Difficulty: EasyHealth, Nutrition, and Disease

Vitamin D plays a critical role in human nutrition by facilitating the absorption of calcium in the digestive tract to support bone health.

Answer: Answer

Answer

The statement is true because vitamin D is biologically required for the intestinal absorption of calcium.
Vitamin D promotes the synthesis of calcium-binding proteins in intestinal epithelial cells, enabling efficient dietary calcium absorption and supporting proper skeletal mineralization.

Step-by-Step Solution

1
Identify the primary physiological function of vitamin D in human nutrition.
Vitamin D regulates calcium and phosphate homeostasis by promoting their absorption in the small intestine.
Adequate calcium cannot be efficiently absorbed from dietary sources without sufficient active vitamin D.
2
Evaluate the accuracy of the provided statement against biological principles.
The statement correctly connects vitamin D with calcium absorption and skeletal health.
This confirms that the evaluated claim is true.
