Some animal studies showed that using diets including soluble fiber (oat bran) helped eliminate the C-diff infection sooner than a diet with insoluble fiber (wheat bran). Foods high in soluble fiber include: oats and oat bran, oatmeal, beans, peas, carrots, barley, citrus fruits, strawberries and apple pulp.
Similarly, it is easier for oxygen to gain 2 electrons instead of loosing 6 electrons: Oxygen Ion. The two gained electrons (purple dots) means that this oxygen ion has 10 electrons (-10 charge) and only 8 protons (+8 charge), giving the ion a net charge of -2. Symbolically, we can represent this oxygen ion as O -2.
The hydrogen atoms are attached to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side, where the oxygen atom is.
