Question

Animal sources of iron are ______ bioavailable than plant sources of iron.

Answer 1

The correct answer filling term would be - "more".

Explanation:

Bioavailable is a term in pharmacology which means that how much some nutrient or drug is easily absorbed by the body. Iron is a nutrient that is essential for the body for several cellular functions. Iron can be divided into two types heme and non-heme. Heme is the form of iron that is easily absorbed by the body and only found in animal-based food such as meat, egg or poultry products.

Plant sources of iron are non-heme and not well absorbed by the body, this is one of the reasons that makes animal source iron more bioavailable than plant sources of iron.

Thus, the correct answer is - "more".

Answer 2

Animal sources of iron are more bio-available than plant sources of iron. Bioavailability of dietary iron is the most important of anaemia. Haem iron found in animal sources such as meat, poultry and fish, has greater bioavailability than does non-haem found in cereals, pulses, fruits and vegetables. The bioavailoability of iron is approximately 14% to 18% from mixed diets that include substantial amounts of meat, seafood, and vitamin C and 5% to 12% from vegetarian diets.
