    Se desarroll贸 el programa inform谩tico Interfood v. 1.3 para procesar la informaci贸n alimentaria y generar datos sobre el consumo diet茅tico -en t茅rminos de alimentos, nutrientes y sustancias fitoqu铆micas- v谩lidos para realizar estudios nutricionales y epidemiol贸gicos. 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 fitoqu铆micas); y una base de datos relacional que asocia la informaci贸n del CFCA con la base de datos de alimentos. De esta forma, el programa inform谩tico Interfood calcula la cantidad de cada uno de los alimentos y los nutrientes y las sustancias fitoqu铆micas que una persona consume por d铆a, semana y mes. Interfood es un programa de c贸digo abierto, por lo que sus bases de datos se pueden modificar y actualizar de acuerdo con las necesidades de la investigaci贸n. Este programa ya ha demostrado su utilidad en diversas investigaciones nutricionales y epidemiol贸gicas.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 C贸rdoba, 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, Mar铆a C.
