Understanding the Difference: Real Salt and Iodine
When exploring the mineral content of different salts, it is vital to distinguish between a naturally occurring element and a fortified additive. The term "Real Salt" is often used to describe unrefined mineral-rich salts, such as the popular brand Redmond Real Salt, which is mined from an ancient sea bed in Utah. Unlike modern sea salt, which can be exposed to contemporary pollutants, this ancient source is protected and remains unprocessed. The key difference when it comes to iodide is that Real Salt contains only the small, natural amount of iodine that was present in the ancient sea bed, without any artificial fortification.
For decades, iodized table salt has been a public health measure to combat widespread iodine deficiency, especially in inland areas where the soil has a low iodine content. This was necessary because the trace amount of natural iodine in salt is often not enough to meet daily nutritional requirements. While conventional table salt is heavily processed and stripped of its natural minerals before the iodine is added, Real Salt is left in its whole, unprocessed state.
The Natural Iodine Content in Real Salt
So, does real salt have iodide? The answer is yes, but only in its natural, unfortified form. The amount is significantly lower than that found in table salt that has been purposefully iodized. For instance, a 1/4 teaspoon of Redmond Real Salt provides about 23 micrograms of naturally occurring iodine, which is approximately 10% of the recommended daily allowance (RDA) for adults. This small amount is a result of the salt's natural mineral composition, which includes over 60 different trace minerals. While a small, natural contribution is beneficial, it is not considered a reliable source for meeting your full daily iodine needs, especially for those at risk of deficiency, such as pregnant women or individuals with restricted diets.
Real Salt vs. Iodized Table Salt: A Comparison
To highlight the key differences, consider this comparison table. It details how the two types of salt vary in their processing, mineral and iodine content, and primary purpose.
| Feature | Real Salt (Unrefined) | Iodized Table Salt |
|---|---|---|
| Processing | Minimally processed; unrefined, retains natural minerals. | Heavily processed; refined, stripped of most minerals. |
| Iodine Source | Trace amounts occur naturally within the ancient sea salt deposit. | Artificially fortified with iodide (e.g., potassium iodide). |
| Iodine Content | Contains a small, natural amount, typically insufficient to meet RDA. | Fortified to provide a consistent, significant amount, enough for RDA. |
| Mineral Profile | Contains a full spectrum of over 60+ trace minerals. | Primarily sodium chloride, with anti-caking agents and dextrose. |
| Purpose | Used for flavor and natural mineral intake. | Used to prevent widespread iodine deficiency as a public health measure. |
Alternative Dietary Sources of Iodine
For those who prefer to use unrefined salts like Real Salt, it is crucial to obtain sufficient iodine from other dietary sources. The body cannot produce iodine, so it must be acquired from the diet. Incorporating these foods into your meals can help ensure you meet your daily requirements:
- Seafood: Fish (like cod and tuna), shellfish (like shrimp and oysters), and especially seaweed (kelp, nori, and wakame) are some of the richest sources of iodine.
- Dairy Products: Milk, yogurt, and cheese can contain significant amounts of iodine, which comes from supplements in the cattle feed and iodine-based sanitizers used during the milking process.
- Eggs: A large egg provides a good source of iodine and is an easy way to boost your daily intake.
- Fortified Foods: In some regions, bread and cereal products may be fortified with iodine.
- Supplements: For those with dietary restrictions or diagnosed deficiencies, a healthcare provider might recommend an iodine supplement.
Conclusion
In summary, the answer to "does real salt have iodide" is that it contains a small, naturally occurring amount of iodine, not added iodide. While this contributes a minor amount of the essential mineral, it should not be relied upon as a primary source for meeting your daily intake requirements. Unrefined salts, like Real Salt, offer a full spectrum of trace minerals without additives, but if you choose them over iodized salt, you must make a conscious effort to obtain iodine from other food sources. For most individuals, especially those living far from the coast or with restrictive diets, relying on a variety of iodine-rich foods is the most prudent strategy. As always, for personalized advice on your nutritional needs, consulting with a healthcare professional is recommended.

Frequently Asked Questions
Q: Is Real Salt the same as iodized salt? A: No, Real Salt is unrefined and contains only naturally occurring trace iodine. Iodized salt is table salt that has been fortified with added iodine.
Q: How much iodine is in Real Salt? A: A 1/4 teaspoon of Redmond Real Salt contains about 23 micrograms of naturally occurring iodine, which is a small fraction of the daily recommended intake.
Q: Can I get enough iodine from Real Salt alone? A: No, the amount of natural iodine in Real Salt is not sufficient to meet the full daily recommended allowance. You should seek other dietary sources.
Q: What are the best food sources of iodine besides salt? A: Some of the best natural sources include seafood (like cod, shrimp, and seaweed), dairy products, and eggs.
Q: Why was iodine originally added to table salt? A: Iodine was added as a public health measure to prevent widespread iodine deficiency, which can cause thyroid problems like goiter.
Q: Is one type of salt healthier than the other? A: Neither is inherently healthier; they serve different purposes. The best choice depends on your overall diet and how you meet your iodine needs.
Q: What are the symptoms of an iodine deficiency? A: Symptoms can include an enlarged thyroid gland (goiter), fatigue, weight gain, and impaired cognitive function.
Q: Does Real Salt have anti-caking agents? A: No, Real Salt is unrefined and contains no anti-caking agents, unlike many commercial table salts.
Q: Should pregnant women use iodized salt? A: Pregnant and breastfeeding women have increased iodine needs and should consult a healthcare provider. While iodized salt can contribute, they may need additional sources like a prenatal vitamin.
