Dietary energy and protein requirements for Saudi Arabia: a methodological approach

Abstract

Based on the available scientific information on human requirements, recommended dietary allowances of energy and protein for different age and sex groups of Saudis were estimated. The per capita requirements of energy and protein [NPU 0.8] at national level were calculated to be 2100 kcal per day and 53 g per day respectively. For men of reference body size 65 kg, the average recommended allowances are 2800 kcal per day and 65 g of protein per day. For women of reference body weight 56 kg, these are 2100 kcal per day and 56 g of protein per day. Additional recommended daily allowances for pregnant and lactating women are given. Protein-energy ratio percentage was calculated as 6%-12%. RDAs and reported energy and protein intakes are compared
