Lecture 1 - Nutrition and Oral Health (Introduction) Flashcards
What is the definition of nutrition?
study of the role of nutrients in growth, development, and repair of our body tissue
What is the definition of diet?
daily intake of food with different types of nutrients which affect our health
What is the definition of health?
not only the freedom from disease but also freedom from conditions of mental disturbances, emotional distress, and spiritual discontent and social maladjustment, whereas maximum health is well-being or wellness.
What is the definition of ORAL HEALTH?
improving quality of life through oral hygiene and healthy eating, which can reduce the risks of oral disease. There is a bidirectional relationship between diet and oral health. A healthy/ balanced diet is associated with good periodontal health and teeth, as well as good quality of saliva
Foods supply what kind of nutrients?
Essential nutrients
Our body makes what kind of nutrients?
Non-essential nutrients
What are the 6 classes of nutrients?
- carbs
- fats
- proteins
- vitamins
- minerals
- water
What are the macronutrients?
Carbohydrates, fats, and protein. Organic nutrients that yield energy (and support metabolic energy)
What are micronutrients?
water, vitamins (organic molecules), and minerals (inorganic molecules). They dont yield energy but support metabolic processes.
does alcohol yield energy in the body? Is it a nutrient?
Yes. however is not considered a nutrient because it does not support metabolic processes.
What unit do we use to measure the amount of energy produced from nutrients?
Kilocalories (Kcal)
What is the energy yield from carbs, protein, fats, and alcohol?
fats 9kcal/g, carbs and proteins 4 kcal/g. alcohol 7kcal/g
What is another name for nutritional standards?
Dietary Reference Intakes (DRI)
What are the 6 sets of DRI values?
- Estimated average energy requirement
- recommended dietary allowance
- adequate intake
- estimated energy requirement
- tolerable upper intake level
- acceptable micronutrient distribution ranges
What is the recommended AMDR (acceptable micronutrient distribution ranges) for the 3 energy yielding nutrients?
45-65% from carbohydrates
20-35% from fat
10-35% from proteins
