CORRECTION: Ideal pooping frequency is actually 2-3 times a day, not 1 time a day, I was originally wrong https://nutritionfacts.org/video/flashback-friday-how-many-bowel-movements-should-you-have-should-you-sit-lean-or-squat/

Normal frequency is between 3 per day to 3 per week, but normal doesn't necessarily mean healthy. Populations eating high enough fiber diets to reach that 2-3 times a day number have 1/50th the rate of heart disease, gallstones, and appendicitis, 1/25th the rate of diverticulitis, hemorrhoids, varicose veins, and hiatal hernia, and 1/10th the rate of colon cancer
