An average large egg contains about 16% of the daily value for iodine, but the specific amount can vary greatly. So, do free range eggs have iodine, and is their level significantly different from conventional eggs? The answer is nuanced, depending heavily on the hen's diet and environment.

Iodine is a vital mineral required for proper thyroid function, yet many common spices contain very little of it. The primary seasoning that provides a reliable source is iodized table salt, while a select few others, like kelp powder, offer concentrated amounts, making it important to know where to look.

According to the USDA/FDA, 3 tablespoons of dry-roasted, salted peanuts contain only 0.1 mcg of iodine, which is a very small amount. This means that while they aren't completely devoid of the mineral, peanuts are not a reliable source of iodine for meeting your daily nutritional needs.

According to a 2010 study presented by the American Association of Clinical Endocrinologists, the iodine content in most fast food items, with a few notable exceptions, is insufficient for meeting daily nutritional requirements. While many processed foods are notoriously high in sodium, they often rely on non-iodized salt, making them a poor source of this essential mineral.

While most people associate iodine primarily with seafood, certain fruits do contain this essential mineral, though generally in smaller quantities. Strawberries are one of the most notable fruit sources, providing approximately 13 mcg of iodine per 100 grams. Including a variety of these foods in your diet is key to supporting optimal thyroid function and overall well-being.

A 2020 study showed that while some vegetables can be biofortified with iodine, a potato plant is not the most suitable candidate for this process. Despite this, potatoes are often cited as a good source of the essential mineral iodine, which can lead to confusion. The reality is that the iodine content in a potato is highly variable and often lower than many other dietary sources.

According to reputable sources like the Mayo Clinic, taking Lugol's iodine on an empty stomach can increase the risk of gastrointestinal side effects, including upset stomach, nausea, and vomiting. For this reason, it is generally advised to consume it with food or after a meal to reduce these potential issues.

According to the World Health Organization, the mean global intake of salt is more than double the recommended amount. For most adults, achieving the daily iodine requirement for proper thyroid function can be done with a balanced diet that includes iodized salt, without exceeding general salt intake guidelines.

The iodine content of ice cream is surprisingly variable, with one study showing a range from 18 to 359 micrograms per 100 grams, making it an unpredictable source of this essential mineral. The question of **how much iodine does ice cream have?** is more complex than it appears, depending on multiple factors in its production.

While seaweed is one of the richest natural sources of iodine, the question remains whether common root vegetables like sweet potatoes are a significant contributor to daily intake. The iodine content in sweet potatoes varies widely based on factors like soil composition, making a definitive high-or-low answer complex, especially for a balanced nutrition diet.
