Sugar and Brain Development

A March 2021 study by University of Georgia said, 

"Early life sugar increased Parabacteroides [a bacteria] levels, and the higher the levels of Parabacteroides, the worse the animals did in the task," 

"We found that the bacteria alone was sufficient to impair memory in the same way as sugar, but it also impaired other types of memory functions as well."

"We found that rats that consumed sugar in early life had an impaired capacity to discriminate that an object was novel to a specific context, a task the rats that were not given sugar were able to do," 

"Early life sugar consumption seems to selectively impair their hippocampal learning and memory,"

Memory. writing on paper -v- Smart Phone

A March 2021 study by the University of Tokyo found

"Actually, paper is more advanced and useful compared to electronic documents because paper contains more one-of-a-kind information for stronger memory recall,"

"Our take-home message is to use paper notebooks for information we need to learn or memorize,"

"Digital tools have uniform scrolling up and down and standardized arrangement of text and picture size, like on a webpage. But if you remember a physical textbook printed on paper, you can close your eyes and visualize the photo one-third of the way down on the left-side page, as well as the notes you added in the bottom margin,"

"High school students' brains are still developing and are so much more sensitive than adult brains,"

"It is reasonable that one's creativity will likely become more fruitful if prior knowledge is stored with stronger learning and more precisely retrieved from memory. For art, composing music, or other creative works, I would emphasize the use of paper instead of digital methods,"
