ABSTRACT
In February 2020, Coffea arabica L. grown on the coast and in the Southern Sierra Madre of the state of Oaxaca, Mexico obtained the denomination of origin. Which does not have data on color and chemical composition, the first associated with the degree of roasting and the second with lipids (17-18%), as the group of compounds responsible, in part, for flavor, consistency, and may contribute to health benefits. In the present work, color was determined on the CIE L*a*b* scale and the unsaturated fatty acids by Nuclear Magnetic Resonance (NMR) of 1H and 13C in samples of medium roasted specialty coffee from the "Pluma" coffee-growing region, Oaxaca, Mexico. The average value of L* luminosity in ground coffee was 42.1 ± 0.1 reported for a light roast. Unsaturated fatty acids were quantified from the lipid fraction of the gr1 ound grain by NMR 1H and 13C, obtaining on average the highest abundance of linoleic (41.7 ± 0.5 by 1 H and 41.24 ± 0.5 by 13C), followed by oleic (9.2 ± 0.2 by 1H and 7.4 ± 0.2 by 13C) and linolenic (1.5 ± 0.1 by H and 1.1 ± 0.2 by 13C). This study indicates that 1H and 13C NMR spectroscopy is a useful tool for the quantification of linolenic, linoleic, and oleic fatty acids by the method of key signal shifts of these acids found in lipid samples in roasted coffee grains.

Introduction: Introduction: the decision to supplement total parenteral nutrition (TPN) with emulsions of omega-3 (Ω3) eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids (FA) of marine origin is based on the clinical benefits obtained in different medical situations and surgical procedures, among which reductions in hospital stay, days of mechanical ventilation, incidence of infections and mortality stand out. However, the evidence in critically ill patients remains contradictory. Objective: the objective of this clinical trial was to analyze the effect of supplementation with EPA/DHA Ω3 FAs on clinical prognostic markers - medical, nutritional and biochemical - in critically ill patients, relating to outcome. Method: a clinical, controlled, randomized, single-center trial in 64 critically ill adult patients, of which 47 patients were randomized to receive TPN supplemented with EPA/DHA Ω3 FAs in doses of 0.1 g/kg/day (n = 23) and 0.2 g/kg/day (n = 24), compared with a historical control group with TPN without supplementation (n = 17). Clinical prognosis markers were determined at baseline and at the end of nutritional support (medical, nutritional and biochemical). Results: the two groups with supplementation showed a statistically significant reduction in mortality (p < 0.005); the clinical prognostic markers SOFA, APACHE II, SAPS 3, NUTRIC, RTL and CRS were consistent in showing a significant improvement (p < 0.005), of prognosis with doses of 0.1 and 0.2 g/kg/day of EPA/DHA Ω3 FAs, respectively. Conclusion: supplementation of parenteral nutrition with EPA/DHA Ω3 fatty acids at doses of 0.1 g and 0.2 g/kg/day improves recovery prognosis and the probability of survival in critically ill patients.
Introducción: Introducción: la decisión de suplementar la nutrición parenteral total (NPT) con emulsiones de los ácidos grasos (AG) omega-3 (Ω3) eicosapentaenoico (EPA) y docosahexaenoico (DHA) de origen marino se basa en los beneficios clínicos obtenidos en distintas situaciones médicas y quirúrgicas, entre los que destacan la reducción de la estancia hospitalaria, de los días de ventilación mecánica, de la incidencia de infecciones y de la mortalidad. Sin embargo, la evidencia en pacientes críticos aún es contradictoria. Objetivo: el objetivo de este ensayo clínico fue analizar el efecto de la suplementación con AG Ω3 EPA/DHA sobre los marcadores de pronóstico clínico: médicos, nutricionales y bioquímicos, en pacientes en estado crítico, en relación con el desenlace. Método: ensayo clínico, controlado, aleatorizado y unicéntrico en 64 pacientes adultos con condición crítica, de los cuales 47 pacientes se aleatorizaron para recibir NPT suplementada con AG Ω3 EPA/DHA a dosis de 0,1 g/kg/día (n = 23) o 0,2 g/kg/día (n = 24), comparados con un grupo de control histórico con NPT sin suplementación (n = 17). Se determinaron de manera basal y al final del soporte nutricional los marcadores de pronóstico clínico: médicos, nutricionales y bioquímicos. Resultados: los dos grupos con suplementación mostraron una reducción estadísticamente significativa de la mortalidad (p < 0,005); los marcadores de pronóstico clínico: SOFA, APACHE II, SAPS 3, NUTRIC, RTL y CRS, fueron consistentes en mostrar una mejoría significativa (p < 0,005) del pronóstico con las dosis de 0,1 y 0,2 g/kg/día de AG Ω3 EPA/DHA, respectivamente. Conclusión: la suplementación de la nutrición parenteral con ácidos grasos AG Ω3 EPA/DHA a dosis de 0,1 g y 0,2 g/kg/día mejora el pronóstico de la recuperación y la probabilidad de sobrevida en los pacientes críticos.

Lifestyle plays an important role in the development of noncommunicable diseases such as diabetes, hypertension, dyslipidemia, and obesity, in addition to a poor diet loaded with simple carbohydrates and saturated fats. This was a trial with a randomized, analytical, longitudinal, and prospective quasi-experimental design, which was divided into 2 phases: the first with healthy subjects with an age range between 18 to 30 y and normal BMI (18.5-24.9). The second phase was subjected with familial hypercholesterolemia aged between 18 to 45 y and overweight (25-29.9). For those subjects who frequently consumed vegetable oil of both Vitis vinifera L., or Persea americana L. (10 mL), they presented a significant reduction in anthropometric measures and in biochemical variables such as capillary glucose and increased HDLc. The vegetable oils of Persea americana L., and Vitis vinifera L., can act as adjuvants for the treatment of noncommunicable diseases.

The objective is the systematic review of studies published in Scielo, Redalyc, Dialnet, Web of Science, Scopus and Pubmed, related to the inclusion of fatty acids and lipid derivatives in the daily diet to prevent or delay the appearance or progression of Age-Related Macular Degeneration (AMD). The analysis of the research results consulted shows that AMD is one of the most frequent causes of blindness in subjects over 55 years of age. AMD is characterized by decreased vision, metamorphopsia, macropsies, micropsies, and central scotoma. Disease that must be diagnosed early as it can lead to irreversible blindness. Among the components of the diet that in numerous epidemiological studies have shown an association in the treatment of AMD and that are reviewed in this work are fatty acids, vitamins and carotenoids. There is ample evidence that fatty acids and lipid derivatives can be included in the diet plans of subjects with AMD.

To present a systematic review of published studies in databases such as PUBMED, REDALYC, SCIELO, DIALNET, SCOPUS, EBSCO and CONRICYT related to the role-played by the components present in the vegetable oil of grape seed (Vitis vinífera) and the prevention or delay in the onset or progression of neurodegenerative diseases. The analysis of the research revealed that neurodegenerative diseases causes alterations in consciousness or in the nervous system leading to severe damage in neuronal cells, these pathologies are considered gradual and progressive. Various syndromes manifest the degenerative diseases of the nervous system; in some of them the predominant symptom is the progressive dementia. Among the components of the diet that in numerous epidemiological studies have shown an inverse association are vitamins, minerals, carotenoids, polyunsaturated fatty acids and polyphenols, the latter being the ones addressed in this document. There is an important evidence that a nutritional support based on polyunsaturated fatty acids and antioxidants can be applied to subjects with a history of neurodegenerative conditions in order to act as neuroprotectors. This requires the determination of the nutritional benefits of these nutrients or of nutraceuticals for the health of this group of patients.

The purpose of this study was to evaluate the effect of the consumption of seed oils from Vitis vinifera and Arachis hypogaea in platelet aggregation. The initial hypothesis suggested that subjects who have consumed these seed oils undergo modified platelet aggregation. This study was performed using a pre-post test design, with a control group, and double blind. The effects of the consumption of grape seed and peanut oils were measured for platelet aggregation in clinical and laboratory tests in 30 healthy subjects. In addition to this group, a control group of 4 health subjects received no treatment with oils, just 500 mg oral administration acetylsalicylic acid for 7 days. Platelet aggregation was assessed by the Born turbidimetric method, using 3 different concentrations of adenosine diphosphate as agonists (2, 54; 1, 17; and 0, 58 µM). The study subjects had very similar results; both oils were shown to have a significant reduction in platelet aggregation. Grape seed oil showed a decrease of 8.4 ± 1% in aggregation, compared with peanut oil, which decreased aggregation by 10.4 ± 1%. The control group, taking 500 mg OD aspirin for 7 days, showed a significant decrease in platelet aggregation, similar to that of oil ingestion. Each of the oils was analyzed for fatty acids, to determine which particular acids were presents in greater levels, which could explain the reduction in platelet aggregation. The oil found to be most abundant in grape seeds was linoleic acid (omega-6), and in peanuts, it was oleic acid (omega-9). However, in fact, both acids reduced platelet aggregation. Consumption of plant oils from grape seeds and peanuts had a lowering effect on platelet aggregation, in addition to containing a high content of unsaturated fatty acids. However, omega-3, omega-6, and omega-9 fatty acids were not specifically responsible for the reductions mentioned above.

Objetivo: mostrar información revisada de manera sistemática de estudios publicados relacionados con la hipercolesterolemia familiar (HF), la nutrición y los genes que intervienen en el desarrollo de esta patología. Resultados: el análisis de los resultados de investigación consultados pone de manifiesto que la hipercolesterolemia familiar es un trastorno que se produce debido a mutaciones en genes que codifican el receptor de LDL, que se puede transmitir de forma autosómica dominante o bien autosómica recesiva. La importancia de su diagnóstico radica en que las personas afectas presentan una elevada frecuencia de enfermedad coronaria prematura, reduciéndose de forma importante su expectativa de vida. Conclusiones: no existen criterios clínicos específicos con un valor predictivo absoluto para el diagnóstico de HF; el diagnóstico genético permite demostrar defectos funcionales en el gen del receptor LDL, constituyendo la confirmación definitiva del diagnóstico, de ahí la importancia de presentar una visión genética del desarrollo de esta patología, que puede ser tratada para generaciones futuras de manera adecuada a través de la dietoterapia en la familia afectada (AU)
Objective: to show reviewed information of published studies relating to Familial Hypercholesterolemia (FH), nutrition, and genes involved in the development of this pathology. Results: an analysis showing familial hypercholesterolemia as a disorder occuring due to mutations in gene encoding of the LDL receptor, which can be transmitted as an autosomal dominant or autosomal recessive. Its diagnosis is important for those with a greater likelihood of premature coronary disease, and can significantly reduce life expectancy. Conclusions: there are no specific clinical criteria with absolute predictive value for the diagnosis of HF, Genetic diagnosis can prove functional defects in the LDL receptor gene, constituting definitive confirmation of the diagnosis, thus the importance of presenting a genetic vision of development of this disease, which can be treated adequately through diet therapy affecting future generations in the family concerned (AU)

OBJECTIVE: nutritional components such as antioxidants may modify the risk of Macular Degeneration Age-related (AMD). This article is a systematic review of published studies relating to the modification of lifestyle, nutrition and vitamin intake to prevent or delay the onset or progression of Macular Degeneration Age-related (AMD). RESULTS: the analysis of the results of research consulted shows that AMD is one of the most common causes of blindness in individuals over 55 years. AMD is characterized by decreased vision, metamorphopsias, macropsias, micropsias and central scotoma. Disease that must be diagnosed early because it can lead to irreversible blindness. Between components of the diet in many epidemiological studies have shown an inverse association with AMD and are reviewed in this paper are: vitamins (vitamin E and C), minerals (eg. zinc, selenium, manganese and copper) and carotenoids. CONCLUSIONS: there is substantial evidence that can be applied nutritional support for patients with AMD. This requires determining the nutritional benefits of these nutrients (vitamins, minerals and carotenoids) or nutraceutical foods for health in this group of patients.
Objetivo: componentes nutricionales como los antioxidantes pueden modificar el riesgo de padecer Degeneración Macular Relacionada con la Edad (DMRE). Este es un artículo de revisión sistemática de estudios publicados relacionados con la modificación del estilo de vida, la nutrición y la ingesta de vitaminas para prevenir o retrasar la aparición o progresión de la DMRE. Resultados: el análisis de los resultados de investigación consultados pone de manifiesto que la DMRE es una de las causas de ceguera más frecuentes en sujetos mayores de 55 años. La DMRE se caracteriza por disminución de la visión, metamorfosias, macropsias, micropsias y escotoma central. Es una enfermedad que debe ser diagnosticada a tiempo, ya que puede conducir a la ceguera irreversible. Entre los componentes de la dieta que en numerosos estudios epidemiológicos han mostrado una asociación inversa con la DMRE y que se revisan en este trabajo se encuentran: vitaminas (E y C), minerales (ej. zinc, selenio, manganeso y cobre) y carotenoides. Conclusiones: existe una evidencia importante de que puede aplicarse un soporte nutricional a pacientes con DMRE. Esto requiere de la determinación de los beneficios nutricionales de estos nutrientes (vitaminas, minerales y carotenoides), o bien de alimentos nutracéuticos en pro de la salud de este grupo de enfermos.
