NSD 225 Exam #1
What are the steps of the Scientific Method? - Answer-1. Curiously observe patterns and relationships
2. Review prior knowledge and form a hypothesis
3. Conduct controlled experiments, observations and research of prior data
4. Analyze data and observations
5. Draw a conclusion from the results
6. Share findings with the scientific community
What is the purpose of the Scientific Method - Answer-The scientific method ensures that conclusions
are accurate and reliable
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 are the three characteristics that make a nutrient essential? - Answer-1. A specific function in the
body has been identified for the nutrient
2. That function is impaired if the nutrient is removed from the diet
3. The same function is restored if the nutrient is added back to the diet
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 foods have the highest nutrient density? - Answer-Fruits, vegetables, and other legumes have the
highest nutrient density
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
What are the steps of the Scientific Method? - Answer-1. Curiously observe patterns and relationships
