The Science Behind Sugar Cravings
49:19 - 1:02:30 (13:11)
Sugary foods and drinks amplify craving through dopamine pain-pleasure pathway and activation of neuropod cells in the gut, which send electrical signals to the brain via the vagus nerve.

The perception of sweet taste is important for the preference of sweet tasting drinks and foods.

Summary
The perception of sweet taste is important for the preference of sweet tasting drinks and foods. Animals and humans who lack sweet receptors do not have a preference for sweet substances.

Neuropod cells in the gut can detect the presence of sugar and send electrical signals through the vagus nerve to the brain via the nodos ganglion, creating a preference for sugar in our diet, even if it has nothing to do with our perception of sweetness.

Summary
Neuropod cells in the gut can detect the presence of sugar and send electrical signals through the vagus nerve to the brain via the nodos ganglion, creating a preference for sugar in our diet, even if it has nothing to do with our perception of sweetness.

Consuming sweet foods triggers the neuropod cells in our stomach and intestines, which then send signals to our brain to eat more of those sweet foods.
54:57 - 58:19 (03:22)
Summary
Consuming sweet foods triggers the neuropod cells in our stomach and intestines, which then send signals to our brain to eat more of those sweet foods. This, in combination with the dopamine pain-pleasure pathway, makes it difficult to resist sugary treats.

The use of 2-deoxyglucose shows that a third parallel pathway is related to the use of blood sugar, which reinforces our desire to eat sweet foods even more.

Summary
The use of 2-deoxyglucose shows that a third parallel pathway is related to the use of blood sugar, which reinforces our desire to eat sweet foods even more. This tool could be used to investigate what parts of the brain are active when eating certain foods.
