I noticed that a part of my stool was reddish orange? is it blood or food coloring? haven't seen this in the past couple days and i ate heinz ketchup yesterday and also ate tikka masala 2 days ago?

Food dyes can discolor stool. If you have any concern you should get your stool tested for blood. You can buy a kit at your local pharmacy and test it yourself or send it to a laboratory. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
