Question

A friend is feeling very edgy about an upcoming test and is consuming large quantities of starchy, carbohydrate-laden foods. But she is also surprised by how much of this type of food she is eating. Sweet and starchy foods are comforting because carbohydrates increase levels of the neurotransmitter __________.

a. Serotonin
b. Dopamine
c. Acetylcholine
d. GABA

Answer 1

Carbohydrates such as starches found in foods can lead to increased levels of serotonin, a neurotransmitter that contributes to feelings of well-being and happiness.

Step-by-step explanation:

Sweet and starchy foods are comforting because carbohydrates increase levels of the neurotransmitter serotonin. When we consume foods high in starch, such as potatoes, cereals, bread, and pasta, our digestive system breaks these starches down into sugars, including glucose. This glucose is then used to produce serotonin in the brain, which is known to have a calming effect and can improve mood.

It should be noted, however, that low blood sugar levels stimulate a neurotransmitter that signals to the brain when the stomach is full, thereby reducing hunger. This is different from the mood-related effects of serotonin. The consumption of carbohydrates can provide a temporary feeling of calmness or happiness due to the increase in serotonin levels.
