I was diagnosed with IBS nearly 20 years ago, but suffered from it for many years before that diagnosis. I have BOTH constipation AND diarrhea. Loads of fun (not!)
Truth be known, if I have to suffer from one or the other, I'd pick diarrhea every single time. Constipation just HURTS.
My doc told me years ago to give up laxatives & I thought she was crazy. But she said I could take Milk of Mag anytime I wanted/needed but to experiment with how much was the "right amount" for me. Took me a while but I finally figured out that half a dose is my "right amount". I take it every night before bed. Rarely if ever suffer from constipation ever since.
If I eat red meat, I ALWAYS TAKE EXTRA MAGNESIUM - in the form of pills - usually 4, 6, or 8 per day, depending how much red meat I've eaten. I don't have this problem when I have chicken, fish, seafood, etc. Red meat is a known "constipator" (heh, I love making up new words

)
The transit time for all foods in your system should be about 12-16 hours. So if you're interested in testing your digestive timing, ingest some corn and time how long it takes to appear in your stool. The time from ingestion to the time the corn ceases to appear in your stool is the true transit time. To the extent that the interval is greater than 16 hours, you are constipated - stated bluntly, at least 2 (optimally 3) bowel movements a day are vital for optimal health!
Major danger can arise when we add meat products to a poorly functioning or constipated system. Red meat that stays in the system for over 16 hours begins to putrefy and becomes toxic. Not only will this create discomfort and intense odor, but food that putrefies in the stomach, colon, or intestines creates a breeding ground for viruses, bacteria, etc.
I'm not saying you should never eat red meat or that red meat is the only reason a person becomes constipated. Some people don't experience constipation from red meat at all; but there are scientific controlled studies out there that explain the whole thing. Google is your friend.
