对福建省原发性肝癌（ＰＨＣ）死亡率最高的同安县及最低的松溪县采用称量法对居民黄曲霉毒素Ｂ１（ＡＦＢ１）摄入量及膳食营养状况进行调查采样分析。结果显示：同安居民ＡＦＢ１摄入量达２１３６．３ｎｇ／日，为松溪居民ＡＦＢ１摄入量（２１４．４ｎｇ／日）的９．９６倍。两地区居民膳食热能和蛋白质数量基本满足需要，但优质蛋白质只占ＲＤＡ的１７％。同安居民钙、硒摄入均不足或严重不足，分别占ＲＤＡ的４６．８１％和７２．３４％，略高于松溪（４０．９３％和６５．７４％）。同安居民视黄醇当量、核黄素的摄入量分别为ＲＤＡ的２３．１３％和５９．１７％，低于松溪（５０．８５％和７１．６７％）。同安居民膳食脂肪摄入量低于松溪（分别为３４．６１ｇ和６２．１２ｇ），但不饱和脂肪酸尤其多不饱和脂肪酸所占比例远高于松溪，饱和∶单不饱和∶多不饱和脂肪酸分别为１∶１．７４∶１．８７和１∶１．３９∶０．５６。
Tongan County, which has the highest mortality rate of primary liver cancer (PHC) in Fujian Province, and Songxi County, the lowest in China, used a weighing method to investigate the sampling and analysis of aflatoxin B1 (AFB1) intake and dietary nutrition status of residents. The results showed that the intake of AFB1 in Tongan residents was 2136.3 ng/day, which was 9.96 times the AFB1 intake (214.4 ng/day) of Songxi residents. The dietary heat and protein levels of the residents in both regions basically meet the needs, but the quality protein only accounts for 17% of RDA. The intake of calcium and selenium in Tongan residents was insufficient or severely inadequate, accounting for 46.81% and 72.34% of RDA, respectively, slightly higher than that of Songxi (40.93% and 65.74%). The retinol equivalent and riboflavin intake of Tongan residents were 23.13% and 59.17% of RDA, respectively, lower than Songxi (50.85% and 71.67%). Tong’an residents’ dietary fat intake was lower than Songxi (34.61g and 62.12g, respectively), but the proportion of unsaturated fatty acids, especially polyunsaturated fatty acids, was much higher than that of Songxi. Saturated: monounsaturated: polyunsaturated The fatty acids were 1:1.74:1.87 and 1:1.39:0.56, respectively.
