I’ve heard multiple times that it’s not okay to allow any food to go down the drain even with a garbage disposal, I guess because solids shouldn’t go down the drain. But we put a shit ton of solids down the drain through the toilet and that seems to be fine. Does the toilet go to a different sewage pipe then the sink? Or does shit have different properties that make it dissolve better?
It’s mostly because of fatty foods. The fats/oils tend to solidify in the colder temperatures of sewage lines, ultimately causing clogged lines.
Our waste though has generally digested a large amount of that fat, whether it gets built up on your belly and ass or whether a lot of it gets expelled in the sweat.
Edit: Also, ideally, bacteria helps a lot with breaking down human waste and toilet paper, making the waste easier to flow through the pipes.
Just wanna point out that dietary fat is not the same as body fat. You aren’t made of walnuts, so walnut fat doesn’t go straight to your belly. Just about all fat gets digested and converted into sugar, put in your bloodstream, and then, if there’s excess, converted into body fat. To leave your body, it then gets converted back into sugar, gets used as energy, and then the CO2 goes back into your blood and exhaled. Sweating more doesn’t cause fat loss, just water weight loss, and people losing weight aren’t expelling it out by ass.
Solid waste volume has surprisingly little to do with the actual food you eat. It’s primarily dead bacteria, 50-70% by volume. While some food makes it through, it’s mostly the nondigestable things full of fiber. And capsaicin.
This is not how lipids are metabolized. They are not converted to glucose right off the bat. Fats are broken down to monoglycerides to be absorbed, recombined to triglycerides and eventually chylomicrons, and transported to adipose tissue.
