  • Today
  • Lifestyle or Non-Communicable diseases
  • Nutrition Diet
  • Sedentary
  • Smoking, Alcohol
  • Back Then
  • Infectious or Communicable Diseases
  • Environmental Conditions

4
Life Expectancy
  • It would be the first time in the modern era we
    would actually see one generation experiencing a
    shorter life span than the previous generation."
  • The drop will occur when the current generation
    of obese and overweight adults reaches old age,
    and will worsen when obese and overweight
    children hit middle age.

McDonald's to Offer Nutrition Labels
15
Does the typical American utilize/understand
the Dietary Guidelines?
16
Starting Simple Recommendations
  • Where should your calories come from

17
Calories(Unit of Energy)
  • 1,600 calories is about right for many sedentary
    women and some older adults.
  • 2,200 calories is about right for most children,
    teenage girls, active women, and many sedentary
    men. Women who are pregnant or breastfeeding may
    need somewhat more.
  • 2,800 calories is about right for teenage boys,
    many active men, and some very active women.

18
The Basics.

19
Practical vs. Technical
  • Should you know
  • Fat grams
  • Sodium
  • Protein
  • Calories
  • Etc.
  • Per day?

20
The Key to Nutrition
  • Nutrient Density
  • High Nutrients per Caloric Content
  • VERSUS Empty Calories
  • The Key to proper nutrition is
  • Variety
  • Balance
  • Moderation (What does this mean?)

21
There are no good foods or bad foods
  • Foods are not good nor bad
  • Moderation and variety are key to enjoying all
    foods
  • Anytime foods
  • Sometimes foods
  • Seldom foods
  • Too many seldom foods and few anytime foods a
    bad diet

22
10 Tips for Healthy Eating
  • Eat a variety of nutrient-rich foods
  • Enjoy plenty of whole grains, fruits and
    vegetables
  • Maintain a healthy weight
  • Eat moderate portions
  • Eat smaller regular meals vs. one or two large
    meals.
  • Reduce, don't eliminate certain foods
  • Know your diet pitfalls.
  • Make changes gradually.
  • Remember, foods are not good or bad.

23
Pyramids Guide Our Choices
24
  • Understanding proper portion sizes is an
    important part of maintaining healthy nutrition.
    But many of us really dont know how big our
    portions should be.

Discover your own Snack Food Personality Profile
  • Pick Your Favorite Snack
  • 1 4
  • 2 5
  • 3 6

27
  • (1) Potato chips "Potato chip lovers are
    successful, high achievers who enjoy the rewards
    and trimmings of their successboth in business
    and in family life."
  • (2) Tortilla chips "Perfectionists in regards to
    their own actions and to the community at large,
    people who crave tortilla chips are humanitarians
    who are often distressed by the inequities and
    injustices of society."
  • (3) Snack crackers "Contemplative and
    thoughtful, people who prefer snack crackers base
    their decisions on logic rather than emotions."
  • (4) Pretzels "Lively and energetic, pretzel fans
    seek novelty and thrive in the world of abstract
    concepts. They often lose interest in mundane,
    day-to-day routines."
  • (5) Cheese curls "Formal, conscientious and
    always proper, the cheese curl lover can be
    described with one wordintegrity. They will
    always maintain moral high ground with their
    family, work and romantic partners."
  • (6) Meat snacks "Gregarious and social, those
    who reach for a savory bag of pork rinds or crave
    beef jerky and other meat snacks are often the
    life of the party. They are loyal and true
    friends who can always be trusted.
  • Did you notice that with this test everyone is a
    winner? Thats because the research for this
    personality test was "conducted on behalf of the
    Snack Food Association and the National Potato
    Promotion Board."

28
Essential Nutrients
  • Needed by the body must be present in the diet
  • Nonessential- your body can manufacture from
    other nutrients in the diet
  • Requirements depend on age, sex, growth status,
    body size, genetics
  • Requirements influenced by conditions like
    pregnancy, breastfeeding, illnesses, drug use,
    and others

29
THE BASICS. .
  • Nutrients Define
  • Substances in food that
  • Build and repair cells.
  • Regulate body processes.
  • Provide energy.
  • Nutrients that have Calories
  • Proteins 1 Gram 4 calories
  • Carbohydrates 1 Gram 4 calories
  • Fats 1 Gram 9 calories

30
The six Classifications of Nutrients
  • Vitamins
  • Minerals
  • Water
  • Protein
  • Carbohydrates
  • Fats

Starches
Cellulose
31
Sources of Energy in the Diet
32
Carbohydrates-4 cal/g
  • Are the bodys main source of energy (FUNCTION).
  • Supply fiber, and aid in digestion of fat.
  • Are broken down into sugars, starches and fiber.

33
Complex CarbohydratesSlow-Burning
  • Are starches.
  • Provide vitamins, minerals and fiber as well as
    carbohydrates.
  • Include dry beans, starchy vegetables like
    potatoes, corn, and peas rice, pasta, oatmeal
    bread and cereal.

34
Refined Carbs (Fast Burning)
  • The calorie content of refined white flour
    actually increases about 10 because of
    everything else that has been taken out.
  • An average of 66 of the B vitamins have been
    removed.
  • An average of 70 of all minerals have been
    removed.
  • 79 of the fiber has been removed.
  • An average of 19 of the protein has been
    removed.

35
What is the glycemic index?
Glycemic Index (GI)
A scale that ranks carbohydrates by how much they
raise blood glucose levels compared to a
reference food.
  • Low 0 55
  • Moderate 56 69
  • High 70 or more

43
Protein-4 cal/g
  • 2 major functions (working proteins structural)
  • Working-enzymes, antibodies, hormones, O carriers
  • Structural-tendons, ligaments, core of bone/teeth
  • Supplies energy when there is not enough fat or
    carbohydrate for the body to use.

44
Protein
  • Composed of amino acids (building blocks).
  • There are 22 amino acids
  • 9 of which the body cannot manufacture
    (ESSENTIAL),
  • and 13 which the body can produce
    (NON-ESSENTIAL).

45
Protein
  • Complete proteins contain all 9 essential amino
    acids. They are foods which come from animals.
  • This includes steak,pork,chicken, turkey, fish,
    eggs and dairy products.

46
Protein
  • Incomplete proteins lack one or more of the
    essential amino acids.
  • This includes pinto beans, kidney beans,split
    peas, lentils, rice, corn tortillas, peanut
    butter, and nuts.

47

48
Protein Recommendations
  • The RDA for protein is 0.8 grams per kilogram of
    body weight per day (.364 gr/lb/bw/d).1
  • That's about 9 grams of protein for every 20
    pounds
  • RDA levels may be inadequate and may impede
    recovery or limit muscle growth for athletes?
  • Endurance athletes 1.2 to 1.4 grams per kg b/w.
  • Strength and power athletes 1.4 to 1.8 grams per
    kilogram of body weight per day.

49
Fats, Cooking Oils and Fatty Acids
  • Fat should account for 30 or less of the
    calories consumed daily
  • Saturated fats accounting for no more than 10 of
    the total fat intake.
  • Function
  • Maintain body temperature
  • Protect body tissues and organs
  • Plays an essential role in carrying the four
    fat-soluble vitamins A, D, E, and K.
  • Excess calories from protein and carbohydrates
    are converted to and stored as fat. Even if you
    are eating mostly "fat free" foods, excess
    consumption will result in additional body fat.

50
Fats-9 cal/g
51
Animal vs. Plant Foods and Heart Disease in
Pictures--
  • .Saturated
  • Unsaturated

52
Trans Fat
  • Trans fat is a type of processed fat that does
    not occur in nature
  • Also called hydrogenated or partially
    hydrogenated fat/oil
  • Used in baked goods like doughnuts, breads,
    crackers, potato chips, cookies and many other
    processed food products like margarine and salad
    dressings.
  • Research suggests a correlation between diets
    high in trans fats and diseases like
    atherosclerosis and coronary heart disease

53
Fat the Body
  • The fats can be stored in any cell in the body
    but are mostly stored beneath our skin.
  • These fat tissues are called adipose tissue where
    the fat cells join together, depositing under our
    skin to make us fat.
  • In women, the adipose tissue is mostly found in
    the hips, buttocks, and thighs
  • while in men, it is found in the abdomen causing
    big bellies.

54
Vitamins
  • Major Functions
  • Convert fat and carbohydrate into energy.
  • Work as catalysts for chemical processes in the
    body- jump start reactions.
  • Assist in the formation of tissue and bone.

55
Vitamins
  • Water soluble vitamins are carried in water and
    cannot be stored in your body.
  • Excess water soluble vitamins are disposed of in
    the urine.
  • Fat Soluble vitamins are carried in fat and can
    be stored in your body.
  • It is possible to overdose on fat soluble
    vitamins.

Minerals
  • Minerals act as
  • catalysts for many biological reactions within
    the body (function)
  • 1-muscle response
  • 2-the transmission of messages through the
    nervous system
  • 3-the production of hormones
  • 4-digestion, and the utilization of nutrients in
    foods.
