Micronutrients

Vitamins and minerals essential for bodily functions in small amounts. Their deficiency can lead to severe health problems.

Importance of water

Water plays a crucial role in various bodily functions, including nutrient transport, waste removal, and temperature regulation. It accounts for a large percentage of our body weight.

Dehydration

The state of having insufficient water in the body, leading to various symptoms like fatigue, headaches, and decreased energy.

Recommended water intake

Recommended daily water intake is at least 8 glasses of 8 ounces each. However, individual needs may vary depending on factors like activity level and climate.

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.
