Nutrients
|
Components of food that are important for the
body’s functioning -Provide energy -Build, Maintain or Repair body -Support growth |
|
|
Six classes of nutrients
|
Six Classes:
Protein (PRO) Fat Carbohydrate (CHO) Vitamins Minerals Water |
|
|
Macronutrients
|
Provide energy (also known as calories):
|
|
|
1 gm protein provides ---------calories/gram.How many calories per gram is obtained from 1 gm of fat?1 gm of carbohydrate?
|
Protein (PRO) = 4 calories/gram
Fat = 9 calories/gram Carbohydrate (CHO) = 4 calories/gram |
|
|
----------------- and -------------- are needed in small amounts.
|
Vitamins ,Minerals
|
|
|
T/F.Only macronutrients (PRO, FAT, CHO) provide energy or calories.
|
TRUE
|
|
|
------------Provides 7 calories/gram;
May contribute to fat storage; Does NOT provide nutrients |
Alcohol
|
|
|
-Capsaicin in hot peppers
-Carotenoids like beta-carotene in carrots and broccoli |
Phytochemicals:Nonnutrient compounds
Found in plant-derived foods Confer color, taste, other characteristics on foods |
|
|
Organic Nutrients
|
-Carbon-containing
Four nutrients are organic: Protein Carbohydrate Fat Vitamins |
|
|
Must be supplied from food
Body cannot make for itself |
Essential nutrients
|
|
|
Condition caused by excess or deficient food energy or nutrient intake or by an imbalance of nutrients
|
Malnutrition
|
|
|
Consequences of Poor food/ diet choices
|
Overweight /Obesity
Hypertension Type 2 Diabetes Coronary Artery Disease Dental Caries Some Cancers Osteoporosis |
|

|
|
The Six diet-planning principles considered as the “building blocks” of a nutritious diet
|
Adequacy
Balance Calorie Control Nutrient Density Moderation Variety |
|
|
Which diet principle refers to this– foods provide enough of each essential nutrient
|
Adequacy
|
|
|
Which diet principle refers to this–choices do not crowd out one food type or nutrient at the expense of another
|
Balance
|
|
|
Which diet principle refers to this–foods provide the amount of energy one needs to maintain weight
|
Calorie Control
|
|
|
--------------is a measure of nutrients provided per calorie of food; foods of high nutrient density form the foundation of a well-planned diet.
|
Nutrient Density
|
|
|
---------------refers to foods do not provide excess fat, salt, sugar or other unwanted componentswhile ------------
refers to diet that includes different foods every day |
Moderation ;Variety
|
|
|
Why do we eat what we eat ?
|
Convenience
Emotional comfort Habit Social pressure Weight control Nutritional value Taste Preference Genetic inheritance Availability Economy Regional foods Values / beliefs |
|
|
Nutrition Quackery
|
A claim made that has no logical proof or perhaps cannot be supported by science
|
|
|
--------------------is the source of valid nutrition information.
|
scientific research.
If the claims made can be supported by science and are published in a reputable, peer-reviewed scientific or medical journal, then chances are the nutrition information is reliable. |
|
|
---------------is a type of Research Design where Studies of individuals yield observations that may lead to possible avenues of research
|
Case Studies
|
|
|
---------------is a type of Research Design where Studies of whole populations that can reveal a correlation; may be a first step in seeking nutrition-related causes
|
Epidemiological Studies
|
|
|
Define what correlation is?
|
A simultaneous change of two factors that suggests one may cause the other but does not rule out the possibility that both may be caused by chance or a third factor.
|
|
|
Which type of research design is this-Studies of populations where observation is accompanied by experimental manipulation of population members; an experimental group receives the intervention while the control (placebo) group receives none.
|
Intervention Studies
|
|
|
-------------------is a type of research design that is defined as Studies performed under tightly controlled conditions designed to pinpoint cause and effect; very often use animals as subjects.
|
Laboratory Studies
|
|
|
Where is valid nutrition information found?
|
Professional health organizations and their publications ,
-Government Health Agencies -Volunteer Health Agencies --Registered Dietitian (R.D.) |
