NUT 111B (FINAL-MINERALS) QUESTIONS AND
ANSWERS STUDY GUIDE!!
What are the broad function and roles of minerals? Answers :Cofactors Facilitate specific structures and metabolic functions
cellular signaling processes
supporting structures
What broad recommendations did the DGA make for minerals? Answers :Limit food high in sodium
Meet needs w/ nutrient dense foods and beverages
What were the DGAs nutrients of concern? Answers :Sodium (needs to be less that 2300)
Underconsumption of calcium and potassium
Due to nutrients of concerns for sodium, what changes did we see on the nutrient facts label? Answers :Now we have sodium, calcium, iron and potassium added onto the label
What is the most abundant mineral in the body? Answers :Calcium (40% of total minerals)
1.5% of total body mass
What are the functions of calcium? Answers :Bine mineralization cell signaling
blood clotting
nerve transmission
What does calcium intake look like in the US? Answers :30% men 60% women (19+) dont meet needs
When is adequate intake of Ca and vit D most essential? Answers :During peak bone mass (19-30) and bone remodeling (post menopausal)
What are food sources of calcium? Answers :Dairy (rich and absorbable)
Certain vegetables and grains
In what food sources does calcium have low bioavailability? Answers :high in oxalic acid (ie: spinach)
high in phytic acid (ie: raw beans)
How do Ca supplements compare to food intake of Ca? Answers :Similar efficiency as milk BUT best absorbed when taken in doses of <500mg
Phytates also reduced the absorption of what other minerals? Answers :Fe and Zn
Although plant sources of Ca tend to have phytic acid, what does this not imply?
