nutrition is the study of: - CORRECT ANSWER✅✅-the nutrients in food
-how nutrients are used in the body
-human behaviours related to food
food - CORRECT ANSWER✅✅any substance that your body can take in and adapt to enable you to stay
alive and gain nourishment. A carrier of nutrients
diet - CORRECT ANSWER✅✅food and beverages that you normally consume
nutrients - CORRECT ANSWER✅✅the components of food that our body needs for optimal functioning
what are the two groups that the six classes of nutrients are divided into? - CORRECT ANSWER✅✅1.
energy providing (meaning the body can use the energy they contain)
2. non energy providing
energy providing nutrients - CORRECT ANSWER✅✅carbs, fats, proteins
non-energy providing nutrients - CORRECT ANSWER✅✅vitamins, minerals, water
essential nutrients - CORRECT ANSWER✅✅must come from food because the body cannot make these
nutrients in sufficient quntities
ex: minerals, essential fatty acids, linoleic and linolenic acid
non essential nutrients - CORRECT ANSWER✅✅the body is able to make sufficient amounts to promote
health; therefore they do not need to rely on food intake
conditonally essential nutrients - CORRECT ANSWER✅✅the body can usually make enough to meet the
requirements of health, however during specific conditions (during periods of growth, injury or illness),
the body cannot make enough and therefore must rely on food intake
,ex: amino acid histadine (conditionally essential during periods of growth)
calorie - CORRECT ANSWER✅✅the amount of heat required to raise the temperature of one litre of
water (or one kilogram) of water by 1 degree celcius
how many calories per gram do fats, proteins, carbs, and alcohol provide us with? - CORRECT
ANSWER✅✅carbs: 4 Cal/gram
fats: 9 Cal/gram
proteins: 4 Cal/gram
alcohol: 7 cal/gram
(alcohol provides us with energy but is not a nutrient)
how do you find the percentage of calories in a nutrient? - CORRECT ANSWER✅✅if we wanted to find
the percentage of calories coming from fat, we would:
1. take the grams of fat and multiply it by our known value of cal/gram (this gives us the total number of
calories that fat provides)
2. next, divide that number by the total number of calories in the food to determine the percentage
coming from fat
when calculating the percentages of proteins, carbs, and fats, what should the percentage add up to and
why? - CORRECT ANSWER✅✅should add up to 100, since ALL calories come from carbs, fats, and
proteins
what are factors that play a role in the foods we choose? (12) - CORRECT ANSWER✅✅1. availability
2. cost
3. convenience
4. emotional
5. social
6. cultural
7. advertising/food marketing
8. habit

what are the benefits of being aware of food marketing? - CORRECT ANSWER✅✅1. recognize when
foods are being marketed to you
2. decide whether a food item is healthy by using food labels rather than relying on marketing alone
3. teaching those who are more vulnerable to food marketing about marketing techniques
what are the characteristics of a healthy diet? - CORRECT ANSWER✅✅adequacy, balance, calorie
control, moderation, variety, nutrient density
adequancy - CORRECT ANSWER✅✅getting enough nutrients to maintain health
balance - CORRECT ANSWER✅✅avoid getting too much of one nutrient at the expense of another
calorie control - CORRECT ANSWER✅✅consuming an appropriate amount of calories to maintain a
healthy body weight
moderation - CORRECT ANSWER✅✅ensuring that nutrients and dietary components are not consumed
in excess, especially in salt, fat, and sugar
variety - CORRECT ANSWER✅✅choosing a wide selection of foods each day and throughout the week
nutrient density - CORRECT ANSWER✅✅choosing foods that provide us with the most nutrients per
calorie
what should you do to help you eat healthier? - CORRECT ANSWER✅✅-be mindful of your eating habits
-cook more often
