    In recent years, with the deepening of the concept of health, fish oil has become very popular in the domestic and foreign health care products market, and is even known as "liquid gold"

    Numerous studies have previously shown the health benefits of n-3 PUFAs in fish, including EPA and DHA

    The results showed that people with higher levels of DHA in their blood were 49 percent less likely to develop AD than those with lower levels

    The researchers recruited 3,021 participants from the Framingham progeny cohort and recorded their erythrocyte DHA content (expressed as a percentage of DHA to total fatty acids in erythrocytes) and information about APOE-ε4 genotype

    The fully adjusted model showed that participants with higher levels of DHA in their body (Q5 > 6.

    Since there is a relationship between DHA content in the body and AD risk, is there a similar relationship between EPA and n-3 polyunsaturated fatty acids? The researchers found that increased red blood cell EPA and n-3 polyunsaturated fatty acid levels were not significantly associated with a reduced risk of AD, with only a slight trend

    Previous studies have confirmed that APOE-ε4 is the main genetic risk factor for AD, and carrying an APOE-ε4 allele can increase the risk of AD by 3-4 times

    The researchers then became interested in the interaction between APOE genotype and DHA

    Separate analysis of participants with and without APOE-ε4 revealed that increased DHA levels, which reduced AD risk, were more beneficial in APOE-ε4 carriers

    The study pointed out that only by increasing the DHA content in the diet can effectively delay AD and improve its impact on public health, and the "cost-effectiveness" is very high

    Interestingly, the data for this study were collected from the Framingham progeny cohort

    The study's corresponding author, William S.

    How much should be added? The researchers suggest that dietary DHA intake of about 2 grams per day in high-risk groups may slow the occurrence of AD
