Study Notes
Anorexia Nervosa
- Primarily characterized by an intense fear of gaining weight and a distorted body image, leading to extreme dieting or starvation.
Functions of Water
- Water is essential for regulating body temperature, transporting nutrients, and facilitating cellular processes.
- Not a function of water: providing energy to the body.
Roles of Nutrients
- Nutrients are vital for maintaining health by providing energy, supporting growth, and enabling metabolic processes.
- Essential nutrients include carbohydrates, proteins, fats, vitamins, and minerals.
Carbohydrates
- Carbohydrates are primarily classified as a key energy source for the body.
- Main characteristic includes their composition of carbon, hydrogen, and oxygen.
Sugars
- A double sugar, or disaccharide, includes sucrose (table sugar) and lactose (milk sugar).
- Complex carbohydrates consist of multiple sugar units and include starch and fiber.
Proteins
- Proteins serve as building blocks for tissues, play a crucial role in enzyme and hormone production, and support immune function.
- Essential amino acids are required through diet, as the body cannot produce them.
Summary of Water Function
- Main function of water includes acting as a solvent for biochemical reactions and helping in waste removal through urine.
Additional Characteristics
- Carbohydrates, when complex, are composed of longer chains of sugar molecules, providing sustained energy.
- Anorexia nervosa can lead to severe health issues, including malnutrition and organ failure, due to lack of essential nutrients.
