The variety of beverages rich in vitamins A and C remains limited in our country, despite the agricultural diversity of foods rich in these nutrients, which are essential for the proper functioning of the immune system. The objective was to evaluate the acceptability of a nectar made with alfalfa, mango, and camu camu among Adventists in Lima, Peru. Methodology: Applied research, experimental, prospective, and cross-sectional design. A nectar was made using alfalfa, mango, and camu camu, its nutritional value calculated, and sensory characteristics such as odor, taste, and color were evaluated with 100 volunteers from the Seventh-Day Adventist Church in the Independencia district of Lima, Peru. Results: The nectar made from alfalfa, mango, and camu camu contains 23 mg of vitamin A and 504.26 mg of vitamin C, with 53% acceptance for color, 64% for odor, and 71% for taste among Adventists in Lima, Peru. Conclusions: The nectar provides a significant contribution of vitamins A and C, important nutrients for the immune system.

(Universidad Privada Norbert Wiener, 2024-12-13) Altamirano Rimarachín, Néstor; Espinoza Rado, Erika Paola
Objetivo General: Analizar la capacidad antioxidante y el contenido de vitamina C de la pulpa de la fruta Sanky, Corryocactus brevistylus, proveniente de dos departamentos del Perú. Material y Método: Las muestras de la fruta Sanky, Corryocactus brevistylus, fueron obtenidas de los departamentos de Arequipa y Ayacucho y trasladados en cadena de frio al laboratorio en Lima, para el análisis físico - químico. Además, para el recojo de dicho fruto, se esperó la temporada de cosecha, los meses de junio y julio 2023. Para dicho análisis físico - químico de la fruta Sanky, proveniente de dos departamentos del Perú, se plantea una hipótesis bilateral. Se quiere demostrar la diferencia significativa en ambas muestras para inferir estadísticamente los resultados mediante el uso del software estadístico RStudio. Resultados: Se determinó por medio de análisis físico-químico, la capacidad antioxidante, Vitamina C, pH y grados brix dando los siguientes resultados: Muestra de Arequipa, capacidad antioxidante: 62387 exp. En micromol de trolox/100g. y en la muestra de Ayacucho, fue en promedio 52661.9 micromol de trolox/100g. La vitamina C para la muestra de Arequipa fue de 31mg/100g. Y en la muestra de Ayacucho en promedio fue 30mg/100g. En el pH en la muestra de Arequipa fue 3.2 y la muestra de Ayacucho en promedio fue de 3.1. Finalmente, en los sólidos solubles en promedio para la muestra de Arequipa fue 5.4 y la muestra de Ayacucho fue de 5.8 respectivamente. Conclusiones: El estudio se realizó en muestra fresca de la pulpa de la fruta Sanky, Corryocactus brevistylus, según la hipótesis planteada a un 95% de confianza se infiere que hay diferencia significativa en las dos muestras de la fruta Sanky procedente de los departamentos del Perú. La capacidad antioxidante y la vitamina C es mayor en la muestra de Arequipa que en la muestra de Ayacucho. En cuanto al pH en la muestra de Arequipa es ligeramente mayor al de Ayacucho. Sólidos solubles (Grados Brix) es ligeramente mayor en la muestra de Ayacucho que el de Arequipa.

Critical review: effect of Zinc and/or vitamin C supplementation as a treatment in the recovery of patients with Covid-19
(Universidad Privada Norbert Wiener, 2022-11-21) Galarza Martel, Ronny Raúl Omar; Bohórquez Medina, Andrea Lisbet
The present work is a secondary research of critical review, which aimed to determine the effect of supplementation with zinc and/or vitamin C as a treatment for the recovery of patients with COVID-19. Evidence-Based Nutrition was used as a methodology. (NuBE), likewise, the systematic search of articles was carried out using Pubmed, Science Direct, Springer Open, Scopus and MDPI as scientific databases, where 55 articles were found, of which 17 were selected to be evaluated by the CASPe tool and in this way a randomized clinical trial titled: “Effect of high-dose zinc and ascorbic acid supplementation vs usual care on symptom length and reduction among ambulatory patients with SARS-CoV-2 infection: The COVID A to Z” was selected. randomized clinical trial", which obtained a level of evidence "I" and a grade of recommendation "Strong" based on the researcher's evaluation in accordance with the application of the CASPe tool, concluding that zinc supplementation and/or vitamin C generates a positive effect in the treatment for the recovery of patients with COVID-19, but it is not statistically significant; Therefore, larger clinical trials must be carried out to demonstrate the importance of said supplementation.

Level of knowledge about the administration of vitamin C and its relationship with the practice of nurses who provide home care in times of the Covid-19 pandemic, in Lima, 2022.
(Universidad Privada Norbert Wiener, 2022-05-20) Sanchez Urrutia, Olga Azucena; Gonzales Saldaña, Susan Haydee
In the present study "Level of knowledge about the administration of vitamin C and its relationship with the practice of nurses who provide home care in times of Covid-19 pandemic, in Lima, 2022", the objective was raised: To determine the relationship that exists between the level of knowledge about the administration of vitamin C and the level of performance in the practice of nursing staff. Methodology: The study is correlational, of an application type and non-experimental design. The population is made up of sixty (60) nursing professionals who work in House Nursing. The data collection technique was the survey and observation. The instruments that were applied were a questionnaire and an observation guide. Results: A positive and strong correlation was evident, statistically significant between the study variables with a Spearman coefficient of 0.8473959. Conclusions: It is concluded that there is a relationship between the study variables. Regarding the dimensions of generalities, dosage and situational, the correlation values amount to 0.6582887, 0.5416052 and 0.4313139 respectively. The above reflects the importance of correct conceptual management as it is directly related to the practical performance of nursing staff.
