Spinach
Medical professionals prefer green leafy vegetables in the case of constipation due to higher amounts of fiber in these vegetables and other important nutrients too. Spinach has a good load of fiber, i.e., 4 grams per cooked cup, but also it has a gut improving mineral, magnesium. Magnesium helps to draw water into the digestive tract to lubricate the digested food and also further aid the digestive process. Because of the excellent qualities of magnesium, doctors suggest patients take their laxatives with magnesium to have more improvement in constipation.
