The more and more I learn about nutrition, the more I heard about the fact that if you are eating right it will show up in your poop. Yes I said it Poop! now lets get over it and move on.
There are three things your are looking for in your poop; shape, consistency, and color. Dr. Oz, whom many of you might remember from the Oprah show, has a short video called ""Poop Primer" which goes into detail of what your poop should look like with a scale of clay poop models ordered from 1 to 7, one being diarrhea and 7 being constipated.You should have a 4, and have a sort of S-shaped poop.
If you are on the lower end with diahirra then it could be because of irrtable bowl syndrome, allergies, or some other problem going on. If you are on the higher end of the spectrum and are constipated that means your poop does not have enough water in it. To help cure this problem you should have more water, and eat more fiber which you can find in a lot of leafy green vegetables.
Another thing you should look for is color. If it is brown or a little green that's ok, but if you poop is black that means there is blood in your stool. Also if its red it could be hemorrhoids or lower intestinal bleeding. Certain foods can also change the color as well. If you have some bizarre poop colors its always a good idea to get checked out by your doctor.
Ok, so now what does this have to do with being vegan you may ask. Everything! When you become vegan you will notice a major difference in your poop. When you first transition you might have a little bit of diarrhea at first from cutting out cheese and other dairy products, which work as natural binding agents. But once your body has gotten rid of that toxins from you previous diet you will enjoy plenty of those easy S-shaped healthy poops Dr. Oz talked about, and you will find that you will use the bathroom more frequently from the loads of fiber in your diet.
