Pregnant women should avoid consuming excessive amounts of Arachidonic Acid (ARA)?
Hello, Nutritionist: I am currently over two months pregnant.
From various sources, I have learned that consuming products rich in DHA and ARA during pregnancy can be beneficial for fetal brain development.
Therefore, I recently went to the pharmacy to purchase prenatal formula containing DHA and ARA.
However, the pharmacist advised me against consuming too much ARA and suggested that I should not buy formula with added ARA.
Is this true? Why is that? What is the daily limit? I hope to receive this information soon.
Thank you!

Hello: I believe the ARA you are referring to is Arachidonic acid, which can be synthesized from the alpha-linolenic acid we consume.
Alpha-linolenic acid is found in plant oils.
Whether it is EPA, DHA, or Arachidonic acid, alpha-linolenic acid, etc., they all belong to the category of fatty acids.
Currently, the recommendation for total fat intake is 25-30% of total daily calories, with the ideal ratio of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids being 1:1:1 (the aforementioned fatty acids are polyunsaturated).
Therefore, there is no specific recommended intake for Arachidonic acid alone.
As mentioned, Arachidonic acid can be synthesized from alpha-linolenic acid, so there is no need for special supplementation to avoid excessive fat intake.
You can check the detailed nutritional recommendations for pregnant women at the Department of Health's Food and Drug Administration or the Taiwan e-Hospital website.
The key point remains to maintain a balanced diet.
Regular infant formula (low-fat options can be chosen, and if weight gain is excessive, skim milk powder can be selected) is sufficient.
Sincerely, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info
During pregnancy, the nutritional needs of a woman change significantly, particularly concerning essential fatty acids like DHA (Docosahexaenoic Acid) and ARA (Arachidonic Acid). Both of these fatty acids play crucial roles in fetal development, especially in brain and eye development. However, there are important considerations regarding their intake, particularly ARA.
Understanding DHA and ARA
DHA is an omega-3 fatty acid primarily found in fish and algae, and it is vital for the development of the fetal brain and retina. ARA, on the other hand, is an omega-6 fatty acid that is also important for brain development and is found in animal products and certain oils. While both DHA and ARA are important, the balance and source of these fatty acids are crucial.
Concerns About ARA Intake
The concern regarding excessive ARA intake during pregnancy stems from its role in inflammatory processes and its potential to influence the balance of omega-3 and omega-6 fatty acids in the body. ARA is synthesized in the body from linoleic acid, which is abundant in many dietary sources. Therefore, most pregnant women can obtain sufficient ARA through a balanced diet without the need for additional supplementation.
Excessive intake of ARA could potentially lead to an imbalance in fatty acid ratios, which may have implications for inflammation and overall health. This is why some healthcare professionals recommend caution with ARA supplementation, especially in the form of fortified products like certain prenatal formulas.
Recommended Intake
Currently, there are no specific established daily limits for ARA intake during pregnancy. However, it is generally advised that pregnant women focus on a balanced diet that includes a variety of sources of both omega-3 and omega-6 fatty acids. The American Pregnancy Association suggests that pregnant women should aim for about 200-300 mg of DHA per day, but there is no specific recommendation for ARA since it can be synthesized from dietary sources.
Dietary Sources
To ensure adequate intake of both DHA and ARA, pregnant women should consider the following dietary sources:
- DHA: Fatty fish (like salmon, sardines, and mackerel), fish oil supplements, and algae-based supplements.
- ARA: Eggs, meat, poultry, and dairy products.
Conclusion
In summary, while DHA is crucial for fetal brain development, ARA should be consumed in moderation. Pregnant women are generally advised to obtain these fatty acids from a balanced diet rather than relying on supplements, especially for ARA. If you are considering prenatal supplements or fortified products, it is essential to consult with a healthcare provider to ensure they meet your nutritional needs without exceeding safe limits. Always prioritize whole food sources and maintain a balanced intake of essential fatty acids for optimal health during pregnancy.
