded covering young age women which could minimize the future risk of osteoporosis.

HUBUNGAN ASUPAN ZAT BESI DAN KALSIUM DENGAN KEJADIAN DISMENORE PADA REMAJA PUTRI

One sign of reproductive maturity in young women is the arrival of menstruation or menstruation (menarche). A common menstrual disorder is painful menstruation (dysmenorrhea), especially during adolescence. The incidence of dysmenorrhea in the world is quite high. The prevalence of menstrual pain in Indonesia consists of 54.89% primary dysmenorrhea and 9.36% secondary dysmenorrhea. If left untreated, dysmenorrhea can develop into pathological conditions, including infertility. Dysmenorrhea that every woman experiences is different, some are a little annoying, but some are unable to carry out activities. Many nutrients, such as magnesium, calcium, vitamin E, and iron, have also been linked to dysmenorrhea. Adequate intake of calcium and iron is believed to reduce dysmenorrhea. The purpose of this study was to determine the relationship between intake of iron and calcium with the incidence of dysmenorrhea in young women at SMP Negeri 16 Padang. This research uses observational analytic method with cross sectional design. The sample in this study were 39 young women (grade IX students) using a proportional random sampling technique. Researchers used a menstrual questionnaire and a 24-hour food recall form. This research was conducted from July to September 2022. The research results were processed using the chi square statistical test. From a study conducted on 39 respondents, it was found that most respondents (61.5%) experienced dysmenorrhea, 30.8% of respondents had insufficient iron intake and most (87.2%) had calcium intake that was less than the adequacy rate. daily minimum nutrition. The results of the bivariate test found that there was no relationship between iron (Fe) intake and the incidence of dysmenorrhea (p value 0.083) and there was no relationship between calcium intake and the incidence of dysmenorrhea in young women at SMPN 16 Padang with p value = 0.062. Adolescent girls should still pay attention to iron and calcium intake in their daily consumption because if the intake is insufficient it can increas.e the risk of dysmenorrhea.

The effects and predictive value of calcium and magnesium concentrations on nutritional improvement, inflammatory response and diagnosis in patients with Crohn's disease.

Crohn's disease (CD) is a progressive inflammatory disease of the gastrointestinal tract associated with malnutrition, high levels of inflammation and calcium and magnesium deficiencies. However, the relationships between these symptoms are poorly defined. Seventy-six adult CD patients who had not yet started treatment and 83 healthy volunteers were recruited. The dietary intakes, serum calcium and magnesium levels, nutritional indicators and biochemical markers of disease activity were measured. Most participants had inadequate magnesium and calcium intake. The serum magnesium and calcium levels, as well as nutritional and inflammatory indicators, differed significantly between CD patients and controls, especially in the active phase. Serum levels of magnesium and calcium correlated with both nutritional status and inflammation. The cut-off values for CD development were 0.835 mmol/L (magnesium) and 2.315 mmol/L (calcium), whereas those for the active phase were 0.785 and 2.28 mmol/L, respectively. Adequate intake of magnesium and calcium may both improve the nutritional status of CD patients and reduce inflammation, benefiting disease relief. As both magnesium and calcium reflect CD status, they may be useful markers for CD diagnosis and disease activity.

Bone, Estrogen, Strength Training Study Translation to Osteoporosis Prevention Research and Education

ABSTRACT Introduction/Purpose: Osteoporosis is a bone disease that a combination of exercise, hormone replacement therapy (HT), and calcium intake may help prevent by preserving or increasing bone mineral density (BMD) in postmenopausal women. The Bone, Estrogen, Strength Training (BEST) Study clinical trial was designed to determine the effects of exercise training on BMD in postmenopausal women either with or without HT. Methods: The BEST Study was unique because it included progressive resistance and weight-bearing exercises, addressed HT use, supplemented and documented calcium intake, provided robust intervention support, and extended the intervention protocol for multiple years. Results: The study findings demonstrated that postmenopausal women who had adequate calcium intake and followed the BEST exercise program maintained or increased their BMD. This article describes key lessons learned from the longitudinal BEST Study for translating the findings to the research community to improve future intervention research studies and to health professionals to inform osteoporosis prevention and bone health education. The BEST Study produced five lessons that can inform and improve osteoporosis prevention research and educational practice: 1) long-term bone health effects are important to study and require proactive strategies to obtain longitudinal funding support, 2) long-term retention of participants and compliance with study protocols require a participant focused study design and protocols, 3) extensive documentation of intervention protocols and sophisticated analytical strategies are essential to determine study intervention effects, 4) heterogeneity in responses to research study interventions should be expected and explored, and 5) osteoporosis prevention can be facilitated by translating the positive results from the BEST Study into practical educational tools. Conclusion: The BEST Study results can be translated into effective exercise and dietary practices to help prevent osteoporosis. Future research studies that use participant motivation and support protocols and meticulous documentation will further advance research in the prevention of osteoporosis.

Including calcium-fortified water or flour in modeled diets based on local foods could improve calcium intake for women, adolescent girls, and young children in Bangladesh, Uganda, and Guatemala.

Adequate calcium intake is essential for health, especially for infants, children, adolescents, and women, yet is difficult to achieve with local foods in many low- and middle-income countries. Previous analysis found it was not always possible to identify food-based recommendations (FBRs) that reached the calcium population recommended intake (PRI) for these groups in Bangladesh, Guatemala, and Uganda. We have modeled the potential contribution of calcium-fortified drinking water or wheat flour to FBR sets, to fill the remaining intake gaps. Optimized diets containing fortified products, with calcium-rich local foods, achieved the calcium PRI for all target groups. Combining fortified water or flour with FBRs met dietary intake targets for adolescent girls in all geographies and allowed a reduction from 3-4 to the more feasible 1-2 FBRs. Water with a calcium concentration of 100mg/L with FBRs was sufficient to meet calcium targets in Uganda, but higher concentrations (400-500mg/L) were mostly required in Guatemala and Bangladesh. Combining calcium-fortified wheat flour at 400mg/100g of flour and the FBR for small fish resulted in diets meeting the calcium PRI in Bangladesh. Calcium-fortified water or flour could improve calcium intake for vulnerable populations, especially when combined with FBRs based on locally available foods.

High Calcium Boba from Egg Shells to Prevent Stunting and Boost the Immune System

Nutritional status and stunting are problems in several countries, including Indonesia. Calcium is one of the important micronutrients to prevent stunting, and the immune system can act as a second messenger of lymphocytes to maintain the body's immune response. Calcium in eggshells can be processed into boba which is popular in the community. This study aims to examine eggshells as a high-calcium food source to prevent stunting and help increase immunity. This research is a Literature Review of open access articles published in 2016 - 2021 on Google Scholar, PubMed, and Science Direct. Duplicate reports were excluded from the study. The keywords used in searching the journal in the database are eggshells, calcium, stunting, immune system, and popular foods. Research shows that every gram of eggshell contains 381 mg of calcium. Adequate calcium intake supports increasing height, maintaining bone health, and preventing stunting. Increased intracellular calcium is essential for the steps of intracellular signaling that induce proliferation, cytokine production, and regulation of several transcription factors. Eggshells can be safely consumed if they are kept for 20 minutes and finely ground with the high calcium content. High calcium boba from eggshell flour can prevent stunting and boost the immune system.
