WGU D440 NUTRITION EXAM: HEALTH AND
WELLNESS THROUGH NUTRITIONAL
SCIENCE, 2025/2026 WITH
CORRECT/ACCURATE ANSWERS
Nutrition
The intake of food, considered in relation to the body's dietary needs
Nutrient Density
The nutrient density of an individual food is an important factor in
determining which foods to include in the diet. Nutrient density refers to
how many nutrients are present in a food, given the number of calories it
contains. It is a simple way to connect nutrients with calories.
Signs of good nutrition
Good nutrition is a significant factor in the body's ability to maintain a
state of wellness because each cell in the body is affected by the nutrients
that are provided to it. Signs of good nutrition include smooth skin, clear
and bright eyes, and resistance to infection.
Nutrition Status
Nutritional status measures and describes how well nutrient needs are
being met. When nutritional needs are met, an individual is considered
well-nourished and in a state of optimal nutrition.
, Primary Nutrient Deficiency
caused by insufficient dietary intake of a particular nutrient or nutrients
Secondary nutrient deficiency
the result of poor absorption or metabolism of a nutrient caused by an
interfering substance, a disease or condition, or an elevated requirement.
Nutrient Interactions
Nutrients work together within an integrated whole, providing energy,
building and rebuilding tissue, and regulating metabolic activities.
Interaction among nutrients is important for carrying out body functions
and can be overlooked when only one nutrient is examined at a time.
Traditional approach to healthcare
The traditional approach to health care focuses on treatment (i.e., wait
until there is a disease or condition and then treat or mitigate its effects),
instead of creating and maintaining wellness throughout life. Most chronic
diseases of adulthood (e.g., heart disease, hypertension, type 2 diabetes)
include dietary intervention as a part of the treatment plan.
Preventative approach to healthcare
Diet and exercise are the most important modifiable aspects of disease
prevention. A preventive approach to health care means that optimal
nutrition and wellness are sought from the beginning of life. The goal is to
support a healthy body throughout the life cycle to prevent (or delay) the
