Because if anyone were to solve this issue, it would be a Golden Bear. Until then, we will continue carrying our DC food in reusable to-go containers, drinking tap water in reusable water bottles and recycling every plastic object we throw away. Going green is awesome, but as we move forward in these efforts, how far are you willing to go?
This week, Gawker offered us a solution to saving food … eat it again! Warning: This is a little bit gross. Drinking your own urine and eating your own poop is perfectly safe. Urine is sterile, poop is not, but they are your own bugs. There are no positive effects of eating your own poop that I know of. Hope this helps. Interesting question.
In theory, ingesting your own stool should not be harmful, as long as it "clean" i. Furthermore, there may be a theoretical minor health benefit in doing so.
Bacteria in the colon can metabolize non-absorbed food materials fiber and generate useful nutrients e. Re-uptake of these nutrients by ingestion of stool would give a second opportunity for absorption in the gut. In fact, coprophagy in mice a normal behavior helps to extract extra energy from food compared to mice that are prevented from coprophagy.
However, any theoretical biological benefit is heavily outweighed by our strong aversion to coprophagy. The primary reason for that is probably the unconscious awareness that stool is often a source of infections in humans because we do not get to ingest "clean" stool, but rather mixed stool from other people. So for the second exposure, the immune system will probably neutralise and kill the bacterium before it can multiply sufficiently to cause disease. But some food poisoning isn't caused by the bacteria growing in the individual, but by the toxins produced by bacteria in food that has been poorly stored.
The toxin damages your intestinal wall lining so quickly that you haven't got the time to mount an immune response to protect yourself. So, immunity cannot protect you and you could show symptoms on repeat exposure to the toxin.
Staphylococcus Aureus for example which can be found on the skin where it causes boils and spots, if that gets into poorly stored food, produces toxins which are heat and acid stable. So, the bug may not survive in the cooking process and the acid environment in your stomach, but the toxin does, and it can poison your intestine, causing diarrhoea and vomiting.
Harry - Intestinal damage and diarrhoea caused by the huge quantities of toxin present in the food, and produced by the bacteria multiplying in the food, can affect you even if you have acquired immunity to the bacteria.
This line is very informative: "The immune system will remember seeing the specific bacterium if it re-infects. In other words, if you had a pathogenic infection, then you are not going to "infect" yourself with anything that you've either already got, or recently recovered from. So the question has been answered.

If the bacteria that cause a bout of food poisoning came from your own intestines, will you be protected against illness?
