Abstract:
Objective To investigate the dietary nutrition status of plateau frontier forces and to make recommendations on food and nutrients intake for plateau forces.Methods The dietary status of the plateau forces located at an altitude of 4600 m and 4030 m was investigated by weighing method.The dietary ration for soldiers, their daily dietary allowance and dietary balance index were used to evaluate their dietary patterns and nutrient intake.The concentrations of serum vitamin A and 25-OH vitamin D(25-OH VD) were detected by high performance liquid chromatography (HPLC).The arm muscle circumference and body fat rate of soldiers were evaluated by GJB 1636A-2016 and body composition related standard respectively.Results The intake of eggs, milk and plant oil of Unit A was sufficient, while the rest of the food intake did not reach the military standard;The intake of grain and plant oil of Unit B was sufficient,but the rest of the food intake was insufficient.The intake of protein,calcium,phosphonium,sodium,iron,selenium,iodine,copper,manganese,vitamin E and vitamin B3 of Unit A were adequate, but that of energy,potassium,zinc,magnesium,vitamin D,vitamin C,vitamin B1 and vitamin B2 was insufficient, and the intake of vitamin A,vitamin B6,vitamin B9 and vitamin B12 of Unit A was deficient.The intake of energy, protein,vitamin E,vitamin C,vitamin B1 and vitamin B3,and most of the minerals was adequate in Unit B, but vitamin B2 was insufficient.Furthermore, the intake of calcium,iodine,vitamin A,vitamin D and vitamin B was deficient.The proportion of nutrients which supply energy and the energy distribution of three meals in the two units were imperfect.The concentration of plasma vitamin A in both units was sufficient,but the concentration of plasma 25-OH VD was deficient.93.5% soldiers of unit A and 97.7% soldiers of unit B reached the standard of proper muscle circumference,80.6% soldiers of unit A and 70.5% soldiers of unit B had a low body fat rate.Conclusion The dietary structure of plateau border forces is not balanced.The intake of some foods and nutrients is insufficient so that nutritional education is badly needed to improve the dietary status of plateau forces.
