Study Notes
Micronutrients and Water
- Micronutrients (vitamins and minerals) are needed in small amounts for crucial bodily functions. Deficiency can cause serious health problems.
- Micronutrients help produce enzymes, hormones, and substances needed for growth and development.
- Water makes up 50-60% of body weight.
- Water carries nutrients to cells, lubricates joints, cushions organs, removes waste, and regulates temperature.
- Drinking throughout the day is better than waiting until feeling thirsty.
- Dehydration results from a lack of water, causing fatigue and headaches.
- Water loss occurs through sweating, illness, and sun exposure.
- Daily water intake should be at least 8 cups (8 oz each).
- 20% of daily water intake comes from food, especially fruits and vegetables.
- The body needs 30 vitamins and minerals, all from diet except Vitamin D (made from sunlight).
- Vitamins and minerals do not provide energy.
Vitamin Examples
- Vitamin A: Crucial for vision, immunity, and reproduction. Found in sweet potatoes, carrots, and spinach.
- Vitamin B: Releases energy from foods. Found in whole grains, bread, cereals, and milk.
- Vitamin C: Boosts the immune system, aids collagen production, wound healing, and tooth/bone formation. Found in oranges, kiwis, strawberries, and peppers.
- Vitamin D: Promotes calcium absorption for bone health. Obtained from sunlight, milk, salmon, tuna, and eggs.
Mineral Examples
- Minerals don't provide energy, but maintain water balance (sodium, chloride, potassium).
- Calcium, phosphorus, and magnesium are essential for healthy bones.
Essential Minerals for Teens
- Calcium: Builds strong bones, found in dairy products.
- Iron: Binds oxygen for energy production, found in red meat, spinach, and apricots. Iron deficiency causes fatigue; girls need more iron due to menstrual loss.
- Fiber: Does not provide energy but aids in waste elimination and fat binding.
Micronutrients and Hydration for Teens
- Adequate water is critical for micronutrient absorption and function.
- Crucial micronutrients for teens include Calcium, Vitamin D, Iron, and Vitamin B12.
- Water helps digestion, temperature regulation, and nutrient transport.
- Dietary restrictions (vegetarian/vegan) may require special attention to micronutrient intake (especially Vitamin B12 and Iron).
- Poor diet choices and excessive sugary drinks contribute to micronutrient deficiencies and dehydration.
- Water helps dissolve micronutrients, making them more readily absorbed
- Water transports nutrients throughout the body.
