Shrimp is considered to have scientific justification for supporting thyroid gland function, primarily due to its high iodine content. Iodine is an essential micronutrient required for the synthesis of thyroid hormones (thyroxine T4 and triiodothyronine T3), which are critical regulators of metabolism and overall thyroid health. Shrimp, along with other seafood, is recognized as a good dietary source of iodine, with typical concentrations ranging from 20 to 40 micrograms per 100 grams, although this can vary depending on the shrimp’s habitat and diet. The U.S. National Institutes of Health (NIH) and other authoritative nutrition sources list shrimp among foods that can help prevent iodine deficiency, which is a well-established cause of hypothyroidism and goiter. While there are no direct clinical trials specifically examining shrimp consumption and thyroid health outcomes, the broader scientific understanding of dietary iodine’s importance for thyroid function provides the rationale for recommending iodine-rich foods, including shrimp, as part of a thyroid-supportive diet. It is worth noting that for individuals with normal iodine intake, excess consumption of iodine-rich foods may not confer additional benefit and, in rare cases, could even be detrimental. In summary, shrimp’s role in thyroid support is scientifically valid due to its iodine content and the critical role of iodine in thyroid hormone production.
