Abstract
The actual quantity of calcium, phosphorus, magnesium, potassium and sodium in Japanese daily diets, which have been cooked in eight districts in Japan, were determined.
Twenty five samples were gathered, and each sample was consist of 7 to 10 adults's intakes per day.
The average amounts of calcium were 574mg, phosphorus were 934mg, magnesium were 200mg, potassium were 1.95g and sodium were 4.95g per day per adult.
The dietary P to Ca ratio was 1.6.
From these results it may be say that the average mineral intakes per day of adults in Japan are generally adequate.
