Live a healthier life: Why iron is so important and where you can find it

Table of contents

When many people think of foods containing iron, they immediately think of spinach. That's not wrong, but it's also by no means all that nature offers us in terms of iron sources! Spinach was once celebrated as an iron-rich champion until more precise measurements revealed a calculation error. Nevertheless, spinach continues to play in the league of top sources of iron.

Other foods are also packed with this essential trace element. The heavyweights among iron-containing foods include whole grain products, meat, sausage products, various vegetables and legumes. Grains and legumes are real iron heroes, especially for those who follow a vegan or vegetarian diet.

But why is it so important to eat a diet rich in iron? Because iron plays a central role in transporting oxygen in our blood. If there is a deficiency because we do not absorb enough iron through food, our body's oxygen supply suffers. The consequences? Fatigue creeps in, concentration wanes and mood drops. So, let's keep a close eye on our iron levels - for more energy and joy of life!

How much iron do we need?

In order to prevent deficiency symptoms, regular consumption of foods containing iron is essential. This is the only way to easily meet your daily iron requirements.

However, the daily iron requirement depends on individual factors such as age and gender. On average, women need more iron than men. Children, on the other hand, get by with less iron than adults. A conscious approach to our diet is therefore essential for optimal iron supply!

DieGerman Society for Nutritionrecommends the following reference values ​​for iron intake:

The iron requirements of babies & children (in mg/day):

  • Infants up to 4 months: 0.5 mg
  • Infants up to 11 months: 8 mg
  • Children 1 to 9 years: 8-10 mg

The iron requirement of Adolescents (in mg/day):

  • Boys 10 to 19 years: 12 mg
  • Girls 10 to 19 years: 15 mg

The iron requirement of adults (in mg/day):

  • Men aged 19 and over: 10 mg
  • Women 19 to 50 years: 15 mg
  • Women > 50 years: 10 mg

A woman's iron requirements in the event of pregnancy (in mg/day):

  • Pregnant women 30 mg
  • Breastfeeding 20 mg

Research results reveal that many people in Germany do not consume enough iron-containing foods and, above allWomenoften suffer from a slight undersupply. Vegetarians and vegans in particular should pay more attention to adequate iron supply. This is actually not difficult if you know which foods are particularly rich in iron.

Why are women's iron needs higher?

This explains why women lose an average of 15 mg of iron during their monthly periodsFederal Center for Nutrition. It is therefore particularly important that you pay attention to your iron intake. Although 15 mg per month, or about 0.5 mg per day, doesn't sound like much, iron absorption from food depends on numerous factors and is often not particularly efficient. In addition, women tend to eat less meat and less frequently than men. Women who tend to have low iron levels should make sure to eat meat or sausage products regularly (1-2 times per week), as well as iron-rich vegetables such as kale or spinach and legumes (about 1 serving per week). A salad with red pepper during a meal or fruit as a dessert can also be useful, as the vitamin C it contains improves iron absorption.

That's why we present you a range of iron-rich foods - from meat to vegetarian and vegan options. So you are well equipped to deal with a possible...to prevent effectively.

How does the body best absorb iron?

In order to really make full use of the particularly valuable components of food, i.e. minerals, trace elements or fatty acids, foods sometimes have to be combined. Their interaction then brings out the maximum of good components. It's best to eat all foods regularly, because the iron from them is utilized differently by our bodies.

The body absorbs iron from animal foods particularly well, while it has difficulty absorbing iron from plant foods such as vegetables or grains. That's why the following applies: Combine plant-based iron-containing foods with something, which improves iron absorption in the body.

An example:Enjoy to theHave a glass of orange juice at breakfast or eat a few berries or other fruit for dessert.

Good to know: ,oron the other hand, hinder iron absorption in the body!
