Conservación de la remolacha (beta vulgaris) minimamente procesada mediante técnicas de corte, precocción y envasado al vacío
(2010) Arteaga Almeida, Cristina Alexandra
En virtud de que la remolacha (Beta vulgaris) en nuestro país sólo se la consume en fresco y no existe un proceso sobre la misma, motivó a realizar la investigación sobre la conservación de esta hortaliza mínimamente procesada mediante técnicas de corte, precocción y envasado al vacío, aportando con nuevas aplicaciones tecnológicas que pudieran ser aplicadas en un futuro El presente trabajo muestra la variación de la concentración de betalaína y pH en remolacha (Beta vulgaris) procesada, mediante técnicas de corte, pre cocción y envasado al vacío. El tiempo de estudio fue de 45 días en producto almacenado en refrigeración (4oC). Dentro de la metodología de análisis se evaluó la concentración de betalaína cada 72 horas, mediante técnicas espectrofotométricas a una longitud de onda de 537 nm. El pH se tomó con un pH-metro digital a intervalos de tiempo iguales. Mediante análisis estadístico se determinó que el producto presentó variación significativa en cuanto a la concentración de betalaínas en el tiempo, lo cual fue evidenciado en la prueba de comparación múltiple para concentración de betalaína donde se indica que el tratamiento que conserva la mayor cantidad de betalaína es a1b2c2 (75 minutos de precocción, corte en rodajas y envasado al vacío). Mientras que el valor de pH permaneció estable durante el tiempo de almacenamiento de 6.3 a 6.6 obteniendo que el tratamiento a3b1c2 (105 minutos de precocción, corte en cubitos y envasado al vacío) fue el más estable.

Type 2 diabetes mellitus is one of the main diseases affecting Ecuadorian society, currently impacting 1.4 million Ecuadorians. This situation is exacerbated as a result of unhealthy nutritional habits, which lead to an increase in people with overweight and obesity. It is important to highlight the increase in the older adult population with these problems, as well as the sedentary customs that contribute to the sustained rise in type 2 diabetes mellitus cases. It is a priority for health authorities to develop nutritional strategies for older adults affected by this disease, emphasizing the importance of implementing health education actions that positively impact the change of poor nutritional habits and the systematic increase of physical activity as fully viable alternatives to reduce type 2 diabetes mellitus cases in the adult population. The methodology used in the development of the scientific article corresponds to a literature review. In conclusion, nutritional strategies focus on transforming lifestyles, through increasing physical activity, reducing carbohydrate intake, and adopting a healthy nutrition rich in proteins and fiber but low in fats.

Introduction: Type II Diabetes Mellitus (T2D) is a worldwide epidemic characterized by insulin resistance, the prevalence of which is increasing. The presence of the disease together with the accumulation of visceral fat can trigger various vascular complications. Objectives: To relate body fat measured by bioimpedance with macro and microvascular complications in patients with T2D. Methodology: A descriptive, cross-sectional study was carried out with a quantitative correlational approach in a sample of 88 patients diagnosed with T2D. To evaluate body composition, the multifrequency segmental bioimpedance method was used with the equipment (Inbody S10). The variables analyzed include: total body fat in kilograms, percentage of fat, visceral fat area and body mass index; the association with the following complications was evaluated: macrovascular (stroke) and microvascular (retinopathy, nephropathy, neuropathy). Statistical analysis was performed using a Pearson coefficient, considering significant values (p < 0.05). Results: The amount of total body fat in kilograms showed a significant association with microvascular complications (r = 0.99), with a higher prevalence in women. In addition, it is highlighted that the area of visceral fat showed moderate correlations, particularly with nephropathy, indicating an association between abdominal obesity and this complication. Discussion: The results suggest that, although total fat in kilograms is an important risk indicator, the area of visceral fat is crucial to identify certain specific complications, such as nephropathy. This supports the use of bioimpedance to assess body composition in patients with T2D. Conclusion: Body fat, especially that accumulated in the visceral area, is correlated with an increased risk of vascular complications in patients with T2D, highlighting the importance of a detailed assessment of fat distribution for the prevention and treatment of these complications.

This study aimed to investigate the myths and realities related to breastfeeding (LM) that could influence its premature discontinuation. For this purpose, a systematic review of the relevant scientific literature was conducted, covering the period from 2018 to 2024. Objective: to identify, classify and differentiate between myths, beliefs and incorrect perceptions about breastfeeding, assessing their impact on mothers' decision to initiate or continue this practice. Several aspects were explored, such as mothers' concerns that could obstruct the initiation or continuation of breastfeeding, the causes of abandonment of this practice and the baby's health, nutrition myths during breastfeeding. The methodology employed included the application of advanced bibliographic techniques for the extraction of data from a variety of sources, including books, specialized journals, and both qualitative and quantitative empirical studies, in addition to the analysis of specific cases, of which there were a total of 37. The results highlight the importance of debunking myths about breastfeeding through evidence-based education at both prenatal and postnatal stages, actively promoting breastfeeding in communities, implementing policies that support its practice, and ensuring the creation of supportive environments that foster this essential practice.

This research paper highlights the prevalence of malnutrition in institutionalized older adults in the Ambato canton, focusing on risk factors, dietary intake, and nutritional status. Malnutrition in this age group is a public health problem influenced by socioeconomic, genetic, lifestyle, and dietary factors, all of which are exacerbated by the growing aging population and inadequate care. Identifying these issues is challenging, as diagnoses are often made too late. The study conducted is cross-sectional with both quantitative and qualitative approaches, evaluating 50 older adults from two institutions through body perimeter measurements, body mass index (BMI), and the Mini Nutritional Assessment (MNA) survey. The main risks found include social isolation, stress, functional dependency, depression, and poor dietary intake. The results showed that 50% of the population is underweight, 58% are at risk of malnutrition, and 22% are already affected by it, due to insufficient calorie intake and low weight, with no significant correlation with muscle mass or body fat. Malnutrition in older adults is not solely related to the amount of energy consumed, but also to the quality of their diet, physical activity, and emotional support. Therefore, it is recommended to promote physical activity, encourage social and psychological support to ensure a better quality of life for the vulnerable population.

Type 2 diabetes mellitus (T2DM) is a metabolic disease characterized by elevated glucose levels, which over time can cause severe vascular complications such as retinopathy, nephropathy, and cerebrovascular accident (CVA). Body composition, particularly lean mass, fat-free mass, and skeletal muscle mass is a key factor in preventing these complications. This study evaluated the relationship between body composition, measured by bioimpedance, and vascular complications in T2DM patients. Methods. A quantitative, correlational, and multivariate study was conducted with 88 T2DM patients aged 18 to 90 years from diabetes clubs in the province of Tungurahua. Bioimpedance (Inbody S10) was used to measure body composition. Data were analyzed using descriptive statistics, Pearson correlation, and principal component analysis with SPSS. Results. The results showed that lean mass and fat-free mass decreased significantly with age, which correlates with a higher risk of vascular complications. Skeletal muscle mass had a weaker correlation with complications, especially in the case of retinopathy. Microvascular complications, such as neuropathy and nephropathy, were more related to lean mass and fatfree mass. Conclusions. Preserving lean mass and fat-free mass are critical factors for reducing the risk of vascular complications in T2DM patients. Physical exercise and proper nutrition are suggested to maintain a healthy body composition, especially in older adults, as a key strategy to prevent microvascular and macrovascular complications

Introduction: bluten is a protein present in grains such as wheat, barley and rye which provides elasticity and structure to baked products, however, worldwide there are people with celiac disease or non-celiac gluten sensitivity and because the body does not assimilate this protein it is necessary to avoid it, therefore currently there is a growing demand for gluten-free foods creating new products, improving their nutritional profile and market acceptance. Due to the above mentioned, the objective of this work is to carry out a bibliographic search of current trends and technological advances in the development of gluten-free products, in order to identify opportunities for innovation and improvement in the quality and acceptability of these products among consumers. Method: to carry out the research, a bibliographic review was carried out in PUBMED, WEB OF SCIENCE, SCIENCEDIRECT, SCOPUS and GOOGLE SCHOLAR related to the topic of interest, including information found within the last five years (2019 - 2024). Results: thus, it is concluded that there are currently a huge number of gluten-free products, especially bakery products, with a change in nutritional composition. Likewise, advances propose the use of substitute flours for the preparation of gluten-free foods, creating greater accessibility of these products to their consumers. Conclusions: finally, it is concluded that the consumption of these foods should be in moderation due to their nutritional value to avoid deficiencies and non-communicable diseases in the long term.
