Nutrition Chapter 1 questions with
answers
Processes of Nutrition is studied at four levels. What are they? ✅✅1. Nutritional
Genomics (genes and our body)
2. Cell & Molecular Nutrition (metabolism, molecular level)
3. Clinical Nutrition (lab discoveries & age/gender)
4. Community Nutrition (broad population, policy research)
Explain the Continuum of scientific investigation: ✅✅Genome --> Molecule --> Cell --
> Clinical --> Family --> Population
What are the 3 main functions of chemical compounds in food? ✅✅1. provide energy
2. help to grow
3. help to maintain and regulate body system
What are the six major classes of nutrients? ✅✅Macro: carbohydrates, proteins, fat
Micro: vitamins, minerals
Neither: water
How much do you need of both? ✅✅Macronutrients = need in small amounts
Micronutrients = need in small amounts
What functions do nutrients have? ✅✅1. organic compounds
2. have hydrogen and oxygen atoms
3. provide energy
How many kcal = 1 calorie? ✅✅1 kcal = 1 calorie
How many calories in carbohydrates, proteins, and fat? ✅✅carb = 4cal/g
prot = 4cal/g
fat = 9cal/g
What macronutrient does your body prefer to use for energy? and WHY? ✅✅* prefers
carbohydrates for energy BECAUSE
1. certain body parts can only use carbohydrates for energy - cannot use proteins
(example: RBC and brain)
2. carbohydrates are the only one that provide energy (it is not involved in growth,
maintenance, other processes)
What are micronutrients? Do they provide energy? Main function? ✅✅Vitamins and
minerals. No calories.
Essential for metabolism, convert macronutrients into energy, essential for growth and
maintenance.
