The Claim

Higher intake of ultra-processed foods is associated with an increased risk of autoimmune-related hypothyroidism in both men and women, with hazard ratios of 1.36 for men and 1.28 for women in the highest intake group.

In plain English

People who eat more ultra-processed foods have a higher rate of autoimmune-related hypothyroidism compared to those who eat less, and this pattern is seen in both men and women.

See the scientific wording

The association between ultra-processed food intake and autoimmune-related hypothyroidism is consistent across both men and women, with hazard ratios of 1.36 for men and 1.28 for women in the highest intake group, indicating that this dietary risk factor affects both sexes despite the higher overall prevalence in women.

Why this might work

Eating a lot of ultra-processed foods increases harmful substances like sugar, salt, and bad fats in the body. This damages the kidneys and disrupts cholesterol transport, causing toxins and fats to build up in the blood. These changes activate immune cells that mistake the thyroid gland for a threat, leading to its destruction and reduced hormone production.

  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, like chips and sugary snacks, are more likely to develop an autoimmune thyroid problem, no matter if they’re male or female—even though women get it more often overall. This study found that risk goes up for both sexes.
