Uptake is not a simple process, it can be quite complex which involves, feedback mechanism’s, electrical signals, and special receptors (binding sites).
Many minerals and trace elements antagonise each other therefore caution is needed when taking supplements, it is quite easy to create imbalances in the body which could damage your health.
All this before nutrients start doing their job!
People with health problems very often suffer from digestion problems.
Related problems that will affect your health.
*Coeliac disease (Gluten Allergy) affects
*Digestion & Absorption.
*Food Sensitivities / Allergies.
*The action of Antioxidants.
*The importance of essential nutrients role to disease and disorder and the lack of them.
*Required therapeutic doses of nutrients to balance deficiencies, particularly when following a restricted diet.
*Possible breach of the blood brain barrier, by foreign bodies.
*Poor elimination, the first step, followed by digestion and absorption before assimilation.
*Absorption will not be well tolerated if your digestion is poor.
*Assimilation will not be effective when digestion and absorption does not happen efficiently.
A catch 22 situation.
Absorption (Uptake).
Foodstuffs once broken down into its various constituent parts are absorbed through the wall of the duodenum and small intestine.
Transporting sugars (carbohydrates) and amino acids (protein) into your bloodstream and lipids (fats) into your lymphatic system.
In a healthy person this process works quite efficiently, however, sugars and amino acids require some help, they are not necessarily absorbed unaided.
An energy dependent process known as ‘active transport’ assists the process of absorption, involving carrier molecules transporting nutrients through the epithelial cells of the gut wall, into the blood stream.
Similar to having the right key to fit the right lock, various carriers molecules match themselves to different nutrients, that combination may only pass through certain cells (binding sites), if the combination of nutrients does not match the site it will not be absorbed .
Vitamins and minerals are transported and absorbed in a similar manner, anywhere between the duodenum and the colon.
Minerals requiring an acid environment for absorption enter through the wall of the duodenum.
Trace elements like zinc are gastric acid free and ‘chelates’ (joins together like two pieces of a jig saw puzzle) with an amino acid before it can be transported across the gut wall.
Fat soluble vitamins are absorbed through the wall of the lower part of the small intestine, whilst water soluble vitamins are are absorbed through the upper part of the small intestine, the exception being vitamin B12, a large molecule that has to combine with a protein, produced in the stomach, known as the intrinsic factor before it is absorbed.
