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
purpose of the scientific method - Correct Answers -we use it as a process to study
about our body and our needs and food claims
What are the three macronutrients? - Correct Answers -carbohydrates, fats, proteins
How many calories are in carbohydrates? - Correct Answers -4 calories per gram
How many calories are in fats? - Correct Answers -9 calories per gram
How many calories are in proteins? - Correct Answers -4 calories per gram
What components make up simple carbohydrates? - Correct Answers -usually have 1-2
sugar molecules
easy for your body to break down for energy or glucose
found in items that are sweet such as honey, sugar, syrup, etc.
What components make up fats? - Correct Answers -Trans fat: should be cut out of diet.
Comes from hydrogenating or adding hydrogen molecules to food
Saturated fat; Does not have any bends, caused by double bonds. Known to increase
cholesterol levels and can increase risk for heart disease. Found mostly in animal
sources.
Unsaturated fat: has at least one double bond causing bends in the molecule. Mono
unsaturated fats have one double bond while poly unsaturated fats have many.
allow you to store energy, cushion organs, make certain hormones, absorb fat-soluble
vitamins, and helps with cell-membrane integrity
, What components make up proteins? - Correct Answers -composed of essential and
non-essential amino acids
allows your body to grow, build, and repair muscle tissue
essential amino acids are required to ingest through your diet; non-essential is
produced in your body on its own
What are serving sizes? - Correct Answers -the amount of a food or drink that is
generally served to or consumed by the average person that are set by the FDA and
based on Reference Amounts Customarily Consumed
What nutrients are often overconsumed? - Correct Answers -sodium and saturated fats
What nutrients are often underconsumed? - Correct Answers -calcium, potassium, fiber,
vitamin D
What does enrichment do to food? - Correct Answers -Food enrichment is the practice
of adding micronutrients back to a food product that were lost during processing.
What are essential nutrients? - Correct Answers -A specific function in the body has
been identified for the nutrient.
That function is impaired if the nutrient is removed from the diet.
The same function is restored of the nutrient is added back to the diet.
How do you determine a food's energy density? - Correct Answers -number of calories
divided by the weight
energy density is the amount of energy or calories in a particular weight of food
How do you determine a food's nutrient density? - Correct Answers -if the % Daily Value
of a nutrient is higher than the percent of Calories a food is nutrient dense
In general, nutrient-dense foods are high in nutrient(s) compared to the amount of
calories.
What are daily values? - Correct Answers -the recommendation of nutrients the average
person should consume per day
How do you calculate the daily value of a nutrient to see if a person is getting enough of
that nutrient? - Correct Answers -divide the amount of a nutrient in a serving size by its
daily value, then multiply by 100
What does fortification do to food? - Correct Answers -Fortification adds additional
micronutrients not present (or present in small amounts) prior to processing.
What is considered "healthy eating?" - Correct Answers -A healthy diet provides the
body with essential nutrition: fluid, macronutrients, micronutrients such as vitamins, and
adequate fiber and food energy.
