This post isn't actually about orange juice. But is re: another kind... hehe!
We know that when we eat, the food gets broken down in our stomach. This is thanks to the gastric juice that breaks up the matrix that holds the cells together in the meat and plant food we eat.
Our stomach has very elastic walls and in those walls are many deep pits. And from those deep pits, this highly acidic gastric juice is secreted.
The juice contains hydrochloric acid, an enzyme called pepsin, and mucous. It's so acidic that it has a pH of 2. Basically, it can dissolve nails of IRON!!
As it tears apart cell matricies, it also kills the bacteria that may be on the food.
But, man, I'm still on the iron nails. What about my poor stomach?
Actually, our stomach is protected by a coating of mucus that helps protect it from the highly acidic environment. And, yet, our stomach lining DOES get eroded. Thousands of cells are being replaced every minute, and the entire stomach lining is replaced every 3-5 days!
