I recently discovered I was slightly deficient in iron (its medical term is sideropenia), and naturally, I wanted to resolve this in the healthiest way possible. It all started when I began feeling unusually fatigued, even after a full night’s sleep. My energy levels were low, I often felt dizzy, and I struggled to concentrate. At first, I thought it was just stress or lack of sleep, but after noticing my pale complexion and frequent headaches, I decided to dig deeper.
After discussing my symptoms with my doctor, they suggested a blood test to check my iron levels. The results showed that while I wasn’t severely anemic, my iron levels were lower than optimal, which explained my symptoms. My doctor recommended dietary changes before considering supplements, and I was eager to explore natural ways to boost my iron intake.
Rather than jumping straight to supplements, I explored natural dietary sources of iron and simple ways to enhance my body’s ability to absorb it. Here are ten natural ways to increase iron intake through food and smart nutritional choices to combat iron deficiency.
1. Eat More Red Meat and Organ Meats
Red meat, such as beef and lamb, is one of the richest sources of heme iron, the form that is easiest for the body to absorb. Organ meats like liver are even more potent, making them a great option for quickly boosting iron levels. Liver, in particular, is packed with essential vitamins like B12, folate, and vitamin A, making it a powerhouse food. While some people might not enjoy the taste, there are ways to prepare it that make it more palatable. Mixing it into ground beef, making pâté, or combining it with flavorful herbs and spices can help make it more enjoyable.
2. Incorporate Shellfish into Your Diet
Shellfish, particularly clams, oysters, and mussels, are packed with iron. A small serving can provide a significant portion of the daily recommended intake, and since it’s heme iron, it’s highly bioavailable. Clams, for example, contain up to 28 mg of iron per 100 grams, which is more than most meats. Besides iron, shellfish also provide zinc, protein, and healthy omega-3 fatty acids. They can be prepared in various ways, including steaming, grilling, or adding them to soups and pasta dishes. Consuming shellfish regularly can support overall health while ensuring optimal iron levels.
3. Load Up on Dark Leafy Greens
Vegetables like spinach, kale, and Swiss chard are excellent sources of non-heme iron. While non-heme iron isn’t as easily absorbed, pairing it with vitamin C-rich foods can significantly enhance absorption. These greens are also packed with fiber, antioxidants, and other essential vitamins like vitamin K and folate. A simple way to incorporate more greens into your diet is by adding them to smoothies, omelets, salads, or stir-fries. Cooking these greens can also reduce their oxalate content, which helps improve iron absorption. Adding a squeeze of lemon juice can further enhance their benefits.
4. Pair Iron-Rich Foods with Vitamin C
Eating foods high in vitamin C, such as oranges, bell peppers, and tomatoes, alongside iron-rich foods can improve absorption. This is especially important for those relying on plant-based sources of iron. Vitamin C helps convert non-heme iron into a more absorbable form. For example, adding bell peppers to a spinach salad or drinking a glass of orange juice with an iron-rich meal can boost iron levels significantly. Including strawberries, kiwi, and citrus fruits as snacks or in meals is another simple way to ensure better iron absorption while benefiting from the immune-boosting properties of vitamin C.
5. Consume More Legumes
Beans, lentils, chickpeas, and peas are fantastic plant-based sources of iron. They are also rich in protein and fiber, making them a great choice for vegetarians and vegans looking to boost their iron intake. A single cup of cooked lentils can provide up to 6.6 mg of iron, which is about 37% of the daily recommended intake. Soaking or sprouting legumes before cooking can help reduce phytates, which can inhibit iron absorption. Including legumes in stews, salads, or hummus recipes can provide a tasty and nutritious way to increase iron intake while promoting overall digestive health.
6. Snack on Nuts and Seeds
Pumpkin seeds, sesame seeds, and cashews contain notable amounts of iron. They’re an easy and convenient snack that can be sprinkled over meals or eaten on their own. A handful of pumpkin seeds can provide around 4.2 mg of iron, making them a great option for daily snacking. These seeds and nuts are also high in healthy fats, magnesium, and protein. Adding them to yogurt, oatmeal, or trail mix can help diversify your diet while ensuring steady iron intake. Opting for unsalted and raw varieties can help maximize their nutritional benefits without excess sodium.
7. Opt for Fortified Foods
Many cereals, breads, and plant-based milk alternatives are fortified with iron. Checking labels and choosing iron-fortified options can help bridge any dietary gaps. Some breakfast cereals provide up to 100% of the daily recommended iron intake, making them an excellent choice for individuals struggling to meet their iron needs through whole foods alone. Fortified plant-based milks like soy or almond milk can be another valuable source for vegans and vegetarians. When selecting these products, opting for varieties with low sugar content ensures you reap the benefits without excessive added sugars.
8. Cook with a Cast-Iron Skillet
Cooking acidic foods, such as tomatoes, in a cast-iron skillet can actually increase the iron content of your meals. This is a simple and natural way to boost your intake without changing your diet drastically. Studies show that food cooked in cast iron can absorb small amounts of iron from the cookware, particularly when simmering acidic foods like tomato sauce. Regularly using cast-iron cookware for meal preparation is an effortless way to increase daily iron intake, especially for those who may struggle to get enough through diet alone.
9. Reduce Intake of Iron Inhibitors
Certain foods and drinks, like coffee, tea, and calcium-rich dairy, can interfere with iron absorption. Try to consume these separately from iron-rich meals to maximize absorption. Tannins in tea and coffee bind to iron and reduce its bioavailability, while calcium competes with iron for absorption in the gut. If you enjoy tea or coffee, try drinking it between meals rather than with meals. Similarly, consuming dairy products at different times of the day can help maintain optimal iron absorption. Making these small adjustments can significantly impact iron levels over time.
10. Add More Dried Fruits to Your Diet
Dried fruits, such as apricots, raisins, and prunes, contain good amounts of iron. They make for a tasty and nutritious snack while contributing to your daily iron intake. A quarter-cup of dried apricots provides about 1.2 mg of iron, along with fiber and antioxidants. These fruits are great for adding natural sweetness to meals without refined sugars. They can be included in breakfast cereals, trail mix, or even desserts. Since dried fruits are calorie-dense, consuming them in moderation while balancing with other whole foods ensures a well-rounded, iron-rich diet.
