[Reference values of proteins for the Venezuelan population].

This study presents the reference values for protein requirements. The consumption of the Venezuelan population was obtained according to the Food Consumption Monitoring Survey (ESCA) 2010-2012. The diet provided good quality proteins, combining animal and vegetable foods in an approximate ratio of 1:1. The reference values were calculated based on the safe levels of protein intake recommended by WHO/FAO/UN 2007, with an adjustment for protein supply depending on age, weight, and contribution to the caloric formula of proteins for light physical activity. The reference values for protein requirements recommended as safe levels of intake in g/kg/day are 1.14 to 1.80 for males and females less than one-year-old, from 1 to 3 years, 0.90 to 1.14; from 4 to 6 years old, 0.86 to 0.89; and from 7 to 10 years old, 0.91 to 0.92. For adolescents, the average is 0.88 and 1.07 for males and females, respectively. In adults from 20 to 59 years old, 0.83 for men and women is recommended, and for older adults, 1.00 for men and women. In pregnant women, additional consumptions are recommended according to gestation time. Adolescent pregnant women must consume additional 1.2 to 1.7 g/kg/day to normal requirement. In breastfeeding women, the values differ between the first six months postnatal period and after six months of breastfeeding. The reference values for protein in this update were lower than the values of the 2000 version.
