In addition to iron, shellfish also boast a range of other essential nutrients, such as omega-3 fatty acids, selenium, and vitamin B12. These nutrients contribute to overall health and can be particularly beneficial for older adults, supporting cognitive function and cardiovascular health.
Spinach
Spinach is a versatile leafy green vegetable that is not only rich in iron but also packed with other essential vitamins and minerals. It is also a good source of vitamin C, which significantly enhances the absorption of iron in the body. This combination makes spinach an excellent choice for older adults looking to boost their iron intake.
Incorporating spinach into meals and salads can provide a nutrient-dense and flavorful addition to the diet. Whether cooked or eaten raw, spinach offers a convenient way to increase iron levels while enjoying a variety of delicious dishes.
Organ Meats
Organ meats, such as beef liver, are known for their high iron content and bioavailability. A 3.5-ounce (100-gram) serving of beef liver can provide 6.5 mg of iron, representing 36% of the Daily Value (DV). Organ meats are not only rich in iron but also contain protein, B vitamins, copper, and selenium, making them a nutrient-dense choice for older adults.
