| Abstract: |
| Aquatic products are the main dietary sources of n-3 long chain polyunsaturated fatty acid（n-3 LCPUFA），such as eicosapentaenoic acid （EPA） and docosahexaenoic acid （DHA）. The consumption amount of aquatic products is low in residents dietary of most inland areas in China，and the intake amounts of EPA and DHA are far lower than the recommendation in these areas. α-linolenic acid （ALA） is the main n-3 PUFA in Chinese dietary pattern and it can be converted to n-3 LCPUFA in vivo. Recent studies indicate that the conversion capacity of ALA is affected by the intake status of ALA and population physiological difference，in which the endogenous conversion capacity is lower in neonates whereas it is higher in women of childbearing age and population with low fish consumption，showing that the dietary ALA is more important to improve fatty acids nutritional status for these population. Related researches were reviewed to get more objective and comprehensive understanding of the effect of ALA on human health. |
