HUMAN NUTRITION

Detailed explanation-1: -Iron from food comes in two forms: heme and non-heme. Heme is found only in animal flesh like meat, poultry, and seafood. Non-heme iron is found in plant foods like whole grains, nuts, seeds, legumes, and leafy greens.

Detailed explanation-2: -Organ meats like liver and giblets are especially rich in iron. For example, 113 grams of chicken giblets has 6.1 mg of iron, making it an excellent source. Meanwhile, liver serves up an impressive amount of iron. One ounce of pork liver comes packed with 6.61 mg of iron, another excellent source.

Detailed explanation-3: -Gram per gram, vegetables often have a higher iron content than foods typically associated with high iron, such as meat and eggs. Though vegetables contain non-heme iron, which is less easily absorbed, they are also generally rich in vitamin C, which helps enhance iron absorption (1).
