14. Flaxseeds

Flaxseeds have been a go-to remedy for constipation for quite some time now, thanks to their natural laxative effects. They contain high amounts of soluble and insoluble dietary fiber which help in softening and moistening stools, making them easier to pass out. Studies have shown that adding flaxseed to your diet increases bowel movement frequency and decreases intestinal transit time, or the time taken for food to pass through the digestive tract.
