Study Notes

Key Concepts in Nutrition

Nutrients: Chemical compounds in food providing energy, growth, maintenance, and regulation of body processes.
Six Classes of Nutrients: Includes carbohydrates, fats, proteins, vitamins, minerals, and water.
Phytochemicals: Non-nutrient compounds that promote health and combat chronic diseases.

Understanding Nutrition

Nutrition: The scientific study of how foods nourish the body and influence health.
Macronutrients: Energy-yielding nutrients (carbohydrates, lipids, proteins) needed in larger amounts.
Micronutrients: Vitamins and minerals essential for health, required in smaller quantities.

Essential Nutrients and Their Roles

Carbohydrates: Provide glucose, a major energy source.
Fats: Serve as a significant energy source; protect and cushion organs.
Proteins: Primarily support growth and maintenance of tissues; can also supply energy.
Vitamins and Minerals: Critical for metabolic functions.
Water: Vital for numerous bodily processes.

Professional Practices in Nutrition

Nutritional Genomics: Examines how food components affect gene expression and overall health.
Registered Dietitian (RD): Completion of a degree and supervised practice; passes a national examination.
Public Health Nutritionist: Degree holder in nutrition without RD credentials.
Licensed Dietitian: State-licensed professional in nutrition.

Health Statistics and Dietary Trends

Heart Disease: Leading cause of death in the U.S.
Obesity Rates: Approximately 65% of American adults are overweight or obese.
