We estimated the per capita daily intake of condensed phosphates (CP) consisting of pyrophosphates, polyphosphates and metaphosphates with market basket system. About 340 articles of processed food were classified into following seven groups i.e. (1) Seasonings and beverages, (2) cereals, (3) potatoes, pulses, nuts and seeds, (4) fishes, shellfishes and meats, (5) fats, oils and dairy products, (6) sugars and confectioneries and (7) fruits, vegetables and algae. CP in each group were determined. Intake of CP was estimated from the concentration of CP and the amount of food in each group. (1) Daily intake of CP was 15.8mg, and that of pyrophosphates, polyphosphates and metaphosphates were 7.1mg, 3.8mg and 5.0mg respectively. (2) Most of intake came from No. 5 (6.0mg) and No. 4 (5.1mg) group. Main sources were cheese in No. 5 group and processed fish and meats in No. 4 group. The kind and amount of cheese affected intake of CP. (3) In comparison of the east, middle and west area in Japan, intake in the east and west areas were somewhat larger than in the middle area. Intake from No. 5 group in the east area was two times larger than others. For this reason it is supposed that cheese in the east area contained large amount of CP. (4) Intake of CP tends to increase, according to the survey in 1983, 1987, 1991 and 1994. (5) Intakes in the aged and schoolchild were larger than adult. Intake from No. 4 group in each generation was similar but intake from No. 5 was variable depending on the kind of cheese. Intakes from No. 6 and No. 7 in schoolchild were more than in other generation.
