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.
Oxygen is carried within red blood cells by a compound called hemoglobin, which is able to bind up to four oxygen molecules and form oxyhemoglobin. Each red blood cell contains large quantities of this molecule, allowing them to carry around far more oxygen than needed to ensure that supply always meets demand.
