Soylent & Neurogenesis

Neuroscientist, Sandrine Thuret in her Ted talk, “You can grow new brain cells, Here’s how” filmed 6/15, (link below) offered research and practical advice on how we can help our brains better perform neurogenesis—improving mood, increasing memory formation and preventing the decline associated with aging along the way. At the 8.28 mark she mentions that “Soft food” impairs neurogenesis while foods that require “mastication” i.e., chewing promote neurogenesis.



For what it’s worth, I’m in a psychology/neuroscience program, and I’ve never heard that chewing (or not chewing) has any effect on neurogenesis. It also seems like something that would be difficult to study scientifically because there could be so many compounding factors. That said, I haven’t watched the video yet (I’m at work), so I may be wrong. I’ll be interested to watch this when I get a chance, thanks for posting it.

Interesting. This came up on the forum back in april: [Chewing promotes neurogenesis. Bad news for Soylent?][1].

I also found an article from June 2015:

There are multiple neural circuits connecting the masticatory organs and the hippocampus. Both animal and human studies indicated that cognitive functioning is influenced by mastication.

For this, and other, reasons, I chew gum regularly. My long-time favorite is [Spry Xylitol Gum][3].

I could see using Soylent along with a sugar free gum. I do that already to keep fresh breath throughout the day. Besides, I’m not 100% soylent, I still love my rib eye and seafood.
