Iron plays a crucial role in keeping the body healthy and strong. It is used to make red blood cells that carry oxygen in the blood and supports energy production. For those following a vegan diet, getting enough iron can seem like a challenge. This is because plant-based iron is not the same as the iron found in animal products. This guide explains what iron is, why it matters, the difference between types of iron, the best vegan sources, and how to improve iron absorption.
What Iron Does and Why We Need It
Iron is a mineral essential for many bodily functions, including carrying oxygen around our body. Without enough iron, the body struggles to produce enough healthy red blood cells, leading to fatigue, weakness, and a weakened immune system.
Iron also supports brain function and muscle metabolism. Maintaining adequate iron levels is key to feeling energetic and staying strong, especially for people on a vegan diet who don't get iron from animal sources.
Difference Between Heme Iron and Non-Heme Iron
Iron comes in two forms: heme and non-heme. Heme iron is only found in animal products like meat, poultry, and fish. It is absorbed by the body more efficiently, with an absorption rate of about 15-35%.
Non-heme iron is found in plant foods such as beans, lentils, spinach, and fortified cereals. The body absorbs non-heme iron at a lower rate, roughly 2-20%. Factors like other nutrients in the meal can either boost or inhibit this absorption.
This isn't entirely a bad thing, as reducing the absorption of iron can prevent iron overload, which causes symptoms like nausea and stomach pain. However, since vegans rely entirely on non-heme iron, understanding how to maximise its absorption is important for maintaining healthy iron levels.
Top 10 Vegan Sources of Iron
Here are ten plant-based foods rich in iron that can help vegans meet their daily needs. Try to include them in your diet on a regular basis:
Lentils: One cup cooked contains about 6.6 mg of iron. Lentils are versatile and easy to add to soups, salads, and stews.
Chickpeas: One cup cooked offers around 4.7 mg of iron. Use them in hummus, curries, or roasted as a snack.
Tofu: Half a cup provides about 3.4 mg of iron. Tofu absorbs flavours well and works in stir-fries or grilled dishes.
Spinach: One cup cooked has roughly 6.4 mg of iron. Add it to smoothies, pasta, or sauté as a side.
Quinoa: One cup cooked contains 2.8 mg of iron. It’s a great base for salads or bowls.
Pumpkin seeds: One ounce offers 2.5 mg of iron. Sprinkle on salads or eat as a snack.
Black beans: One cup cooked provides 3.6 mg of iron. Use in chilli, burritos, or salads.
Fortified cereals: Many plant-based cereals are fortified with iron, often providing 4-18 mg per serving.
Swiss chard: One cup cooked has about 4 mg of iron. Use it in sautés or soups.
Dried apricots: Half a cup contains 1.7 mg of iron. Great for snacking or adding to oatmeal.
Including a variety of these foods daily helps ensure a steady iron intake. You don't need to eat all of them, you can pick your favourites and add in the other for variety as you choose.
How to Boost Iron Absorption on a Vegan Diet
There are certain strategies that you can use to increase the amount of iron that you absorb from foods. This can make getting enough iron easier and stress-free:
Eat vitamin C-rich foods with iron sources
Vitamin C can increase iron absorption by converting it into a form the body can absorb better. Add citrus fruits, bell peppers, strawberries, or tomatoes to meals with iron-rich foods.
Avoid drinking tea or coffee with meals
These beverages contain compounds called polyphenols that reduce iron absorption. Try to drink them between meals instead.
Limit calcium intake during iron-rich meals
Calcium can interfere with iron absorption. If you consume calcium supplements or calcium-rich foods, take them at different times from iron-rich meals.
Cook with cast-iron cookware
Cooking acidic foods like tomato sauce in cast-iron pans can increase the iron content of the meal.
Soak, sprout, or ferment beans and grains
These processes reduce phytates, compounds that block iron absorption, making the iron more available.
Combine different iron sources
Mixing legumes with leafy greens or seeds can improve overall iron intake and absorption.
Final Thoughts on Iron for Vegans
Getting enough iron on a vegan diet is something that we need to be aware of, but it is entirely possible with the right foods and habits. Focus on including a variety of iron-rich plant foods daily and pair them with vitamin C sources to boost absorption. Avoid drinking tea or coffee with meals and consider cooking methods that increase iron content.
By understanding the difference between heme and non-heme iron and using these practical tips, vegans can maintain healthy iron levels, supporting strong bodies and active lifestyles.
