A newly published study conducted in the US investigated the correllation between intake of dairy and dietary Iodine levels. The research showed that higher dairy intakes are linked with improved iodine status.

The study asserts that the use of iodine supplements is low in the U.S. population and the majority of iodine intake comes from food sources, so finding links between diet and iodine levels is very important.

The researchers obtained dietary recall and laboratory data for UIC (urinary iodine concentration) were obtained from those participating in the National Health and Nutrition Examination Surveys (NHANES) 2001-2018 with written permission.

The 26,838 participants were then interviewed regarding their dietary intake in the 24 hrs prior to the interview. Dairy intake (total, milk, cheese, and yogurt) was determined.

The main symptom of iodine deficiency is hypothyroidism. Hypothyroidism occurs when your body’s iodine level decreases and your thyroid gland can’t produce thyroid hormone. This condition is also called underactive thyroid. It causes your metabolism to slow down, leading to fatigue, weight gain and the inability to tolerate cold. Deficiency in iodine in pregnancy can lead to the cognitive impairment of the child.

The research provides evidence to support the importance of ensuring adequate dairy intake. It asserts that it could aid in preventing a potential upcoming public health crisis and serve as helpful tools to tackling existing deficiencies.
