How Long Does It Really Take to Digest Food 😱

Only a machine can read with this speed.

@grok is this true?

The light you eat under can change what happens to your food. Your digestive system follows a daily rhythm. Light entering your eyes helps set that rhythm, so the same evening meal can meet a different digestive environment depending on the light you saw throughout the day. In one human experiment, a dimly lit day was followed by lower stomach electrical activity after dinner and more breath hydrogen overnight. That hydrogen is a clue that more carbohydrate escaped absorption in the small intestine and reached gut bacteria. Then researchers changed the light during an evening meal. Bright evening light produced more breath hydrogen than dim evening light. The pattern is striking: your gut responds to the light cycle surrounding a meal, not just the food on the plate. Get bright daylight during the day, and let evenings get dim.
