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.
