Title: The 6 Essential Nutrients Why you need them, and what they do for the body


1
The 6 Essential NutrientsWhy you need them, and
what they do for the body
2
Nutrient
  • Is a chemical substance in food that helps
    maintain the body

3
Nutrients
  • Nutrient Functions
  • Deficiency Disease
  • Some nutrient supply energy
  • All nutrients help build cells and tissue
  • They regulate bodily processes, like breathing
  • NO single food supply all of the essential
    nutrients.
  • Happens when there is a failure to meet all of
    your nutrient needs.

4
The 6 Essential Nutrients
  1. Carbohydrates
  2. Fats
  3. Proteins
  4. Vitamins
  5. Minerals
  6. Water

5
Carbohydrates
  • Carbohydrates are the bodys chief source of
    energy.
  • Carbohydrates include
  • Starches
  • Sugars
  • Cellulose

6
Functions of Carbs
  • They furnish the body with energy
  • They help the body digest fat, properly
  • They make foods taste better
  • They allow the body to use protein for growth and
    maintenance instead of energy

7
Sources of Carbohydrates
  • Complex Carbohydrates
  • Simple Carbohydrates

8
Fats
  • Functions
  1. Also is an important energy source.
  2. Help to carry vitamins throughout the body
  3. They make food taste good and tender.
  4. Help you to feel fuller

9
Types of Fats
  • Saturated
  • Have no double bonds in their chemical structure.
    They have a full load of hydrogen atoms.
  • Meat and dairy products tend to be high in
    saturated fat.

10
Types of Fats (cont)
  • Unsaturated Fat
  • Has atleast one double bond between two carbon
    atoms in each molecule.
  • Fats from plants tend to be higher in unsaturated
    fat.

11
Types of Fats (cont)
  • Trans Fat
  • When oils are partially hydrogenated, some of the
    unsaturated fat in oil change their molecular
    shapes.
  • Makes it act like saturated fat in the body
  • Can often be found in processed foods made with
    partially hydrogenated vegetable oils.

12
Hydrogenation
  • Is the process of breaking the double carbon
    bonds in unsaturated fatty acids and adding
    hydrogen.
  • This process converts liquid oils into solid
    fats.
  • This process is done to improve the keeping
    quality. Oils turn rancid if they are exposed to
    air or stored for a long time.

13
Rancid
  • Describes a food oil in which the fatty acid
    molecules have combined with oxygen. This causes
    them to break down, and the oil spoils. It has an
    unpleasant smell and taste.

14
Emulsifier
  • Is a substance that can mix with water and fat.
  • Ex adding an egg yolk to oil and vinegar
    that will form a mixture that will not separate.
  • Mayonnaise

15
CholesterolIs a white waxy lipid made by the
body that is part of every cell.
  • HDL
  • LDL
  • Pick up cholesterol from around the body and
    through a process transfers back to the liver.
  • Good Cholesterol
  • Carries through the bloodstream to cells.
  • Bad Cholesterol

16
Plaque Build-up
17
Proteins
  • Proteins are chemical compounds found in every
    body cell.
  • They are made up of small amino acids.

18
Functions of Proteins
  • Provide amino acids, which your body needs for
    growth (formation of new tissue), maintenance,
    and repair.
  • They aid in the formation of enzymes, some
    hormones, and antibodies.
  • Also provide energy.

19
Vitamins
  • Vitamins are complex organic substances.
  • You need them in small amounts for normal growth,
    maintenance, and reproduction.
  • Your body cant produce all the vitamins it
    needs, so you should get them from nutritious
    diet.

20
Vitamins
  • Fat-Soluble
  • Water Soluble
  • Dissolve in fats
  • They are carried by the fats in foods and can be
    stored in fatty tissues of the body.
  • Over-time, can build up in the body to dangerous
    levels.
  • A, D, E, K
  • Dissolve in water
  • The body doesnt store them to any great extent.
  • Excess amounts are carried out of the body
    through urine.

21
Supplements
  • These are nutrient products added to the diet.
  • Come in tablet, capsule, liquid, or powder forms.
  • Dont have to take a vitamin supplement if you
    get enough in your diet.

22
Minerals
  • Make up 4 of your body weight.
  • They become part of your bones, tissues, and body
    fluids.
  • Minerals also help regulate body processes.

23
Water
  • The body must have water to function
  • People can live more they a month without food,
    but only a few days without water.
  • Between 50-75 of your body weight is water.

24
Functions of Water
  • Water aid in proper digestion and cell growth
  • All chemical reactions in the body rely on water
  • Water lubricates the joints and body cells
  • Water also aids in regulating body temperature

25
Water Requirements
  • Eight glasses of fluid per day
  • - meaning liquids and the food you eat
  • Some people need more water than others
  • -Those who live in hotter climates
  • - People suffering from a fever or diarrhea
