related. - (answer)A calorie is the amount of heat needed to raise the temperature of 1 gram of

You bring your teenage nephew to lunch at the mall food court. He decides to get a soda and bag
of chips. You suggest he also try a vegetable and rice bowl as a more nutrient dense option. How
would you explain the difference between nutrient dense and empty calorie foods to him? -
(answer)Nutrient-dense foods are those with a high amount of vitamins and minerals, along with
the macronutrients that can be used as fuel. Empty calorie foods are high in calories but contain
little vitamins or minerals, so they have lower nutrient value.
Compare and contrast (i.e. explain the similarities and differences) between undernutrition and
overnutrition. Include the terms' definitions and how they influence health outcomes. -
(answer)Both over- and undernutrition have negative health consequences with an imbalance of
the consumption (or lack of) nutrients. They are both forms of malnutrition.

Overnutrition is the consumption of excess calories and fats (cholesterol/saturated), which
increases the risk of chronic disease and obesity, and can lead to toxicity.
Undernutrition is the opposite, when nutrient intake does not meet the nutrient needs of the body.
This can lead to slowed metabolic processes and deficiencies.
Which of the ABCDE's of nutritional assessment has to do with measurements of body
composition (weight, height, skin fold measurements, and body circumference)? -
(answer)Anthropometric
The health messages conveyed by the MyPlate illustrates the concepts of: - (answer)balance,

balance - (answer)calorie and portion size
moderation - (answer)increase consumption of some groups and limit the consumption of others
variety - (answer)consume all food groups
