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.

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.

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.
