The other day I did a quick experiment, and checked all the available loaves of bread at my grocery. There was not a single loaf that did not contain added sugar.
I imagine most people buy bread thinking that it's healthy, but they're basically just buying candy in bread form.
It's against Slacks ToS to recreate the main app offering so I'll be curious to see how long they can offer Slack support. I'm pretty sure they even killed the slack terminal client someone created awhile back.
Funnily enough, sugar is typically found alongside most grain based foods. It's in breads, cupcakes, etc etc. Ruling out grains consequently get's rid of a large source of sugar. The two are pretty intertwined.
