Iodine Content in Redmond Real Salt
Redmond Real Salt is a natural sea salt mined from an ancient seabed in Utah. Unlike common table salt that often has minerals removed and iodine added, Redmond Real Salt retains over 60 trace minerals, including some naturally occurring iodine. However, the amount of iodine is relatively small. The crucial question is whether this amount is adequate for daily needs.
Iodine Levels: Not Enough for Daily Needs
Redmond Real Salt, while containing naturally occurring iodine, does not provide enough to meet the recommended daily allowance (RDA) through its use alone. A typical 1/4 teaspoon serving provides approximately 18-23 mcg of iodine.
Adults need 150 mcg of iodine daily. A single serving of Redmond salt provides only about 10-15% of the daily requirement.
Redmond Salt vs. Iodized Table Salt: A Comparison
Comparing Redmond Real Salt and iodized table salt clarifies the difference in iodine content and processing.
| Feature | Redmond Real Salt (Unrefined) | Iodized Table Salt (Refined) |
|---|---|---|
| Iodine Source | Naturally occurring trace mineral | Artificially added potassium iodide |
| Iodine per 1/4 tsp | ~18-23 mcg | ~78 mcg |
| % of Adult RDA | ~10-15% | ~52% |
| Processing | Unrefined, nothing added/removed | Heavily processed, bleached, anti-caking agents added |
| Bioavailability | Highly bioavailable | Lower bioavailability (~10%) |
Iodized table salt has significantly more iodine per serving due to artificial fortification. Salt iodization began in the 1920s to combat iodine deficiency disorders. While most people consume adequate iodine, relying solely on Redmond salt without other sources may lead to deficiency.
Meeting Your Daily Iodine Requirements
Since Redmond salt alone is insufficient, including other iodine-rich foods in your diet is vital.
Rich Food Sources of Iodine
- Seafood: Fish like cod, tuna, and shrimp are good sources. Seaweed (kelp, nori) is especially rich in iodine.
- Dairy Products: Milk, yogurt, and cheese provide iodine.
- Eggs: Eggs are a source of iodine.
- Fortified Grains: Some breads and cereals use iodate dough conditioners, contributing to intake.
Conclusion
Does Redmond salt have enough iodine? It contains natural traces, but not enough to serve as the primary source for the recommended daily amount. It is valued for its purity and taste, not as a primary iodine supplement.
To ensure adequate iodine intake, incorporate iodine-rich foods into your diet. Consult a healthcare professional for dietary concerns.
