PUBLIC HEALTH NUTRITION
Nutrients
1. Carbohydrates
2. Proteins
3. Lipids
4. Vitamins
5. Minerals
6. Water – functions:
a. Solvent
b. A lubricant
c. Transport medium
d. Regulate body temperature
7. Macronutrients – carbohydrates, proteins, lipids required in grams, kilograms
8. Micronutrients – vitamins and minerals needed in micrograms or milligrams
9. Energy needed for
a. Basic body functions/basal metabolism (60 – 75% total energy requirement)
b. Physical activity (15 – 30%)
c. Processing consumed food (5 – 10%)
10. Energy balance: the balance between energy consumed and utilised.
11. Positive energy balance: occurs when energy input is more than expended. Leads to weight gain.
12. Negative energy balance occurs when energy intake is less than energy expended. Results in utilization of energy stores and weight loss.
13. Nutrients are chemical substances in food that provide energy, structure (growth) and regulate body processes. maintain the biological processes, growth and reproduction
14. Nutrients: part of food the body uses to build tissue, produce energy and keep healthy
15. Essential Nutrients are nutrients that must be provided in the diet because the body cannot synthesize them or cannot make them in enough quantities as required to satisfy the body’s needs.
16. Nutrition:
a. It is the study of foods and how our bodies use them
b. Is concerned with how food is produced, processed, handled, sold, shared, and eaten as well as the of digestion, absorption and utilization of food in the body.
17. Other substances in food – anti-nutrients, food additives, contaminants, harmless microbes (yeast, bacteria)
18. Balanced diet: a diet that contains all the essential nutrients in their right amounts necessary for optimal body function.
19. Importance of good nutrition
a. Stronger immune system
b. Less illness
c. Better health
d. Children learn better
e. Stronger people
f. Stronger and healthy people
g. More productive
