In the pursuit of a healthy diet, many individuals have become cautious about their sodium intake to avoid the risks of high blood pressure, heart disease, and stroke. However, according to experts, one essential nutrient often overlooked in this process is iodine. As the primary source of iodine in most diets is table salt, Consumer Reports emphasizes the important role this mineral plays in maintaining thyroid health and provides practical tips to ensure adequate intake.
Iodine is crucial for the production of thyroid hormone, which regulates weight, cognitive function, energy levels, and even the growth of hair and nails, according to Marilyn Tan, a clinical associate professor of medicine at Stanford University School of Medicine. Inadequate iodine levels can lead to hypothyroidism, characterized by symptoms such as weight gain, fatigue, memory issues, and intolerance to cold. Hypothyroidism is increasingly prevalent in older individuals but often goes undiagnosed due to its symptoms being erroneously attributed to the aging process.
While iodine deficiency is less common today, certain populations, including older adults, may still be at risk. A study involving 189 women aged 51 to 86 found that 60 percent displayed moderate iodine deficiency. Therefore, it is essential to understand the available sources of iodine and how to incorporate them into one’s diet.
Iodine occurs naturally in a limited number of foods, including fruits, vegetables, seaweed, seafood, dairy products, and eggs. However, changes in farming practices, food processing methods, and the environment have led to inconsistencies in the iodine content of these foods. Consequently, relying solely on natural sources may not guarantee sufficient iodine intake.
Adrienne Hatch-McChesney, a research dietitian in the Army’s Military Nutrition Division, explains that processed and packaged foods are typically not made with iodized salt. Additionally, popular alternatives such as sea, Himalayan, or kosher salts do not provide sufficient iodine. Moreover, the iodine content of foods is often not listed on nutrition facts labels, making it challenging for individuals to track their iodine intake accurately.
To ensure an adequate iodine intake, Consumer Reports recommends using iodized salt when adding salt to food or cooking. While it is important to be mindful of sodium consumption, it is still worth using a sprinkle of iodized salt for its iodine content. Supplementing the diet with iodine-rich foods is also beneficial. The recommended daily allowance of iodine is 150 micrograms (mcg), which can be obtained from sources such as whole-wheat bread made with iodate dough conditioner, baked cod, dried seaweed, oysters, plain nonfat Greek yogurt, nonfat milk, and eggs.
Consumer Reports recommends consulting a healthcare professional for personalized advice on iodine intake, especially for individuals with specific dietary restrictions or medical conditions.
As the understanding of iodine’s vital role in maintaining thyroid health continues to evolve, it becomes increasingly important to raise awareness about the potential risks of inadequate iodine intake. By incorporating iodine-rich foods into their diets, individuals can proactively support their thyroid function and overall well-being.
