The Claim

Dietary inclusion of 10% ahiflower seed or 10% flaxseed increases egg yolk alpha-linolenic acid (ALA) by more than sixfold compared to control diets, but does not significantly alter the overall n-6:n-3 fatty acid ratio or total polyunsaturated fatty acid content in egg yolks.

Source: Nutritional supplementation of ahiflower seed and press cake in laying hens and its effect on production performance, nutrient digestibility, egg quality, and yolk omega-3 fatty acid enrichment during mid- to post-peak production phase

In plain English

Adding 10% ahiflower seed or flaxseed to chicken feed increases the alpha-linolenic acid content in egg yolks by more than six times compared to standard feed, without changing the ratio of n-6 to n-3 fatty acids or the total amount of polyunsaturated fatty acids in the yolks.

See the scientific wording

Dietary inclusion of 10% ahiflower seed or 10% flaxseed increases egg yolk alpha-linolenic acid (ALA) by more than sixfold compared to control diets, but does not significantly alter the overall n-6:n-3 fatty acid ratio or total polyunsaturated fatty acid content in egg yolks.

Why this might work

When hens eat flaxseed, a specific fat called ALA enters their body, gets sent to the liver, and is converted into other omega-3 fats that are packed into yolk-building molecules and deposited directly into the egg yolk. This process increases ALA in the yolk more than sixfold without changing the total amount of fats or the balance between omega-6 and omega-3 fats.

What the research says

1 study

  1. Study: Nutritional supplementation of ahiflower seed and press cake in laying hens and its effect on production performance, nutrient digestibility, egg quality, and yolk omega-3 fatty acid enrichment during mid- to post-peak production phase

    Adding 10% flaxseed to chicken feed made the egg yolks contain over six times more of a healthy omega-3 fat called ALA, without changing the overall balance of fats — just like the claim says. Ahiflower seed helped other omega-3s but not ALA as much.
