How does my food come in different colors and come out brown/black
In: Biology
When colors mix they become brown and black also most food when it is decomposed it turns brown or black. Like rotten bananas etc a d you body basically decomposes food
The brown comes from the bile. It’s a liquid our body excrete in the stomach in quantity to digest food, we make approximately 1 liter per day. Bile is brown when digested and it color our poops.
People with bile tract obstructed have poop of other colors depending on what they eat, but usually white or beige colored poops.
The brown colour of stools is caused by bilirubin, a waste product that comes about when haemoglobin (from red blood cells) is broken down. It comes out of the liver in bile, and then makes it way out with the rest of the waste. The colour can also be influenced by what you eat, but generally when you mix all colours together you get brown/black
To add,
Your liver breaks down old and dead red blood cells – specifically, it’s recycling the iron in hemoglobin, and discarding the protein matrix that surrounded it. It’s why liver is so rich in iron. Now that the liver has this waste, it needs to get rid of it, and luckily there’s already a path to the dump, the bile duct!
Bilirubin is also known as bile pigments. Your poop is bleached white by your stomach acids, and take it from me – if you ever had a bad case of… You know… Your first solid… Solids, might very well come out white. TAKE IT FROM ME.
And that’s because when you return to normal there’s nothing impeding the path, so stuff can rush through without spending adequate time picking up bile pigments on the way.
If things are coming out black, that means either A) you’ve binged on Oreos, or B) you’re bleeding internally and should see a doctor. That sort of thing doesn’t just happen, so if it’s not strongly associated with a food stuff, you might want to be concerned.
