Question

It is important to understand where to find calcium in food, but there are a variety of factors that can interfere with the absorption of even the best sources of calcium. Which of these statements describes ways calcium bioavailability or absorption may be reduced? Select all that apply

a. consuming calcium sources high in lactose
b. eating a low-protein diet
c. choosing calcium sources high in oxalates, like spinach
d. consuming vitamin D with a calcium-containing food
e. consuming large amounts of calcium at one time

Answer 1

Absorbtion or bioavailability of calcium may be reduced by option b,c and option e.

b. eating a low-protein diet

c. choosing calcium sources high in oxalates, like spinach

e. consuming large amounts of calcium at one time

Step-by-step explanation:

• Absorbtion of calcium can be reduced by eating low protein diet because protein helps reduce the way our intestines absorp calcium in the body.

• Choosing calcium sources high in oxaletes, like spinach helps reduce the bioavailability or absorption of calcium because there is a high amount of oxalic acid in spinach. Oxalic acid form insoluble crystal salt which later goes off by binding with calcium.

• Absorption or bioavailability of calcium can also be reduced by consuming large amounts of calcium at a time because if enough calcium is consumed at once, the chances of calcium absorption becomes less.

Answer 2

The correct answers are:

b. eating a low-protein diet

c. choosing calcium sources high in oxalates, like spinach

e. consuming large amounts of calcium at one time.

Step-by-step explanation:

Finding calcium in food is very important especially when you are interested in the best source as the case may be. Spinach is one of the right source of calcium because spinach contain high oxalic acid which bind with calcium to form insoluble salt crystal which is eliminated.

The eating of low protein diet helps in the reduction of absorption of calcium in the body system.

Also, absorption can be reduced by consuming large amounts of calcium at one time since more intake of calcium leads to decrease in absorption.
