Every day, a teenager should get the recommended amount of calcium. Therefore, choice B is right.
Why calcium is needed?
- Children between the ages of 9 and 18 are those most in need of calcium, as their bones and muscles need 1300 mg of calcium each day to grow and develop properly. Teenagers in this age range are still growing, thus they need the most calcium.
- A teenager should therefore be required to take the Recommended Dietary Allowance (RDA) of calcium each day in order to meet that adequate need.
- The contraction of muscles, the transmission of nerve signals, and blood clotting all depend on calcium, which is also crucial for bone strength.
- For men and women between the ages of 18 and 65, the current Recommended Dietary Allowance (RDA) for calcium is 1,000 milligrams (mg) per day.
A teenager should therefore have the Recommended Dietary Allowance (RDA) of calcium each day. So, option B is the correct answer.
