What are the three macronutrients? - Answer Carbohydrates
Proteins
Lipids
How many calories are each macronutrient? - Answer Carbohydrates - 4kcal/gram
Proteins - 4kcal/gram
Lipids - 9kcal/gram
What are the components that make up each macronutrient? - Answer Carbohydrates -
Carbon, hydrogen, oxygen
Proteins - Carbon, hydrogen, oxygen, nitrogen in amino acids
Lipids - Carbon, hydrogen, oxygen
What are Essential Nutrients? - Answer A group of nearly 50 nutrients that must come from
your diet. These are nutrients that your body can not make and can not function properly
without.
,What Carbohydrates are Essential Nutrients? - Answer None are essential
What Proteins are essential nutrients? - Answer 9 of the 20 amino acids used to build proteins
are essential
What Lipids are essential nutrients? - Answer only two specific fatty acids used to build lipids
are essential
Is water an essential nutrient? - Answer Water is the most essential nutrient
What vitamins are essential nutrients? - Answer All vitamins are essential
What minerals are essential? - Answer all minerals are essential
How do you determine a food's energy density? - Answer Energy Density: has a lot of energy
and calories per the amount of weight
To solve for energy density, calculate the given amounts of carbohydrates, protein, and lipids
that are in the food item, and multiply the carbohydrates by 4, the protein by 4, and the lipids
by 9. You then add up the three values to get the amount of kcals in the food.
How do you determine a food's nutrient density? - Answer Nutrient density: nutrient dense
foods are high in nutrients compared to the amount of calories
A food can be considered nutrient dense if the % daily value of a nutrient is higher than the
percent of calories
To solve for nutrient density, take the total number of kcals, divide it by the daily average of
2000 kcal, and multiply the answer by 100. If the answer is 5% or less, it is a low source of
nutrients. If the answer is between 10% - 19%, it is a good source of nutrients. If the answer is
20% or higher, it is an excellent source of that nutrient
How can you increase nutrient density? - Answer You can increase nutrient density by adding
fruits, vegetables, fat-free or low-fat dairy and plant proteins to your meals
, What are daily values? - Answer The % Daily value tells you how much one serving of food
contains of any particular nutrient. It is based on the 2000 calorie general nutritional advice diet
What determines the amount of calories you need? - Answer The amount of calories you need
depends on your height, weight, age, and activity level
How do you calculate the daily value? - Answer Divide the amount in a serving by the total
recommended daily amount and then multiply that number by 100
3g in a serving;
15g recommended per day
3/15 = 0.2
0.2 x 100 = 20%
What are serving sizes - Answer Serving sizes are on a nutrition facts label and are set to
reflect how much people normally eat.
Who sets serving sizes? - Answer FDA
Where are serving sizes found? - Answer Found generally at the top of food labels right below
the nutrition facts
What nutrients are often over consumed? - Answer Saturated fats
Trans fats
Cholesterol
Total sugars
Added sugars
What nutrients are often under consumed - Answer Vitamin D
Calcium
Iron
Potassium
