Summary
The relationship between iron in drinking water and anemia prevention is vital in public health. Understanding anemia, its prevalence, and the importance of iron is crucial. Here’s a brief overview:
Understanding Anemia:
- Anemia is characterized by a lack of red blood cells or hemoglobin.
- Iron deficiency is a common cause of anemia.
- Symptoms include fatigue, weakness, and pale skin.
Iron levels in water and the prevention of anemia have been topics of recent studies and public health debate. Anemia is a condition where you have too few red blood cells or hemoglobin, and millions of people worldwide have it. Anemia is a leading cause of iron shortage and iron-enriched drinking water has even been proposed as a way to prevent it. It is imperative to know how iron in water can help prevent anemia if we are to devise strategies to enhance public health and decrease the incidence of anemia across the globe.
Understanding Anemia
Anemia is a medical illness in which the body lacks enough or the proper blood cells. When red blood cells don’t meet the requirement, oxygen can’t travel to other areas of the body; if the number is too low, then you don’t receive enough oxygen and you will become fatigued and weak. There are a number of different forms of anemia, but the most common is iron-deficiency anemia, where there isn’t enough iron to make enough red blood cells.
Why is iron important?
Iron is a mineral that we need for good health. It’s needed for hemoglobin, which is a protein that red blood cells make to transport oxygen throughout the body. Your body can’t make enough hemoglobin to make red blood cells without enough iron, which makes you anemic. Iron contributes not just to the production of red blood cells, but also to immune function, mental development and temperature control.
Iron Deficiency and Anemia
Iron deficiency is the most common cause of anemia in the world. It can be caused by any number of reasons such as bad diet, low iron uptake by the body, pregnancy, loss of blood, or some disorders. Iron deficiency anemia develops when the iron being consumed or absorbed cannot be made up for the iron lost by the body. Fatigue, pallor, bruising, vertigo and strange desires for non-nutritive things such as ice or dust are some symptoms of iron-deficiency anaemia.
What are the Sources of Iron?
There are plenty of foods that contain iron, and most frequently meat (particularly red meat, poultry, and fish). Vegan sources are beans, lentils, spinach, and vitamin-packed foods such as cereal. Iron pills are another common iron supplement that is often prescribed to those with iron-deficiency anemia, or at risk of iron deficiency (eg pregnant women). But there’s another iron-carrying source, often unmentioned: water.
Iron in Drinking Water
Iron is available in drinking water from nature or by tack work. Iron can naturally exist in groundwater, most of our drinking water, especially if it flows through iron-rich soil and rock. Iron content in groundwater is not always uniform across regions depending on the geology. Not only in nature, but in some public water supplies iron is also added to the water through a process called iron fortification.
Drinking Water as a Source of Iron
If you drink iron-enriched water, you’ll also boost your iron levels every day and avoid iron-deficiency anemia. What iron you obtain from water will be determined by the iron content of the water and the volume of water consumed. Even if drinking water isn’t going to provide all the iron you need – foods and, if you need supplements, they can still do the trick – it can add to your iron intake.
Iron Fortification in Drinking Water
In water supply, iron is infused into drinking water – a practice that has even been contemplated in some areas as a means of treating iron-deficiency anaemia. You can do this by adding iron to public water supplies, or by filtering your home with iron filters. Yet this can be effective only insofar as it depends on the bioavailability of the iron involved (ie, how easily it is assimilated by the body), whether the fortified water is tolerable for people (high iron concentrations can change water’s taste or colour), and the cost and feasibility of fortification programs.
Practical Tips for Preventing Iron Deficiency Anemia
Avoiding iron-deficiency anemia is usually as simple as increasing your iron levels. Some ways you can do that:
Keep iron in your diet: You can get iron from animal as well as plant sources in your diet. Iron-dense food like lean meats, seafood and poultry. Soy foods like beans, peas, lentils and green leafy vegetables such as spinach are all vegetarian. Iron-enriched cereals and bread are good sources of iron, too.
Iron rich water: If you have iron in your local water, then you can drink it to get your iron in. You may want to filter your water (not iron). A number of filters also leave in the water beneficial minerals such as iron.
Take iron supplements: If you have iron deficiencies — from a low-iron diet to pregnancy or a disease — your doctor may prescribe you an iron supplement. Always talk to a doctor before attempting a new supplement program.
Add iron with Vitamin C: Vitamin C will make your body take in iron. Make sure to take Vitamin C-containing foods or beverages (such as oranges or bell peppers) while you are eating iron-containing foods or taking an iron supplement.
