Nutritional Package for Preventing Osteoporosis among Post-Menopausal Women –In view of bone density @article{doi:, author= {G.Anusha, V.Sujatha, R.Shalini, K.Bhaskar Reddy , S.Rajasekhar}, title= {Nutritional Package for Preventing Osteoporosis among Post-Menopausal Women –In view of bone density}, journal= {European Journal of Molecular & Clinical Medicine}, volume= {8}, number= {1}, pages= {2149-2158}, year= {2021}, publisher= {}, issn= {2515-8260}, eissn= {2515-8260}, doi= {}, abstract= {The National Osteoporosis Foundation (NOF) announced the actual and estimated number of adults aged 50 and older in the United States with osteoporosis and low bone mass (previously known as osteopenia) in 2002, (US). The estimates were based on population-based data from the National Health and Nutrition Examination Survey (NHANES)–III (1988–1994), which measured bone mineral density (BMD) at the femoral neck. According to the study, approximately 10 million Americans aged 50 and up had osteoporosis, with another 33 million having low bone mass. (a) Only the femoral neck BMD was used in these calculations since it was the only skeletal site for which nationally representative data was available.According to the study, approximately 10 million Americans aged 50 and up had osteoporosis, with another 33 million having low bone mass.The total selected members for study were non-randomlydivided into 3 groups (Group A, Group B and Group C). Quasi-experimental design method used for making an experimental design. Study was conducted on each group separately. Each study period covers 3 months’ time and 15 to 20 days for data analyses and reporting. The detailed should is provided in the table below. After observation of results, it is clearly indicating that the ionized Calcium levels, total Calcium levels and bone density is improved significant levels after consuming recommended nutritional food for three months compared to before taking nutritional food. Thus, the provided nutrient food is a good source of Calcium and improves bone strength in the post-menopausal women. Further, this is recommended that, the consumption recommended nutritional package for all the age groups to reduce the chance to get osteoporosis and bone fracture.}, keywords= {}, URL= {https://ejmcm.com/article_10571.html }, eprint= {https://ejmcm.com/article__06112c87e506bf9e9724e79ca27c979a10571.pdf }} .
