Why do we need iron?
Iron is a mineral that plays an important role in the functioning of the body. It’s an essential component of hemoglobin. Hemoglobin is a protein that is in your red blood cells, they are responsible for the transport of oxygen in your body. If you have a shortage of iron, then there is a shortage of oxygen that is being transported through your body.
This is why you’ll feel dizzy, fatigued, have a lot of headaches if you have a shortage of iron. And some effects can be even worse: There is a high risk of palpitations. Iron is also needed to create antibodies that help your body to protect you against diseases. Besides that, iron helps to break down harmful substances in your body.
How much iron should I eat?
A healthy body contains 800 to 1500 mg of iron. It’s essential to keep up your iron stock on the right level. Therefore men need to consume 11 mg of iron per day, for women 15 mg of iron per day is recommended.
Children and teenagers need more iron than average. This is because they are still growing. For small children, it’s important to be alert on their iron intake.
Can you get enough protein as a plant-based athlete?
People that follow a vegetarian or a vegan diet belong to the group that risks having a shortage of iron. The average person gets mostly its daily iron needs out of meat, which is not, of course, not included in vegetarian and vegan diets. This is why you need to pay attention to your iron intake as a vegan.
However, it is not impossible. The iron found in plant-based foods is called non-heme iron. Non-heme iron is unfortunately not absorbed as well as the heme form in animal products.
It’s commonly thought that vegetarians and vegans are more prone to an iron deficiency because of this. However different studies have shown that these diets contain just as much iron, if not more, than diets containing meat.
But, although vegans may consume as much as meat-eaters, there still is a greater risk of deficiency because of the non-heme iron. That’s why it’s recommended that vegetarians and vegans multiply their recommended iron take by 2 times to compensate for the reduced absorption.
Next, to taking supplements, there is another way to improve the absorption of iron. It’s eating more food! Some foods can enhance your body’s ability to absorb iron even better. Vitamin C has been shown to enhance iron absorption.
It captures non-heme iron and stores it in a form that’s more easily absorbed by your body. Foods high in vitamin C include citrus fruits, dark green leafy vegetables, bell peppers, melons, and strawberries.
Can you eat too much iron?
Iron toxicity from food sources is uncommon. Once you consume your food, your body has its own balancing system to make certain that it gets just enough and break off the unneeded iron. Nevertheless, one report showed that deadly overdoses were possible with excessive intakes of iron supplements. So, be careful with the supplements you take! Excessive iron levels can also occur in some people with a condition called hemochromatosis.
This is usually caused by a gene that enhances absorption. Additionally, consuming too much iron over time may cause large deposits of it to form in the liver and other tissues. Consequently, it may lead to diabetes, heart disease, and liver damage. This is why you never should take an iron supplement unless when recommended to you by a health professional.
