True or False.
If false, explain why it is false. Nutritional value and taste are often the 2

_correct answer_
False: Taste and texture are often the 2 most important reasons specific
foods are consumed in North America.
True or False: Nutrition is the science that links foods to health and disease.
_correct answer_
True
, Explain the difference between Internal and External drives that
influence our desire to eat.

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.
_correct 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.
