The Science of Sugar Addiction & The Fifth Taste

The video explores the brain's role in food addiction, focusing on the LH VTA Loop, a neural circuit linked to sugar cravings. An MIT study using optogenics on mice shows how activating this loop increases food consumption. The video also discusses human cravings, suggesting they evolved to help find high-energy food. It then shifts to umami, a savory taste discovered in 1908, and its health implications. A Japanese study found that umami can stimulate saliva production, improving appetite in elderly patients. The findings could lead to treatments for food addiction and appetite loss.

What was the outcome of the study on elderly patients regarding umami taste?

How did the scientists help patients regain their appetite through umami?
