Milk is a liquid food that possesses an important quantity of highly bioavailable macronutrients. In addition, it is readily accessible, as well as relatively inexpensive. Given that the knowledge of physicians about nutrition and food composition is deficient, in general, many of the dietary interventions recommended in diverse clinical settings lack a scientific basis. The aim of the present review was to produce a technical opinion that serves as a frame of reference to best sustain recommendations for consuming milk and dairy products as daily nutrition in the adult and older adult. The effects of milk and dairy products during the pediatric stage are not addressed in the present work. The Asociación Mexicana de Gastroenterología and the Asociación Mexicana de Gerontología y Geriatría jointly discussed and analyzed topics dealing with the legal designation of milk, the classification and nutritional profile of cow's milk, its nutritional characteristics, its consumption in the adult, intolerance to cow's milk, and associations of milk consumption with digestive tract alterations and other conditions. Finally, certain aspects of milk consumption in the older adult and its relation to overall health are briefly discussed., (Copyright © 2019 Asociación Mexicana de Gastroenterología.

A diagnostic test was applied at the National Autonomous University of Mexico School of Medicine using a two-part format with 42 clinical cases and 210 multiple-choice items. Residents were randomized into two groups: group A (printed test) and group B (computerized test). Academic performance was measured by determination of media, standard deviation, and correct-answer score; the exam was measured by reliability, difficulty index, and discrimination index and question/item assessment were calculated for item analysis. Residents answered a survey questionnaire and time taken to answer was controlled. Results showed that the printed test had higher achievement; there was better reliability for computerized format, and resident opinion was more favorable toward computer use. The two parts of the test were analyzed and results were produced for the first part of the test; in part two, results were very similar. We conclude that lack of experience in computer use could be a determining factor in our results.
