Study Notes
Calcium and Bone Health
- Calcium is essential for bone health, primarily in the forms of calcium phosphate and calcium carbonate.
- The body cannot synthesize calcium; it must be obtained from dietary sources.
Importance of Vitamin D
- Vitamin D is crucial for calcium absorption in the small intestine.
- It also contributes to bone remodeling, although its exact role in this process is not fully understood.
Dietary Sources of Calcium
- Major sources of calcium include:
- Dairy products (e.g., milk, cheese, yogurt).
- Green leafy vegetables (e.g., kale, spinach).
- Broccoli.
- Fish with soft bones, such as intact salmon and canned sardines.
- Nuts, beans, seeds, and shellfish provide calcium in lesser amounts.
Sources of Vitamin D
- Natural food sources of vitamin D are limited to certain items:
- Fatty fish like salmon and tuna.
- Fortified foods (such as milk and cereals).
- The body can produce vitamin D through skin exposure to sunlight.
Vitamin D Deficiency
- Many individuals, particularly those with darker skin and those living in northern latitudes, may experience vitamin D deficiency due to insufficient sunlight exposure.
- In cases of deficiency, healthcare providers can prescribe vitamin D supplements.
