Summary

With this project, the investigators expect to standardize a reliable and optimized methodology based on a 24-hour recall tool assisted by digital photographs with a complete output of foods and nutritional information for the Colombian population.

Detailed description

After recruitment, participants (20) will receive a detailed explanation of the objectives and conditions of the study and will sign the informed consent. Dietary intake assessments will be conducted using 24-hour dietary recalls, assisted with digital photographs registry of the food and beverages consumed, and a brief description (the two 24 dietary recalls will be applied on different and non-consecutive days). Simultaneously, food weighing using a home kitchen scale and drink volume measurements will be used as a reference. For the analysis of nutritional information, the daily food intake extracted from food photologs will be entered into the automated Self-Administered Dietary Assessment Tool (ASA24®). Macro- and micronutrient intake using the actual food weights recorded by the participants, will be estimated from the USDA FNDDS 2017-2018 database, and polyphenols composition from a phenol database. On the day of each 24-h dietary recall, participants will collect a 24-h urine sample to assess their protein, sodium, and potassium intake. Additionally, the day after each 24 dietary recall, participants will also provide blood samples to determine circulating levels of vitamin C, vitamin B1, vitamin K1, folate, zinc, copper, and beta-carotene; and fecal samples to identify vegetable species in feces.
