you eat. CO 2. Analyze the information contained
on food labels.

Choosing Food Wisely
  • You eat for several reasons to meet you
    nutritional needs, to satisfy your appetite, and
    to supply your body with energy. Hunger is a
    feeling of physical discomfort that is caused by
    your bodys need for nutrients. Appetite is a
    desire for food that is based on emotional and
    other factors rather than nutritional need for
    food that is based on emotional and other factors
    rather than nutritional need.
  • Your bodys nutritional needs are related to your
    basal metabolic rate. Basal metabolic rate (BMR)
    is the rate at which you use energy when your
    body is at rest. Your level of activity also
    affects your calorie.

4
Factors influencing food choices
  • Your food choices are based on many factors.
    These factors include personal preferences,
    cultural background, time and convenience,
    friends, and the media.
  • When choosing foods, it is important to read
    and evaluate the information on the food label.
    The information includes nutrition facts,
    nutrient and health claims, Daily Values, and
    freshness date. The United States Food and Drug
    Administration (FDA) requires that food labels
    list specific nutrition facts about a food. These
    facts include calorie and nutrient content and
    health claims that can be printed on a food
    label.

5
Continued
  • Nutritionists have developed a tool called
    Daily Values to help people make good food
    choices. Daily Values are recommendations that
    specify the amounts of certain nutrients that the
    average person should obtain each year. Food
    labels list the percent Daily Values for each
    nutrient in the food. Labels on prepared foods
    also include open dates that give consumers an
    idea of how long the food will be fresh and safe
    to eat. Three kinds of dates are the sell-by
    date, the best-if-used-by date, and the
    do-not-use-after date.

    for you?

Safely Managing Your Weight
  • A persons weight is determined by various
    factors, including heredity, level of activity,
    and body composition. Based on your family
    history, you may have a natural tendency toward a
    certain weight. Your activity level influences
    your weight the more active you are, the more
    calories you burn. Body composition is a measure
    of how much body fat you have, as compared to
    muscle and bone. Sex and age affect your body
    composition.
  • One simple way to assess whether your weight
    falls within a healthy range is to calculate your
    body mass index. Body mass index (BMI) is a ratio
    of your weight to your height.
  • The number of people in the United States who
    are overweight is increasing. Being overweight
    can lead to serious health problems, including
    heart disease and diabetes. Overweight describes
    a person who is heavier than the standard for the
    persons height. Obesity (oh bee sih tee) refers
    specifically to adults who have a BMI of 30 of
    higher.

14
Health Risks
  • The health risks associated with being
    overweight include high blood pressure, excess
    cholesterol in the blood, excess glucose in the
    blood, heart disease, stroke, and certain
    cancers. Managing your weight can help prevent
    these health risks.
  • Underweight describe a person who is lighter
    than the standard for the persons height. Being
    underweight can be linked to health problems such
    as anemia, heart irregularities, and trouble
    regulating body temperature.
  • Sensible weight management involves avoiding
    dangerous diet plans, choosing nutritionally
    balanced meals and snacks, and getting regular
    exercise. Fad diets, diet aids, and fasting are
    unsafe ways to lose of gain weight. A fad diet is
    a popular diet that may help a person lose of
    gain weight without proper regard for nutrition
    and other health issues. Fad diets can place the
    dieters health at risk.

15
Weight Loss Strategies
  • Some strategies for safe and sensible weight
    loss include recognizing your eating patterns,
    planning helpful weight-loss strategies, and
    exercise. Strategies for sensible and safe weight
    gain include increasing your calorie intake by
    choosing nutrient-dense foods and exercising
    regularly.

16
Warm Up
  • Health Stats What health trend do these
    statistics reveal?
  • Writing What changes might help reverse this
    trend? How successful do you think the changes
    would be?

    teens facing different weight management issues.
    For each person, make a recommendation about what
    the person should do in the situation described.
    Be sure to consider all of the factors that could
    influence the persons decision before making
    your recommendation.

    lose some weight. But Joshs friends always go
    out to fast food restaurants. How can Josh eat
    healthy when out with friends?

with food sensitivities, and athletes can meet
their nutritional needs. LO 3. Complete a list
of health concerns and give diet tips for
diabetics, vegetarians, people with food

Warm Up
  • Dear Advice Line,
  • Writing Write a response to this teen to help
    solve the problem.

27
Nutrition for Individual Needs
  • Diabetes is a disease with dietary requirements
    that can help people manage their condition. Poor
    nutritional habits and being overweight increases
    the risk of type 2 diabetes. Type 2 diabetes is a
    condition in which the blood contains high levels
    of glucose. Eating balanced meals on a regular
    schedule, monitoring carbohydrate intake, and
    controlling weight are important for managing
    diabetes.
  • A vegetarian is a person who does not eat meat.
    A vegan is a vegetarian who does not eat only
    food that comes from an animal source. Because
    vegetarians exclude certain foods from their
    diets, they need to plan their food choices
    carefully to avoid potential health risks.
    Benefits of a vegetarian diet can include a lower
    BMI and a lower risk of heart disease and type 2
    diabetes. Vegetarians must plan their diets
    carefully to make sure that they get all the
    amino acids their bodies need to build proteins
    as well as adequate supplies of vitamins and
    minerals.

28
Continued
  • People with food sensitivities, which include
    food allergies and food intolerances, may require
    special diets. A food allergy is a response by
    the immune system to the proteins in certain
    foods. Symptoms of food allergies appear suddenly
    and can be severe. People with allergies to
    certain foods should avoid those foods. A food
    intolerance is an inability to digest a
    particular food or food additives. Symptoms of
    food intolerance can be harder to recognize than
    symptoms of allergies.
  • Athletes need a well-balanced diet with the
    recommended amounts of carbohydrates, fats, and
    proteins. Athletes need to consume extra calories
    to fuel their higher level of physical activity.
    They should also drink plenty of fluids,
    preferably water, to replace fluids lost in
    perspiration during physical activity.
    Carbohydrate loading is the practice of greatly
    increasing carbohydrate intake and decreasing
    exercise on the days immediately before
    competition. This is not necessary for the
    average athlete.

Group Activity Special Diets
  • Individuals with special dietary needs
    include diabetics, vegetarians, and people with
    food sensitivities, and athletes. Health meals
    for special diets should include the nutrients a
    person needs while minimizing or eliminating
    foods that cause problems. Work with three other
    students. After each student in you group has
    filled in the information on the slide, share
    your answers with the rest of your group. You may
    want to modify some of your answers as you
    discuss them.
