Desarrollo de un programa informático para estudios nutricionales Development of a software program for nutrition studies

Se desarrolló el programa informático Interfood v. 1.3 para procesar la información alimentaria y generar datos sobre el consumo dietético -en términos de alimentos, nutrientes y sustancias fitoquímicas- válidos para realizar estudios nutricionales y epidemiológicos. El programa se basa en tres componentes fundamentales: el cuestionario de frecuencia de consumo alimentario (CFCA); una base de datos de alimentos frecuentes y su contenido en 131 compuestos (macro y micronutrientes y sustancias fitoquímicas); y una base de datos relacional que asocia la información del CFCA con la base de datos de alimentos. De esta forma, el programa informático Interfood calcula la cantidad de cada uno de los alimentos y los nutrientes y las sustancias fitoquímicas que una persona consume por día, semana y mes. Interfood es un programa de código abierto, por lo que sus bases de datos se pueden modificar y actualizar de acuerdo con las necesidades de la investigación. Este programa ya ha demostrado su utilidad en diversas investigaciones nutricionales y epidemiológicas.The Interfood v. 1.3 software program was developed to process nutrition information and generate data on dietary intakes-in terms of food, nutrients, and phytochemical substances-valid for conducting studies on nutrition and epidemiology. The program has three basic components: the dietary intake frequency questionnaire CFCA); a database of common foods and their composition of 131 possible substances (macro- and micronutrients and phytochemicals); and a relational database that links the CFCA data with the food database. In this manner, the Interfood software program calculates the amount of food, nutrients, and phytochemical substances consumed by an individual daily, weekly, and monthly. Interfood is an open-source program; as such, the database can be modified and updated according to study requirements. This program has already proven useful to various studies of nutrition and epidemiology

Beef consumption and fatty acids serum concentration: relationship with salivary gland tumors in Córdoba, Argentina

The objective of the present study was to analyze beef consumption, conjugated linoleic acid (CLA) and n-3 fatty acid (FA) serum concentration and their relation to salivary gland tumors (SGT). A questionnaire on non-nutritional risk factors and a validated food frequency questionnaire were applied in 20 SGT and 20 control (Co) patients. Materials and Methods: Food data were processed by the Interfood v.1.3 software. Serum CLA was analyzed by chromatography. Results: Non-significant differences were found between SGT and Co regarding lean and fatty BC and serum CLA. Serum n-3 linolenic acid concentration was higher in Co than in SGT (p=0.004). No associations between BC and CLA serum concentration were found, but a strong-positive association between total energy intake and total fat intake and SGT were observed. A significant inverse association between oleic and linoleic FA intake and SGT was recorded. Conclusion: Serum oleic and linolenic FAs showed a significant negative association with SGT.http://ar.iiarjournals.org/content/34/10/5579.long#sec-3publishedVersionFil: Cittadini, María C.
