Question 3

__________ is the most abundant mineral on Earth, and it is the most abundant trace element in the human body. It is a mineral your body needs in order to grow, develop, and support many functions. For example, this mineral is part of your hemoglobin, which is a protein that carries oxygen from your lungs throughout your body. It helps your muscles store and use oxygen. Your body also needs it to make some of your hormones and connective tissues. It is also part of many other proteins and enzymes in your body.

Answer 3

Iron (Fe)

Question 4

__________ is a trace mineral that is unique in that almost all of it that you consume is absorbed by your body. Unlike iron and zinc, the absorption of this nutrient is not controlled by your small intestine. Once it is absorbed, it is stored in different tissues in your body (such as your bones, muscles, liver, and, kidneys). If you consume too much, the excess will be excreted by your kidneys in urine. This trace mineral is important for regulating the hormones in your thyroid gland, and it has been linked to lower risks of developing cancers of the lungs, colon, and prostate because of the antioxidants it has.

Answer 4

Selenium (Se)

Question 5

__________ is a trace mineral that is either part of the enzymes in your body or activates many of the enzymes in your body.
