Abstract
The daily intake of various kinds of lipids by 100 Japanese men (30-59 years of age) was measured directly using the duplicate portion method. The daily intake of total fatty acid (TFA), cholesterol (CHO), plant sterol, and phospholipid (PL) amounted to 44.8g, 295.5mg, 194.1mg, and 2.9g, respectively. The TFA intake of the 30-39-, 40-49- and 50-59-year age groups was 51.8, 41.3, and 45.1g per day, respectively. The saturated fatty acid content differed significantly between the 30-39- and 40-49-year age groups. The mean daily intake of fatty acids derived from marine products was 1.2g per day, and the mean n-6/n-3 ratio was 4.3. The CHO intake of the 30-39-, 40-49- and 50-59-year age groups was 273.8, 274.7, and 331.3mg per day, respectively. A strong correlation was observed only between CHO and PL intake.
