I have recently posted various information on Galactose, how it is used in chronic disease, etc. and gave you a number of case histories that knocked my socks off when I first heard about them. I received this from the researchers (University in Berlin) and medical doctors who are using it in practice, with outstanding success. It is so simple - and so successful. The Galactose Therapy is fairly new - I understand about two years in practice - . You have to switch gear for a moment from antibiotics to a simple dietary sugar. Only a 99.9% pure Galactose does the job.
This is long, but I would recommend you read every word if you are open-minded to a different approach. It does not cost an arm and a leg and it does not have to be done for a long time. Some people reduce the dose after a month. Some stay on it longer - depending on the existing damage.
For a more complete understanding, please combine this information with my previous posts which go into more detail. Dr. Reutter is nice enough to answer my questions and so I get more bits and pieces of info as he understands that I really really want to have all I can get.

Healthy sugars
Nutrition and General Sugar Biology
In the last 100 to 150 years the composition of our diet has changed just as drastically as our eating behaviour and our lifestyle. The relative proportion of animal protein, refined sugar and sweets, saturated fat and suchlike has shifted strongly at the expense of fresh fruit and vegetables.
Nowadays many humans eat too little fresh fruit and vegetables, the very foods that provide important minerals and vitamins. In addition, most of our present-day fresh fruit and vegetables contain a smaller proportion of certain vitamins and minerals than 30 years ago. Also, long-term storage, cooking and further processing, e.g. preservation and freezing, result in a loss of certain nutrients.
On the other hand, in our present-day high performance society, our bodies need much more than the recommended quantities of many vitamins, minerals and essential simple sugars. Fresh dietary vegetables are the ultimate source of all types of sugars. Plants exploit the energy of sunlight to convert carbon dioxide and water into simple sugars, known as monosaccharides. These simple sugars are then converted by the plant into a large number of other simple sugars, which can be used to synthesise complex information-carrying molecules, known as oligosaccharides and polysaccharides. The numbers and complexity of different sugars in fruits and plants vary, but they are so great that the exact number is not known. There are hemicelluloses, cellulose, pectin substances, resins and mucilages, which serve as components of water-soluble and water-insoluble polysaccharide fibers (structural components of the plant cell). More than 250 types of hemicellulose alone have been found in plant cell walls.
Hemicelluloses typically contain glucose and fructose, as well as the simple sugars galactose, mannose, galacturonic acid and xylose. Precisely these components formed the main components of the diet of our predecessors. But since we do not eat sufficient fresh fruit and vegetables, our diet contains insufficient free plant-derived mono- and polysaccharides.
We know that simple sugars with ring-shaped molecules, the hexoses (6-membered ring structure) and pentoses (5-membered ring), which are water-soluble, are partly destroyed by boiling. It is therefore not surprising that canned vegetables (e.g. canned asparagus) shows a loss of pentoses and hexoses. It can be assumed that, in addition to the loss of other water-soluble nutrients, hexoses and pentoses are also lost when fruit or vegetables are boiled or further processed.
Since insufficient attention is still not paid the dietary importance of sugars other than glucose, there has been hardly any study of the saccharide intake of our early ancestors. But we know that our ancestors did not use the same dietary sugar sources as ourselves. Our main sources of saccharides are refined sugar, milk (even after weaning), bread and pasta. The main utilisable nutrient yielded by these dietary components is the monosaccharide glucose.
Between 40% and 80% of our ancestors' diet consisted of plants. This plant food consisted of many different roots, beans, seeds, nuts, fungi, fruits, flowers and edible resins. A diet of this kind yielded daily about 100 grams of fibrous polysaccharid Nowadays this plant-derived component of our diet has fallen to 14%.
Dietary supplementation with the body's own components
Until recently it was thought that the various structural carbohydrates in the diet are degraded to glucose, which is then converted in the body to the different sugars needed by the cell. In the meantime, it has become clear that the presence of different sugars in the diet has various affects on our health. These facts can now be used to prepare simple and natural dietary supplements for medicinal use.
Of scientific interest are a large number of sugar molecules consisting of long chains with side branches. In recent years, these special polysaccharides, known as glycans, have acquired considerable importance for biologists and medical scientists. Their role in infections, immune reactions and intercellular communication is far greater then previously thought. Glycans become linked to protein molecules to form glycoproteins and to lipid molecules to form glycolipids.
Dietary sugars are not only an energy source. In particular, they are also structurally and functionally important in the body. The eating of fresh, unprocessed plant food containing free monosaccharides and polysaccharide fibers confers many health advantages, like protection from diabetes, heart disease and cancer. The health advantages of a diet with monosaccharide-containing foods are receiving increasing attention.
The advantages of a diet rich in polysaccharide fibers is lie mainly in the ability of the fibers to bind toxins, to provide ballast material for improved intestinal function, to improve the uptake of nutrients (positive effect on blood sugar level) and to bind bile acids (decrease in blood cholesterol).
The most recent research further indicates that the health advantages of saccharides in our diet are derived from the mechanical action of fibrous material. Free monosaccharides and polysaccharide fibers also serve as nutrients in the body. Thus polysaccharides can be digested and totally absorbed in the small intestine. Intestinal bacteria can cleave other sugars into their monosaccharide components, which can then be absorbed and utilised by the body. It has been shown that dietary mannose and galactose are used directly for the synthesis of glycoconjugates (e.g. glycoproteins and glycolipids) and must not necessarily be derived from glucose.
Using criteria similar to those applied to the study of vitamin and mineral supplementation, it has been shown that the modern diet no longer contains the necessary variety of sugars. It has also been shown that the human intestine is limited in its ability to utilise absorbed sugars. In view of the structurally and functionally vital role of these sugars, supplementation can be a definite advantage.
We now know that a diet rich in fibrous plant polysaccharides supports our immune system, prevents high blood pressure and high blood cholesterol, decreases the risk of heart disease and protects against cancer and obesity. Further, such a diet normalises blood sugar values and the structure and function of the gastrointestinal tract, as well as stimulating the formation of antibodies in the blood. It also protects breast-fed infants against infection of the gastrointestinal tract.
Uptake, distribution and metabolism of dietary sugars
Many sugars are responsible and necessary for the exchange of information between cells. This communication can lead to cellular activity, like the release of bioactive substances, removal of bacteria and cellular waste materials, or the blocking of docking sites for bacteria.
Sugars are normally taken up from the digestive tract by energy-dependent transporters. Some sugars, e.g. galactose and glucose in the human body, use the same transporter. Mannose appears to have its own transporter. In this way, sugars can regulate their own uptake and availability for their different metabolic tasks. These sugars play a big part in all body processes and functions, as evidenced by the fact that their distribution is changed in many illnesses, e.g. cancer, inflammatory conditions, bacterial infections, alcoholism, metabolic disturbances and diseases affecting the immune system. Often, the level of certain sugars shows a direct relationship with the course and severity of an illness.
Of particular note is the marked decrease of some sugars in cancer patients. This is all the more important, because we know that some sugars can restrict tumor growth and the spread of metastases.
Glycoconjugated sugars are metabolised by glycolytic enzymes. Certain intestinal bacteria appear to be more important than the liver for the metabolism of some sugars. Metabolic disturbances that prevent the conversion of sugars to their metabolic (i.e. utilisable) forms by appropriate enzymes can lead to serious illnesses, e.g. galactosemia. In arthritis patients, the level of galactose in plasma and synovial fluid is reduced. Conversely, administration of mannose or galactose can cure certain illnesses.
Biological activity of sugars
Glycoproteins or glycolipids, which contain one or more essential sugars, serve as receptors on the surface of cells and invasive disease-causing organisms. These glycoconjugated sugar groups function as docking sites for the receptors of other cells, enabling cell communication, leading in turn to a cellular response. The 8 essential sugars are mannose, galactose, fucose, xylose, glucose, sialic acid, Nacetylglucosamine and N-acetylgalactosamine. They are all easily taken up by the body and incorporated into glycoproteins or glycolipids.
Hitherto, glucose was assumed to be the most important sugar, but it has been shown that other sugars are more easily degraded. An intake of only glucose can lead to severe liver dysfunction.
All eight of the essential sugars have been shown to have a beneficial effect on the treatment of illnesses like cancer, arthritis, inflammatory conditions, bacterial and viral infections and disorders of the immune system. In particular, the immunomodulating activity of glycoconjugated sugars suggests that these sugars may have therapeutic value.
In this respect, the most active sugar is mannose. It activates macrophages, which release various bioactive substances, which are active against cellular waste materials, bacteria and inflammation. In animal experiments, administration of mannose has been shown to have very beneficial effects on wound healing. Mannose also inhibits the functions of neutrophils, which can cause further tissue damage by forming free radicals.
Galactose and galactose polysaccharides have very similar actions. Both inhibit Most of these essential sugars are also able to restrict the growth of cancers and/or metastases, while some, e.g. fucose and galactose, can do both. Glycoconjugated sugars stimulate macrophages to release interferon, which in turn activates the natural killer cells involved in the elimination of cancer cells. The reduction of metastases is due to the receptor binding of glycoconjugated sugars, which prevents the attachment of cancer cells.
Sugar Research
Sugar research is concerned with the functions of carbohydrates and sugar (glyco-) molecules in the body. Science first pinned its hopes on proteins for the development of cures for all possible diseases, but the limits of this approach were quickly reached. Sugars were looked upon purely as energy sources and even considered as harmful to the body. Sugar compounds are also essentially more complex and more diverse than proteins and therefore more difficult to study. Theoretically, 24 different protein molecules can be formed from 4 different amino acids. In contrast, 4 monosaccharide molecules can theoretically give rise to 124,416 combinations! This is possible because each monosaccharide has 6 binding sites, while an amino acid has only 2.
The sugar moiety of glycoproteins was not looked at closely until the 1990s. This opened up wholly new perspectives. It was found that sugars in all their different forms not only play a key role in all the important functions of the body, but that as nutrients they also have great potential in the fight against infections and even against cancer. Above all, sugars play an essential role in intercellular communication. The family of biomolecules known as carbohydrates contains the largest number of different molecular species on earth. They can therefore also store and transfer the most information. From birth onwards, carbohydrate molecules are responsible for intercellular communication and for important functions of the immune system.
Many diseases, like certain types of cancer, inflammatory processes like rheumatism, asthma, fibromyalgia, some heart and circulatory illnesses, and infections by microbes and viruses lead to altered sugar structures on the cell surface. This encourages the hope that it may be possible to use sugars therapeutically.
It has been shown that certain sugars, like galactose, mannose, fucose and glucosamine have an effect on the growth and spread of tumors. Successful clinical studies with cancer patients have shown that infusion with D-glactose results in a significant reduction of liver metastases and a general improvement in the condition of patients.
Glycoproteins are also involved in the attachment of viruses and bacteria to human cells during infection. Investigations have been reported on the extent to which sugar molecules can inhibit the binding of bacteria and viruses to cells and thereby prevent infection. Studies on living cells have shown that the addition of mannose and galactose or other monosaccharides can prevent or at least reduce this binding. A more recent experiment showed that a sugar compound isolated from birch can greatly reduce ear infections in children. The sugar acts by blocking the binding of the bacterium Streptococcus pneumoniae, the causative organism of these ear infections.
Knowledge of illness-specific glycoprotein structures can be applied therapeutically in immunotherapy by blocking the actual docking mechanisms of viruses and bacteria.
Glycoprotein research therefore offers many exciting prospects and raises many hopes. But at the same time, it presents many problems. Very many of these structures have now been investigated, but it is still not known exactly how they transfer their information and why, among millions of similar compounds, only certain structures are capable of transmitting this information.
In the future the use of glycoproteins in medicine will no doubt become standard practice.
Dietary science and sugar research must in future be rather strongly obligated to the exhaustive study of all possible medicinal uses of sugars.
We already know that certain sugars represent an entirely new group of nutrients. Thus galactose and mannose can be taken up and utilised directly by the body without first being metabolised to glucose.
Special carbohydrates therefore perform far more functions in the body than simply If, as it were, the ``sweet language of life'' is encoded in sugars, then the words of Hippocrates will be proved to be true: ``Let your food be medicine and your medicine be food''.
Increasing importance of sugar compounds in stress Stress during life cannot be avoided and it occurs in innumerable forms: psychological stress, lack of food or wrong food, operations, illness, environmental chemicals, addictions, lack of sleep, changes in the sleeping-waking rhythm, and climatic effects like heat, cold, high and low atmospheric pressure. We may be under stress even when we are not aware of it, because it is a normal component of natural cell growth and the ageing process.
Under stress, the body's resources become uncoupled from its normal functions (digestion, immune response, reproduction), as part of the fight or flight response to preserve life. Other bodily protective responses include, e.g. protection of cells against heat or chemicals. In the short-term, such reactions can help to preserve life, but there is much evidence that, in the long-term, suppression of body systems is damaging to health. Numerous studies document the fact that stress leads to increased sensitivity to viral infections, stomach ulcers and cardiovascular illnesses.
We know that it is important to keep stress as low as possible and to compensate for it with an adequate diet. So far, little attention has been paid to strategies for the optimisation of short-term measures against stress. Yet the nature of our immediate response to stress can mean life or death for our cells. The literature contains an increasing number of reports on the use of special sugar nutrients for optimising cell function.
These special sugars are needed for the formation of glycoconjugates, which can be looked upon as words in the body's language of communication. It is not therefore not surprising that they play a key part in the optimisation of our stress reactions. For example, mannose is contained in disaccharides, oligosaccharides and polysaccharides from the following sources: plant resins, seeds, plant sap, cacti and aloes, carrots, beetroot, cauliflower, cabbage, lettuce, parsley, rhubarb, Brussels sprouts, red cabbage and asparagus. These foods therefore provide not only energy, but also important materials for structural synthesis and information storage and transfer.
Since the digestive system contains cellular transporters for monosaccharides (glucose, galactose and N-acetylglucosamine share the same glucose transporter; mannose and fucose have their own sugar-specific transporters), it is concluded that the body can use these monosaccharides directly to synthesise the complex sugars of its information storage and transmission systems.
Some complex polysaccharides display many biological activities when ingested, indicating a significant direct uptake of these structures. Further, it has been shown that the human body possesses cellular receptors and plasma binding proteins specific for these molecules. Since these systems are physiologically necessary for the utilisation of complex polysaccharides, they have been retained in the course of evolution.
It is known that certain monosaccharides (e.g. glucose, mannose, galactose, fucose, xylose, N-acetylglucosamine, N-acetylgalactosamine and N-acetylneuraminic acid) are necessary for the synthesis of glycoconjugates. Glycoconjugates are proteins and fats with attached monosaccharides. In the human organism they are literally ubiquitous and fundamental to all vital information pathways, signal functions, biological reactions, etc. As a rule, our daily diet contains too little of these substances. Stress from environmental toxins and heat
One of the most important functions of glycoconjugates lies in their ability to protect us from environmental toxins. In the membranes of human cells, glycoproteins function as ``pumps''. They also pump toxins out of bacterial cells. In the human organism, they occur primarily in the digestive and excretory organs, where they are important for externalising toxins.
Heat stress, a further type of environmental stress, triggers the increased synthesis and glycosylation (transfer and attachment of sugars) of a family of ``heat shock proteins (HSP)'', which are thought to protect and repair cells during and after heat shock. Some of these HSP are known to influence crucial growth processes, such as cell division and protein synthesis.
HSP containing mannose are involved in immunisation against yeast (e.g. Candida albicans) infections. Certain glycolipids also appear to play a part in the stress-triggered increased synthesis of HSP.
In acute heat stress, ``prompt'' stress glycoproteins respond more rapidly, showing increased glycosylation within a few minutes. One of these stress glycoproteins, calreticulin, occurs frequently and is thought to protect cells by counteracting protein inactivation. Calreticulin operates together with another stress glycoprotein, to enable cell recovery from acute heat stress.
The lens of the eye contains a further glycoprotein (alpha-crystallin), which protects various enzymes from deactivation by chemical substances or heat. Some of these chemical substances, which are elevated in the blood of diabetics or kidney patients, are risk factors for cataract. Laboratory studies have shown that another glycoprotein, activin, appears to regulate cell division and maturation as a reaction to heat stress, thereby enabling cell survival.
Psychological stress
Through the interaction of many biological processes that are regulated by the central nervous system, the role of glycoproteins in psychological stress is very far-reaching and complex. One of these glycoproteins, stressin, contains large quantities of an Nlinked oligosaccharide, which consists mainly of molecules of sialic acid (a glycoconjugated sugar). Although its function is not known in detail, increased levels of a further glycoprotein [acute phase protein or alpha-1 acidic glycoprotein (AAG)] occur in the blood serum of humans and animals after being briefly stressed. For example, small children show an increased AAG blood level 4 days after an operation.
The effects of psychological stress on the immune system are particularly important, since glycoconjugates play such an important role in the regulation of immune reactions. For example, under examination stress, there is a marked increase in the serum glycoproteins known as immunoglobulins (antibodies), which are important for defense against infections. Similar stress conditions can even lead to alterations in immune cell function.
Age stress
Especially in old age and in metabolic stress situations, dietary glucose is no longer sufficient to supply the galactose needed for the galactose-dependent metabolic pathways of body cells. This affects the synthesis and the function of cell materials, e.g. structural elements, receptors, enzymes, water and ion channels and transport proteins (e.g. for glucose).
Cellular protein repair A particularly important aspect of the stress reaction is cell repair, involving structural and functional proteins. Different glycoproteins in the endoplasmic reticulum (ER) play key roles in the regulated protein repair resulting from stress in the ER. For example, glucose-regulated proteins (GRPs) and many other glycoproteins in plants and animals are produced in response to stress in the ER (interruption of protein processing as a reaction to stress).
An accumulation of under-glycosylated proteins in the ER activates genes that amplify the production of glucose-regulated proteins and other related glycoproteins, thereby enabling later glycosylation. Defective glycosylation of proteins of the ER also activates a small nuclear protein that helps to halt growth until repair processes come into operation. The level of a further ER protein, cyclin D1, is decreased by stress, accompanied by inhibition of cell growth until normal conditions are reestablished.
Calreticulin, which appears in the ER in response to stress, is involved in communication between the cell nucleus and the extracellular matrix. In injury or stress, the human intercellular binding molecule-1 (ICAM-1) guarantees the attachment of white blood cells (leucocytes, important for immune defense and wound healing) to the endothelial lining of blood vessels. P-Selectin is a cell surface glycoprotein that binds endothelial cells to white blood cells and blood platelets (also necessary for wound healing).
A further specific membrane glycoprotein ensures the attachment and aggregation of blood platelets (part of the blood coagulation system) during extreme bodily stress. The keratins are one of the protein families important for the structural unity and repair of stressed human cells, and their function is regulated by the N-acetylglucosamine glycosylation of many of its members during stress events like severe or viral infections. Glycoconjugates are also known to protect the gastric mucosa against acids, digestive enzymes and mechanical damage.
Glycoconjugates therefore play a significant part in the regulation of stress reactions. They are key components in intercellular communication. As such, they are fundamental to various complex biological systems, whose interaction and correct function protect against damage, stimulate cellular repair and aid removal of the toxins that accumulate in the cell in all forms of stress. An adequate diet containing glycoconjugated sugars and oligosaccharides needed to satisfy the stress-related increased demand for the synthesis of conjugates.
Special sugar biology
D(+)Galactose
As the free monosaccharide, galactose occurs in only small quantities in animals and plants. Like glucose, it is a hexose, a group that also includes mannose, glucosamine and galactosamine, the last two occurring mainly as their N-acetylated derivatives, rarely as their sulphates. Related to D-galactose is a monosaccharide called L-fucose, a methylpentose with the same configuration as L-galactose.
Traces of free galactose are notably present in milk. Quantities of free galactose similar to those of glucose are not available to any plant or animal organism. In the absence of an exogenous source, there is no detectable galactose in blood. It becomes detectable in blood and urine only in certain pathological processes. Galactose does commonly occur in animals and plants, however, in glycosidic linkage with other monosaccharides. Above all, it is an essential component of glycoproteins and of glycolipids like gangliosides. It makes a definitive contribution to the structure and function of these complex structures.
Dietary galactose We now know that galactose-containing glycoproteins and glycolipids are important for intercellular communication, in both health and illness. As cell surface receptors, galactose glycoconjugates are an essential part of the defense mechanism against cancer, inflammatory diseases and alterations in the immune system.
Most organisms use only a relatively small number of different sugars for the synthesis of their glycans. Human cells use, e.g. barely a dozen simple sugars for this synthesis. But every one of these monosaccharides possesses several binding sites, so that cells can synthesise not only linear, but also highly branched glycan polymers
Uptake
Many studies have been reported on the uptake of carbohydrates. Galactose is taken up by the human digestive system (jejunum), glucose by active, energy-dependent transporters (SGLT1 and GLUT1). Glucose and galactose compete for transport. To a certain extent galactose can be taken up via the oral mucosa, where it likewise shares an active uptake mechanism with glucose.
Distribution in the body[/
Galactose occurs in many body tissues and is one of the greatest contributors to the structure of biologically active glycoconjugates. Galactose is also a component of brain glycoproteins and glycolipids. It also occurs during the differentiation of germ cells into spermatozoa in the epithelial layer of human seminiferous tubules.
Galactose is also present in various structures of the skin, like epithelium, sweat glands and the endothelial cells of blood vessels. The proximal and distal tubules of the healthy human kidney contain glycogonjugates with terminal galactose residues. Such glycoconjugates also occur in the mucosas of the digestion organs, where they inhibit the absorption of cholesterol. Further, the mucosas of stomach cancer tumors contain reduced levels of galactose.
Galactose occurs in the glycoconjugates of the immune system, in immunoglobulin and macrophages, and appears to play a functional role in the etiology of immune illnesses like rheumatoid arthritis. Thus the immunoglobulins (IgG) of patients with rheumatoid arthritis show reduced levels of galactose residues; and the lower the galactose content, the more severe the illness. During remission, this decrease in galactose is reversed. Galactose deficiency in the IgG of rheumatoid arthritis patients would be expected to result in residual glycoconjugates with terminal Nacetylglucosamine.
These can bind to a mannose-binding protein, which in turn can lead to activation of blood complement and the initiation of an inflammatory process. Galactose levels may also be altered in other illnesses. For example, in severely ill patients, galactose is markedly decreased in the epithelial cells of the upper respiratory tract.
This may be an important factor in the occurrence of opportunistic respiratory infections in these patients, because cell surface carbohydrates of epithelial cells mediate the attachment of many pathogenic bacteria. In alcoholics, the proportion of galactose in red blood cells is decreased, indicating either an increased removal of galactose by hydrolysis, or inhibition of the synthesis of galactosecontaining glycoproteins and glycolipids.
Metabolism
Galactose is metabolised mainly in the liver. It is converted easily into glucose and used as an energy source, or it can be formed from glucose by the action of epimerase enzymes. Therefore a dietary source of galactose is needed to maintain the equilibrium mediated by epimerase enzymes.
Both galactose and mannose are important for the maintenance of adequate glycoconjugate synthesis, as shown by the fact that when added to the human diet both of these sugars are incorporated easily and directly into glycoproteins. Galactosyltransferase (GalTase) appears to play an important part in the etiology of rheumatoid arthritis (RA).
Abnormalities in immunoglobulin (IgG) glycosylation occur in RA patients, where, compared with non-affected members in the same age group, the glycoconjugates of serum and synovial fluid contain a lower proportion of galactose. This indicates that GalTase can regulate the degree of glycosylation during IgG synthesis and is therefore associated with the rheumatoid inflammatory process.
Biological activities
Galactose is involved in a whole series of biological activities. In addition to the role of galactose glycoconjugates in IgG, polysaccharides are powerful modulators of the immune system. For example, arabinogalactan, which consists of a main galactose chain with side chains of galactose and arabinose, activates phagocytosis, potentiates the action of the reticuloendothelial system, and displays antico
Numerous studies have shown that galactose inhibits tumor growth and metastasis. In studies on live mice, treatment with galactose drastically decreased the number of colonies of liver tumors produced from a lymphosarcoma. In humans with intestinal and stomach cancer intravenous galactose (1.5 g per kg body weight) inhibited the growth of liver metastases.
It has been shown that galactose-glycoproteins on the surface of tumor or host cells, which are involved in tumor cell growth, are blocked by competing galactose-glycoconjugates and autoimmune bodies, leading to the decreased attachment of tumor cells. It was further shown that the galactose polysaccharide, arabinogalactan, stimulates natural cell damage by killer cells and inhibits metastasis formation in the liver.
Galactose accelerates wound healing in rats, inhibits cataract formation in mice, and decreases experimental necrotising gastritis in rats more strongly than Antacidum or atropine. In humans galactose stimulates GIP release from the stomach, leading to increased insulin release and glucose utilisation.
Furthermore, dietary galactose appears to be important for maintaining the normal population of intestinal flora. Long-term feeding of galactose-polysaccharides at a level that does not cause digestive symptoms increases the number of Bifidus bacteria and alters the fermentation processes of the human gut flora. Oral galactose (25 g) stimulates the uptake of calcium in healthy volunteers.
[B]Why not lactose or lactulose instead of galactose?
Although lactose and lactulose contain about 50% galactose, they cannot replace galactose, even when added to the diet in double quantity. Lactulose is not cleaved in the body. There is no mechanism for the absorption of lactose and in certain population groups the majority of adults possess only very low concentrations of lactase in their mucosal cells, compared with the concentrations of other disaccharidases.
Since there is therefore insufficient lactase to cleave large quantities of lactose, undigested lactose continues to the colon, where it leads to the known serious side effects of lactose intolerance (unpleasant feeling of fullness, flatulence, uneasy disposition, dizziness, diarrhea). In fact, 20 to 25% of the world population suffer from inherited or acquired lactose intolerance. Lactose therefore cannot replace galactose as a micronutrient, and moreover it is harmful.
