Micronutrients & recovery
Dietary iodine intake is primarily derived from dairy products in Canadian adults, and public health policies promoting salt restriction and reduced dairy consumption may inadvertently increase the risk of iodine deficiency.
If you are following a low-sodium diet for blood pressure, be aware that you might be consuming less iodine. Dairy products are a major source of iodine in the Canadian diet. Ensure you are getting enough iodine through other sources like fish, eggs, or supplements if you significantly cut back on dairy and salted foods.
Self-reported intake of dairy products was most strongly associated with iodine status (r = 0.24; p = 2.38 × 10−9) after excluding for iodine supplementation and T4 use... Recent public health policies that advocate for salt restriction and lower dairy intake may inadvertently reduce iodine nutrition of Canadians, and further exacerbate regional variations in iodine deficiency risk.
Why this rating
Large cross-sectional study (n=800) with robust 24h urine analysis, though observational design limits causal inference.
