Sesame Seeds: A powerful contender

Often overlooked, sesame seeds are a nutritional powerhouse, making a strong case for being the best seed for iron deficiency. According to one analysis, 100 grams of sesame seeds contain approximately 9.5 milligrams of iron, while another source notes around 14.6 milligrams per 100 grams, fulfilling a significant portion of the daily requirement. This impressive iron content is supported by the presence of other vital nutrients like copper, which assists in iron metabolism.

Sesame seeds also offer a wide array of other health benefits. They are a great source of calcium, magnesium, zinc, and fiber. Studies also suggest that sesame seeds have antioxidant properties, which can help protect cells from free radical damage and support the immune system.

Pumpkin Seeds: A popular and rich option

Pumpkin seeds, or pepitas, are another excellent source of iron. A 100-gram serving can provide around 8.8 mg of iron, contributing significantly to daily needs. A smaller, more realistic 1-ounce (28-gram) serving contains approximately 2.5 mg of iron, which is about 14% of the daily value. Research has explored the potential of pumpkin seeds as a natural remedy for anemia due to their rich profile of iron, zinc, and magnesium, all of which are essential for hemoglobin production.

Beyond iron, pumpkin seeds are high in magnesium, which supports muscle and nerve function and helps regulate blood sugar. They are also a good source of healthy fats, protein, and antioxidants.

Chia Seeds: More than just fiber

While known for their high fiber content, chia seeds also provide a decent amount of iron. A 100-gram serving contains around 5.7 to 7.7 mg of iron, depending on the source. The high fiber content of chia seeds is beneficial for digestion and can help with detoxification. Additionally, they are packed with omega-3 fatty acids, which have anti-inflammatory properties and support heart health.

Other notable seeds

• Flaxseeds: While their iron content is lower per serving than sesame or pumpkin seeds, flaxseeds are a valuable source of omega-3 fats, fiber, and lignans, which may assist with iron absorption. Grinding flaxseeds is crucial for proper digestion and nutrient absorption.
• Hemp seeds: Often called a nutritional powerhouse, hemp seeds offer approximately 8 mg of iron per 100 grams. They provide all nine essential amino acids and are rich in omega-3 and omega-6 fatty acids, beneficial for heart health.
• Sunflower seeds: A 100-gram serving of sunflower seeds contains about 5.3 mg of iron. They are also an excellent source of vitamin E, magnesium, and selenium.

Maximizing non-heme iron absorption

Plant-based iron, or non-heme iron, is less bioavailable than heme iron from animal sources. However, its absorption can be significantly enhanced with certain dietary strategies.

Strategies for improved iron absorption

• Combine with Vitamin C: Consuming iron-rich seeds with vitamin C-rich foods is one of the most effective ways to boost non-heme iron absorption. Vitamin C, or ascorbic acid, helps convert non-heme iron into a more easily absorbable form. Examples include adding seeds to a smoothie with strawberries or a salad with citrus dressing.
• Reduce phytates: Seeds contain phytates, compounds that can inhibit mineral absorption. Soaking, sprouting, or fermenting seeds can help reduce their phytate content. Grinding seeds like flaxseeds before consumption also helps.
• Avoid tannins: Tannins, found in tea and coffee, can interfere with non-heme iron absorption. It is best to consume these beverages between meals rather than with them.
• Cook seeds: Roasting or cooking seeds can also help in breaking down some of the compounds that inhibit absorption, making the iron more accessible.
