Essential nutrients for optimal growth and good health

Essential Nutrients for Optimal Growth and Good Health


Essential nutrients en

Essential Nutrients (EN)

Essential Nutrients

Required for health; obtained from our diet

Body cannot make enough, or any of the nutrient

  • Non Essential Nutrients

    • Required for health

    • Body can make enough to meet our needs

    • e.g. creatine, lecithin, cholesterol etc.


Essential nutrients n 6

Essential Nutrients (N=6)

Carbohydrateorganic (o), energy (nrg)

Lipid (fats/oils)o, nrg

Protein o, nrg, contains nitrogen

non-preferred nrg source

Vitamins o, not an nrg source

Minerals inorganic (i), not an nrg source

Water major component body wt. most acutely needed EN

Note: organic(o) = contains carbon


Evaluating dietary quality

Evaluating Dietary Quality

  • Define these terms

    • Nutrient Dense (ND) - many nutrients/gram of food

    • Calorie Dense (CD) - many calories/gram of food

    • Empty Calorie (EC) - very few nutrients/calorie of food


Caloric density calories wt of food

Caloric Density: calories/wt of food

90 calories/lb

1200 calories/lb

And that is without cream cheese!

Evaluating diet quality

Evaluating Diet Quality

  • Using ND, CD and EC, describe the type of diet you advise to reach each goal.

  • Be ready to explain your choice.

    • A healthy college student trying to lose 10 pounds

    • A competitive athlete desiring weight gain

    • A healthy 5 year old child

    • Someone recovering from burn/injury/surgery

    • A healthy elderly woman who uses a walker


Energy nutrients

Energy Nutrients

Carbohydrate (4 calories/g)

Lipid (9)

Protein (4)

Reminder:

Alcohol provides

energy but

is NOT an EN


Energy nrg nutrients

Energy (nrg) Nutrients

NRG nutrients are:

organic

contain carbon

can be burned (oxidized) to make ATP**

** ATP is the fuel cells use to do their work.

NRG nutrientsATP

(fuel from food) cellular(fuel for cells)

respiration

NRG nutrientsATP

(fuel from food) cellularWhat does the P stand for?

respiration Is it essential?


Cellular respiration equation

Cellular Respiration Equation

NRG nutrient + O2 H2O + CO2 + ATP + heat

  • Typically these reactions only happen in a special part of acell (mitochondria).

  • There is also a bit of ATP produced in other ways.


Respiration vs photosynthesis

Respiration vs. Photosynthesis

Cellular respiration (animal function)

nrg nutrient + O2 H2O + CO2 + ATP + heat

(C, P, L) (nrg)

Photosynthesis (green plant function)

solar nrg+ H2O + CO2 nrg nutrient* + O2

(*glucose, a type of carb)


Plants

Plants!!!!!

  • Ultimately all Calories are solar in origin

  • Green plants convert solar energy to nrg nutrients

  • Plants + helper organisms

    capture Nitrogen form we use

    (amino acids)

    Food security is intimately

    tied to the health of

    the environment!


Next class

NEXT CLASS

  • Please bring a food label to class......

    a food product you actually eat not candy or gum 

  • See website for lecture notes and handouts

  • Try a new veggie this weekend!!!


Partner up think and answer

Partner Up, Think and Answer!

  • What is the most vital component of food production?

  • Name the essential nutrients. Which give us energy?

  • Why is an orange more nutrient dense than OJ?

  • Which EN has the most Calories/gram?

  • Compare and contrast the substrates of cellular respiration and the products of photosynthesis.

  • What is the form of NRG the cell can use?
