Nutrition and the Digestive Tract Newsletter

Issue: 9 - 09 May 2007
The interdependence of the digestive system and nutrients are very important for example some nutritional deficiencies reduce the efficiency of the digestive System. Efficiency of the digestive system reduced, so too is the intake of nutrients.
The oral cavity is the first part of the digestive system, it is important that we chew our food sufficiently as this increases the surface area of the food for digestion. In turn this improves the efficiency of digestion. The digestive system then continues in the pharynx (throat) and esophagus and into the "gut" region: the stomach, small and large intestines, the rectum and the anus.
Further along the digestive system there are many different types of problems, which interfere with proper digestion:
  • Inherited disorders( Lactose intolerance)
  • Gallbladder disease
  • Liver disease
  • Infection
  • Inflammation
  • Pancreatic disease
  • Ulcers
  • Diarrhea
  • Constipation
The mucosa lining the gastrointestinal tract is living tissue, which is the site of secretion of enzymes needed for digestion, and mucus needed to protect the tract. Any disruption of the mucosa reduces the efficiency of operation of these cells. When this happens the supply of nutrients from the gut lumen to the tissues is jeopardized.
Infection and inflammation are two of the most common disorders, which alter the properties of the mucosal cells. For example Gastritis, diverticular disease, and crohn’s disease all interfere with the efficiency of the mucosa.


Long-term diarrhea can reduce significantly the availability of nutrients to the tissues. The rapid transit time for food through the digestive system does not allow for its adequate digestion and absorption.


Reducing the flow of matter through the gastrointestinal tract also interferes with normal digestion and absorption of nutrients. It also may increase the time during which possibly harmful agents may attack the mucosa.
In summary you can see the importance of a healthy digestive system and bowel. A diet, which includes Moderate Lean Protein, Moderate complex carbohydrates, moderate fat and high fibre, has to be the best form of preventative medicine for the digestive system in the long term.

"I have a constant feeling of well being. I find that when I started taking the Natural HGH my sleeping really improved and I was waking up in the morning refreshed and full of energy. I now find that my energy is not only excellent but I maintain it throughout the day, not needing those afternoon naps anymore. I have also noticed that I don’t lose as much hair and it is thicker and healthier."
