Abstract

<p>It is assumed that zinc intake of Japanese have changed as their eating habits have altered after the World War II. However, the actual changes in the zinc intake is not clear because no data was obtained in the National Health and Nutrition Survey in Japan (NHNS) before year 2000. Therefore the weighted average value for zinc was calculated from the result of NHNS 2010 in order to estimate the zinc intake among Japanese. It was found that the total zinc intake increased 2.0 mg from 1946 to 1955, and a change wasn’t seen after that. When looking at the changes by food group, the amount increased remarkably from the animal foods.</p> <p>The result indicated that there was an increase of the zinc intake from meat but its intake from the grains was decreased. It was also found that there was a high percentage of population whose zinc intake was lower than EAR (estimated average of requirement) according to the NHNS Japan in 2015. There is a possibility of inadequate zinc nutritional status in Japanese.</p>
