Failed digestion timing test?
Okay, I just went to the bathroom and saw a bunch of black dots in the toilet. I was like, what the fuckkkk, until I realized they were kiwi seeds from yesterday. But that means I completely digested them in about 10 hours, when the digestion test around the internet where you use beets says that 18-24 hours is maximal, and under that you might not be absorbing as many nutrients as you could. Should I be concerned or not?
Bloody. Fucking. Bollocks. This tests mouth to ass transit time, while most absorption takes place in the small intestine. Colon transit time can vary greatly depending on many things. Plus she's talking about food combining? It's true that proteins require acidic enzymes to digest and carbohydrates need amylase which is destroyed by acid, but that's why protein digestion happens in the stomach and starch in the small intestine after the acids have been neutralized.
Here's some data: transit time in the small intestine is greatest at about 5 hours. Stomach will depend on the size of the meal, and large intestine will depend on many factors, more than I know.
Here's a test: do you have undigested food in your stool? Food, not fiber. If not, you're probably fine.
