Usually, a multiple preservative system, and /or the incorporation of hurdle technology, is needed to accomplish this goal.

Eating, Diet, & Nutrition for Constipation. How can your diet help prevent and relieve constipation? You can drink water and other fluids, such as fruit and vegetable juices and clear soups, to help the fiber in your diet work better. This change should make your stools more normal and regular.
A diet low in fiber may play a role in constipation. Insoluble fiber, which passes through the body almost unchanged, gives stools bulk and a soft texture, making them easier to pass. Foods that are high in insoluble fiber include whole grains, fruits, and vegetables. Try wheat bran, brown rice, or whole grain bread.
