Yes, chicken and eggs are major sources of arachidonic acid in the American diet, with chicken often cited as the top source and eggs as a very significant one.ย Excess arachidonic acid is linked to inflammation through the production of inflammatoryย eicosanoids, which can contribute to chronic diseases and may be associated with premature aging. The body produces all the arachidonic acid it needs, and while it’s essential for functions like wound healing, high dietary intake from sources like eggs can lead to excessive levels.ย
Arachidonic acid and inflammation
- Arachidonic acid (AA) is an omega-6 fatty acid that the body uses to create molecules called eicosanoids.
- Eicosanoids, which includeย prostaglandinsย andย leukotrienes, are crucial for the body’s inflammatory response and are involved in processes like wound healing and immune function.
- However, an excess of arachidonic acid can lead to the overproduction of pro-inflammatory eicosanoids.
- This overproduction is linked to chronic inflammatory conditions such asย rheumatoid arthritisย andย inflammatory bowel disease.ย
Arachidonic acid and aging
- Chronic, low-level inflammation is a known contributor to the aging process and the development of age-related diseases.
- The excessive production of pro-inflammatory eicosanoids due to high AA levels can fuel this chronic inflammation, contributing to the wear and tear on the body associated with premature aging.
- An imbalance, where pro-inflammatory eicosanoids increase while anti-inflammatory ones decrease, is seen in aging and is linked to the aging process.
- Studies have shown that dietary changes, such as those that reduce arachidonic acid intake, may be associated with a lower risk of certain diseases and improved mental health.ย
Dietary sources
- Chicken and eggs are consistently identified as the top sources of arachidonic acid in the American diet.
- Other sources include beef, pork, and certain fish.
- Since the human body can synthesize all the arachidonic acid it needs, excessive dietary intake is not necessary and may be harmful.ย
