Consecuencias en la salud humana del uso de las tecnologías de producción de aceites vegetales refinados de semillas / Consequences of the technologies of production of refined vegetable oils of seeds on human health

Introducción: La producción y consumo de aceites vegetales refinados ha incrementado de manera notable en los últimos años a nivel mundial a la vez que han aumentado determinadas enfermedades crónicas no transmisibles. En sus inicios estos productos se recomendaban como saludables y sustitutos de grasas animales, pero con el paso de los años y el avance científico que conlleva se publicaron varios estudios que cuestionan dichas recomendaciones al encontrar posibles problemas para la salud relacionado con su ingesta. Objetivo: Evidenciar los impactos negativos que han tenido sobre la salud el uso de estas tecnologías en el campo de la nutrición humana. Métodos: Se realizó una búsqueda de artículos en Pubmed y Google Académico, con las palabras clave: Aceites refinados, enfermedades crónicas no transmisibles, inflamación, riesgo. Conclusiones: La producción actual de aceites vegetales refinados procedentes de semillas representa un serio riesgo a la salud humana al estar correlacionado con diversas enfermedades(AU)

Introduction: Production and consumption of refined vegetable oils have notably increased worldwide in recent years, and so has increased the occurrence of a number of chronic non-communicable diseases. Initially, these products were recommended as healthy substitutes for animal fats, but with the passing of time and the consequent advancement of science, several studies have been published which question the worth of such recommendations in the light of potential risks to health related to vegetable oil consumption. Objective: Describe the negative impact of the use of these human nutrition technologies on health. Methods: A search was conducted for papers about the topic published in the databases PubMed and Google Scholar. The search words used were refined oils, chronic non-communicable diseases, inflammation, risk. Conclusions: Current production of refined vegetable oils from seeds is a serious risk to human health, being as it is correlated to various diseases(AU)

Chemical compositions and antioxidant activity of Heracleum persicum essential oil

ABSTRACT In this study essential oil of the aerial parts of Heracleum persicum a spice widely used in Iran was isolated by conventional hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD) techniques. The extraction yield was determined and the chemical compositions of essential oils were identified by the application of gas chromatography/mass spectrometry (GC/MS). The antioxidant activity was determined by two different methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and oven test methods. Although the main compounds of essential oils by the both extraction methods were similar, the essential oil extracted by HD with lower extraction efficiency showed more diverse compounds. The evaluation of antioxidant activity of the essential oil measured by delay in sunflower oil oxidation indicated that the antioxidant activity was dependent on the concentration which increased when higher concentrations of the essential oils were applied. The results of DPPH radical assay also indicated that the percentage of inhibition increased with increasing of essential oil concentration and IC50 value for essential oil extracted by MAHD method was obtained 1.25 mg/mL. Therefore the Heracleum persicum essential oil might be recommended for use as a flavoring agent and a source of natural antioxidants in functional foods, formulation of the supplements and in medicinal due to numerous pharmacological activities.
