“…This exclusion criterion was set because it has been shown that elderly men with higher ARA levels might be difficult to show a response to ARA supplementation on the P300 evaluation 26 . However, ARA content of participants in the present study was 8.7 and was in the normal range of Japanese elderly 6.4 41 44 in serum/plasma phospholipids . These data suggest that the participants in the present study were not selected from a limited and special population but represent a general population of Japanese elderly men.…”

“…It is, however, lower than ®gures observed in Japan (Yamori et al, 1985;Takahashi et al, 1991). Likewise, the Norwegian consumption of ®sh and ®sh products is considerably higher than in most Western populations (Houwelingen van et al, 1989;Holst, 1991), but not as high as in Japan (Tominaga & Kato 1992;Iso et al, 1989).…”

Objective: To examine the relation between consumption of ®sh and ®sh products registered by a comprehensive food frequency questionnaire and the composition of fatty acids in serum phospholipids. Design: Cross-section study. Setting: Cardiovascular screening centre in Trondheim, Mid-Norway. Subjects: Of 256 eligible women 242 agreed to participate in the present study. Altogether 234 middle-aged women (91.4%) completed the questionnaire and gave a valid blood sample. Results: Total frequency consumption of ®sh for dinner showed only weak association with serum phospholipid fatty acid composition. In separate analyses of lean and fatty ®sh, consumption of fatty ®sh was negatively associated with n-6 and positively associated with n-3 fatty acids in serum phospholipids, while no signi®cant associations were found for lean ®sh consumption. Cod liver oil consumption was strongly related to the phospholipid fatty acid composition. The associations improved moderately when adding portion size information. Spearman's correlation coef®cient between dietary intake of eicosapentaenoic acid (EPA) and serum phospholipid EPA was 0.58, and Spearman's correlation coef®cient between intake of docosahexaenoic acid (DHA) and serum phospholipid DHA was 0.53. Conclusions: This study suggests that in populations with a high consumption of ®sh and cod liver oil, habitual intake can be re¯ected in serum phospholipids. However, as the fat content of ®sh is highly variable, separate registration of lean and fatty ®sh consumption is needed.

Descriptors: ®sh; cod liver oil; n-3 fatty acids; food frequency questionnaire; serum phospholipid fatty acids.

“…In addition to inaccurate answers in the questionnaire, the difference in bioavailability of fatty acids in children and adults may attenuate the correlations. Among adults over the age of 30 y, older people have more serum EPA, DPA, and DHA (10,47,48); fatty acid content of RBCs may be lower in children than in adults. Furthermore, because RBC fatty acids could indicate a steady-state equilibrium or a transient state with new fatty acids to be delivered to a body compartment (49), RBC n-3 PUFAs, precursors of physiologically active substances, may not reflect dietary intake in children during maturation and weight gain (18).…”

SummaryWe investigated the association between nutrient biomarkers and dietary intake estimated using a brief self-administered dietary history questionnaire (BDHQ) for Japanese children and adolescents. Blood samples were collected from 398 subjects (5th graders of elementary school aged 10-11 y, and 2nd graders of secondary schools aged 13-14 y) randomly selected from among students in Shunan City, Japan, who were then required to answer two questionnaires. Spearman correlations were calculated between dietary intake and the corresponding biomarkers (serum carotenoids, tocopherols, and erythrocyte fatty acids). Correlations with ␤ -carotene and ␤ -cryptoxanthin were significant in the 13-and 14-y age group ( r ϭ 0.220-0.333, p Ͻ 0.030) and the 10-and 11-y age subgroup who answered the questionnaire with assistance ( r ϭ 0.295-0.299, respectively, p ϭ 0.006). Consumption of green-yellow vegetables and fruits was significantly correlated with ␤ -carotene and ␤ -cryptoxanthin levels ( r ϭ 0.205-0.341, p Ͻ 0.047). In the 13-and 14-y age group, correlations with eicosapentaenoic and docosahexaenoic acids were between 0.215 and 0.473 ( p Ͻ 0.040). Total seafood intake was significantly correlated with marine n -3 polyunsaturated fatty acids (PUFAs; r ϭ 0.239-0.420, p Ͻ 0.023). In the 10-and 11-y age subgroup who completed the questionnaire with assistance, seafood intake was significantly correlated with marine n -3 PUFAs ( r ϭ 0.239-0.243, p Ͻ 0.032). In conclusion, dietary intake assessed using the BDHQ reflects the corresponding biomarkers for 13-and 14-y-olds; however, when used for elementary school children, caution is necessary in interpreting the results.
