Study Notes
Minerals in Home Economics
- Minerals are essential nutrients required by the body.
- Some minerals are needed in large amounts (macro minerals) and others only in small amounts (trace minerals).
- Macro minerals include calcium, phosphorus, potassium, and sodium.
- Trace minerals include iron, zinc, and iodine.
- Calcium is vital for strong bones and teeth.
- Approximately 99% of the body's calcium is found in bones and teeth.
- The remaining 1% is important for blood clotting, nerve and muscle function.
- Calcium aids in the formation of strong bones and teeth.
- It also helps with blood clotting and muscle contractions.
Sources and Deficiencies of Calcium
- Good sources of calcium include milk, almonds, cheese, and leafy green vegetables like spinach.
- A lack of calcium can increase the risk of bone diseases (osteomalacia and osteoporosis), and dental problems.
- It can also cause slowed blood clotting and muscle spasms or cramps.
Recommended Dietary Allowances (RDAs)
- RDA for calcium varies depending on age and life stage.
- Children typically require 800 mg, teens need 1200 mg, and adults need 800 mg.
- Pregnant women need 1200 mg of calcium daily.
