Absorption of dietary iron is increased by eating iron-rich foods with vitamin C foods (citrus fruits) and lactic acid (sauerkraut and yogurt). Cooking food in cast-iron pots can also add to their iron content.
Vitamin A increases the absorption of magnesium.
Increase it
There are several dietary factors that can potentially decrease the absorption of iron in a meal. For instance, foods that contain calcium, such as dairy products, milk, cheese, etc. will interfere with the absorption of iron into the bloodstream.

According to the National Institute of Health, orange juice increases the absorption of non-heme iron. Eataing Vitamin C-rich foods will aslo help increase the absorption of iron.
Nonheme iron is plant-sourced iron, as opposed to animal-sourced iron. Acidic foods and foods rich in vitamin C greatly increase the absorption, so lemonade or orange juice would be great for this purpose.

The relationship between iron stores and the percentage of iron absorbed is inversely correlated. When iron stores are low, the body increases the absorption of dietary iron to compensate for the deficiency, leading to a higher percentage of iron absorbed. Conversely, when iron stores are sufficient or high, the body reduces absorption, resulting in a lower percentage of iron absorbed. This regulatory mechanism helps maintain iron homeostasis in the body.
The dietary fibres increase the amount of bowel. So the foods cannot stay on the intestine for longer period, the absorption of unsaturated fat reduce by.
Iron is not well absorbed from the intestinal tract primarily due to its chemical form and the presence of dietary inhibitors. Non-heme iron, the type found in plant sources, is less bioavailable than heme iron from animal sources. Additionally, factors like phytates, polyphenols, and calcium can hinder iron absorption by binding to it or competing for absorption sites in the gut. The body's regulation of iron absorption also means that excess iron is not readily absorbed to prevent toxicity.
A good that enhances nonheme iron absorption is vitamin C. Foods rich in vitamin C, such as citrus fruits, strawberries, and bell peppers, can significantly increase the absorption of nonheme iron from plant sources and fortified foods. Consuming these vitamin C-rich foods alongside nonheme iron sources can improve overall iron status and help prevent iron deficiency.
