Study Notes
Definition of Terms
- Nutrition studies the relationship between food and health.
- Diet refers to the total food consumed by an individual.
- Malnutrition includes deficiencies or excesses in essential nutrients.
- Digestion involves breaking down food into nutrients; absorption is the process of these nutrients entering circulation.
- Metabolism comprises the chemical changes for using nutrients in the body.
Digestion Types
- Mechanical digestion involves chewing, stomach churning, and peristalsis in intestines.
- Chemical digestion utilizes enzymes to convert food into simpler forms for absorption.
Nutrients and Their Importance
- Proteins, carbohydrates, and fats are energy sources.
- Vitamins and minerals, along with protein and water, are critical for building tissues and regulating bodily functions.
Oral Health and Nutrition
- Teeth consist of a protein matrix mineralized with collagen, necessitating vitamin C, calcium, and phosphorus, which depend on vitamins D and A.
- Malnutrition may lead to poor oral health, creating a cycle where poor oral health can exacerbate malnutrition.
Effects of Nutritional Deficiencies on Oral Health
- Nutritional deficiencies can hinder tooth development and contribute to dental caries.
- Specific conditions linked to nutritional deficits include glossitis, angular cheilitis, burning-mouth syndrome, cheilosis, scarlet tongue, noma, and oral cancer.
Dental Caries and Prevention
- Understanding the decay process is essential for prevention strategies.
- Fluoride plays a crucial role in preventing dental caries, including recommendations for supplementation.
- Foods categorized as cariogenic promote tooth decay, while cariostatic foods help protect against it.
Additional Factors
- Periodontal disease, tooth loss, and compromised nutritional well-being are interrelated.
- Interventions for tooth loss include the use of dentures and dietary adjustments.
Digestive System Overview
- The digestive system comprises various components facilitating digestion, absorption, and metabolism.
- Mechanical and chemical digestion occurs in distinct areas of the digestive tract, including the stomach and small intestine.
Importance of Oral Cavity
- The oral cavity is pivotal for digestion and nutrient absorption, influencing overall health and nutrition.
