Boosting Ferritin Levels: Vegan Diet Strategies And Tips

Maintaining healthy ferritin levels is essential to prevent iron-deficiency anaemia. While it is generally agreed that vegetarians and vegans tend to have lower blood iron levels than meat-eaters, it is still possible to get enough iron from a vegan diet. This article will explore how to raise ferritin levels on a vegan diet.

Eat iron-rich foods such as tofu, tempeh, beans, legumes, nuts, seeds, and whole grains

Tofu, tempeh, beans, legumes, nuts, seeds, and whole grains are all great sources of iron for vegans. As iron is mostly found in animal products, vegans may need to pay more attention to their iron intake. However, these plant-based foods can help vegans meet their necessary iron intake.

Tofu and Tempeh

Tofu is a well-known meat substitute and a great source of complete protein. A half-cup of firm tofu provides 3mg of non-heme iron, which is slightly more than the average serving of red meat. Tofu is also a heart-healthy choice, as it contains less saturated fat than red meat.

Legumes, including high-quality soy-based foods like tofu and tempeh, are also an excellent source of iron. In addition, they are packed with other essential nutrients such as fibre, B vitamins, folate, calcium, potassium, phosphorus, and zinc.

Beans and Legumes

Legumes, including beans, peas, and lentils, are fantastic sources of iron. For example, a cooked 150g serving of lentils provides 5mg of iron, which is nearly half of the daily requirements for men and a third of the requirements for women.

Additionally, beans are a nutritional powerhouse, providing plant-based protein and fibre. They can also help lower cholesterol and control blood sugar levels. Pairing beans with citrus fruits can enhance the absorption of non-heme iron.

Nuts and Seeds

Nuts and seeds are excellent plant-based sources of iron. For instance, pistachios are the nut variety with the highest iron content, containing 14mg of iron per 100g. Just a handful of nuts or seeds can provide a meaningful dose of iron, along with other essential nutrients.

Sesame seeds are the highest in iron among common seeds, with 14.6mg of iron per 100g serving. Pumpkin seeds, hemp seeds, and chia seeds also have high iron content, ranging from 7-9mg of iron per serving.

Whole Grains

Whole grains maintain their naturally occurring minerals, including iron, as they undergo less processing than refined grains. Combining a whole grain with iron-rich vegetables, herbs, spices, and a glug of olive oil can create a nutritious and delicious dish.

Additionally, some whole grain breakfast cereals like Cheerios and Special K are fortified with iron, providing up to 100% of the daily iron RDA.

Pair iron-rich foods with vitamin C-rich foods to enhance absorption

To boost your ferritin levels on a vegan diet, it is important to pair iron-rich foods with vitamin C-rich foods. This is because vitamin C enhances the absorption of non-heme iron, which is the type of iron found in plant-based foods.

First, understand that non-heme iron, found in vegan foods, is not as easily absorbed as heme iron, which is found in animal products. Therefore, vegans may need to pay more attention to their iron intake and absorption.

Second, focus on including a source of vitamin C with your iron-rich plant foods. For example, you could pair cooked spinach, asparagus, or green beans with citrus fruits or red/green bell peppers. You could also add vitamin C-rich fruits like kiwis, strawberries, or tomatoes to your meals.

Third, be mindful of foods that can hinder iron absorption. For example, coffee, tea, and soda can reduce iron absorption, so it is best to avoid consuming them with your iron-rich meals or snacks. Similarly, dairy products and calcium supplements can interfere with iron absorption.

Finally, consider using cast-iron cookware. Cooking meals in cast iron pots and pans can increase the iron content of your food by up to 16%.

By following these tips, you can enhance your body's ability to absorb non-heme iron and work towards raising your ferritin levels while maintaining a vegan diet.

Avoid tea, coffee, and dairy when consuming iron-rich foods

Raising ferritin levels on a vegan diet can be challenging due to the lower absorption rate of non-heme iron, which is the type of iron found in plant-based foods. However, there are strategies to optimise iron absorption and increase ferritin levels while adhering to a vegan diet. One crucial recommendation is to avoid tea, coffee, and dairy when consuming iron-rich foods.

Tea, coffee, and dairy products can significantly hinder the absorption of iron, especially when consumed with meals containing iron. The presence of polyphenols, such as chlorogenic acid and tannins, in tea and coffee reduces iron absorption. For instance, a cup of coffee with a hamburger meal reduced iron absorption by 39%, while tea decreased it by 64%. The inhibitory effect is concentration-dependent, meaning the stronger the tea or coffee, the greater the reduction in iron absorption. Therefore, it is advisable to refrain from drinking tea or coffee with meals or shortly after to maximise iron absorption from plant-based sources.

Dairy products, including milk and yoghurt, are also known to impede iron absorption. Calcium, a mineral abundant in dairy, can interfere with the body's ability to absorb iron. Hence, it is recommended to avoid consuming dairy products alongside iron-rich foods or supplements. Separating the consumption of dairy and iron-rich foods by at least two hours can help mitigate this issue.

In addition to avoiding tea, coffee, and dairy, there are other strategies to enhance iron absorption. Consuming vitamin C-rich foods, such as citrus fruits, red peppers, or kiwis, alongside iron-rich meals can significantly improve iron absorption. Additionally, opting for cast-iron cookware can contribute trace amounts of iron to your diet.

While it is important to ensure adequate iron intake, excessive iron supplementation can lead to unpleasant side effects and, in rare cases, organ damage. Therefore, it is always advisable to consult a healthcare professional before starting an iron supplementation regimen. They can provide guidance on appropriate dosages and help monitor your ferritin and iron levels to ensure they remain within a healthy range.

Use cast-iron cookware to increase the iron content of meals

Using cast-iron cookware is a natural way to increase the iron content of your meals. Compared to using non-stick cookware, cast-iron pots and pans may increase the iron content of the foods cooked in them by up to 16%. This increase is due to the transfer of iron molecules from the cast-iron surface to the food during the cooking process.

The amount of iron that is absorbed by the food depends on several factors, including the age and size of your cast-iron cookware, as well as the cooking time and type of food being cooked. For example, you may get more iron from simmering a moist food, like spaghetti sauce, in a cast-iron pot than from frying meat in a cast-iron pan. Additionally, certain foods such as tomatoes and tomato-based products, wine, and vinegar may not be well-suited for cooking in regular cast-iron cookware as their natural acidity can weaken the seasoned coating on the porous cast-iron surface, resulting in metallic flavours leaching into the food. However, you can still cook these foods in cast iron by diluting acidic ingredients, adding them towards the end of cooking, or reducing their cooking time.

Cast-iron cookware can be a great way to increase the iron content of your meals, especially if you are looking for a natural and convenient way to boost your iron intake. It is important to note that the iron provided by cast-iron cookware is non-heme iron, which is not as easily absorbed by the body as heme iron found in animal products. Nonetheless, for those with iron deficiencies, any additional source of iron can be beneficial.

Take iron supplements if necessary, but be cautious of potential side effects

Iron supplements can be an effective way to increase ferritin levels, but they should be approached with caution. While iron is essential for good health, too much can be harmful. Excess iron can damage organs and cause side effects such as constipation and heartburn. Therefore, it is important to follow the dosing instructions provided by a healthcare professional and to be mindful of the form of iron they suggest, as there are many available (e.g. ferrous sulfate, ferrous fumarate, ferrous gluconate) and not all will be suitable for everyone.

The optimal dose will depend on your baseline hemoglobin, serum iron and ferritin levels. Generally, it can take three to six months at a daily dose of 100 to 200 mg of elemental iron per day to replenish iron stores. However, symptoms of iron deficiency anemia may improve within a week or a month. Research suggests that intermittent iron supplementation (as opposed to daily) may be equally effective while reducing side effects. Higher doses are typically spread across two daily doses to improve absorption. Iron is best absorbed on an empty stomach, but this can cause digestive issues for some people. In this case, it is fine to take the supplement with meals, especially meals containing vitamin C, which aids absorption. It is important to avoid milk, caffeine, antacids and calcium supplements when taking iron supplements, as these can hinder absorption.
