The Role of Probiotics There are several trillion "friendly" bacteria (compromising over 400 species) in the human gastrointestinal tract; these types of bacteria dominate in a healthy gut. "Friendly" bacteria, called probiotics, reinforce the integrity of the intestinal lining as a protective barrier to prevent harmful organisms or materials from crossing into the body's bloodstream. Some probiotics have been found to secrete antimicrobial substances known as "bacteriocins," which inhibit harmful bacteria. By supporting the production of short chain fatty acids (SCFAs), which are by products of the fermentation of fibre, and thus lowering the pH of the gut, friendly bacteria create an unfavourable environment to pathogenic organisms.
Taking probiotics during pregnancy and administering them directly to the infant is associated with the development of a healthy immune system with a resultant reduced risk of allergies.
Gut Problems
Irritable Bowel Syndrome IBS is a common condition characterised by recurrent abdominal pain and discomfort, bloating and alterations in bowel function, diarrhoea/constipation, or a combination of both, typically over months or years. The condition is linked to imbalances in gut bacteria, stress, low fibre diets, high caffeine intake and food intolerance. Heartburn Heartburn occurs when the ring of muscle designed to keep the lower oesophagus closed fails to do so effectively and acid from the stomach backs up into the oesophagus, causing heartburn. Lactose intolerance Lactose intolerance is the inability to produce sufficient quantities of the enzyme lactase, which digests the sugar in milk called lactose. This is particularly common amongst those of Asian and African descent. Typical symptoms include flatulence and diarrohea. Ulcers Epithelial (lining) cells secrete mucus that forms a protective barrier between the cells and stomach acids; peptic ulcers result when this protective mechanism fails. Overproduction of acid, decreased mucus, the use of NSAI pain killers and infection with Helicobacter pylori are linked to the development of ulcers. Celiac disease Celiac disease describes a severe immune response to gluten, a protein found in wheat, barley and rye; symptoms include diarrhea, weight loss (or stunted growth in children) and fatigue. Problems related to the malabsorption of nutrients are characteristic. Presently the only effective treatment is lifelong adherence to a gluten free diet. Crohn's Disease Crohn's disease, also known as inflammatory bowel disease, occurs when the immune system attacks the GI tract; abdominal cramping, diarrhoea and frequent bowel movements are common symptoms. Although genetic factors are implicated in the development of the disease smoking and diets high in sweet, artificially fatty or refined foods may also play a role. Crohn's Disease is similar to Ulcerative Colitis, a condition characterized by inflammation of the large intestine; bloody diarrhea is the major symptom.
How to make sure your digestive system is healthy
Life-style tips Eat a diet based on whole-grains, fresh fruit and vegetables and high quality protein; consume caffeine and alcohol in moderation. Many people experiencing digestive problems may wish to follow an elimination diet, this involves removing foods you eat regularly for a period of 7-10 days. If symptoms significantly improve food intolerance may be causing your problem, if this is the case then only after about two months should foods gradually be re-introduced. Do not permanently cut out food groups without professional advice.
Supportive nutrients Digestive Enzymes Enzymes are protein molecules, they are considered catalysts, which means they make chemical reactions in the body happen faster. Enzymes are needed for digestion, they are present in raw foods; however since most of the foods we eat are cooked or processed in some way and since raw foods we do eat contain only enough enzymes to process that particular food, our bodies must produce the majority of the digestive enzymes we require. Taking a digestive enzyme supplement is useful for those experiencing symptoms of inefficient digestion such as flatulence and bloating. Those with specific enzyme deficiencies such as lactose intolerance or pancreatic insufficiency may also benefit. Acidic pH stimulates digestive enzyme secretion, therefore the addition of hydrochloric acid to digestive enzyme combinations will enhance their efficacy. Glutamine This amino acid serves as a source of fuel for intestinal mucosal cells. Vitamin A Vitamin A is required to maintain the integrity of mucosal cells.
Further support Senna This herb contains compounds that have laxative effects. Aged garlic Aged garlic extract acts as a prebiotic, enhancing the growth of "friendly bacteria". It also has antifungal properties.
If you are not digesting food effectively you will not gain adequate nutritional benefit from your meals; supporting the digestive system with the appropriate supplements and a healthy life-style will help you achieve and maintain optimal health. |
