What happens to the amount of water and fiber over time? Where are they going?
Water and fiber stay the same for both M'Kenna and a healthy person. They will pass through the digestive system.
Water and fiber stay the same for the M'Kenna and a healthy person. They will get absorbed in the digestive system.
Water decreases and fiber increases. This is because water gets absorbed and fiber will pass through the digestive system.
