Fiber is the most important ingredient that can help in natural constipation relief. You should eat as much fiber as you can. It helps in forming a soft and bulky stool. Good sources of fiber are most of the fruits and vegetables, especially green leafy vegetables. Excellent sources of fiber are broccoli, cabbage, carrots, cauliflower, zucchini, all eaten raw or thawed. Spinach, beans, whole-grain cereal all cooked are excellent sources. Fruits such as apples, peaches, tangerines, and raspberries will help increase the fiber content. Limit foods that contain no fiber such as processed foods, ice-cream, excess cheese and meat.
