Question 1

Why do older adults require more vitamin D?

Accepted Answer

To support bone health

Answer

Older adults require more vitamin D primarily to support bone health. As people age, their skin's ability to synthesize vitamin D from sunlight decreases, and their kidneys are less efficient at converting it to its active form. Adequate vitamin D is crucial for calcium absorption and bone mineralization, helping to prevent osteoporosis and maintain skeletal integrity.

Question 2

Which supplement may be recommended during pregnancy?

Accepted Answer

Folic acid

Answer

Folic acid supplementation is strongly recommended before and during early pregnancy to help prevent neural tube defects (NTDs) in the developing fetus, such as spina bifida. Folic acid plays a critical role in cell division and DNA synthesis, which are vital for rapid growth and development during pregnancy. This preventative measure significantly reduces the risk of serious birth defects.

Question 3

What nutrient is crucial for athletes' muscle recovery?

Accepted Answer

Protein

Answer

Protein is crucial for athletes' muscle recovery because it provides the essential amino acids needed to repair and rebuild muscle tissue damaged during intense exercise. Consuming adequate protein after workouts helps facilitate muscle protein synthesis, reduce soreness, and support muscle growth and adaptation. This is vital for performance and preventing injury.

Question 4

What is a common nutrition concern for vegans?

Accepted Answer

Vitamin B12

Answer

Vitamin B12 is a common nutrition concern for vegans because it is primarily found in animal products. Without supplementation or fortified foods, vegans are at risk of deficiency, which can lead to serious neurological problems and anemia. Therefore, careful planning and supplementation are essential for vegans to meet their B12 requirements.

Question 5

Which population benefits from iron supplementation most often?

Accepted Answer

Women of childbearing age

Answer

Women of childbearing age most often benefit from iron supplementation due to menstrual blood loss and increased iron needs during pregnancy. Iron is vital for red blood cell production and oxygen transport throughout the body. Supplementation is often necessary to prevent iron deficiency anemia, which can cause fatigue and impaired cognitive function in this population.
