1. iron and mental performance: how it affects your brain

Iron is an essential trace mineral that plays a significant role in supporting mental performance and brain health. It affects the brain in a variety of ways and is critical to several processes. One of the most important functions of iron in relation to the brain is its contribution to oxygenation. Iron is an essential component of hemoglobin, which is found in red blood cells and is responsible for transporting oxygen around the body. The brain is an energy-intensive organ and requires about 20% of the oxygen available in the body to function optimally. Adequate iron levels ensure that the brain is supplied with sufficient oxygen, which is essential for optimal brain function and cognitive performance. In addition, iron plays an important role in energy production in the brain. As a component of the enzyme cytochrome c oxidase, iron is involved in the mitochondrial respiratory chain, which is responsible for converting nutrients into energy (adenosine triphosphate, ATP). Well-functioning energy production in the brain is crucial to maintain brain function and support mental performance. Iron is also involved in the synthesis of neurotransmitters, the chemical messengers responsible for communication between nerve cells. Neurotransmitters such as dopamine, serotonin and norepinephrine play a key role in regulating mood, motivation, attention and other cognitive functions. Adequate iron levels in the brain are therefore important to maintain the balance and function of these neurotransmitters. Furthermore, iron contributes to myelination in the brain. Myelin is a fat-rich substance that coats nerve fibers and increases the speed and efficiency of nerve impulse transmission. Good myelination is essential for efficient communication between nerve cells and thus for optimal brain function. Although iron is essential for brain function and mental performance, an imbalance in iron metabolism can also lead to oxidative stress. Excess iron in the brain can promote the formation of free radicals, which can lead to cellular damage. It is therefore important that iron status is well balanced to protect the brain from oxidative stress. An iron-rich diet is critical to support brain health and mental performance. Foods such as red meat, poultry, fish, legumes, green leafy vegetables, nuts and seeds are excellent sources of iron. To improve iron absorption from plant sources, you can combine iron-rich foods with vitamin C-rich foods, as vitamin C promotes iron absorption. It is important to keep track of iron levels and use supplements as needed under medical supervision. Balanced iron status supports brain health and can help improve cognitive functions such as memory, attention and mental clarity. A healthy brain is key to a fulfilling and productive life.

2. iron-rich diet for brain health

An iron-rich diet plays a significant role in brain health and can improve cognitive function and overall well-being. Here are some important points about the importance of an iron-rich diet for brain health:

Oxygenation of the brain: Iron is an essential component of hemoglobin, the protein in red blood cells that carries oxygen around the body. The brain needs an adequate supply of oxygen to function optimally. Iron deficiency can lead to decreased oxygen supply to the brain and impair mental performance.

Neurotransmitter synthesis: Iron plays an important role in the synthesis of neurotransmitters, the chemical messengers responsible for communication between nerve cells in the brain. Neurotransmitters such as dopamine, serotonin and norepinephrine affect mood, memory and concentration.

Improving cognitive function: studies have shown that adequate iron intake may be associated with better cognitive function, including memory, attention, and information processing speed.

Prevention of mental fatigue: iron deficiency can lead to fatigue and exhaustion, which can negatively impact mental performance. Adequate iron intake can help reduce fatigue and increase mental energy.

Mood regulation: Iron also plays a role in the synthesis of serotonin, a neurotransmitter important for mood regulation. Balanced iron levels can help reduce the risk of mood swings and depression.

To promote an iron-rich diet for brain health, include the following iron-rich foods in your diet:

  • Red Meat: Red meats such as beef, pork, or lamb are an excellent source of heme iron that is well absorbed by the body.
  • Poultry: chicken and turkey also contain easily digestible iron. Fish and seafood: Fish varieties such as tuna, salmon and mussels are rich in iron.
  • Legumes: beans, lentils and chickpeas are excellent plant sources of iron.
  • Green leafy vegetables: spinach, kale and Swiss chard are rich in non-heme iron. Nuts and seeds: Cashews, pumpkin seeds and sunflower seeds contain valuable iron.
  • Dried fruits: Dried apricots, raisins and prunes are also good iron-rich snacks.
  • To improve iron absorption from plant sources, you can combine iron-rich foods with vitamin C-rich foods, since vitamin C promotes iron absorption. For example, you can prepare a spinach salad with oranges or a lentil stew with tomatoes.

3. risk groups for iron deficiency

Iron deficiency is one of the most common nutrient deficiencies worldwide and can affect people of all ages and genders. However, there are certain populations that are at increased risk for iron deficiency due to lifestyle, certain diseases, or special circumstances. In this flow text, we will look in detail at the different risk groups for iron deficiency:

Pregnant women: Expectant mothers are particularly susceptible to iron deficiency because they have increased iron requirements during pregnancy. The growing baby and placenta require an adequate amount of iron for their development. In addition, morning sickness or a diet lacking in variety during early pregnancy can lead to lower iron absorption. If iron deficiency is not treated during pregnancy, it can lead to anemia, which can increase the risk of complications for both mother and baby.

Infants and young children: infants usually get enough iron from breast milk or special formulas. Over time, however, some infants may develop iron deficiency if they do not include enough iron-rich foods in their diet. Breastfed infants are particularly at risk because the iron content in breast milk decreases over time. Once solid foods are introduced into the diet, it is important to introduce iron-rich foods such as plant sources (e.g., legumes, whole grains) or iron-fortified baby foods.

Growing-age children: during growth, children need an adequate amount of iron to support the development of their organs and tissues. An active lifestyle and rapid growth can increase iron requirements. Children who have an unbalanced diet, especially if they eat little meat or other iron-rich foods, may be at increased risk for iron deficiency. Parents and caregivers should make sure their children are getting a varied diet that contains enough iron.

Vegetarians and vegans: people who eat only or mainly vegetarian or vegan diets may be at increased risk for iron deficiency. Plant sources contain so-called non-heme iron, which is not absorbed by the body as efficiently as heme iron from animal sources. Vegetarians and vegans must therefore take special care to consume iron-rich plant foods, such as green leafy vegetables, legumes, nuts and seeds. Simultaneous intake of foods rich in vitamin C may improve iron absorption from plant sources.

Women of childbearing age: Women who have their periods lose blood monthly, resulting in increased iron requirements. During menstruation, the body can lose a significant amount of iron, and if these losses are not compensated for by an iron-rich diet, iron deficiency can gradually develop. Some women also have heavier or longer periods, which further increases the risk. It is important that women of childbearing age maintain a balanced diet to meet their iron needs.

People with certain medical conditions or chronic blood loss: people with chronic medical conditions such as inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis) or celiac disease may be at increased risk for iron deficiency because these conditions can interfere with the absorption and transport of iron in the body. People who regularly donate blood or are prone to recurrent bleeding (e.g., gastrointestinal bleeding) may also be at higher risk for iron deficiency.

Elderly: Older people may be at increased risk for iron deficiency due to several factors. Some elderly people may have a limited dietary intake, resulting in lower consumption of iron-rich foods. In addition, the body's ability to absorb iron from food may decrease with age. The combination of these factors may put older people at increased risk for iron deficiency.

Athletes and people with intense physical activity: people who exercise regularly or are very physically active may be at increased risk for iron deficiency due to the increased iron demand of their muscles and increased oxygen demand. The body may require increased iron for energy production and oxygen transport, especially during endurance sports such as long-distance running or cycling. Athletes should ensure that they include sufficient iron-rich foods in their diet to meet their increased needs.

4. iron-containing dietary supplements

Anyone who wants to increase an iron level that is too low with a dietary supplement should definitely pay attention to the form of the active ingredient and its origin. Iron bisglycinate is particularly suitable for increasing iron levels. It is very well tolerated and is utilized by the body to a high degree. Likewise, the preparation should not contain any chemical additives such as magnesium stearate or microcrystalline cellulose. If you buy a preparation from Germany, you can be sure that the product has also been produced safely and is of high quality.
