▶ True or False: Nutrition is the science that links foods to health and
disease. Answer: True
▶ Explain the difference between Internal and External drives that
influence our desire to eat. Answer: The internal drive is hunger and is
associated with negative sensations like churning, growling and pain in the
stomach. External drives have to do with appetite and are associated with
positive food sensations and lead us to eat when we are not hungry.
▶ You are at an "all you can eat'' buffet. On the first pass through the line,
you fill your plate with a large quantity of foods. After eating it, you go back
for a second portion of the foods you liked. However, the food is less
appealing the second time around, and you place a smaller quantity on
your plate because you feel full. Considering the physiology as you eat, (1)
explain what hormones are released (list specifically) as the stomach
stretches. (2) List the area of the brain that provides neural regulation and
appetite suppression to inhibit eating. Answer: As the stomach is filled and
stretches, hormones are released that cause satiety (Leptin, serotonin,
cholecystokinin (CCK). These hormones can travel to the brain
(hypothalamus) and activate the satiety center.
1. The hormones being released as the stomach stretches is leptin,
seratonin, and CCK. These hormones decrease hunger, in specific leptin.
They acitvate the satiety center in the brain which creates a sense of
fullness.
2. The area of the brain that provides nerual regulation and appetite
suppression to inhibit eating is the satiety center.

provides structure. Answer: FALSE: A mineral is an inorganic micronutrient
that regulates body processes and provides structure.

▶ List (A) the building blocks (or monomers) of PROTEINS, (B) at least 2
of their functions, and (C) at least 2 common sources of the nutrient in the
diet. Answer: A. Amino acids
B. Energy source, structure and regulation

soluble

that apply):
Lipids
