Isn't slow food going through your body during sleep something that'll impact your sleep quality?

When you wake up you are basically fasting so your body is ready to take a hit. Slow food will go through your body faster when you eat it in the first half of your day.

I found the same food goes about as fast (on a rather empty GI tract) no matter when eaten.

Slow food takes about 24h for me (so even when eaten early).
