  1. It is wise to eat the same foods every day.

    False, your diet will lack vaiety and probably will nto supply all the nutrients your body needs


    Milk is such a perfect food that it alone can provide all the nutrients a person needs.

    False, good in calcium and protein but contains very small amounts of iron and other essential nutrients.

    Cookies cannot be included in a healthy diet.

    False, any food can fit into a healthy eating plat. It's the total diet not individual foods that can either be good or bad for health.

    When it comes to nutrients, more is always better.

    False, Too much or too little of a nutrient is often equally harmful.

    A person's energy needs are based on his or her age, gender and physical activity levels.

    True

    From a nutritional standpoint there is nothing wrong with grazing on snacks all day, provided the snacks meet nutrietional neeeds without supplying too many calories.

    True

    If you don't meet your recommended intake for a nutrient every day you will ened up with a deficiency of that nutrient.

    False

    If a food label claims that a product is low fat, you can believe it.

    True

    Most dieticians encourage people to think of their diets in terms of the four basic food groups.

    False, dieticians today encourage people to think about eating from the five food groups.

    According to the government people should try to eat at least 2 cups of fruit and 2 1/2 coups of veggies totaling 8 servings a day.

    True
  2. ABC's of Eating for Health:
    • Adequacy
    • Balance
    • Calorie control
    • Moderation
    • Variety
  3. A diet that provides all of the essential nutrients, fiber and energy (calories) in amounts sufficient to maintain health.
    Adequacy
  4. A diet that provides a number of types of foods in harmony with one another, sch that food srich in one nutrient do not crowd out the diet foods that are rich in another nutrient.

    To avoid overemphasis on any food type or nutrient at the expense of another.
    Balance
  5. Control of consumption of energy (calories) a feature of a sound diet plan.

    To supply the amount of energy you need to maintain desirable weight (not more, not less)
    Calorie control
  6. The attribute of a diet that provides no unwanted constituent in excess.

    To avoid excess amounts of unwanted constituents, such as fat, salt, or sugar.
    Moderation
  7. A feature of a diet in which different foods are used for the same purposes on different occasions, the opposite of monotony.

    To consume different foods rather than eating the same meals day after day.
    Variety
  8. Refers to a food that supplies large amounts of nutrients relative to the number of calories it contains. The higher the level of nutrients and the fewer the number of calories the more nutrient dense the food is.
    Nutrient dense.

    (Potato chips are not nutrient dense, spinach is)
  9. A set of reference values for energy and nutrients that can be used for planning and assessing diets for healthy people, not for ill people.
    DRI - Dietary Reference Intakes
  10. The DRI aim to prevent nutrient deficiencies in a population as well as reduce risk for chronic diseases such and heart disease, cancer and osteoporosis.
  11. The minimum amount of a nutrient that will prevent the development of deficiency symptoms. Requirements differ from the RDA and AI which include a substantial margin of safety to cover the requirements of different individuals.
    Requirement
  12. The amount of a nutrient that is estimated to meet the requirement for the nutrient in half of the people of a specific age and gender.
    Estimated Average Requirement (EAR)
  13. The average daily amount of a nutrient ath is sufficient to meet the nutrient needs of nearly all (97-98%) healthy individuals of a specific age and gender.
    Recommended Dietary Allowance (RDA)
  14. We use the EAR (estimated average requirement) to set the RDA (recommended dietary allowance)
  15. The average amount of a nutrient that appears to be adequate for individuals when there is not suffcient scientific research to calculate an RDA.
    Adequate Intake (AI)
  16. The maximum amount of a nutrient that is unlikely to pose any risk of adverse health effects to most healthy people.
    Tolerable Upper Intake Level (UL)
  17. The UL exceeds the RDA and is not intended to be a recommended level of intake.
    The need to set a UL is the result of more and more people using large doses of nutrient supplements and the increasing availability of fortified foods.
  18. Foods to which nutrients have been ADDED, either bc they were not already present or bc they were present in insignificant amounts; foods to which manufacturers have added 10% or more of the daily value for a particular nutrient.
    Fortified foods
  19. Example of fortified foods:
    • Margarine with added Vit A
    • Milk with added Vit D
    • Certain brands of orange juice with added calcium
    • Breakfast cereal with added nutrients and nonnutrients
  20. People vary in the amount of a given nutrient they need.
    The challenge of the DRI is to determine the best amount to recommend for everybody.
  21. The DRI report on energy and the energy nutrients provides guidelines for the USA regarding the consumption of energy, carbs, fiber, fat, fatty acids, cholesterol, and protein

    It includes guidelines for physical activity as well.

    To meet the body's daily energy and nutritional needs while minimizing risk for chronic disease, consumption of the energy nutritrients.
  22. To reduce the risk of a chronic disease adults and children should spend how long doing physical activity?
    At least 1 hour every day doing a moderately intense physical activity (such as brisk walking) or 20-30 minutes 4-7 days per week in a high intensity activity (running or cycling)
  23. Daily energy expenditure can be cumulative so the 60 minutes need not be done all at once.
    Daily activities such as climbing the stairs at school or the office, housecleaning or walking to your destination from a distant parkinng spot can be combined with moderate physical activites such as brisk walking.
  24. The Dietary Guidelines for Americans provide science based advice to promote health and to reduce risk for chornic diseaes through diet and physical activity.
    They emphasize variety, calorie control, moderation and food safety, they also emphasize physical activity because it increases energy expenditure and helps in weight control.
  25. To avoid microbial foodborne illnes:
    • Clean hands, food contact surfaces, and fruit and veggies.

  36. Represents the average dietary energy intake that will maintain energy balance in a healthy person of a given gender, age, weight, height and physical activity level.
    Estimated Energy Requirement (EER)
  37. If you consistently build your diet by choosing mostly nutrient-dense foods that are low in solid fat and added sugars you may be able to meet your nutrient needs without using your full calorie allowance. If so, you may have what is called a........
    discretionary calorie allowance.
  38. Discretionary Calorie Allowance is:
    The balance of calories remaining in a person's energy allowance, after accounting for the number of calories needed to meet recommended nutrient intakes through consumption of nutrient dense foods in low fat or no added sugar forms. The calories assigned as discretionary may be used to increase intake from these groups that are higher in fat or with added sugars; to add oils, solid fats, or sugars to foods or beverages; or to consume alcohol.
