Like many on Whole 30 before me, I have been having trouble with diarrhea. Then I remembered something I learned from a nurse many years ago when I had diarrhea as a side effect from a medication. (The diarrhea had lasted two months, long after the antibiotic ended.) She recommended taking calcium to slow things down. It worked then, and it worked for me this month during my second Whole 30. After a week of diarrhea during my current W30, I took 600 mg. of calcium one night. The next day I took 600 mg. of calcium with each meal. I haven't had to take it since, and everything has returned to normal for me. I have also cut back on the fat, which may or may not have contributed to the diarrhea in the first place. I hope this helps someone else out there!
