According to National Institutes of Health, chewing gum has enhanced sustained performance in previous research. It is proven to enhance both alertness and attention. it also states that chewing gum can decrease stress levels as well as anxiety. I think that overall, this claim is true.

According to an article by Scientific American, "researchers say that gum increases the flow of oxygen to regions of the brain responsible for attention.". Which leads me to assume that this claim is correct.

The link you attached doesn't work for me, but I found it online using the quote you provided (I've reattached the podcast link below). The source is from 2013 so it's a bit outdated. However, I agree with your conclusion because I found more recent studies, such as the one from 2019 attached below, corroborating the original claim.
