The Claim

Elevated levels of apolipoprotein A and high-density lipoprotein cholesterol, as indicators of cholesterol efflux capacity, mediate a significant portion of the association between ultra-processed food intake and autoimmune-related hypothyroidism, indicating that lipid metabolism dysfunction contributes to the risk of autoimmune thyroid disease.

How it works
1 study reviewed
In plain English

Higher levels of apolipoprotein A and HDL cholesterol, which reflect cholesterol transport efficiency, are linked to part of the connection between consuming ultra-processed foods and developing autoimmune hypothyroidism, suggesting that disruptions in lipid metabolism are involved in the development of autoimmune thyroid disease.

See the scientific wording

Elevated levels of apolipoprotein A and high-density lipoprotein cholesterol, indicators of cholesterol efflux capacity, mediate a significant portion of the association between ultra-processed food intake and autoimmune-related hypothyroidism, suggesting lipid metabolism dysfunction may contribute to autoimmune thyroid disease risk.

Why this might work

Eating a lot of ultra-processed foods changes the fats in the blood, lowering good cholesterol proteins that remove excess cholesterol from immune cells. This causes immune cells to fill up with fat, become inflamed, and wrongly attack the thyroid gland, stopping it from making enough hormones.

  1. Study: Ultra-processed food consumption and incident autoimmune-related hypothyroidism: A sex-stratified prospective analysis from the UK Biobank.

    People who eat a lot of ultra-processed foods have a higher risk of thyroid disease, and this study found that poor cholesterol transport in the blood is one reason why—like a clogged pipe making things back up.
