How to make water with iron fish? A Complete Guide to Boosting Your Iron Intake

5 min read

According to the World Health Organization, iron deficiency is the most common nutritional disorder globally, impacting over 2 billion people. Fortunately, a simple tool known as the 'iron fish' can be used to naturally fortify water and food with absorbable iron, offering an accessible and effective solution to this widespread problem.

Quick Summary

Using an iron ingot shaped like a fish is a practical and reusable method to infuse liquids with iron during cooking. The process involves boiling the iron fish with water and a small amount of acid, a simple technique for boosting dietary iron without altering the taste.

Key Points

  • Boil with Acid: For optimal iron release, always add 2-3 drops of citrus juice or vinegar to the water when boiling the iron fish.

  • Clean Immediately: To prevent rust, wash and thoroughly dry the iron fish with a towel immediately after each use.

  • Safe for Most: The iron fish is a safe, family-friendly method for boosting iron intake, including for pregnant women and vegans.

  • Consistent Release: When used correctly, the iron fish releases a reliable amount of absorbable iron into liquids.

  • Not a Cure-All: The iron fish supplements your diet but does not replace medical treatment for diagnosed conditions like severe anemia or underlying health issues.

  • Check for Hemochromatosis: Individuals with genetic iron overload disorders like Hemochromatosis should not use iron fish.

What is an Iron Fish and How Does it Work?

An iron fish, often referred to as a Lucky Iron Fish, is a small, reusable cooking tool made from food-grade electrolytic iron. Inspired by the tradition of cooking with cast-iron pots, the tool is designed to safely and consistently release absorbable iron particles into liquids and foods during boiling. This provides a sustainable and side-effect-free way to supplement your dietary iron intake, especially for individuals at high risk for deficiency, such as pregnant women, children, and those on vegetarian diets. The iron released from the fish is easily absorbed by the body, helping to restore iron stores over time.

The Science Behind the Iron Fish

The key to the iron fish's effectiveness lies in a chemical reaction that occurs during boiling. When the iron fish is added to a liquid, particularly one that is slightly acidic, the low pH helps to leach tiny iron particles from the surface of the ingot. This releases a dose of 6-8 mg of iron per liter of liquid, which is then absorbed into the bloodstream when consumed. The addition of a citrus wedge, a few drops of vinegar, or other acidic ingredients is crucial for maximizing iron release, making it a reliable method for iron fortification. Clinical trials have shown that regular use can significantly improve iron status and reduce the prevalence of anemia.

Step-by-Step Guide: How to Make Water with an Iron Fish

Making iron-fortified water is a straightforward process that takes just a few minutes. This nutrient-dense water can be used as a base for soups, stews, rice, oatmeal, or consumed directly.

To make iron water, you will need:

  • An iron fish (e.g., Lucky Iron Fish)
  • 1 liter (4 cups) of water
  • 2-3 drops of citrus juice (lemon or lime) or a small piece of fruit
  • A pot or kettle for boiling
  • A scrubby sponge and dish soap for cleaning

Instructions:

  1. Wash the Fish: Before each use, wash the iron fish thoroughly with soap and water, and rinse it clean.
  2. Boil the Water: Bring 1 liter (4 cups) of water to a rolling boil in a clean pot.
  3. Add Acid and Iron Fish: Add 2-3 drops of citrus juice or a small wedge of lemon to the boiling water. This slight acidity is key to activating the iron release. Then, carefully place the clean iron fish into the pot.
  4. Simmer: Let the water and iron fish simmer for at least 10 minutes. This allows sufficient time for the iron particles to be released.
  5. Remove the Fish: Carefully remove the iron fish from the pot using a utensil. The water is now fortified and ready to use.
  6. Use or Store the Water: Drink the fortified water on its own, or use it as a cooking liquid. Leftover water can be stored in the refrigerator.
  7. Clean the Fish Immediately: After removing the iron fish, wash it immediately with soap and water. Dry it completely with a towel to prevent rust, and store it in a dry place.

Cleaning and Caring for Your Iron Fish

Proper care is essential for extending the life of your iron fish and ensuring it remains effective. Neglecting cleaning and drying can lead to rust formation, which is preventable with simple steps.

  • Wash after every use: Always wash the iron fish with dish soap and water immediately after use. Scrub off any residue, as letting food particles sit on the surface can encourage rust.
  • Dry thoroughly: This is the most important step to prevent rust. Use a kitchen towel to dry the fish completely. Never let it air dry or sit wet.
  • Use oil for protection: Applying a drop or two of food-grade oil, like Lucky Iron Protection Oil, after drying can create a barrier against moisture.
  • Remove rust if it occurs: If rust appears, don't worry—it's fixable. Add a few drops of lemon juice and scrub the rust off with a scrubby sponge. Wash again with soap and water, and dry thoroughly.

Iron Fish vs. Cast Iron Pans

While both an iron fish and a cast iron pan can increase the iron content of food, there are notable differences in their usage and results.

Feature Iron Fish Cast Iron Pan
Portability Small and lightweight; ideal for travel. Heavy and bulky; limited to home kitchen use.
Consistency Designed to release a consistent 6-8mg of iron per liter. Iron release varies significantly based on pan seasoning and wear.
Ease of Use Simply add to boiling liquid for 10 minutes. Requires seasoning, can be heavy to handle.
Application Best for liquids (water, soups, curries, rice). Versatile for frying, searing, and baking.
Maintenance Minimal maintenance; requires immediate drying to prevent rust. Requires specific seasoning and care to maintain surface.
Flavor Impact No change in taste when used correctly. Can impart a metallic taste if not well-seasoned or if overused.

Safety and Considerations for Using an Iron Fish

For most people, the iron fish is a safe and effective way to supplement iron intake. It's safe for use by the entire family, including pregnant and nursing women. However, it is always recommended to consult a healthcare provider before starting any new supplementation method, especially if you are concerned about your iron levels. People with specific medical conditions, like Hemochromatosis, a genetic disorder causing excessive iron accumulation, should not use an iron fish. The manufacturer, Lucky Iron Life, emphasizes that their products are thoroughly tested for safety and do not contain harmful contaminants.

Conclusion: A Simple Solution for Better Iron Intake

Using an iron fish to make iron-fortified water is a remarkably simple yet powerful method for addressing dietary iron deficiency. By following the easy steps of boiling the fish with water and a bit of acid, you can consistently increase your iron intake without relying on expensive supplements or changing your diet drastically. For those seeking a natural, reusable, and side-effect-free way to boost their health, the iron fish offers a practical solution. Regular use, combined with proper care, can contribute significantly to better iron status and overall well-being. For more information, you can visit the manufacturer's website: Lucky Iron Life.
