Study Notes
Functions of Water
- Essential for regulating body temperature, lubricating joints, and acting as a universal solvent.
- Water is indispensable for various physiological functions.
Minerals and Health
- Calcium and phosphorus form the structural components of bones and teeth.
- Iron is associated with oxygen transport but is not classified as a major mineral.
Iron Functions and Absorption
- Iron plays key roles in oxygen transport, enzymatic activity, and preventing anemia, but does not act as a buffer.
- Nonheme iron, found in plant foods, requires vitamin C for efficient absorption.
Dietary Sources
- Hard water contains high levels of calcium and magnesium; soft water typically has elevated sodium levels.
- Rich dietary sources of zinc include pumpkin seeds, yogurt, lamb, and beef.
Osteoporosis and Risk Factors
- Osteoporosis risk factors include older age, low body weight, but not specifically African American heritage.
Nutritional Needs and Deficiencies
- Iodine deficiency during pregnancy can lead to cretinism in newborns.
- Signs of zinc deficiency include cracked nails, ingrown hairs, and impaired immune function.
Importance of Specific Nutrients
- Calcium is the most abundant mineral in the body, vital for bone health.
- Chloride contributes to the stomach's acidity, aiding digestion.
Iron Forms
- Heme iron is found in animal products; nonheme is from plant sources.
- Most iron in the body is found in hemoglobin and myoglobin proteins.
Water Regulation
- Sodium regulates blood volume and pressure by attracting water, demonstrating the link between electrolytes and fluid balance.
Inhibitors of Iron Absorption
- Vitamin C enhances iron absorption; however, tea, coffee, calcium, and phosphorus inhibit it.
