Factors Affecting Iron Absorption
Vitamin C-rich foods
Consuming vitamin C-rich foods alongside iron-rich foods can enhance your body’s absorption of iron. Citrus fruits, berries, broccoli, and bell peppers are examples of vitamin C-rich foods that can be paired with iron sources to optimize iron absorption.
Calcium-rich foods
Calcium can inhibit the absorption of iron, so it is advisable to avoid consuming calcium-rich foods, such as dairy products, at the same time as iron-rich foods. Separating your intake of calcium and iron by a few hours can help maximize iron absorption.
Phytates and oxalates
Phytates and oxalates are naturally occurring compounds found in certain plant-based foods that can bind to iron and reduce its absorption. Soaking and sprouting legumes, grains, and seeds can help reduce the levels of phytates, while cooking vegetables can help reduce oxalate content. Consuming a varied diet that includes both cooked and raw foods can help mitigate the impact of these compounds on iron absorption.
Tea and coffee
Tea and coffee contain compounds called tannins that can inhibit iron absorption. It is suggested to avoid consuming tea or coffee for at least one hour before and after meals to maximize iron absorption. If you enjoy these beverages, consider opting for herbal teas or decaffeinated options, as they have a lower tannin content and are less likely to interfere with iron absorption.
Iron-Rich Cooking Tips

Cooking in a cast-iron skillet can help increase the iron content in your meals. The iron from the skillet can leach into the food during cooking, providing a small but valuable amount of iron. Incorporating foods such as meat, poultry, fish, or vegetables into your cast-iron cooking routine can help boost your iron intake.
Combining iron-rich foods with vitamin C-rich foods
As mentioned earlier, pairing iron-rich foods with vitamin C-rich foods can enhance iron absorption. For example, squeezing lemon juice over spinach salad or adding diced bell peppers to a lentil soup can help maximize the iron absorption from these foods. Be creative and experiment with different combinations to optimize your iron intake.
Soaking and sprouting legumes
Soaking and sprouting legumes, such as beans and lentils, before cooking can reduce the levels of phytates and increase iron availability. Simply soak the legumes overnight and rinse them before cooking. Sprouting involves soaking and rinsing the legumes over a few days until small sprouts appear. The sprouted legumes can then be cooked to enjoy their enhanced nutritional value.
Avoiding excessive use of calcium-rich ingredients
As previously mentioned, calcium-rich foods can inhibit iron absorption. While dairy products and calcium-rich ingredients have their own nutritional benefits, it is advisable not to consume them excessively or in large amounts alongside iron-rich foods. Be mindful of the amount of calcium-rich ingredients in your meals and strive for a balanced approach.
