What Is A Healthy Diet?

• To consume a variety of foods balanced by a
  moderate intake of each food
• Variety - choose different foods
• Balanced - select foods from the major food
  groups
• Moderation - plan your intake control portion
  size

19
The USDA Food Guide Pyramid

• To translate science into practical terms
• To help people meet the nutritional needs for
  carbohydrate, protein, fat, vitamins, minerals
• Provides a foundation to eating

20
The New Food Pyramid

• Encourages
• the consumption of healthy fats and whole grain
  foods
• avoiding refined carbohydrates, butter and red
  meat.

21

• Overloading the diet with refined carbohydrates
  is risky.
• The refining process removes vitamins, fibre and
  minerals and produces starch that is easily able
  to be assimilated.
• These carbohydrates considerably increase the
  level of glucose in the blood compared to those
  made from wholemeal flour, resulting in the
  increased risk of diabetes and cardiovascular
  disease.
• Boiled potatoes also appear in this category and
  therefore should be eaten sparingly, as the other
  refined carbohydrates.
• On the other hand the wholemeal foods that lower
  the risk of the above problems should be eaten
  regularly

22

• Fats also featured on this level
• Not saturated fats found in meat or butter
• Encourage monounsaturated and vegetable
  polyunsaturated ones

23

• Several Mediterranean populations, despite having
  a high percentage of calories in their diets
  provided by fats, do not have a higher risk of
  coronary disease compared to populations with a
  similar or even lower fat content in their diets
  (e.g. the Eastern Finns or Japanese) actually
  the risk was even lower.
