Iron is divided into heme iron from animal products and non-heme iron from plant products. For better absorption of the mineral, it is important to combine it with vitamin C.

Iron is one of the most important trace elements, without which the normal functioning of the human body is impossible. It is important to maintain the level of this trace element and remember that iron is divided into two types - heme and non-heme, which greatly affects the absorption of the element, writes UNN.

Details

The main physiological role of iron is its participation in the synthesis of hemoglobin, a specific protein of red blood cells that acts as a courier, delivering oxygen from the lungs to every cell, tissue, and organ of our body. In addition, iron is part of myoglobin, which supplies oxygen to muscles, and is also necessary for maintaining a healthy immune system, energy production, and DNA synthesis. A deficiency of this mineral leads to oxygen starvation, which manifests itself as chronic fatigue, pale skin, hair loss, brittle nails, dizziness, and reduced concentration.

Heme iron

Heme iron is found exclusively in animal products. Its main advantage is its extremely high bioavailability: the body is able to absorb 15% to 35% of this mineral without hindrance, as it is absorbed in the intestine in an unchanged form.

Liver and offal are absolute leaders in nutrient concentration. One hundred grams of beef, pork, or chicken liver can contain 6 to 9 milligrams of high-quality iron. In addition, offal such as kidneys, heart, or tongue are powerful sources of B vitamins, copper, selenium, and vitamin A.

Beef, veal, and lamb are a classic, most popular, and very reliable way to prevent anemia. A portion of quality lean beef weighing one hundred grams provides the body with approximately 2.5–3 milligrams of heme iron. An important rule: the darker the meat, the more myoglobin and, accordingly, iron it contains.

Shellfish and seafood are a real superfood. Just one hundred grams of oysters or mussels can contain up to 3 milligrams of the mineral, as well as a colossal amount of zinc, which is necessary for immunity.

Poultry and eggs also contain enough iron. Although chicken breast contains little iron, dark poultry meat, i.e., chicken thighs or turkey drumsticks, is a significantly more valuable source. Egg yolks also contain heme iron, about 1 milligram in two large eggs, which makes them an excellent addition to a daily breakfast.

Sardines, tuna, mackerel, salmon, and other fish are not only a source of omega-3 fatty acids but also supply the body with 1 to 2 milligrams of iron per hundred grams of product.

Non-heme iron

Non-heme iron is found in plant-based products. Although quantitatively there may be significantly more of it than in meat, the body absorbs it much worse, only at the level of 2–20%. That is why vegetarians and vegans need to carefully plan their diet.

Legumes, such as lentils, especially red and green, chickpeas, white, black, and red beans, peas, are the basis of an iron-rich plant-based diet. One cup of cooked lentils provides about 6.5 milligrams of non-heme iron, as well as a huge amount of plant protein and fiber.

Pumpkin seeds are a real record holder: one hundred grams of raw seeds contain an impressive 9 milligrams of the mineral. Sesame, especially in the form of tahini paste, flax seeds, cashews, almonds, and pine nuts are also extremely useful and concentrated sources.

Dark green leafy vegetables, including spinach, kale, arugula, and Swiss chard, are often mentioned by nutritionists. One hundred grams of raw spinach contain about 2.7 milligrams of iron. However, spinach contains oxalates, which hinder absorption, so it is better to consume it after light heat treatment - blanching.

Quinoa and whole grains. Quinoa is a gluten-free pseudocereal, one cup of which, when cooked, contains almost 3 milligrams of the mineral. Buckwheat, long-cooking oatmeal, and amaranth also make a significant contribution to the daily norm.

Real dark chocolate with a cocoa content of 70% to 85% is not only an exquisite dessert. A small portion of 30 grams supplies about 3.3 milligrams of iron, and is also a powerful source of antioxidants and magnesium.

Traditional Asian soy products, such as tofu and tempeh, contain about 3–4 milligrams of iron per half cup, making them an excellent alternative to meat.

Secrets and rules for maximum absorption

The presence of iron in a product absolutely does not guarantee that your body will receive and use it for its intended purpose. The absorption process in the gastrointestinal tract is very capricious.

The main helper in the absorption of non-heme (plant) iron is vitamin C. If you eat lentil porridge or spinach salad, be sure to add bell peppers, fresh tomatoes, or generously sprinkle the dish with lemon juice. This increases the percentage of mineral absorption several times. Foods rich in vitamin A and beta-carotene, such as carrots, pumpkin, or sweet potatoes, also contribute to better absorption.

What hinders iron absorption

Tannins and polyphenols are substances found in large quantities in black and green tea, coffee, cocoa, and red wine. These substances firmly bind the mineral and remove it from the body in transit. It is better to drink coffee or tea an hour before or two hours after a meal.
The only mineral that is a serious competitor and blocks the absorption of both heme and non-heme iron is calcium. Therefore, you should not drink milk with a beef steak, combine liver pate with a large amount of cream cheese, or take calcium supplements with iron-containing food.
Phytic acid is found in whole grains, bran, legumes, and seeds. To neutralize phytates and "unblock" iron, it is recommended to soak cereals and nuts in water overnight before cooking, sprout them, or use the fermentation method.

It is important to remember that an excess of iron in the body is no less dangerous than its deficiency, as it has a toxic effect on the liver and heart. Therefore, only a doctor should diagnose a deficiency and prescribe pharmacy drugs based on a detailed blood test, while a balanced and varied diet remains the safest and most natural way to maintain health.
