    Study Notes

    Definition of Nutrition

    • Nutrition refers to the intake of food necessary for meeting the body’s needs for survival.
    • Nutrients are essential substances found in food and beverages critical for bodily functions.

    Components of Nutrition

    • Food consists of macronutrients (carbohydrates, fats, proteins) and micronutrients (vitamins, minerals).
    • Macronutrients provide energy:
      • Carbohydrates: 4 calories/gram
      • Fats: 9 calories/gram
      • Proteins: 4 calories/gram
    • Water is classified as a macronutrient but does not provide energy.

    Caloric Intake

    • Daily calorie needs vary based on age, sex, and physical activity:
      • Women: 1,600 to 2,400 calories
      • Men: 2,000 to 3,000 calories
    • Understanding calories is essential for assessing food intake and energy needs.

    History of Nutrition

    • Significant advancements occurred in nutrition science during the 20th century, including the identification of essential vitamins and minerals.
    • 1906: Pure Food and Drugs Act initiated federal regulation of foods, overseen by the FDA.
    • 1938: Food, Drug, and Cosmetic Act introduced enhanced food labeling requirements.
    • 1977: Dietary Goals for the United States aimed to improve diet quality to reduce heart disease.
    • 1990: Nutrition Labeling and Education Act mandated clear nutritional labeling on food packaging.

    Nutrition and Health

    • Hippocrates' philosophy: "Let food be thy medicine" reflects the ancient acknowledgment of nutrition’s role in health.
    • WHO (1948) defined health as holistic well-being, emphasizing nutrition’s integral role.

    Nutritional Assessment

    • Body Mass Index (BMI) measures weight status based on height and weight, classifying individuals into categories:
      • Underweight: < 18.5
      • Healthy weight: 18.5 to < 25
      • Overweight: 25 to < 30
      • Obesity: 30 and above
    • Waist-to-hip ratio (WHR) assesses body composition, indicating risk for health conditions associated with body fat distribution.

    Health Considerations

    • Recent research has challenged BMI’s effectiveness as a sole obesity indicator, especially for diverse populations.
    • AMA encourages using BMI alongside other tools for a comprehensive assessment of obesity.

    Health Promotion

    • Healthy People 2030 aims to improve health and well-being through recommended dietary practices to reduce the risk of long-term diseases.
