You may have heard the phrase, “If the gut is not healthy, neither is the rest of the body”! In order to determine how well friendly bacteria work to balance the immune system (sinusitis is a hyper immune system), in 1987, Argentinean researchers performed a study using laboratory mice.
Unless you are going to eat a 100% raw food diet, you need to supplement with plant-based enzymes any time you eat foods that are cooked or processed, or packaged. Food enzymes can be isolated from pineapples, papayas, figs, pancreas and a mushroom called Aspergillus oryzae. This is why unheated, organic coconut oil is a great product for fighting infections. The statements and information on this website have not been evaluated bythe FDA and are not intended to diagnose, treat, cure, or prevent any disease. Many other companies manufacture and market digestive enzyme supplements, but only Enzyme Formulations, Inc. The diagram to the left is of the alimentary canal also known as the digestive tract and also shows other organs of the digestive system like the liver. After being swallowed, the food travels down the Oesophagus or esophagus, this is continually being damaged by the friction of food, so the epithelium is a few cells thick and secretes mucas to lubricate the food's passage.
The next place it enters is the stomach this is a temporary store, mixes the contents up and also is the site for a bit of digestion.
Enzymes are sensitive to temperature and pH, these must be at an optimum level so they work best. Below is a digram of the human gut wall, on the right are labelled the different layers that exist. The first actual layer is the mucosa, it has a layer of epithelium, made of epithelial cells, which have projections called villi.
Below this is a muscle layer, known scientifically as the muscularis externa, it is reponsible for peristalsis which moves food through the digestive tract. In the diagram you should also notice the capillaries, part of the blood network which takes absorbed food away. By the time everything reaches here, the food has been digested into small enough particles that it can pass through the alimentary tract lining and be absorbed into the blood. The food products pass into the blood stream through villi: these are small foldings of the small intestine that cover on its internal surface. The villi on their own increase the surface area, but the cells which make up the surface of the villus have their own small projections called microvilli (see diagram) these further increase the surface area which means that the digestion products can be absorbed more quickly. The villus has a supply of blood vessels this means substances absorbed can be transported to where they are needed more directly.
Triglycerides are a type of lipid; here you will learn how the body breaks down this molecule. Digestion begins in the duodenum where bile enters from the liver, bile salts make the big blobs of fat into small micelle droplets which massively increases the surface area and makes digestion much easier.
Also in the duodenum, pancreatic lipase this breaks the triglyceride into fatty acid and glycerol. These resynthesised lipids make proteins called chylomicrons, these enter the lacteals and travel through the lymphatic system, making it milky. THE TIMETABLE OF THE DIGESTIVE SYSTEMENZYMESFIND OUT MOREThe process of breaking down food into molecules the body can absorb is called digestion. The stomach is a stretchy, muscular bag that stores food and churns it around until it is a thick liquid. The small intestine measures 21 ft (6.5 m) and is the main organ of digestion and absorption. The lining of the small intestine is covered with microscopic projections called villi which dramatically increase its surface area.
The lining of the stomach and intestines secretes a thick, slippery liquid called mucus, which helps food slide along and protects the digestive organs from acid and enzymes.
The muscular walls of most sections of the digestive system contract in a wavelike pattern, known as peristalsis, to push food through.WHAT HAPPENS IN THE LARGE INTESTINE?
Cysteine proteases are enzymes found in some fruits as well as in other plants and animal products.
Protein-digesting enzymes, also called proteases or peptidases, are proteins that metabolize other proteins into smaller molecules. Protein digestion occurs through hydrolysis of the peptide bonds that join a protein's amino acids together.
The major protein-digesting enzymes in the digestive system are pepsin, trypsin, and chymotrypsin. Pepsin is the most important of this group, and it is part of an enzyme group called aspartate proteases. Another of the types of protein-digesting enzymes are called exopeptidases and are manufactured in the pancreas.
Another group of protein-digesting enzymes controls the circulation of proteins by degrading excess or damaged molecules.
Going off of this article, it has me wondering, are there any diseases out there where people have trouble digesting the enzymes of certain proteins? Large food molecules (for example, proteins, lipids, nucleic acids, and starches) must be broken down into subunits that are small enough to be absorbed by the lining of the alimentary canal. In the small intestine, pancreatic amylase does the ‘heavy lifting’ for starch and carbohydrate digestion ([link]). The digestion of protein starts in the stomach, where HCl and pepsin break proteins into smaller polypeptides, which then travel to the small intestine ([link]). The three lipases responsible for lipid digestion are lingual lipase, gastric lipase, and pancreatic lipase.
The mechanical and digestive processes have one goal: to convert food into molecules small enough to be absorbed by the epithelial cells of the intestinal villi. Absorption can occur through five mechanisms: (1) active transport, (2) passive diffusion, (3) facilitated diffusion, (4) co-transport (or secondary active transport), and (5) endocytosis.
Because the cell’s plasma membrane is made up of hydrophobic phospholipids, water-soluble nutrients must use transport molecules embedded in the membrane to enter cells.
In contrast to the water-soluble nutrients, lipid-soluble nutrients can diffuse through the plasma membrane. Active transport mechanisms, primarily in the duodenum and jejunum, absorb most proteins as their breakdown products, amino acids. The large and hydrophobic long-chain fatty acids and monoacylglycerides are not so easily suspended in the watery intestinal chyme. The free fatty acids and monoacylglycerides that enter the epithelial cells are reincorporated into triglycerides. The products of nucleic acid digestion—pentose sugars, nitrogenous bases, and phosphate ions—are transported by carriers across the villus epithelium via active transport.
The electrolytes absorbed by the small intestine are from both GI secretions and ingested foods.
In general, all minerals that enter the intestine are absorbed, whether you need them or not. Iron—The ionic iron needed for the production of hemoglobin is absorbed into mucosal cells via active transport. Bile salts and lecithin can emulsify large lipid globules because they are amphipathic; they have a nonpolar (hydrophobic) region that attaches to the large fat molecules as well as a polar (hydrophilic) region that interacts with the watery chime in the intestine. Intrinsic factor secreted in the stomach binds to the large B12 compound, creating a combination that can bind to mucosal receptors in the ileum. For those who believe the human body is the result of a series of random accidents, consider its amazing digestive system.
The products that the earth grows- fruits and vegetables- are exactly what our bodies need for fuel, cell growth, and energy storage. The esophagus is a 10 inch tube containing a series of muscles that contract in rhythm called peristaltic waves, forcing the food to the stomach, even if we are upside down! The stomach contains 35 million digestive juice glands that begin to break down the complex protein molecules of the food into amino acids. Then the ring muscles in the stomach begin a series of peristaltic contractions of their own so that every 20 seconds they force some of the chyme (partly digested food) into the small intestine. Were it not for the small intestine, we would starve because at this point only simple sugars and a few starches are ready for use by the body. The small intestine contains so many ridges and fingers (called villi) to absorb the nutrition chemicals that, were it smooth, it would have to be 600 times longer to accomplish the same task! The large intestine is 5-6 feet long and 2.5 inches in diameter and, among other things, reabsorbs 2 gallons of fluids into the body to avoid dehydration.
Question: what are the chances that all this perfectly engineered system came about by accident?
It blows me away that people believe in evolution when you look at the design of everything. But for good food to make you healthy, the digestive system diagram below shows that your digestive system must be healthy too. If you start with healthy food and all the parts of the digestive system work well, your digestive system will turn that good food into good nutrition. But even with good food, poor digestion cause digestive problems, like gas, heartburn, bloating, bad breath, diarrhea and constipation, or digestive disorders like Crohn’s Disease, GERD or irritable bowel syndrome. The first step to good digestion and relieving poor digestion problems is to know your digestive system parts and understand what they do. Mouth: Chewing starts breaking down the food and saliva lubricates and begins the digestive process of carbohydrates.


Pancreas: This is where a potent mixture of digestive enzymes is made for the digestion of fats, carbohydrates and protein. Small Intestine: The last stages of enzyme digestion take place in the small intestine, where almost all nutrients are absorbed.
Good digestion and the prevention of poor digestion problems often just requires eating more healthy raw foods and high fiber foods. Moss Greene has been studying the common sense principles of health and nutrition since 1979. By supplementing the body’s natural secretions, enzymes will help digest protein, carbohydrates, and fats in the intestines. Sufficient sodium enables the body to manufacture watery bicarbonates used to neutralize over acid stomach contents. Eating these foods provides the added fiber that will bulk up in your intestines, gently sweeping the colon clean of extra estrogen, hormones, toxins, waste debris of cellular metabolism and soak up excess toxins. When coconut oil is consumed, the body transforms its’ unique fatty acids into powerful anti microbial powerhouses capable of defeating some of the most notorious disease-causing microorganisms.
All raw food contains the proper types and proportion of enzymes necessary to digest itself.
Glands in the lining of the stomach secrete gastric juice, which contains pepsin and hydrochloric acid.
As food moves slowly along the great length of the intestine, it has plenty of time to break down properly. Even so, the intestinal lining does gradually wear away, but it continually renews itself by producing new cells, just as skin does.HOW DOES FOOD MOVE ALONG THE DIGESTIVE SYSTEM?
Harmless bacteria flourish in the waste and produce some vitamins, which are also absorbed. Meals rich in carbohydrates (such as sugar and starch) are digested quickest, and fatty foods take longest.ENZYMESMost chemical reactions in living organisms are controlled by enzymes. The molecules of each enzyme have a very particular shape which enables them to bind to a specific molecule in the body and make it react.WHICH ORGANS MAKE DIGESTIVE ENZYMES? These enzymes break down proteins, carbohydrates, and fats into the units they are made up of—amino acids, sugars, and fatty acids. Some proteases are a crucial component of the digestive systems of most animals, where they catalyze the breaking down of protein from foods into the amino acids from which these are made. Many of these enzymes are known as cysteine proteases, and they occur in many animals and plants.
Glucose, galactose, and fructose are the three monosaccharides that are commonly consumed and are readily absorbed. After amylases break down starch into smaller fragments, the brush border enzyme ?-dextrinase starts working on ?-dextrin, breaking off one glucose unit at a time. Chemical digestion in the small intestine is continued by pancreatic enzymes, including chymotrypsin and trypsin, each of which act on specific bonds in amino acid sequences. The most common dietary lipids are triglycerides, which are made up of a glycerol molecule bound to three fatty acid chains. However, because the pancreas is the only consequential source of lipase, virtually all lipid digestion occurs in the small intestine. Two types of pancreatic nuclease are responsible for their digestion: deoxyribonuclease, which digests DNA, and ribonuclease, which digests RNA.
As you will recall from Chapter 3, active transport refers to the movement of a substance across a cell membrane going from an area of lower concentration to an area of higher concentration (up the concentration gradient). Moreover, substances cannot pass between the epithelial cells of the intestinal mucosa because these cells are bound together by tight junctions. Once inside the cell, they are packaged for transport via the base of the cell and then enter the lacteals of the villi to be transported by lymphatic vessels to the systemic circulation via the thoracic duct. The small intestine is highly efficient at this, absorbing monosaccharides at an estimated rate of 120 grams per hour. Bile salts not only speed up lipid digestion, they are also essential to the absorption of the end products of lipid digestion. However, bile salts and lecithin resolve this issue by enclosing them in a micelle, which is a tiny sphere with polar (hydrophilic) ends facing the watery environment and hydrophobic tails turned to the interior, creating a receptive environment for the long-chain fatty acids. The triglycerides are mixed with phospholipids and cholesterol, and surrounded with a protein coat. Since electrolytes dissociate into ions in water, most are absorbed via active transport throughout the entire small intestine. Once inside mucosal cells, ionic iron binds to the protein ferritin, creating iron-ferritin complexes that store iron until needed. When blood levels of ionic calcium drop, parathyroid hormone (PTH) secreted by the parathyroid glands stimulates the release of calcium ions from bone matrices and increases the reabsorption of calcium by the kidneys.
Fat-soluble vitamins (A, D, E, and K) are absorbed along with dietary lipids in micelles via simple diffusion.
Chemical digestion breaks large food molecules down into their chemical building blocks, which can then be absorbed through the intestinal wall and into the general circulation. The nose overhangs the mouth so that aromas will add pleasure and flavor to the eating process. At the end of it is a valve to close off the stomach so that digesting food will not be forced back up. A series of muscles in the stomach churn the food so that it is mixed with the acid, yet the acid does not digest the stomach!
How would man survive during the long process of small random changes that ended up with the present system? Choose from the list of fruits, vegetables list and the list of whole grains to help keep food moving through the digestive system. She began writing professionally in 2002 as the Nutrition Editor for BellaOnline, the 2nd largest women's website on the internet and in the world. Our digestive system has the function of turning raw materials into the chemicals our body needs. A healthy intestinal tract is important in reducing the burden on the body from substances that alarm the immune system and cause it to be hyper, leading to inflammation.
By doing this, you address the causes of intestinal distress and help the digestive system improve and do its’ proper job in digesting foods and having a balanced immune system. Pepsin is an enzyme that digests protein molecules; hydrochloric acid kills germs and helps pepsin work.WHERE DOES FOOD GO AFTER THE STOMACH?
The size of the small intestine also maximizes the area of inner lining that food passes and the absorbtion of nutrients.HOW IS FOOD ABSORBED? From there, nutrients pass through the thin walls of the blood vessels in the villi, and into the body.WHY DON’T THE DIGESTIVE ORGANS DIGEST THEMSELVES? Others serve as catalysts of many basic cell functions, including hormone activation and deactivation, cell death, growth and immune system activation. Protein metabolism involves dividing proteins into their constituent amino acids, which are then processed by different anabolic pathways into either new proteins or other compounds. These enzumes break down proteins in the stomach and small intestine while other digestive enzymes metabolize carbohydrates and lipids.
This group catalyzes some of the chemical cascades that lead immune cells to attack antigens and cause the reactions necessary for blood clotting. This type of enzyme can completely digest a protein because it starts breaking the bonds between the individual amino acids at one end of the chain and continues doing this all the way down to the other end.
They are found in fruits such as pineapple and papaya and account for some of the intense acidity in the juices of these fruits. Not only is this article a great read for those who want to learn about protein digesting enzymes and the like, but it further reinforces what I've learned years ago. However, taking a supplement helps to create these enzymes, thus temporarily allowing them to digest it. Just food for thought. Chemical digestion, on the other hand, is a complex process that reduces food into its chemical building blocks, which are then absorbed to nourish the cells of the body ([link]).
At the same time, the cells of the brush border secrete enzymes such as aminopeptidase and dipeptidase, which further break down peptide chains. Pancreatic lipase breaks down each triglyceride into two free fatty acids and a monoglyceride. The nucleotides produced by this digestion are further broken down by two intestinal brush border enzymes (nucleosidase and phosphatase) into pentoses, phosphates, and nitrogenous bases, which can be absorbed through the alimentary canal wall. Each day, the alimentary canal processes up to 10 liters of food, liquids, and GI secretions, yet less than one liter enters the large intestine.
In this type of transport, proteins within the cell membrane act as “pumps,” using cellular energy (ATP) to move the substance. Thus, substances can only enter blood capillaries by passing through the apical surfaces of epithelial cells and into the interstitial fluid. The absorption of most nutrients through the mucosa of the intestinal villi requires active transport fueled by ATP. All normally digested dietary carbohydrates are absorbed; indigestible fibers are eliminated in the feces. Short-chain fatty acids are relatively water soluble and can enter the absorptive cells (enterocytes) directly.
During absorption, co-transport mechanisms result in the accumulation of sodium ions inside the cells, whereas anti-port mechanisms reduce the potassium ion concentration inside the cells. When the body has enough iron, most of the stored iron is lost when worn-out epithelial cells slough off. PTH also upregulates the activation of vitamin D in the kidney, which then facilitates intestinal calcium ion absorption.


This is why you are advised to eat some fatty foods when you take fat-soluble vitamin supplements. Intestinal brush border enzymes and pancreatic enzymes are responsible for the majority of chemical digestion. With the help of bile salts and lecithin, the dietary fats are emulsified to form micelles, which can carry the fat particles to the surface of the enterocytes.
It too contains muscles that not only keep the chyme moving in one direction, but also turn it three ways so that the chemicals added mix into the chyme and the digested molecules are absorbed into the blood stream. The type (protein, sugar, starch, fat) and amount (caloric value) of the major components present in the food determine the type and amount of the various enzymes found in the food. Pancreatic juice neutralizes stomach acid and contains enzymes that digest carbohydrates, proteins, and fats.WHY IS THE SMALL INTESTINE SO LONG?
Different types of proteases are classified according to their mechanism of protein breakdown. Exopeptidases catalyze very rapid digestion of proteins and can be damaging to the surrounding tissue if they leak out of the pancreas and into the bloodstream because of injury. Cysteine proteases are essential to the process of programmed cell death, hormone manufacture, bone development and many signaling cascades in humans.
In this section, you will look more closely at the processes of chemical digestion and absorption. Your bodies do not produce enzymes that can break down most fibrous polysaccharides, such as cellulose. The fatty acids include both short-chain (less than 10 to 12 carbons) and long-chain fatty acids. Almost all ingested food, 80 percent of electrolytes, and 90 percent of water are absorbed in the small intestine.
Passive diffusion refers to the movement of substances from an area of higher concentration to an area of lower concentration, while facilitated diffusion refers to the movement of substances from an area of higher to an area of lower concentration using a carrier protein in the cell membrane.
Water-soluble nutrients enter the capillary blood in the villi and travel to the liver via the hepatic portal vein. The monosaccharides glucose and galactose are transported into the epithelial cells by common protein carriers via secondary active transport (that is, co-transport with sodium ions). Despite being hydrophobic, the small size of short-chain fatty acids enables them to be absorbed by enterocytes via simple diffusion, and then take the same path as monosaccharides and amino acids into the blood capillary of a villus.
Without micelles, lipids would sit on the surface of chyme and never come in contact with the absorptive surfaces of the epithelial cells.
After being processed by the Golgi apparatus, chylomicrons are released from the cell ([link]). To restore the sodium-potassium gradient across the cell membrane, a sodium-potassium pump requiring ATP pumps sodium out and potassium in. When the body needs iron because, for example, it is lost during acute or chronic bleeding, there is increased uptake of iron from the intestine and accelerated release of iron into the bloodstream. Most water-soluble vitamins (including most B vitamins and vitamin C) also are absorbed by simple diffusion. Water absorption is driven by the concentration gradient of the water: The concentration of water is higher in chyme than it is in epithelial cells. They contain 32 teeth that bite, tear, crush and grind our food and a tongue that senses flavor and pushes the food under our molars without itself getting chewed (most of the time).
The small intestine itself produces intestinal juice that helps with final digestion of carbohydrates, fats, and proteins. Probiotics are food supplements comprised of billions of live microbial organisms that have numerous beneficial effects on our health. Better yet, if the plant-base enzymes are micro-blended with a mineral rich whole food such as micro algae, it dramatically assists good digestion in the stomach.
For example, olives and bananas are higher in fat and lipase, while peaches are higher in carbohydrate and amylase.
Researchers also believe that this type of protease influences key points in the cell cycle, affecting the different stages of cell growth and division. While indigestible polysaccharides do not provide any nutritional value, they do provide dietary fiber, which helps propel food through the alimentary canal.
Although the entire small intestine is involved in the absorption of water and lipids, most absorption of carbohydrates and proteins occurs in the jejunum. Co-transport uses the movement of one molecule through the membrane from higher to lower concentration to power the movement of another from lower to higher. The monosaccharides leave these cells via facilitated diffusion and enter the capillaries through intercellular clefts.
Short chains of two amino acids (dipeptides) or three amino acids (tripeptides) are also transported actively. Too big to pass through the basement membranes of blood capillaries, chylomicrons instead enter the large pores of lacteals.
Since women experience significant iron loss during menstruation, they have around four times as many iron transport proteins in their intestinal epithelial cells as do men.
The fats are then reassembled into triglycerides and mixed with other lipids and proteins into chylomicrons that can pass into lacteals. Our mouth also contains three saliva glands that produce a quart of the starch digesting chemical a day and help to wash the food down.
And He wants to deliver you from a far greater problem than starvation, the problem of sin.
Low stomach acid can be addressed with sufficient daily intake of organic sodium (Bland, pp.
Protein, carbohydrates, fat, and fiber are building blocks but they do not possess the energy (capacity to do work) necessary for biochemical reactions. Finally, endocytosis is a transportation process in which the cell membrane engulfs material. The monosaccharide fructose (which is in fruit) is absorbed and transported by facilitated diffusion alone. However, after they enter the absorptive epithelial cells, they are broken down into their amino acids before leaving the cell and entering the capillary blood via diffusion. Intrinsic factor secreted in the stomach binds to vitamin B12, preventing its digestion and creating a complex that binds to mucosal receptors in the terminal ileum, where it is taken up by endocytosis.
Other absorbed monomers travel from blood capillaries in the villus to the hepatic portal vein and then to the liver.
Compared to the control mice, macrophage activity was increased between three and four times, a clear indication of enhanced immune system activity.
By the time chyme passes from the ileum into the large intestine, it is essentially indigestible food residue (mainly plant fibers like cellulose), some water, and millions of bacteria ([link]). The monosaccharides combine with the transport proteins immediately after the disaccharides are broken down. The chylomicrons are transported in the lymphatic vessels and empty through the thoracic duct into the subclavian vein of the circulatory system.
All researchers concluded, that since activation in the body of macrophages is important in immune balance, oral supplementation might well be a new approach to stimulate the specific and non-specific immunity of the individual.
When raw food is eaten, chewing ruptures the cell membrane and releases the indigenous food enzymes. Once in the bloodstream, the enzyme lipoprotein lipase breaks down the triglycerides of the chylomicrons into free fatty acids and glycerol. Once liberated the enzymes begin to digest food, but their action is very limited in the foods they can work on.
These breakdown products then pass through capillary walls to be used for energy by cells or stored in adipose tissue as fat. Liver cells combine the remaining chylomicron remnants with proteins, forming lipoproteins that transport cholesterol in the blood. It has been widely researched and its’ abilities documented by scientists such as Dr.
It has powerful anti-carcinogenic properties and produces effective natural antibiotic substances which can deactivate eleven known disease causing bacteria.
However, enzymes cannot tolerate the high temperatures used in cooking, baking, microwaving, canning, and pasteurizing. I’m talking here about organic sodium or salt as found in green and sea vegetables, NOT commercial salt (sodium chloride) or sea salt. Candida albicans is a type of yeast-like fungus that can cause weakening of the immune system and infection known as candidiasis.
Once I receive your responses to the questionnaire, I can share with you how to get started on these products. This is an important factor to remember when comparing plant enzymes with the body's own digestive enzymes or with supplemental animal enzymes, such as pancreatin.
Pancreatic enzymes, whether produced by the body or provided as a dietary supplement, only work in the small intestine.
Quite simply, digestion is the process of breaking molecules apart with the addition of water hydrolysis. Conversely, plant and animal cells use the process of condensation—the removal of water—to form the long molecular chains that foods are composed of. In the initial stages of this healing process, I recommend that you use this tea once or twice a day for the first three months.
